Christmas Roses for Christmas Hellebores

Christmas Roses for Christmas Hellebores

Christmas Roses will soon be with us in the garden. If you still haven’t removed the old leathery leaves from last year you can trim them off so the flowers are visible. After flowering lighter green leaves will grow to reinvigorate the plants roots.

Hellebores have a medieval reputation for preventing witchcraft and are also called the Christmas Rose or in some parts of the country Virgin’s Mantle. In addition to the traditional white Helbore niger there are many new varieties and colours to grow.

Selected Varieties
From the Lady series, Hellebore Red Lady, Hellebore Pink Lady, Hellebore Blue Metallic Lady, (a hybrid orientalis Hellebore )
Hellebore Picotee Double Ellen flowers a light delicate attractive pink and Double Ellen White has green outer to the petals.
Ashwood nurseries have a good list of specie and hybrid Hellebores
Hybrids from Thompson & Morgan
Gardeners Tips
Plant now in October for a magic touch of flower power when even snowdrops are still to flower
Plant in dappled shade with moist but not boggy soil.
Rabbit resistant which is a bonus near us.
Mulch in spring to keep up the humus levels.

Garden Orchids – Cypripedium & Hybrids

Garden Orchids – Cypripedium & Hybrids

Outdoor Orchids

Originally orchids were mostly found in tropical and subtropical areas and that is why they are foremost in our thoughts as indoor and houseplants.
What is less well known is that many orchids can also grow in areas where the temperature falls to -20°C.

One type of winter-hardy orchid from Thompson & Morgan is Cypripedium. They protects themselves by staying underground in winter but in spring the shoots appear above the ground and start flowering after just three or four weeks.

  • There are dozens of Cypripedium varieties which all have a spectacular inflorescence.
  • The Cypripedium flowers annually in May and June.
  • Cypripedium are named from the Dutch after a woman’s shoe.

How and Where to Grow Orchids in your Garden

  • The plants prefer a sheltered and shady spot but love the morning sun.
  • A north wall is a good spot but orchids also perform well in a border with shade from trees and shrubs.
  • They like a sandy soil, and combine excellently with ferns or little Hosta varieties.
  • Dig a hole and plant into moist soil.
  • If necessary, make the structure of the soil around the hole looser with sand or clay granulate.
  • When you plant your orchid directly in the garden, take care that in the first year that the spoil does not dry out.
  • After flowering, the plant makes new shoots and settles in its new spot.
  • Orchids do not need much fertiliser.
  • When the orchid has got a good spot in your garden it will last for many years.
  • After flowering it seems that the plant stops growing but under the ground it is making new buds anb roots.

Seasonal Tips for Outdoor Orchids

  • When resting, orchids are resistant to very low temperatures.
  • However, when the shoots start to grow, late-night frost can cause damage.
  • When late-night frost is predicted damage can be prevented by putting a bucket or big plant pot upside down over the plant and removed in the morning.
  • During the first year in particular you must keep an eye on night frosts because the plant has not yet acclimated to the climate in your garden.
  • In autumn the leaves of the orchid die off and the plant starts its winter rest.
  • The old dead foliage can be cut back to 5 cm above the soil.
  • Take care that you do not damage the new shoots when removing the old leaves or when weeding.
  • Do not cover the plant with peat but some old dry leaves are fine.
  • Often the tips of the new shoots are already visible
  • The plant can resist low temperatures and cold helps to start sprouting in spring.
  • In spring the plant sprouts again and under good circumstances produces even more shoots and therefore with more flowers. The cycle of the plant now starts again.

Primula Champagne White Rose

Primula Champagne White Rose

Primula Champagne white rose

We can all be caught by an impulse purchase as I was with this ‘Primula Champagne White Rose’ in the reduced section at a local garden centre. With my new found interest in the Primula family I thought I would buy this plant at half price even though they all looked as if they were done flowering for this season.

Treatment of Primula Champagne White Rose

  • I wanted to be able to divide any plant I bought and thus selected one from about 30 with what I hope were a couple of crowns.
  • I pinched out all the flower heads that were finished and cleared up some broken and damage leaves.
  • I was pleasantly surprised that there was a lot of bud still to open and I am keeping it on a windowsill near my computer for a week or so.
  • I will then take it out of the 6″ pot and molly coddle it with a bit of fibrous mulch and a weak thank you feed.
  • Hopefully I will be able to divide the separate crowns to produce more plants for next year

