Can someone tell me how to propagate the new growth from this plant??
Propagating from Mexican Lily??
you may be able to find a sprout coming up on one side that you can try to dig out with some roots attached, and plant that. (I'm not personally familiar with it, and Plantfiles doesn't have any details)
The only way I have done this is by root division. I should think cuttings would root but have no experience...
