I have grown this plant for about 2yrs in N. Houston/Spring, TX area. I bought two small plants on eBay, lost one and one has gown and been divided several times. I absolutely love it! It is not only attractive, but delicious in salads, or just pinched while walking in the garden! I haven't cook it, but raw it has nice flavor and texture.

Mine gets leggy (it can be cut and easily rooted in water or soil), and was about to bloom last winter, but got too cold; as one other gardener mentioned, it can withstand light freezes and come back in the Spring. We have been having very mild winters here the last two years, but I think that when we have our normal freezing weather, I will definitely protect my parent plant and take cuttings just in case!

Just got this plant - looks great but haven't tried eating it yet.

"...that it will nearly always revert to the wild type with solid green leaves...and the green leafed type may contain toxic alkaloids..."

Can anyone point to an authoritative source for this information? I've seen this mentioned on random web pages, yet I haven't been able to find any apparently well-researched sites mentioning this reverting to a toxic form. I'm beginning to suspect this is a myth.

I have a question. I'd like to try to grow this plant indoors. I live in Minnesota (so NOTHING is growing here now), but I have a grow light and a humidifier. Has anyone had any success growing these indoors?

Thanks!

Does anyone know where I can get this plant in Australia? As it does not grow from seed I cannot get it from any other country, but need to obtain a plant or cuttings. I am very keen to try it after reading lots of positive things about it.

It grows very well here near Gainesville FL, especially in the shade where nothing else survives. It freezes back to the ground some winters but comes back in the spring. It is easy to add to just about any recipe in place of spinach but it turns all green when it is cooked so add it after cooking if you are looking for the purple color in the dish. Or garnish the dish with fresh cut leaves on the side.

This plant attracts butterflies and is a host plant to the Kamehameha butterfly.
It was introduced as a food plant from Africa to Australia, and then from Aust to NZ and the other Pacific islands.

The problem with reproducing this plant from seed is that it will nearly always revert to the wild type with solid green leaves...and the green leafed type may contain toxic alkaloids. The toxic green leafed form grows wild from wind-distributed seed in numerous Pacific islands such as Okinawa, Fiji, Samoa and Hawaii.

Losing the fancy purple coloration, and the safer food qualities that many gardeners desire, is very counterproductive.
So, this plant should be reproduced by cuttings if at all possible.

I have been growing this plant successfully for several years now.

The web site article mentioned in message above is NO LONGER AVAILABLE. It was excellent and I'm glad that I saved it. If you would like to read it, send me a D-Mail and I'll send it to you.

I certainly recommend this plant and the article.

Apparently, viable seed is not an option - the plant is normally propagated via cuttings.

I love this purple and green spinach and had some growing a few years back in our garden. We have since moved and we lost our plants. I have been looking for seeds ever since and have not been able to get them.

When I ask for Okinawan spinach here, they point to a plant that is sort of viny and the leaves are all one shade of green. It is said that eating a few leaves of this particular 'Okinawan' spinach on a daily basis will help lower cholesterol. I use this also in salads and inside tortilla wraps.

TO: Breezymeadow - A huge Mahalo! The address provided at the bottom of the article on the link you sent is just 4 miles up the road from where I live! I'm contacting them this morning to see if I can get cuttings.....Thanks, again!

Uptading:
I was able to get some cuttings and now have two fairly healthy plants. They are still sort of small, but I think they will make it.

Gynura crepiodes is a tropical, sup-tropical vegetable that makes a nice addition to salads. It can also be eaten when cooked. It is grown commercially as a vegetable in China. It is also an attractive pot plant--shiny green leaves above, purple underneath. Grows well in subtropical Florida. It is somewhat frost intolerant until established.
