Description

Hubricht's bluestar is a neat, clumping perennial that can form a mound 3' tall and that large around. The elongated leaves are needle-like and light-green growing on smooth, erect stems. In spring, the plants display a profusion of delicate, pale blue to lavender star-shaped flowers in terminal clusters. The foliage becomes spectacular in fall when it turns golden-yellow.

Cultivation

Low maintenance and easy to grow in average soil, established plants are tolerant of dry conditions and rarely require additional watering. Plant in full sun for the best flower display and fall colors. Flowers will last longer with some shade, but the stems can become leggy and require pruning to remain erect. Its delicate and feathery appearance provides a nice textural contrast in the perennial garden, particularly when massed. Its tolerance of dry conditions, also makes it an excellent choice for a rock garden, where its compact size and airiness will not compete with other specimens. Zones 6-8.

Propagation

May be propagated by division of mature clumps in early spring. Fresh seeds will germinate immediately after sowing. Stored seeds will remain viable for several years but will require soaking and nicking to improve germination. Plants propagated from seeds will flower the second year after germination.

Additional Notes

Though the native range of Amsonia hubrichtii is very limited, the species is becoming very popular in cultivation, and for good reason.