Information on Plant label Primula Champagne White Rose

  • The good quality printed label has a couple of rose coloured flowers with typical yellow centres. The edges on the photo are stronger red than on the actual plant but I do not feel misled.
  • Interestingly the label makes a virtue out of the Primula having been grown in the Lake District with a Union flag logo
  • ‘Primula Collection’ is the main heading Champagne White Rose is subsidiary but no reference to other items in the collection or who is responsible. (The retailer has put their name on a discount sticker £1 not £2.49.)
  • Height and spread 15cmx15cm 6″x6″ (Nothing to get concerned about although the leaves may die back a bit during summer before rejuvenating in autumn).
  • ‘Suitable for; plant in sun or shade in fertile, moist but well drained soil’ (well I do not intend drowning or starving the plant just riving it to pieces.)
  • Care Water well before planting and until established. (Since it will be late when planted out I will take care to water the plant)

Economic Christmas – Garden Stuff For Free

Economic Christmas – Garden Stuff For Free

When times are hard you need to use your imagination to enjoy a cheaper Christmas. Whilst these ideas are focused on the gardeners amongst us it is possible to invent garden themed ideas for children. Try word games with a floral theme or a winter wild flower walk (what can be found in the Christmas hedgerows?)

Low Cost Christmas for Gardeners

No one wants to be reminded of current economic woes and gardens are a great place to put such troubles behind us. Here are ideas for cheap presents and cost saving activities centred around gardening.

Free Stuff.

  1. Many local horse riding schools and stables have more manure than they can cope with. Many stables give it away free if you are willing to bag it up yourself. Look for the well rotted section often at the bottom and back of the pile. My family always thought it strange that Dad asked for ‘muck’ for birthdays and Christmas but it saved on presents and fertiliser cost.
  2. Seed catalogues make interesting reading in the cold, dark evenings and they will be sent out free by many companies.
  3. Take a trip to see public gardens or winter displays like these London Christmas Lights
  4. Gardeners are usually happy to give cuttings, seeds or plant offsets to friends and neighbours. As herbaceous plants are divided at this time of year look out for plants to scrounge. Public beds are often cleared of viable plants to make room for the next season and I have scrounged bulbs and plants that were destined for the council compost heap.
  5. A home made present can be treasured beyond price. Richard made me a pair of compost heaps on an E shape with moveable slats in the front from old fencing and some bought posts. Rustic tepees can be made from Hazel twigs and a willow screen could be fashioned depending on available material.
  6. Many wild life habitats can be made for free. Build something that will attract useful creatures. I buried an old dustbin as a pond which is now full of frogs. Tie hollow tubes together to make a bees nest or just pile up leaves and twigs for hibernating hedgehogs.
  7. Read internet blog sites like gardenerstips and think of them as free gardening magazines. You could set up RSS feeds and add them to favourites for a relative who was less confident about using the internet.

Good Value Presents

Membership of gardening related clubs can be very economic. See the list of great offers Garden society memberships or check with your local society.

  1. National garden centre gift vouchers and commercial garden centres like Wyvale vouchers allow gardeners to choose what they want, when they want it.
  2. Gardening books are available in great variety & quantity with most Charity shops also have cheap selection. There are only so many general gardening books that anyone needs. Monographs about a plant species or a good reference like Hilliers manual of Trees & Shrubs, the RHS plant or gardenfinder are a fair choice. Libraries are free and you can usually get them to order specific books on  youe behalf.
  3. As garden centres fill up their shelves with Christmas baubles they often put gardening dry goods on sale at a discount. Buy now for next season and wrap it as a present.
  4. Fruit trees and bushes are long term good presents as they will produce a valuable crop for many years. I name my fruit trees after relative as a memorial or to remember the gift.
  5. Split your perennial plants to make gifts and pot up strawberry runners for the same reason.
  6. Use conifer and holly branches for trimmings and a wreath.

Merry Christmas

What will you be buying for the gardeners in your family this Christmas apart from National Garden tokens? On the basis that it is the thought that counts, here are a few ideas to help with the thinking process.

Organic Matter
This covers seeds, plants, tubers and bulbs but also a prized gift like manure and compost.
Seed catalogues and web sites have a vast array of new and trusty old favourites but gardeners who specialise may want a say in the variety, size or appropriateness of a particular plant. Since most gardens can only cope with a limited number of varieties it is best to ask for a wish list or select something else.
Despite the comment above most gardeners would be happy to receive some summer flowering Lilies or other bulbs that can always be planted in a pot.

