I have two large Sephanotis plants on a trellis doing very well. For the past two years they have produced about 6 seed pods and presently there are 4 more seed pods. I have searched other websites and cannot find out what to do with seed pods and how to get them to grow. I have tried letting them dry and planting the entire pod and I have tired opening them up and planting the seeds but nothing seems to grow. Help! Does anyone know what I need to do with these seed pods? Thanks!
