    Great info Randy, thanks! Maybe ill pick up some D. Mexicana and D. sylvatica seeds to experiment. I definitely dont have room for a ton of plants, but Id be interested in germinating them, taking the strongest ones, and selling the other seedlings.

    Do you think a very bright north window would suffice for this genus since they like shade? It gets strong evening sun and good light all day.

    I don't have enough light from windows to grow anything inside with natural light, so I started seedlings under lights. I'm in the process of moving pretty much all of these into individual pots (if not already) and outside. I don't have full sun anywhere outside. They still seem to go dormant inside at the appropriate time, even when grown under lights that are on 24/7. I don't know how they figure that out. My D. mexicana has been outside since I got it.

    However, I'm pretty sure people grow these inside in sunny windows, and they grow well. I don't know how much in terms of less sunny windows they can take. I'm pretty sure Bihrmann used to grow all of his plants in windows. He has photos of his D.mexicana in a window, but I can't tell how much sun.

    For D. elephantipes he says for sun: "Medium-Maximum".

    Here are some photos of D. mexicana seedlings: close to 100% germination, in a couple weeks. The second batch of seedlings:



    Once they started to vine I transplanted them. Here are some of the seedlings (unfortunately the photo is fairly low resolution):

    Great info page, and they sell specimens as well, but they are out of stock. I emailed them a few weeks back and they said to check in mid summer.
    You might check with Mesa Gardens: http://www.mesagarden.com/o2015.html

    I just went through and (finally) gave the small number of my plants (Dioscorea sylvatica) that still needed them their own pots. I also moved everything outside. My current count is 25 plants, of which about 10 have emerged from dormancy. This is after giving away and selling a lot of plants. As far as I'm aware, my only losses were a couple tiny pots with 3 each of the smallest plants in them. I assume the death of a dormant plant, especially if the soil is at all moist, would lead to a rotten tuber/caudex. I'll know for sure which are the survivors after they all emerge from dormancy. Dormancy doesn't seem particularly synchronized in these plants.

    An additional note: there are reports that Dioscorea mexicana but not D. elephantipes can be propagated from cuttings (and still grow a caudex, presumably). I tried last year with D. mexicana, and although some of the cuttings remained alive for a while, none rooted. Otherwise the plants need to be grown from seed, and as far as I'm aware the species mentioned here are all dioecious. So both a male and female plant is necessary.

    I have a different kind of Dioscorea that vines- it commonly goes by "potato vine" here in the South, is a type of yam, and is considered an invasive species in Florida. Here in Texas, however, it dies back to the tuber during winter, so we do not have the problems with it overtaking brush like Florida does. I love it, it grows very fast and is useful in covering ugly trees and fence lines and such.

    Oh yeah, we call it air potato, that thing is horrid, every time you remove it, it comes back from the tubers you missed, took three years to get rid of here

    I have one that I bought from seed seller J.L. Hudson as Dioscorea batatas. It's edible, and I believe it's the same as one of the large (up to 3 ft.) elongated tubers found in a lot of markets in California. I don't remember what the name is in markets, but one common name is "Chinese Yam", also "Cinnamon Vine" due to the scent of its flowers. It's not supposed to be invasive here. I think the one that is the more common invasive East of the Rockies is Dioscorea bulbifera. Whether thiese are truly different, and whether everything is correctly named, I don't know.

    They had 1 gallon pots of it for sale last week at the wonderful plant sale at Cabrillo College.

    Here's an invasive plant description. It looks like it's also invasive in WA and OR, west of the Rockies:
