I had a pod that had two seeds in it(they're a bit of a bugger to crack open)i cracked one of the seeds,hitting the pod with a hammer to open it in the end,but potted both up anyway.One is doing brilliantly and is about 4 inches high,the other is sprouting,but tiny(i tend to think this is the one i cracked.)....So apart from finding a better way to open the pod than with a hammer,they're really easy and straightforward to grow from seed
