you have just reminded me of when i used to go walking in some woodland near here and was mezmerised by the spindle trees i saw there, i walked past them and touched them every time i passed that way, daily in facvt when taking the dog for a walk, i saved some of the seeds and tried in vain to propagate them this spring, maybe the seeds were too old, i maust go there this weekend to see them again and perhaps collect some fresh seed, only a few. would they be best put in soil at this time of year to over winter?
