Castor bean pods: how to tell if ripe
I saw a large number of red castor bean plants today in a distant park today. I have always wanted to grow these. The pods were still red. I picked a few anyway. Do the pods turn brown when ripe? I don't think I have ever seen them ripe. I tried picking a few of the largest ones, that seemed to have more of an amber-ish background color than pure red.
The park is many miles away, so it is unlikely I will make it back there to check again. Is it likely that the seeds are mature, even if the pod is not brown? Thanks!
