Height 4 ft

This variety of Rocket Larkspur is also known as both Delphinium and Larkspur; this variety has tall slender spikes that are densely packed with delicate florets in beautiful shades of soft purples. Lilac Spire is fantastic choice for cut flower gardens, borders and cottage gardens...even meadows for a great soft colour contrast. Blooms from early to late summer, and is a low maintenance ( if blooms become top heavy or topple due to heavy rains - may require staking) variety that is a quick grower, and provides copious amounts of seeds. Deer resistant and attracts hummingbirds, butterflies, and bees.

Because it’s an annual and matures in just 77 to 84 days, the best way to propagate larkspur is from seed. Whether you’re planning to sow seeds indoors or outdoors, you’ll need to cold stratify them for the best shot at germination; in cold climates, this happens naturally as the plant drops its seeds in the fall, and rain or snow produce the stratification process naturally and the seeds germinate. 

  • Sun to part shade
  • Well draining soil
  • Outdoor sowing: scatter seeds 2 weeks after your last frost in a spot that receives 6 to 8 hours of sun per day. Plant 1/2 in deep 
  • Spacing: 12 in
  • OR start seeds indoors 4 to 6 weeks before the average last frost date in your area.
     Using biodegradable pots because plants develop long taproots and prefer not to be disturbed when transplanted. Fill each pot with potting mix. Place 2 seeds inside each pot and cover with just 1/4 inch of soil.
     Use a spray bottle and lightly water the newly planted seeds; keep the soil moist until germination ( 2 weeks). When the plants have 2 to 3 sets of true leaves, thin to one plant per pot. Place pots outdoors 2 weeks after the last frost before you transplant them out to the garden. To transplant, dig a hole in a location that receives 6 to 8 hours of sun and set the biodegradable pot inside the dug hole. Backfill with soil and water thoroughly.
  • Note: to promote multiple blooms on one plant, after the first flower is spent, make sure to cut the plants back (almost to the ground). 
  • Seed Count: 30
