I am interested in harvesting seeds from Apocynum androsaemifolium in the western US as part of a nation-wide seed banking effort: Project Baseline (www.baselineseedbank.org). We have visited over 25 populations in California, Utah, and Colorado and have noticed that very few individuals are flowering or producing fruit. We visited the populations in June, July, and August. I am wondering whether anyone has any insights into the reproductive behavior of spreading dogbane in the west. I first thought the anomaly was in California only and attributed it to drought, but the pattern is repeated across multiples states. I have heard accounts that it is flowering and fruiting at expected rates in the Midwest and East Coast this year. I'm interested to hear any information you can provide. Thank you!
