Sorry I missed this. I was out all day and just got back from visiting with Lynn.
Sometimes I've taken off the flower and put it in a warm window. Generally the anthers dehisce their pollen and it's pretty and fluffy. OK now TIME TO CROSS. Make sure you have protected the pod parent. The stamens should spread out like a rack of lamb and be slightly sticky at the tip.
Go for it! I have one heuff blooming but nothing that inspires me to cross. The cantabricums should be blooming soon. Am intrigued with their forms. Need that football-sized version though......
