The new millenium Delphinium. Much like a "Russel Hybrid" Lupine, these tough super hybrids withstand heat outstandingly well. I live in southern Maryland, which has clay arid soil that I've amended with loam. I've attached a picture during a heat wave. I had sewn this plant in January expecting it would be dormant by now, like any other Delph I've grown thus far in southern conditions. Watch crown for rot, especially in spring when transplanting plugs, crown must be above soil line. Powdery mildew late in season is common, also these hybrids aren't bothered by horrific humidity. Will update with pictures again next May/June!
