There is one species, nummularia, the creeping, little, yellow-flowered money vine, or moneywort, that besides being one of our best hardy rockwork plants is with us a standard so-called vine for baskets and vases. Its long, pendent growth is just what we want for that purpose. For cultivation see Glechoma.
Don't attempt to take it into the greenhouse in any shape in the fall, or it will get rusty and be useless. To thrive it must have its freeze-up during the few hard winter months.
