What you need to know to Plant & Grow
Larkspur possesses a delicate taproot system that resents transplanting, making direct outdoor sowing essential for establishing strong, healthy plants.
-
Direct Sowing (Required): Direct sow seeds outdoors in late April or early May into a sunny site. In mild Canadian zones (Zones 5 & 6), mid-to-late April sowing yields superior results.
-
Sowing Depth & Spacing: Sow seeds 3 mm deep in well-prepared, moist soil. Keep the seedbed consistently moist during the 14-day germination period.
-
Thinning & Protection: Thin emerging seedlings to 20 cm apart once established. Protect tender young seedlings from spring environmental extremes such as heavy downpours or unexpected sharp frosts.
-
Botanical Note: Unlike perennial Delphinium species that form dense, single floral spikes, Consolida is an annual species featuring open, branched stems with shatter-resistant florets that hold up exceptionally well in rain and cut-flower vases.
