Auckland, New Zealand, zone 9b/10. Saw this plant groing in someone's yard and loved it. So planted a small one in the garden. It kind of just sat there over winter but once the weather warmed up it started to take off, and now I am thinking it's going to need a bit of control before too long to stop it taking over. Various websites say it only grows a foot tall, but it seems to be about double that, it's loving our climate.

I received this plant from my dad, he split his own. I am growing it inside because it rains way to much for this delicate baby here in western Washington. Out of all my plants it is my favorite. I enjoy the changing colors and have become emotionally attached. I am sad to hear that some dogs are allergic. I have a friend with two dogs asking for a start. thanks for the info! I'll pass it along.

I wondered why I hadn't seen this beautiful plant in Southern California gardens. Now I know. I bought three at a big box and planted them in an area that gets partial sun, even in the winter. I was careful not to water overhead, and kept them moist. They lasted for a while, but the minute we had a very light frost, they began to decline. The weather warmed up, and they continued to decline. Sunset listed them as being a tough plant, but that has not been my experience here in Pasadena (21 Sunset, 9a USDA). I think the soil in California may be too heavy, though this plant might be okay in beachside communities here. I don't know if they are dead to the roots yet. I'm leaving them in situ.

While I love this plant for its clumping ability, and thus it will cover a large area with time, I am severely allergic to the plant and have been advised to completely coverup when gardening.
Wherever the plant touched my skin a break out in a raised reddened area. Even more weird - I also get these red itchy patches where I haven't had direct contact, but only after direct contact. For example, today I purposely rubbed the plant on my forearm as a test and came out in a red rash at that spot, but also on my upper thigh.
I'm highly amused to read that dogs commonly are allergic to this plant.

I bought this plant for the purple color and pretty pink blossoms but did know much about it. Planted it in a large pot by the walkway and have enjoyed it. I have a dashund that has been to the vets several times over the past few months with sores from scratching on his stomach & back. The Dr. knows he has an allergy & asummed it was from the yard grass. He has been on steroids, antibiotics, creams, twice in 3 mos. He's fine in the front yard. After hundreds of dollars & reading this I do think I know now what his allergy is from. Thank you so much.

I am in the process of doing the job myself and taking out the rhizomes and as much of the roots as possible. It is very difficult to get all the little seedlings carpeting the ground.

I haven't had this one long enough to make any judgments as to how my experience is. I can see for reading the other comments it could be a problem. Since I have dogs and it can become invasive I will keep it in pots and see how it does. I may change my notes on this later.

I think this is a lovely houseplant here in Nebraska. I received it as a college graduation gift from my great-Aunt. It was originally my great-grandmother's. My only problem is that the shape has really changed since I've had it. It's gone from more compact and bushy to very spread out. Does anyone know of a way to prune it maybe to get it back to the compact fullness that is so pretty with the purple leaves?

We live in Kailua-Kona, HI and the plant does very well here. Unfortunately we have dogs and they have developed a terrible rash that only steriods help. As I post, we are removing the Oyster plants. Be safe and don't use these plants if you have dogs, the rash symptoms are terrible and causes pain to the dog as it scratces itself raw until they are bleeding.

I have been researching this plant. It grows in various locations on my property. I have allowed it to run free and it is spreading everywhere. . I find it quite attractive as a ground cover. It is almost totally weedfree and highly drought resistant. I am trying to water minimally and certain plants fit well into my scheme. Sorry if it's invasive, but I love this plant for my South Florida property.

For many years I thought that the oyster plant was a harmless plant that provided good ground cover along fences in Florida. Recently my dog, I discovered, has developed a horrible allergy to this plant. Her underside breaks out in a rash which is hard to control. After a week long regimen of benadryl and steroids the itchy rash subsides, but the steroids cause other complications (uncontrollable urinating and an increased appetite). And then if we are unlucky enough, she manages to get into the plants again while playing with the neighborhood squirrels.

I do not recommend this plant in any yard that has house pets that like to travel along the fence where the plant likes to grow. The plant has juices that can cause burning and itching to human skin as well.

I grow this as a houseplant up here in Indiana. When I put it outside for the summer, it really gets full and bushy and full of its little flowers. Mine is the purple variety, making a very nice accent wherever I put it. Surely growing it up here does not contribute to its invasive tendencies further south.

I see this plant far too often to find it pretty... It pops up everywhere here if there is another oyster plant nearby. There are pups completely covering the ground in some of my beds, whether it be in shade or in sun. If they had blooms like bromeliads, I might change my mind about the plant. :)
As it is, the white blooms are hardly noticeable, and now that I know it spreads by seeds I find them even less appealing! Please show sympathy for Floridians by taking some home with you after you've visited us.

