Sorry, no big deal, the secret.............I have always had my plant in a pot and so Sandy followed suit. This last Spring she decided to put Culebra in the ground and with morning sun, dappled shade starting at 11 am for the rest of the day. And it loved it!!
She is so tickled that Culebra has done so well for her.
I never put my Culebra in the ground or hardly disturbed it in the pot as I was told it did not like it's roots disturbed. Looks like that advice is wrong. Mine is going in ground next year!
