Tree collards rarely set seed. The current seeds I am selling were harvested July 2017. I am making them available for plant breeding enthusiasts and international customers. Each packet contains approximately 30 seeds. I had over 95% germination rate when I tested them in 2017.
Unlike tomatoes, tree collard seeds are not known to come true to type. Other brassicas were in bloom at the same time as these plants were flowering. I have no idea what these seeds will produce. I have heard reports of people getting tree collard like plants from tree collard seeds. You may get an amazing new variety of tree collard. Or you may get plants that look like tree collards but go to seed more often. Or you may well get something that is nearly identical to the tree collards which these seeds came from. It is a roll of the genetic dice.
For residents of the U.S. interested in growing tree collards I highly recommend that you purchase cuttings or live plants from me. Plants grown from cuttings will be genetically identical to their mother plant. The variety of purple tree collards I grow here in Berkeley is superior to any other perennial kale or collard green I have come across thus far. However, for international customers who can’t get live plant material shipped to them (I do not ship any live plants/cuttings to foreign addresses) this may be your best bet. These are also recommended for plant breeders in both the US and abroad experimenting with new varieties of brassicas.
Unfortunately I cannot guarantee delivery for international orders. Please do your research beforehand to see if customs is likely to confiscate your items. I will carefully package and label your order with a proper botanical name and customs declaration. I cannot provide phytosanitary certificates. I have successfully shipped to Australia, parts of Asia, parts of Africa, both in a first class package ($20) and in a regular letter envelope ($10). The regular envelope took about two weeks longer to arrive. Shipments of seeds to the UK and Denmark in regular envelopes ($10) arrived in about a week.
If you are in a country not listed as a shipping option and wish to purchase seed please contact me and I will get it set up for you so that you can order.
