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

'Indigo Spires' sage is a vigorous hybrid prized for its 12- to 15-inch-long, twisting spikes of dark violet flowers. It is a non-stop bloomer from early summer through fall. Blooming can be further encouraged by pinching stem tips early in the growing season and deadheading the spikes once they fade. 'Indigo Spires' quickly grows to 4 feet high, and can be grown as an annual where not hardy.

This cultivar of the eastern North American native Joe Pye weed is shorter and bushier than the species. From late summer into fall, its domes of dusky pink flowers attract butterflies and other insects. The seedheads persist well into winter. Grow 'Gateway' in a border, meadow, or cottage garden. It does best in soil that does not dry out.

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

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.
