Hi Shaw. Just found this thread.
I agree with both Cinta. All you have to do is plant them when you get home. The more little leave nodes you have on the stems, the more roots they will put out. If they have flower buds on them I would cut them off. They will make it difficult for the stems to produce roots. Sedum are very easy to start in this way. Can't wait to see them up and growing for you.
