Purple flowers bloom in Nov & is 6' W x 5' T

Wish I had a better pic, was lucky enough to find this one. Had it in the front yard and I think I pruned it too soon, it died. Would love to replace it.

The purple flowers at the end of long stems bloom in Nov/Dec and the plant is 6'-7' wide & 4'-5' tall in the center. Humming birds, butterflies, and bees love it.

Thanks a bunch,
Selvan

 

Looks like Lavender to me.... Can you take a closeup of the flowers and foliage?

 

Notice: the plant have died.

 

Salvia leucantha?

 

David in L A, thanks so much...:)

With the plant IDed, I have made a couple notes:

1. Remove flower clusters as they age to reduce the weight on the stems.
2. Prune back in early summer to promote a bushier habit and to keep it from getting so top heavy that stems break off.
