Salvia longispicata x farinacea 'Mystic Spires'  PP#PP 18,054

Mystic Spires Salvia is a compact, long-blooming perennial with deep blue-violet flower spikes that attract butterflies, bees, and hummingbirds throughout the warm season. A dwarf selection of the popular 'Indigo Spires', this salvia maintains a tidier, more upright habit while still offering the same continuous flowering from spring through fall. It’s a reliable choice for borders, pollinator gardens, containers, or mass plantings, especially where space is limited but vibrant color is needed.


Mystic Spires thrives in full sun and is highly tolerant of heat, humidity, and drought once established. It performs best in well-drained soil and can tolerate both acidic and alkaline conditions, making it a versatile fit for most Texas landscapes. Its aromatic foliage is deer-resistant, and it rarely suffers from pests or diseases. The plant typically grows to 18–30 inches tall and wide, making it useful for front to mid-bed placements. For massing, space plants 18 to 24 inches apart.


In USDA Zones 7–10, Mystic Spires is cold-hardy and often returns in spring even after frost dieback. In colder areas, mulch around the base before a hard freeze to protect the crown. Prune back by one-third in early spring to encourage bushy growth and more flower spikes.
