I'll break these down into different posts for (1) Ebay (2) Online and (3) Retail. Of course there will be overlap.

Where possible, the names of the plant(s) purchased might be useful. If you have any experiences as to whether their plants are correctly ID'd that's a big concern, so please mention it.

I buy most things locally, so this will be long and detailed for me. I'll just list a few places I buy at and fill in the blanks later.

Strybing Arboretum (San Francisco Botanical Garden, Golden Gate Park). Monthly sales.

UC Botanical Garden--Berkeley

I've bought nice plants at the following and recommend them, but don't expect to find variety. At times they may have no or very little Passiflora.

Annie's Annuals (Richmond)

Yamagami's Nursery (Cupertino)

other good sources that I haven't bought from:

Roger Reynold's Nursery (Menlo Park)
Berkeley Horticultural Nursery

I've occassionally seen nice plants at Home Depot.

I'll give details later.

Strybing Arboretum is the best place I know of in the bay area to find interesting Passiflora. They have a huge Spring sale, which I've never been to. However the regular monthly sales are pretty amazing. Among the plants I've bought--no doubt I'm forgetting a few: P. gritensis, P. parritae, P. loefgrenii, P. x exoniensis, P. exoniensis x parritae, P. parritae x antioquiensis ('Mission Dolores'), P. manicata. Also, the people working at the sale are true experts on Passiflora--some of the best. It's not to be missed. Oh, most plants are $15 for a 1 gallon, many in bloom or bud. P. parritae and P. gritensis were the most at $18.

I bought P. membranacea at UC Botanical Garden, $18 for 1 gallon. A friend bought P. pinnatistipula. Their plant shop is open every day the Garden is open, although they may not have as much variety. Their Spring/Fall sales have more variety, things such as P. parritae.

Annies Annuals: Often the only thing they have is P. sanguinolenta. I also bought P. 'Blue Horizon'. Last I was there they were selling P. loefgrenii x caerulea (possibly the reverse)and 'Constance Eliot' as well. Some of their more "choice" plants: P. exoniensis and P. membranacea are only available mail order for short periods of time. Prices vary and are cheaper at the nursery.
