Anyone have any experience with Stainless Steel? I have 4 surviving Stainless Steels... 3 of blossomed true, but 1 is a MONSTER.. about 7-8' tall (seriously) and hasn't put out a single blossom all year. It blossomed once w/Dr. Huey flowers this spring.. has the rootstock taken hold? I actually have a couple of roses that happened that way.. a "climbing" Charisma that never blossomed but is over 6' tall and a Lagerfeld that blossomed w/Dr. Huey, but no Lagerfeld blossoms.
