Topic: Helianthemum


  
  Helianthemum
Helianthemum nummularium, sunrose, is a semi-woody perennial shrub that remains a garden favorite year after year.
At six to ten-inches high with an 18-inch spread, Helianthemum function well in many garden situations: as the border of a perennial bed, as a "skirt" for the stems and foliage of bulbs, such as daffodil and allium, as a ground cover, or to drape over the edges of rocks or walls.
Helianthemum, once established, is exceptionally drought-tolerant, making it a perfect addition to the xeriscape garden.

  Helianthemum - Wikipedia, the free encyclopedia
Helianthemum (rockrose, sunroses, rushrose, or helianthemum) is a genus of about 110 species of evergreen or semi-evergreen subshrubs.
The flowers are 2-4 cm diameter, with five petals, white or yellow, occasionally tinged pink; in some species the flowers are bicoloured with a brighter yellow centre to act as a 'target' for pollinating insects.
Several Helianthemum species, and the numerous hybrids and cultivars derived from them, are widely grown as ornamental plants, popular in rockeries.

Classic rock garden plants, this variety of Helianthemum has a showy combination of greyish foliage and orange flowers.
I have been mostly unsuccessful in overwintering Helianthemum in the past, I was very happy to see this plant survive the winter of 1999-2000 (which was a mild winter here, perhaps explaining why it overwintered).
For an red-orange plant with similar effect in the rock garden, I now grow the hardy Sphaeralcea coccinea instead of these tender Helianthemums.

Foliage is evergreen, which is often bad news for plants in our Saskatchewan garden - cold, sunny winter days here can desiccate these types of plants so badly it will kill them.
We haven't had much success over the years over wintering any of the Helianthemum cultivars, so when I spotted this species in the Chiltern Seeds catalogue, thought I'd give it a try.
Had no seeds germinate in 1999, but managed one seed to germinate in 2000, which grew into the above plant (update 2003 - which has survived 3 winters now).
