Herniaria ‘Sea Foam’…aka variegated rupturewort is a plant I’ve long adored, but one that hadn’t exactly thrived for me in the ground.  Well, this spring, I tried on a compost rich, evenly moist bed in full sun for a half day and bingo…it has excelled there.  This delightful dwarf groundcover has tiny leaves, each with a narrow golden border.  Here’s a photo of it as we go into fall.
