Salvia Blue Monday quickly grows up to 28 inches tall and about 12 inches wide. The brilliant purple-blue flowers last well as cut flowers or dried flowers. The plant prefers loose soil, good drainage, moderate water, and mostly sunny locations.
How To Grow Salvia From Seeds
For earlier blooms, sow Salvia flower seeds indoors 10 weeks before last frost. Sow Salvia flower seed in starter trays and press the seed into the soil. Salvia flower seed needs light to germinate. When the frost season has passed, transplant Salvia seedlings into the garden 12 - 18 inches apart in a sunny location. Or, sow Salvia flower seeds outdoors in spring after frost danger has passed and prepare soil by weeding it and loosening it.
Lightly rake the flower seeds into the soil and keep the seeds and young Salvia seedlings moist until well-established. Provide plenty of water in dry weather. Salvia plants grow best when provided moist, but well-drained soil in full sun to partial shade. Salvia Flower Care: Remove the spent flower spikes to promote continued blooming. If the Salvia Horminum plants begin to look tired in mid-summer, trim them back by 1/3, and they will be re-energized and reward you with more blooming.
