Festuca glauca 'Boulder Blue' Festuca glauca 'Boulder Blue'
(Blue fescue, Gray fescue) (1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Regarded by some as the bluest blue fescue, this plant forms compact, cascading mounds of foot-tall, intensely blue, narrow leaves that are attractive in all seasons. Blooms are generally secondary to the foliage, but this cultivar blooms more heavily than most, with spikelets in summer. This cultivar is long-lived and very hardy. Grow in groups in a border or rock garden, or as a groundcover.

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

This small tree boasts an upright, spreading form and finely dissected gray-green foliage. Its spiky lilac-blue flowers appear from June through September; bloom can be prolonged by deadheading. Chaste tree can grow to 20 feet in southern climates, but in colder areas only 8 to 10 feet.
Vitex agnus-castus var. latifolia Vitex agnus-castus var. latifolia
(Chaste tree) (2 user reviews)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Chaste tree is a southern favorite beginning to gain favor across the country. Whether left to grow as a large, multistemmed shrub or cut back annually for a more compact look, this selection is a winner. Fine, lacy leaves are glossy and green. Bright blue flower panicles begin to form in early summer and continue through the heat of the season and into fall. This is a reasonably cold-hardy, deer-resistant woody plant, and while V. agnus-castus is typically considered a Zone 7 plant, the variety latifolia can be grown in Zone 6 and even in southern areas of Zone 5.
