I accidentally bought a nice roths in bloom and I'd love to make some Johanna Burkhardts. I can trade pollen from anitum, AM awarded Wössner Black Wings, sanderianum, haynaldianum, or maybe a few others in my pollen bank that I'm forgetting.
Dang! Sorry to hear about your plant.No, adductum seems to have disappeared from US collections. If anyone has them they're keeping them quiet. I had a couple from Popow and even managed to bloom one several years back but they never settled in and eventually died off.
