Sorry, can't help you with plants, and not from Oregon.

But, you can get seeds from a lot of sources. A couple of really good ones are Seeds of India (seedsofindia.com) in New Jersey and Kitizawa Seed Company (kitizawaseed.com, I believe) in California.

They are fast and easy from seed, and start bearing in about 2 months.

Thanks denninmi for your reponse about plants and seed of bitter melon.
Actually there is no shortage of seeds here in the Salem area. I am in the process of working with them, though no success yet. Have not given up on seeds yet. Though in the mean time I thought I would try to look for plants as well. I don't have a great deal of time to work with for the season ahead.
Thanks again

PS. I also would welcome suppliers of plants from other areas of the country, if they can ship promptly and securely to us.
