Architectural Rheum not Just Rhubarb

Architectural Rheum not Just Rhubarb

rheum-flower

Ornamental Rhubarb

This sculptural plant has tall ‘frothy’ flower stalks pretty much like your Rhubarb when it runs to flower. Not surprising because Rhubarb is a variety of Rheum. Rheum palmatum ‘Atrosanguineum’ has very large leaves with a red underside and a rosey glow throughout the plant. They like plenty of humus in the soil.

Rheum Palmatum and Rheum Ace of Hearts are other herbaceous perennial varieties. Palmatum has large palm like dark green leaves that are purple-red beneath and creamy green to deep red flowers. It grows up to 7-8 feet and spreads 6 feet. Ace of Hearts has large heart shaped leaves.

This plant is grown on a steep slope so it can be viewed from underneath or above. The ground is moist most of the year so the rhizome is kept moist. As a herbaceous perennial it dies back in winter producing new spring leaves and early summer flowers.

Spring Shoots of Dicentra

Spring Shoots of Dicentra

green-shoots-of-spring

The economies of the world are waiting for a sign of the green shoots of a spring recovery. This Dicentra plant shows that not all good things are green and I love to seek out red shoots amongst my plants.

Other notable red shoots come in spring from the herbaceous Peonies and from Rhubarb plants but back to the Dicentra family or bleeding heart for a moment. The plants are easy to grow and reliable perennials whose clump grows each year. They resent disturbance so are hard to split for propagation but root cuttings from the edge of clumps are not too hard to strike.

Dicentra Varieties to Try Growing

  • Dicentra spectabilis is the variety above that will flower with dark pink heart shaped flowers. There is also a white version sold under the unsurprising name of Alba but this is generally Dicentra eximia.
  • Dicentra formosa has cherry-red hearts that dangle like lockets on arching stems above mounds of fern like foliage. Also nicknamed Dutchmans Breeches.
  • Bulb forming Dicentra cucullaria and Dicentra canadensis are cream or white in flower but retain the distinctive Dicentra fern like foliage.
  • Dicentra scandens is a yellow flowered climbing species that I not found to be hardy.
  • There are 19 species of Dicentra from America and Asia.

Growing Tips For Dicentra Formosa

  • The finer leaves grow well on the edge of woodland.
  • The grey leaved forms are OK under deciduous trees or shrubs but will stand more sun and can be used in alpine gardens.
  • Heavy clay soil needs improving with sharp grit and a granular feed in early spring.
  • The outer edges of plants are more vigorous than the centres. Use these to form new plants.

Dicentra cucullaria

‘Dicentra cucullaria (Dutchman’s breeches) is a flowering plant in the family Fumariaceae, native to North America. It occurs mainly in the eastern half of the continent, from Nova Scotia and southern Quebec west to eastern North Dakota, and south to northern Georgia and eastern Oklahoma; there is also a disjunct population in Idaho, Oregon and Washington. It typically grows in rich woods. The common name Dutchman’s breeches derives from their white flowers that look like white breeches.’
