I bought this plant in Big Pine Key and left it when we moved (should of never done that!!!) It has taken me 8 years to find someone who sells the plant. I bought seeds but the plant I got isn't what is pictured and what I wanted. Then I found this place:

I love this vine. I snipped a piece off one growing in the garden where my husband and I were married a couple years ago. I put the snip in a pot and it grew slowly until a wicked frost killed it. There was a seed on the stem so I plucked it off, pushed it in the pot and forgot about it. A few months after mama plant died the seed started growing! At first was a slow grower, taking a few months to grow just a couple feet. Today, about five months after transplanting from pot to under an oak tree, it has wound its way up to the top and trying to reach for the tree next door. No flowers yet, but based on what I've read it should be blooming next year. I can't wait. :)

Challenging to grow indoors, but it is possible. I grew this when I lived in Guam, and it was a fantastic and easy to grow plant in that environment.

The seeds of this plant contain the highest concentrations of LSA of any plant out there. If you're thinking about trying to purchase some of these seeds for recreational purposes, I would NOT recommend it. Just because a drug is obtained from an organic source, doesn't mean that it's safe. You can loose your mind FOREVER, or DIE if you abuse this plant.

I don't think it does actually bloom the first season, although I can't remember where I read that. I know it needs a lot of rootspace to flower, also.

I know only one plant of this species growing here in Rio de Janeiro. It looks great, with contrasting green/silver leaves, veined leaves. The flowers are a plus, but not really the main feature to me.

The cylindrical root oozes active latex when cut. In Ayurvedic (Hindu) medicine, the plant is deemed a valuable general antiseptic. The leaves are used in native medicine as poultices, &c. The roots and seeds of have been used as a support of the nervous system, a geriatric tonic and mild aphrodisiac (probably due to the lysergic acid). The whole plant is reported to have purifying properties. It is also taken to help maintain healthy joints.

Arygeria nervosa, from India, grows to over 25 feet. The foot-wide dark green leaves are white underneath. The floweeers look much like other impomoea species. The vine is beautiful to grow just for the leaves --look very tropical.
