Stachys byzantina
'silver carpet' can give your perennial garden that soft almost white
contrasting plant that sets off all the rest. Some folks cut off all
the flower spikes as they come up. I generally give them a chance to
flower and then go purge them all, as the flowers are nice enough in their
own right. Stachys byzantina foliage grows 6-8" tall, flowers
to 18" and slowly spreads a few inches each year so long as there is
water available. I get some recruitment of new seedlings.
Plants are Winter hardy to most anything California can dish out.
