Great Design Plant: Plumbago
A multifacted ground cover with an enormous range, plumbago solves landscape problems with panache
Off the top of your head, how many exciting plants can you think of that grow just as well in Boston, Atlanta, St. Louis, Santa Fe and Seattle? There are a few, but this one is a star. Meet plumbago (Ceratostigma plumbaginoides), a ground cover that may just be your new best friend.
Plumbago blooms in flowers of the clearest cerulean blue, from midsummer into fall, finally segueing into winter with some outstanding red-to-purple foliage — yes, this is a ground cover with fall color, and while it's still in bloom. It's great for containers too.

This "little plant that could" grows just fine in all kinds of soils as long as they're not soggy. It handles drought with aplomb as long as it gets a little shade in the hottest part of the day; it's happy in light shade all day too. It coats the ground with its luscious, lightly glossy foliage, which emerges in late spring. Deer don't like it, and it can even take those tricky coastal climates.

Plumbago may be a bit tender in the northern reaches of its range, but since it dies back in the winter, it's what you could call self-mulching. Add a bit of additional mulch after it dies back and don't cut it back until early spring, before new growth pops up, and it should do just fine in zone 5. It makes good bedfellows with spring bulbs because it wakes up on the later side, and with taller perennials as well.
I remember walking into a nursery when I was a kid and seeing several untouched flats of plumbago, growing and blooming up a storm. Why untouched? Simply because no one knew what it was. Get to know this ground cover and don't make the same mistake.
