Lobelia Russian Princess Perennials

Growing Tips

  • Plant in deep fertile soil which is reliably moist in summer.(You can tell this is moist by the moss)
  • Lobelia grow well in sun or partial shade.
  • Some varieties are a bit short lived 3-4 years but as they are so spectacular it is worth splitting clumps or taking cuttings to get re-energised plants at least in alternate years.
  • Perennial Lobelia species make good herbaceous border plants

Lobelia to Grow

  • Lobelia Cardinalis has deep burgundy foliage and rich pinky purple or red flowers for hot coloured planting schemes. RHS is currently offering Russian Princess variety at £15 +  p&p (so the colours need to be rich).
  • A three foot high Lobelia x speciosa Vedraniensis flowers with the traditional 5 lobed blue-indigo flowers.
  • Hadspen Purple is a more compact variety that need to be planted in swathes for best effect.
  • Lobelia tupa has beautifully felted leaves and narrow tubular brick-red to orange flowers which are borne from mid summer on long racemes. It is also called the Devil’s Tobacco.

With hundreds of species, varieties and named cultivars the Lobelia family is large and wide ranging – have a look at the family for yourself.

Growing Convolvulus Cneorum

Madiera mch11 220

Convolvulus is synonymous with bindweed that grows in poor soil and is notably hard to eradicate. However there are some species of Convovulus that are worth a space in a Mediterranean style garden.

Convolvulus cneorum is a compact evergreen shrub with narrow, oblong, silvery leaves. The numerous flowers are funnel-shaped white flushed with pink when in bud.
Grow in well-drained soil or gritty compost in a sheltered spot in full sun.
The plants are not frost hardy.

Convolvulus White Ensign (Flash Seeds) is a dwarf Morning Glory with clusters of white, trumpet flowers with yellow centres!

Convolvulus Eneorum will withstand a north facing or east facing wall but also dislikes heavy frost. The grey leaved shrubs can grow to 3 foot high and wide.

Tips for Growing Ipomea – Morning Glory

ipomea

Ipomea indica the blue form of Morning Glory is a cool clear blue, a startling colour in the garden. As you would expect from a member of the Convolvulous clan it is a strong twisting and binding climber.

Uses of Morning Glory

  • The plant was originally used to produce cloth die.
  • The seeds should not be eaten as they produce hallucinations
  • In the garden they are very good for screening walls and ugly sites during summer.
  • They do not last as cut flowers.

Morning glory
Growing Ipomea Morning Glory.

  • Grow from seed and collect your own seed for next year.
  • Pick off dead leaves.
  • Try some of the other colours including rose and red plants.
  • Do not allow white Convolulous to grow as it spreads and throttles other plants

ipomea

  • Thompson & Morgan search for Morning Glory seeds and plants
  • Morning Glory ‘Carnevale di Venezia’ Ipomoea purpurea, Convolvulus purpureus,
  • A half-hardy annual which climbs to 6′ tall and flowers through summer with striped blue and pink blooms with intricate markings.

Flowers Grown for Your Vase

My perennial Phlox have been a good stalwart flower for cutting and filling a vase this last few weeks. I found the pink colours had more scent but all the Phlox seemed to drink copious amounts of water (I wondered if water and scent were related). The Penstemon in the same vase as the Phlox was not as successful as they had a far shorter life. Another successful long lasting cut flower is the Alstromeria. The Reds performed better than the yellows but both lasted over a week.

Our local garden center has been selling off Gerbera plants at £1 and I bought some just for the flowers that I could cut and put in a small vase. Even one flower in a bud vase looks good. There are now more buds to open and I think I got a good deal even though I will not bother to over winter the supposedly perennial plants. Gerberas come in a wide range of colors from light to dark yellow, orange, pink, brilliant scarlet and deep red ray flower centres.

The variety and colour of the Peruvian Lily or Alstroemeria, makes a colourful and long lasting display. Once established the plants continue to provide a good supply year after year. Pull the stalk up from the plant to encourage more flower stems. I grow my Alstroemeria in large pots.

 

Dahlias tend to flop a bit for me but Chrysanthemums can’t be beaten for longevity and impact.

Tip – Grow flowers that are easy to cultivate and flower in profusion but also last well when cut. Spray Chrysanthemums can give maximum pleasure for minimal outlay.

Growing ‘Just Joey’ Hybrid Tea Roses

Just Joey

I love the formal Hybrid Tea Roses like ‘Just Joey‘.
Just Joey is a hybrid, bred from Fragrant Cloud and Dr A J Verhage. These parents gave the rose glossy green leaves and very fragrant, orange blooms.
Blooms arrive in flushes throughout the season each having 30 petals so they have an open appearance.

Growing Tips

  • Remove old canes, dead or diseased wood and canes that cross, in spring.
  • Cut back the remaining stems by about one-third or a half.
  • As with all HT  roses give them a good feed in spring then every 6 weeks and mulch to keep in moisture.
  • When buying a bare rooted or container plant look for at least 3 strong stems.
  • Soak in water before planting.
  • Just Joey may  occasional repeat flower later in the season but is a slow starter in very cold spring weather.

Description of Just Joey

  • Rather a sprawling bush with grey green foliage. Grows 2’6″ tall and 2′ wide. Continue Reading →

Growing Campanula, Canterbury Bells or Bellflower

037

Alpine or border Campanulas come in many species and varieties.

Campanula lactiflora ‘Loddon Anna’ above was grown from seed distributed free to members by the RHS. It grows four feet tall and has many very attractive open bell shaped flowers. The flowers are arranged on a stem in a loose cone shape but with each of about 60 flower about an inch wide the effect is light and flowing. This species is commonly called the Milky bell flower and is a lilac colour.

Growing Campanula.

  • Most Campanulas bloom in June and July, but some varieties continue all summer.
  • Plant seeds or seedlings in May, though they can be sown in August and protected during the winter.
  • Most Campanula plants tolerate full sun but like some moisture in the soil. The smaller varieties grow in walls and rockeries.
  • Thompson Morgan have a fine seed collection.
  • There is a white Campanula persicifolia alba

Growing Solanum Crispum Chile Potato Tree

051

My Solanum Crispum is now about 8 feet high but is covered in purpley-blue blossom most of summer. I prune it to keep it at that height or it would go on to 20+ feet tall.

Plant Characteristics of Solanum Crispum

  • This shrub is related to the nightshade and potato family.
  • It is aka Chilean Potato Tree.
  • The flowers have an attractive yellow centre surrounded by blue flowers similar to potato flowers.
  • The base of the shrub becomes a bit bare after several years.
  • In mild winters, even in Yorkshire, it is evergreen.
  • It has a lax habit and I tie in some branches to a nearby hedge.

Growing Tips

  • I give it no special treatment of any sort, although it’s location is sunny.
  • Theoretically it likes alkaline soil and a high potash feed.
  • Propagate by layering, pegging a lower stem to the ground, or by semi ripe 3″ cuttings taken in late summer.
  • Despite being related to Potato all parts are all poisonous.
  • The variety ‘Glasnevin’ is the one to grow for prolific flowers.
