It depends on the species, I guess. I've experienced significant difficulty in eliminating Wandering Jew. Some say only to plant Heep's Spiderwort in containers, but I have planted it in a dry flower bed below the eaves of the house. These succulents certainly are hardy, so I'd probably play it safe and remove it from the pot, especially if you don't know what species it is.

Jim, I have two varieties.......one is the blue one that grows in the wild, and it spreads, but is easily pulled up. The other one I have is purple (bought it, but have long since lost the tag) and it, too, spreads and seemingly throws seeds as I find it in strange places. They are easily pulled when young, but I would be careful about the placement in the bed.

I've never had an issue with mine. once the clumps get large enough, I divide and spread around. I've only ever planted it in dappled shade though.

I bought a purple one from Lowes bargin bin, and planted it in 2009. Last year, my neighbor next door had at least 10 plants growing in his grass. I went over there dug them up and brought them home. I just love them. Barbra

Thanks for your responses. I think I'll keep some in a pot for awhile before I decide to plant it in a bed.

I have the Widow's Tears, Blue Spiderwort Commelina coelestis that come up in some of my beds as volunteers. If I want them, I leave them, and if not, I pull them up. They are fairly easy to control. And they are pretty and bees like them!

Thanks Linda, I think that is probably the one I have. This year, the bees like everything. I don't think I've ever seen the like. All summer long, it's been honey bees, bumble bees, carpenter bees, and little native bees on everything that's blooming. There hasn't been a day that the coral vine wasn't completely covered up with honey bees.

One of my rural friends has a vacant area near her house that is (was) covered with spiderworts. There were blues, purples and a few pinks. I dug all colors, but only the blue is still thriving in my bed.

Notice that I said "was" because I do not know if any survived this severe drought. She did not plant them.
She did not even notice them until I pointed them out to her a few years ago.
