Black Grass Ophiopogon planiscapus Nigresens

Black Grass Ophiopogon planiscapus Nigresens

Grass is designed to be green but gardeners being what they are they often want to get Black Grass.

Ophiopogon planiscapus Nigresens is often called Black Mondo. It is a rhizomus grass with delicate flowers.

The snowdrop sets off the grass which is easy to grow but occasionally slow to spread.
It makes a gothic garden feature or fits in well with a ‘black foliage and flower garden’.
The straplike, shiny black foliage grows in little tufts and combines well with many other plants.
Ophiopogon planiscapus Nigresens is not to be confused with Black-grass Alopecurus myosuroides or Black twitch. This is an annual weed native throughout the UK.

Plants and framed photographs are available from Amazon.

Acer Season 2012

Acer Season 2012

Maple trees or Acers have exceptional colour in autumn which is why tourists flock to New England and the eastern seaboard to see the flaming colours. Cold nights and warm days are the conditions that help turn green leaves to vibrant colours.

With the falling temperatures, the lush green colours of summer have been replaced with vivid reds, golden yellows and browns.

Leaves Autumn Amber

Why do Some Leaves Turn Red
Leaves naturally turn yellow as the chlorophyll breaks down and the green disappears but yellow can attracts sap-sucking aphids.
Some species of tree produce a bright red pigment into the leaves to confuse these insects.
Some trees are naturally red pigmented from the outset.

Osmanthus Shrubs and Uses

Osmanthus Shrubs and Uses

Osmanthus is an attractive genus of evergreen shrubs. The leaves are holly like with a leathery texture and spikes. The young leaves are green, red, cream or purple and below is a variegated example.
This variety O. hetrophylus is slow growing but can make a dense hedge or small tree. The flowers are sweetly scented in autumn.

Other Osmanthus and Uses

  • Osmanthus delavayi grows upto 6 foot tall and wide with fragrant white april flowers. It can be grown as a small tree.
  • Osmanthus yunnanensis ‘New Zealand Holly’ a fast growing large shrub with olive green leaves with flowers that can be a bit of a let down.
  • Osmanthus americanus ‘Devil Wood’ is a bit tender in the UK.
  • Osmanthus x burkwoodii which has small leathery leaves and fragrant white flowers in late spring. It can make a good hedge.
  • Osmanthus heterophyllus ‘Variegatus’ can be used as ground cover.
  • Osmanthus heterophyllus ‘Goshiki’ is an evergreen compact, fairly slow-growing shrub with dark-green, holly-like leaves.

Gardeners Top Tip
Osmanthus are cheap to buy when small, easy to grow and care for and are strongly recommended for a mixed border or ornamental woodland.

Choice of White Daffodils

Choice of White Daffodils

I have just bought and planted some white Daffodils for cutting next spring. I buy them from a nursery that allows you to pick your own bulbs from large wicker baskets and prices them by weight.

The main variety I chose was Mount Hood (div 1C) which has a white perianth that stands at right angles to a large white trumpet. Any hint of cream as the flower opens is soon relegated to a pure white.

white daffodil

Mount Hood dates back to the 1930s but remains the best known and most widely grown of the all-white trumpet daffodils. The flowers open creamy yellow and mature an even creamy white. They make a bright splash in early spring. Cream coloured Daffodils get whiter as the flowers age

White Daffodil

Another favorite is Thalia, a Div 5 Triandus narcissi with pure white flowers and a distinctive petals.

White daffodils

In the same division is Ice Wings and Silver Chimes which has a slight yellowing to the cup but both are best white daffodils.

daffodils / jonquils

The Jonquilla family are well scented but I am unsure of the variety above as the red stamen are putting me off.  Pueblo and golden Echo are thought to be the best virtual white.

I like this shot of another unnamed Daffodil. Look out for a new Poeticus called ‘Cutless’

Erlicheer daffodil in the morning

This Erlicheer is excellent for indoors with 15-20 double florets per s6tem. It may be flecked with some yellow but is essentially a white variety well known in Israel.

Blight in Blighty from Sky News

Blight in Blighty from Sky News

Veg growing gardeners get it in the neck for growing potatoes. Emma Birchley the East of England Correspondent for Sky News’ has got a new blight story, it is either feast or famine when it comes to the potato.

Late blight of potato

‘Allotment holders who fail to deal with blight-ridden potato plants have been blamed for spreading the fungal infection to farmers’ fields.

If it is not detected, blight can destroy crops and the spores can quickly spread 30 miles or more in the wind.
Tackle it the right way and it can be controlled, but the Potato Council says some home and allotment growers are failing to spot the signs in time.

“If someone on an allotment has a blighted plant, a single leaf on that plant can produce 120,000 spores,” said the organisation’s director Rob Clayton.

“They can blow around in the wind and in warm, wet conditions they can infect neighbouring plants, neighbouring allotments and the whole neighbourhood.”

The muggy, damp conditions of this summer have been the perfect breeding ground for the fungal infection.

Susanna Colaco has had an allotment in Cambridge since 1986. She has never known a year like it for blight. But she is angry that the finger is being pointed at growers like her.

