This native of the American Southwest and Mexico forms an evergreen shrub or shrubby perennial with dark, glossy leaves that are small (but slightly larger than most microphyllas) and softly toothed. It blooms off and on all summer, and again, more vigorously, in late summer and autumn, in blossoms of cherry-red. Its attractive foliage cloaks the plant to the ground, so it is well suited to the front of the border. It can grow to 4 feet tall and twice as wide.

(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This pest-free perennial blooms best during warm months. It is strange how these small blue flowers attract butterflies more than large-blooming, showy neighbors. Blue porter weed gradually reseeds nearby for a fresh batch of new plants. Mix with other species of Stachytarpheta for a variety of leaf shapes and colors ranging from purple to coral.

Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

(Eastern gamagrass)
Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

In early summer, slender stems are topped with flowers that produce a crop of jointed seeds. Clumps get large and die out in the center, so division is necessary. Autumn frosts turn the leaves attractive shades of red-bronze. -Scott Vogt, Native grasses, Fine Gardening issue #124

(Canary creeper)

Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This annual or perennial climber grows vigorously, yet does not strangle its host. Its edible leaves are deeply divided like the fingers of a hand, and its bright yellow flowers are outrageously formed: The larger, upper petals are deeply fringed and look like tiny birds' wings; the smaller, lower petals are spurred. It blooms in summer and autumn and can climb up to 12 feet.
