Botanical Name: Salvia longispicata x farinacea‘Mystic Spires Blue’
General information:
Jimmy Turner, past Director of Horticulture Research at the Dallas Arboretum, says, “So, what is so special about ‘Mystic Spires Blue?’ It blooms constantly – all summer – with 10- to 12-inch spikes of deep blue flowers, and stays short enough to use in residential landscapes without staking.”
According to San Marcus Growers, mystic spires blue salvia is a “hybrid between two large Mexican sages — Salvia longispicata and S. farinacea and was discovered as a chance hybrid seedling at the Huntington Botanic Garden in the 1970’s. Salvia Mystic Spires Blue comes out of the Ball FloraPlant breeding program in Illinois.” It is great for perennial beds, mass plantings, and large containers. The large blue spikes are a great companion for Black-eyed Susan or New Gold Lantana.
