It all depend s on the experience & ages of the members. When ISM started we had Bee Warburton who helped on dwarfs & god the Joe Pye Weed garden people in Siberians. Now we have them for beardless & Lynn & Stephanie Markham for Borders and Miniature talls. Bob Sobek is back into hybridizing dwarfs after retiring. It was really funny trying to explain the photo of Snow Tree. Is it that white? yes. What olor are the lines? It depends on the soil, green in some, grey in others. I lost my voice at the sale as usual. Hope to have it strong again at the auction next weekend.