Equipment
Good quality tools make the jobs in the garden far more pleasurable. Better a good trowel than a cheap spade although a stainless steel spade would suit me down to the ground (literally).
Watering in the summer garden can be an issue and there are many watering devices for collecting and distributing the water to where needed. Strangely I don’t think you can have too many bits of kit to help you do this job so a gift from this range may be useful.
Just because a tool in the garden shed looks old, worn or damaged it doesn’t follow that a new one is wanted as it may be fun making do and mending.
Artistic gifts are a matter of taste and sculptures, garden features and ornaments need to chime with the recipient, the garden and the other stakeholders, so choose with care.

Media
Below are some gardening books to consider. All are available from Amazon by clickingh on the image.
membership of a society like the RHS, Alpine Gardens Socy, or Royal National Rose Society for example may be appropriate. Most offer year round benefits and even free seeds from some clubs.
Gardeners World subscriptions to the monthly magazine or Gardens Illustrated are other potential ideas click on the right.

Alpine House at Harlow Carr

Alpine House at Harlow Carr

standing-stones

Outside the 2009 Alpine House at the RHS garden in Harrogate are these new ‘Standing Stones’. I am interested to see if the planting links the new building to the sculptures but some how I doubt it. Possibly they are meant to represent the Alps or just be the start of a new part of the garden.

2012 update shows the stones front the much improved vegetable plots.

The new building, opened in May 2009 for the first time.  Is a tour de force and shows what finance and labour has been put in by the RHS and particularly the local Alpine and Rock Garden Group.

Tufa walls and more mature sink planters are now paying dividends.
The plant displays always include a good selection of alpines in flower.  Crocus and cyclamen were in profusion during November but below are some that took my fancy.

Why Grow Phlox divaricata ‘Clouds of Perfume’

Why Grow Phlox divaricata ‘Clouds of Perfume’

I have hopefully just bought a smelly plant for spring flowering in my rockery. Phlox divaricata ‘Clouds of Perfume’ is a woodland plant that also thrives in walls, borders or on banking. Versatile of what?

Wild Phlox

Facts about Phlox divaricata
It will grow 12″ tall and spread as a cushion 24″ wide.
This Phlox is semi evergreen and likes well drained soil.
It is also called wild phlox and grows as a weed in North America.
Other common names include Wild Sweet William, Louisiana Phlox, and Blue Phlox.
There are 67 species of annual and perennial Phlox according to wikipedia

Why I bought Phlox divaricata ‘Clouds of Perfume’
The flowers are powder blue, a cool shade I long to grow in my garden.
The bonus of a mass of flowers giving out a good scent was a second incentive.
Regular readers will know I am mean (I prefer to say thrifty) and I paid £1.50 for a large pot that was in an end of season sale. I have taken 6 rooted cuttings or divisions from the one plant and so I think I got a bargain.
Phlox Divaricata “Montrose Tricolor” Flowers at Rooftop Garden of Higashi-shinagawa Pump Facility
Other Varieties
Phlox divaricata’Blue Moon’, Phlox divaricata’Chattahoochee’is lavender coloured, and white varieties of Phlox divaricata include ‘Fuller’s White’ and ‘White Perfume’.
Phlox from Thompson & Morgan
Phlox Divaricata “Montrose Tricolor” above has variegated leaves and lilac-lavender coloured flowers.

Growing Hints
Pot grown plants should be watered well before planting.
Carefully remove from the pot and place in a prepared hole and firm the soil around the roots.
If the plant is pot bound tease out the roots or separate off some cuttings.
Water until the Phlox is established.

Phlox 'wagon wheels'
Phlox adsurgens ‘Wagon Wheels’ is another low growing perennial favourite of mine in the Polemoniaceae family.

Growing Red Hot Pokers (Kniphofia)

Growing Red Hot Pokers (Kniphofia)

over-red-hot-poker

Gardens look better for some variety in the height in the planting. I try to grow a variety of perennials including Red Hot Pokers to give some tall plants chance to shine. As part of the lily family these Kniphofia are sometimes called Torch Lily.

Red Hot Poker (Kniphofia) have flowered well this year and they throw up their well known spire of blossom in shades from deep red, orange, yellow and white even to a new greenish form (Kniphofia Green Jade).

Red Hot Poker

Growing Red Hot Pokers

  • Red Hot Pokers have long sword like narrow leaves and the flowers can last in a vase for up to two weeks.
  • The Kniphofia (Red Hot Poker or Torch Lily) needs abundant moisture during its growing period so good draining  soil rich in organic matter, is ideal.
  • Red Hot Pokers need full sun to flower upto 4 feet tall in mid summer. Prune the spikes  after blooming.
  • To propagate remove young plants from the edge of a clump  in spring or they can be grown from mixed seeds from Thompson & Morgan.
  • Provide adequate spacing to encourage clumping up as they may spread up to three feet.
  • Although Red Hot Pokers are drought tolerant they will do better if they are given plenty of water during hot weather.

