I am in zone 6b, and the Acanthus Mollis I have just absolutely sulks in the summertime even with only half sun location and me watering it every other day. it just hates the hot/humid conditions I guess. I am planning on removing it.... which I know is a chore since every bit of root will regrow.

My father grows Acanthis Spinosus... it it on the other hand loves the local conditions

i will never be able to get rid of mine. It has taken over an area with Azaelas and Daphne so it is impossible to eliminate without disturbing those roots. I rue the day I planted it. It was given to me many years ago by my mother-in-law. Hers was bordered on one side by a cement walkway and on the other side by the cement foundation on a stairway to the front door. It was lovely there and contained in it’s cement prison.

i always love hearing about the trials and tribulations of growing the same plant

in different parts of the country.