I am in southern California (zone 8) for about 6 months and it didn't do well outside. It gets up to 115 here in the summers and the air is dry the majority of the time. The leaves burned or shriveled up even in the shade. The stems were starting to shrivel also. Zero growth even with reg watering. But after reading this forum, I moved it inside to the bathroom where it thrives in the humidity. I keep it on the bathroom sill where it gets very strong CA sun. Now it has grown significanly in only two weeks. It sprouts new leaves almost everyday! Green leaves slowly turn to a deep purple. The "spray" of the leaves reminds me of the Spider plant which I adore. Two plants have now sprouted into four. I read somewhere that they love to be rootbound so I won't disturb it for a long time.

I have to say I like this very attractive and "well groomed looking" plant, but can tell in the few seasons I've grown this species there is the distinct possibility it could become invasive as far north as extreme north Florida (8b-9a). Mine is well contained within concrete barriers and wooden fences, but it does quite fine here hard on the Georgia state line -- even in shady and damp conditions. It spreads nicely, but not aggressively in a fairly low light situation. I can only imagine what it might do in the hot, dry climate it apparently prefers. A couple of severe freezes (multiple nights in the low to mid 20's) here in N. Florida only knocked it down a bit --- it came roaring right back in the spring from the roots. Thanks to all who warned about it aggressive tendencies.

Boatlily, Moses-in-the-Cradle or Moses-in-the-Basket or Oyster Plant (Tradescantia spathacea) is highly invasive in the U.S. in disturbed areas, coastal strand, vacant lots, around old buildings as well as in very many natural habitats in central and southern Florida from zone 9a south along both coasts through the Keys, Bahamas, and parts of the Caribbean, where it also is invasive in some or many areas. It is fast-growing, propagates by underground roots and runners (also often by seed), and quickly invades and colonizes disturbed sites such as around old or abandoned buildings, in the cracks of sidewalks and concrete, and in vacant, weedy or undeveloped lots as well as very often in parks, nature preserves and natural habitats, crowding out other low native groundcovering vegetation and... read more

I got this plant from my husband's great aunt(she's 86)and together we have supplied the family with pieces of it. It's a wonderful potted plant around here. I've been afraid to plant it out in the ground myself for fear of losing it. The City of Anniston planted it last year in the median of one of the main throughfares and around the entrance of one of the city buildings. I couldn't believe they came up with this plant when usually it was some other everyday plant for this area. I wanted to go and ask for them during the fall because they dug them up and I haven't seen them since. So who knows where they are now. I put one of the plants in the house every winter and the rest of mine are in the greenhouse. They are such a pretty plant to have indoors during the dead of winter.

This is one tough plant! In St. Petersburg, Florida you can often find it growing at abandoned or boarded up businesses, like an old service station for sale, or a building waiting to be torn down, where the plants can live for years surrounded by concrete, just on rainwater.

In a regular garden it makes a very attrractive and colorful groundcover for a sunny spot, which can be a difficult situation in such a hot climate. I didn't realize that it would grow up here in Northcentral Florida, zone 8b, so I am going to give this old favorite of mine a try, probably as a groundcover under white crepe myrtles, along with some blue agave, out by my gate to the dirt road--probably the most difficult situation on my property, because it gets hot noon-day sun, and car fumes and whit... read more

Loosely translated, Sanchezia says that in Mexico, the plant is used to cure wounds or infections; the juice from the leaves are used to disinfect.

Yes the plant can become invasive, however, it really is pretty and quite hardy! Here in Northern Florida, we get a few hard freezes but the plant comes back in the spring.

I live near the coast of SW Florida. After planting quite a few Oyster Plants outside my home I discovered, via The Native Plant Society, that this plant is highly invasive in Florida, propagating by spreading and by air-carried seed to places far from the original plant. As it spreads it covers the ground thickly and prevents other tree and native plant shoots from coming up. If you live in FL please take this seriously.

I recvd a small portion of this plant from a nearly dead mother plant which was left for several weeks in a home w/ no water. Very hardy plant as we still found green on this otherwise dried out husk. Not knowing at the time what type of plant it was, I placed this small green leaf in water to root. This plant took off, rooting after a week or so, and continues to be a welcome addition to our home nearly two years later. Seeds may be harvested by plucking the pods and allowing them to completely dry out. Seeds sown in soil will begin new plants. You may also propogate by allowing leaf cuttings to root. Very hearty and easy to grow!

Stems to 8in high. Leaf tufts frow to 6-12in. wide, with a dozen or so broad, sword-shaped, rather erect leaves that are dark green above and deep purple underneath. Flowers are interesting rather than beautiful; the small, white, three-petaled blooms are crowded into boat-shaped bracts borne down among leaves. Selection 'Variegata' has leaves stiped red and yellowish green.

Avoid overwatering; try to keep water out of leaf axils. Tough plant that takes high or low light intensity, casual watering, low humidity, and heat. Plant most often grown in pots or in hanging baskets; grown as ground cover and edging in Florida.
