Delphinium exaltatum (Tall Larkspur) - 1 gal

Tall Larkspur

Spikes of large flowers that range from a light blue to purple appear from July to September. Bloom time can be extended by removing spent flowers. It is a host to 10 species of Lepidoptera. Perfect for woodland edges. Best in average to rich well drained soils but tolerates drought once established. It is not a fan of extreme heat and humidity so it will benefit from protection from harsh afternoon sun. Long stems can be floppy and may benefit from staking. This species of Larkspur is blooming after other native Larkspurs have gone dormant. Potentially threatened species in OH. Deer and rabbit resistant.
Plant Care & Installation Quick-Guide
Plant Care & Installation Quick-Guide

Proper acclimation and installation are key to your plant's success. Please cross-reference these tips with your plant's specific ID tags:

·       
Pre-Planting: Store plants in a light-appropriate area on soil or grass (avoid hot concrete or asphalt) and water daily until the soil is saturated and the pot feels heavy. If temperatures drop below 30°F, move pots to a garage or cover them to prevent root freeze.

·       
Installation: Dig a hole matching the depth of the pot, remove the fabric container, and ensure the plant’s crown or root flare is level with the ground. Fill gaps with soil, water heavily, and apply 2 inches of mulch—keeping it clear of the stem.

·       
Ongoing Care: Check moisture daily by feeling 1–2 inches into the soil; water deeply at the base if the soil feels dry or warm. Newly installed plants require frequent watering (up to 3–4 times weekly in heat) until fully established, which can take a few months for perennials and up to two years for trees.
