54-08-08 = 'Midnight Blue' X ('Orangeade' X R. fedtschenkoana) The pollen parent is a white semi-double rose bred by Kim Rupert, who generously donated a plant to my collection several years ago.
This is a mightily vigorous seedling, having produced new basal growths recently that have grown from zero to three feet in only three weeks. I am pleased to note two things: 1) this plant has set seed easily using a variety of pollen parents, and 2) it is repeating bloom in flushes, where in its first year it did not bloom at all. One of its siblings has proven extremely easy to propagate and I will be testing this cultivar for ease of propagation soon as well. I think this has promise as a potential link to new kinds of shrubs for the modern, low-maintenance garden.