Growing White Hot Pokers

  • Kniphofia known as Red Hot Pokers come in a range of colours and I like the cream or white.
  • This variety K. citrina is a stately lemon coloured spire of flower about 3 foot tall. They are good clump forming perennials with narrow strappy evergreen leaves.
  •  For other yellow flowers try Candelight, Little Maid (AGM) or Atlanta.
  • The sword like, strappy leaves, clump together well.
  • The plants look good when massed together in clumps.
  • Pokers are generally hardy herbaceous perennials -try Kniphofia Citrina a 3 foot lemon colour or giant 6 foot Royal Castle.
  • If space is limited Kniphofia hirsuta is 18 inches high and forms dense, tidy clumps. The flowers are good for cutting.
  • If the leaves are untidy in Autumn cut them down to half their height.
  • Kniphofia combine well with many shrubs, grasses and Yuccas. They like well drained soil in a sunny position.
  • White Hot Pokers can also look good in a Mediterranean gravel or paved area.

AGM varieties to grow

  • Kniphofia ‘Brimstone’ Slender spikes of golden-yellow from green buds.
  • Kniphofia caulescens Coral-red, fading pale-yellow.
  • Kniphofia galpinii Dainty spikes of very intense, rich orange
  • Kniphofia ‘Royal Standard’ Deciduous. Bright yellow, scarlet in bud
  • Kniphofia ‘Toffee Nosed’ Creamy-white tipped toffee-brown.
  • Kniphofia ‘Bee’s Sunset’ Deciduous. Soft yellowish-orange
  • Kniphofia triangularis Free flowering. Reddish-orange

Sarcococca Growing Tips

Sarcococca Growing Tips

I have grown this sweet smelling plant for several years thinking it was a Sarcococca but comparing this photo to others on Google images I am now having doubts.

saroccoa

Sarcococca Hookeriana aka “Himalayan Sweet Box” is evergreen growing and flowering in light shade.

Sarcococca confusa

Sarcococca Confusa aka Christmas Box or Sweet Box are evergreen shrubs with simple, leathery leaves and tiny, fragrant creamy-white flowers in winter or spring, followed by red, purple or black berries.

According to Thompson & Morgan ‘The winter blooms of Sarcococca hookeriana humilis emerge against a backdrop of lustrous, dark green leaves, with a powerful honey scent that will stop you in your tracks. The white, spidery flowers are followed by spherical, glossy black berries. Once established, this versatile, evergreen shrub needs little maintenance and tolerates a wide range of conditions – even difficult spots in dry, shade. A useful plant for borders, shady woodlands, and containers, or grown as a low, informal hedge. Height: 60cm (24”). Spread: 100cm (40”).’

Growing Cotoneaster as Small Trees

Growing Cotoneaster as Small Trees

We are familiar with Cotoneaster horizontalis in urban gardens producing masses of berries to feed the birds in late winter.
The larger shrubs and trees also provide a similar avian food supply and look very good in a larger garden.

Cotonester

Cotoneaster species number over 250 and the section devoted to larger trees and shrubs is called Chaenopetalum.
The flowers are produced in corymbs (flower clusters whose lower stalks are proportionally longer so that the flowers form a flat or slightly convex head.) The blossom has more than 20 floweras together. The creamy white petals open flat.
Many species are evergreen and generally larger shrubs but Cotoneaster frigidus are small trees up to 50 ft tall.

Small Tree Species
Cotoneaster Cornubia watereri group has red fruit that can weigh down the branches
Cotoneaster hybridius pendulus with glossy leaves
Cotoneaster watereri are a group of strong growing plants with orange – red berries loved by birds.
Cotoneaster ‘Exburiensis’ like many other species have leaves that turn red in winter.

Long Harvest Times

Long Harvest Times

You do not only want home grown vegetables when they are in mid season with all that a glut implies.
With some planning there are some vegetables that can be available most if not every month of the year.
Blue Cabbage

There is a cabbage for harvesting at all times. Sow indoors or outdoors depending on the variety. Plant out 6″ apart and get 10 good heads in a 10 foot row.

Radishes are another ’12 monther’. Sow under cloches for late autumn and winter pickings.

Swiss Chard Traffic Lights
Swiss Chard is a plant that will stand outside all year. Sow in May and pick on through.

Salad leaves are also good Jan-Dec but homegrown lettuce tend to be in short supply in January and February.

Spinach, Broccoli and Leeks miss out in January and February. Parsnips let you down in early summer but Cauliflower just about cover the full year.
