If you have a rock garden or a small space that you can observe from up close, then you need a hardy herbertia. This easy-to-grow and most amazing iris relative hails from a large region from Florida west to Texas and south to Uruguay. Herbertia lahue forms a miniature clump of narrow foliage to only 2" tall. The plants are topped for us from early-to-mid May with exquisite, dark blue-lavender flowers. Each flower is composed of three large, oblong petals surrounding a contrasting white eye etched in blue...simply marvelous! For those in the arctic zones north of Zone 7, plant your herbertia in a container garden or trough. Since they go summer dormant soon after flowerings, they require little to no care through the summer months.
