  • Posted by KFredenburg (Black Hills, SD - Zone 5a) on May 26, 2020 9:22 PM concerning plant:
    The info on the database says that the bloom sizes of this plant is 2-3 inches, but mine almost always get under 2-3 inches. The zone we are in may have something to do with it.
    There have only been around 10 blooms I've seen that have gotten that big (hence why I said "almost always").