“I think allotment holders are very responsible.
“On this site we purchase certified seed stock from our allotment trading hut and we are very careful that at the first sign of blight we inform all the members on site and ask them to remove foliage and to be vigilant.”

That foliage must then be burnt, deeply buried or binned. It can even go in the council’s compost bin as the contents are heated to a high temperature.

But infected leaves or rotten potatoes must never be put on the compost heap.

“If somebody throws a rotten potato on a compost heap at this time of year it can sprout … and it can kick off a whole cycle of infection from next year on,” said Mr Clayton.

Late blight, as it is known, or phytophthora infestans, is the type which destroyed vital potato crops in Ireland in the mid-19th century causing the Great Famine. A million people died.

Farmers expect to lose around 7% of their crop to blight, but this year the loss is predicted to be more like 10%.
And the usual £55m cost of coping with the fungal infection is likely to increase to around £80m.

Potatoes are already 11% more expensive than they were this time last year and the price is expected to rise significantly higher as the impact of the increased farming costs filter through to the shops and markets.’ Thanks Sky

Late blight of potato by Ben.Millett ‘This is a Dark Red Norland potato tuber that is infected with late blight (the disease that caused the Irish Potato Famine), caused by the pathogen Phytophthora infestans. If you start peeling a potato and see this, consider yourself lucky that the soft rot hasn’t set in yet. Although this disease looks bad (it is bad), what makes it particularly bad is that it allows other pathogens, such as the bacterium Erwinia carotovora, to get in and ‘ CC BY-NC-ND 2.0

Choosing Bold Colours in the Garden

Choosing Bold Colours in the Garden

One of the most interesting aspects of gardening is the combination of colours that can be achieved by accident or design.
Leaves and bark can play their part but it is the bold colours of some of our favourite flowers that take centre stage.

colour

Sometimes, we like the delicate, soothing pastel shades or the zen of a ‘White Garden‘ but, this doesn’t mean we always have to follow decorum and good taste. Sometimes its nice to just choose great impact colours which add life, zest and sparkle to the garden. The kind of colour combination that makes a passerby think – ‘hmm that’s interesting’

Plants I Grow from Cuttings

Plants I Grow from Cuttings

It is still not too late to take semi ripe and hard wood cuttings. Many perennials are short lived, like Penstemon, Pelargoniums and Pinks but they can be reinvigorated from new cuttings. Plants are not at their best in Autumn so results may not be perfect but I find it pays to experiment.

Semi-ripe cuttings should be hard at the base while the tip is still soft. Late summer to winter are good times to find material. Evergreens like Ceanothus, Choisya, Cistus, Erica, and Hebe have all grown well for me from cuttings.

Gardeners Autumn Cutting Tips

  • Take more cuttings than you need to cover losses.
  • Add perlite to your compost or use damp sand and peat
  • Hardwood cuttings of shrubs and trees can be taken and left outside under some shelter from a hedge. Buddleja, Cornus, Forsythia, Philadelphus and Ribes the flowering currant seem to do well overwintered as cuttings. Do not rush to look for roots give them time.
  • Pelargonium and decorative Fuchsia need to be over wintered away from frost and I find it easier to do this with soft cuttings rather than large plants.

Purple Coloured Flowers and Plants

Purple Coloured Flowers and Plants

Interesting colours are often seen in plants after a rain storm. The clouds and the temperature of the light can create some eerie shades. With all the rain in Yorkshire this summer colour in the garden has needed all the help it can get.

Iris

Purple Flower Selection

  • Pulasatilla vulgaris has a satiny rich, purple petals with a grey hairy underside. Also called the Pasque flower it is great for a spring purple if you want to avoid crocus.
  • If you like your purples to err towards the red spectrum then Clematis Haku-Oakan or Gipsy Queen are the climbers for you.
  • Malva mauritiana is a top purple perennial but Iris are my favourite. Try Mandarin Iris mixed with lime green Euphorbia.
  • At the end of summer the best Michaelmas Daisies will bloom in purples of all hues

Collection of Thoughts on Small Wild Bulbs

Collection of Thoughts on Small Wild Bulbs

If you can’t visit these bulbs in their natural wild habitat read the wild stories from a Latvian bulb collector Janis Ruskans.
Small Iris bulbs should be replanted and thinned every 2-3 years to retain flower power.

Iris reticulata

If you like Iris reticulata and a good travel yarn then you could do a lot worse than read ‘Buried Treasures: Finding and Growing the World’s Choicest Bulbs’ by Janis Ruksans

Book Cover
I think of Janis as the wild ‘ iris bulb man’ for the work he performs on breeding the various varieties in his Latvian nursery.

Janis Ruksans has been growing bulbs since age twelve and from 1991 has operated his own bulb nursery in his native Latvia. Janis is an expert specializing in rare and unusual bulbs. This book includes stories of his travels on several expeditions searching for new bulbs throughout Europe and Central Asia. He has also written a respected work on ‘Crocuses A complete guide to the genus’.

June garden 038 Iris reticulata

Unusually late these Iris reticulata normally bloom in the wild as soon as the snow melts on the mountain side.
Normally in the wild they remain dry during summer.
The bulbs should be replanted and thinned every 2-3 years to retain flower power.
