Aloha Norris! E komo mai to the GTS community!
I am also relatively new here, and have not yet come across others from Hawaii, although I have been sharing about this space in other social media channels, including the Small Farm Hawaii SFH facebook group, where I am an admin, and also on the Homesteadn Hawaii group, where there are many people involved with seed saving, sharing, and selling. Are you on Facebook?
La’akea holds a special place in my heart because it is where I got my PDC. If there is any place to find mold resistant pigeon peas I would imagine that this would be a great place to inquire.
How long you been in Puna?
There are a lot of people coming to mind that you could reach out to throughout the island. One of the closest to you is Wade Bauer, who does edible landscape design. Between him and La’akea community you should be able to find locally adapted seed, or at the least get some leads on where to find it.
You can also check in with Amber Alohilani Woolsey and her partner Alva. They are in Kea’au, and have an excellent collection of plants. Alva makes a living in syntropic agroforestry work. They also support themselves and their kids by selling fruits, plants, and seeds.
Up Hamakua side the names that come to mind are Ginger John (Korean Natural Farmer, and owner of Sweet Cane Cafe), Narayan Higgins (Krishna Cow Sanctuary), Coconut Chris (Christopher Carter), and Spencer Willis who practices Syntropic Agroforestry.
Ginger John uses pigeon pea as a cover crop in preparation for planting his fields of turmeric. He grows a lot of it. Narayan very likely has some and is often willing to share plant materials. Coco Chris is an exceptional plant steward, and tends to have collections of some of the rarest plants. When I was working with him is when I took the photos of the very pretty ornamental pigeon peas posted above. Spencer works with a few “farms” I think, and surely has pigeon pea.
There are other names that come to mind too, but I think this should help you get started. If for some reason you still need more connections then don’t hesitate to reach out.
if your on facebook, make a post in the SFH group with a similar inquiry! It could be a great way to help spread the word about GTS in Hawaii, and get more of the community into this network, too. If the people I mentioned above got involved in what is happening here, then I think the Hawaii food growing community would find itself on track to solving a lot of wicked problems associated with farming in Hawaii.
