My Indian Pink has been replaced by Buckthorn
2 years ago, I planted an Indian Pink (Spigelia marilandica). The year after, it returned so I planted a second one. My hope was that they will form a nice clump.
This year when both came up again, I planted a bunch of new ones around it. Afterwards, I notice the leaves on the new plants look slighly different than the old ones. In fact, the old ones look more like Buckthorn. Has the villainous buckthorn (who I am constantly pulling out of the yard) killed my Indian pink and took their place :-).
I suppose I can let it sit for a few months and see if flowers develops.
