  • Posted by sedumzz (Fairfax VA - Zone 7a) on Jan 7, 2022 8:00 PM concerning plant:
    Flower cluster size: A very branched bloom structure. Sometimes crested. Somewhat more cylindrical than conical in shape.

    Flowers seem to be double sometimes.
    Buds emerge deep indigo blue-purple with white rim. Flowers open as a gradient of deep indigo-blue purple, fading to a lighter lavender, then to white rim.

    Buds are somewhat broccoli-like.
