I have three plants that I do not intentionally let out of their pots.
All three have a reputation for going rogue if let loose.
I LOVE all three or I would never chance a release of a new “Kudzu” into my gardens.
I have not had the least bit of trouble with this first one,
Bleeding Heart vine/ Clerodendrum speciosum, thomsonia.
I have taken cuttings and produced new plants, but it has never escaped on its own.
The second one is also a vine.
Love-in-a- Puff/ Cardiospermum halicacabum produces puffy pods which contain round black seeds with a white heart on each.
After three years of having this plant, I have only found two escapees near to where the mama plant was the previous summer.
The last one however, Jewels of Opar/Talinum paniculatum has escaped many times.
I always dig up the seedlings and transplant them into pots.
This plant has a long root that may prove impossible to remove.
The beauty of its blooms and pods is what I find irresistible.
The “limon” leaves are edible, but I have yet to eat one.
(My husband has still not forgiven me for bringing some Crownvetch on the property nearly thirty years ago. We are still finding it.)
So these three are for pots, but worth the risk.
