Another Z. garrettii cultivar, 'Mountain Flame' has the same brilliant orange to scarlet trumpets mid-to-late summer, and dense, light green leaves. It is taller than 'Orange Carpet,' growing about 18 inches tall and 18 to 24 inches wide. It blooms earlier than Z. arizonica. A wonderful addition to the perennial border, or along the edge of a sunny shrub or foundation border. Attracts hummingbirds.
Grow in full sun and well drained soil, otherwise, not particular. A little mid-day shade will keep it from looking parched. Cut back in late winter to early spring. Once it's established, water just a couple times a month. Attractive to hummingbirds. It has a slightly cascading habit, so planting on a wall or at a curb can create a pleasing effect.
