MegaCopa Blue spreads itself into a dense mat of tiny blue-violet flowers that hold steady through our humid season without flagging or getting leggy. Unlike smaller bacopa varieties, this one grows fuller and stronger, so you get better coverage in hanging baskets and window boxes with less fussing.

Moisture and part shade keep it happiest, though it tolerates full sun if the soil stays evenly damp. Pick one up in late winter or early spring to give it a head start before heat arrives.
