|Diascia integerrima Coral Canyon®|
This picture shows the upright habit, and delicate coral pink of this taxon. Diascia in general are well known and widely grown among keen gardeners--but most are really miffy annuals that need a great deal of cosseting--except for this one. Coral Canyon® is a landscape plant that loves to grow in full sun, in real soil, and it is a reliable perennial in Denver, given a modicum of good soil and water. Plant any one of the fifty or so Diascia that have been in cultivation in a typical garden bed, and most will poop out before midsummer, and few indeed will come back a second hear. I have had Coral Canyon® plants persist for a decade or more in an optimal spot. And I have seen it (ever so sparingly) growing around the country. The simple, sad fact is that this best of class is still essentially unknown by the great majority of keen gardeners in America: and more is the pity! The first time I grew Diascia integerrima it was the typical wild form, that grows a yard or more tall and flops. I remember Kelly Grummons of Timberline Gardens coming by in the early 1990's to Denver Botanic Gardens, admiring our large clump housed up against the then Alpine House, Kelly remarked "if we only had a compact form of this it would be a winner" (prophetic words, those...)

Same garden...from a bit further away: I love the contrast between the pink Coral Canyon® and the bright Lavender which was used to edge the beds.

If you haven't yet tried Coral Canyon®, I hope you give it a try! I doubt that given a good soil in sun that it will fail to impress you!
