Larkspur Plant Profile
Larkspur (Consolida
ajacis) is an annual flower with tall bloom spikes in late spring and early
summer. The flowers are typically blue, purple, pink, or white.
It is native to the Mediterranean region and can be grown in
zones 2 to 11 as an early season annual.
It grows best in full sun in well-draining soils.
You can direct sow it in early spring or in late fall in
zones 6 to 8 for blooming the next spring. You can also starts seeds indoors in
late winter under grow lights. Larkspur seeds need cool temperatures (below 55
degrees) in order to germinate.
It prefers cool weather and does not tolerate heat. Young
larkspur plants tolerate frost well.
Because Larkspur can grow to 3 to 4 feet tall, you may need
to stake it especially in locations with strong winds.
Larkspur is a terrific cut flower. Cut the stalks when the bottom two to four
flowers have opened. The flowers will continue to open in the vase. You can
also let them dry on the plant for dried flower arrangements.
After flowering, you can collect seedpods for planting next
year or let them go to seed to self-sow themselves.
Larkspur is deer-resistant as it contains toxic alkaloids. It
is visited by various pollinators including bumblebees and butterflies.
