Hi Todd. Moments ago, I came across this old thread doing some research. I'm trying to determine which is the best of the dwarf, white, dicentras, for my zone 5, Midwest garden. Have you done much comparing of the 'alba' vs the 'snowdrift' or 'snowflakes' or similar varieties? I'm hoping for a little patch of long-blooming white flowers, to use in a partially shaded, front of a small berm location. I've grown the full sized versions, earlier varieties of the pink dwarfs, and I've had wild dutchman's britches in an old location, but this is my first time seeking out the dwarf, white hybrids. Any thoughts about which is the best for long-season of bloom and that won't fall apart during a typical, midwestern heat wave? Thanks much!
The alba form of eximia is probably the best...some growers have issues with the hybrids in hot summer regions...but even eximia may melt out during a heat wave. I am fortunate that my summers are relatively cool and all of these dwarfs blooms from late May to September.
