Hello. I am new to gardening and to GardenStew. I planted straw flowers and now would like to know how to collect the seeds from them. They are quite tall and I love them. They only open up a night and have a nice smell. Can anyone direct me on how to collect seeds so I can plant them next year. The heads on a couple of them are almost like dandelion heads - the white, fluffy part. Thank you. Cat
