Larkspurleaf Monkshood

Colombian Monkshood should be watered regularly, 2-3 times per week, in order to keep the soil moist but not soggy. Water the plant until the soil is saturated and allow the top 1-2 inches of soil to dry out between waterings. Avoid overwatering, as this can lead to root rot. Generally, Monkshood plants do not require a lot of water, but they may need more during periods of high heat and drought. This water-wise plant is also quite tolerant of dry soil, but be sure to give it extra water if the soil is dry or if the foliage starts to wilt.

Columbian Monkshood needs fairly consistent exposure to direct sunlight throughout the year in order to thrive. During the summer months, it requires at least 4 to 6 hours of full sun in order to promote strong, robust growth. It is best to give the plant some shade from the midday heat during the hottest parts of the summer. During the winter months, Columbian Monkshood should still receive some direct sunlight, but approximately 3 to 4 hours per day is ideal. Direct sunlight can still provide some warmth and additional growing opportunity in winter. Too much shade for extended periods of time can lead to weak, leggy growth.

Columbian Monkshood should be pruned in late winter or early spring. Generally, it's best to prune the plant down to about 12 inches above the ground each year. This will help keep the plant under control and promote more floral growth on the remaining stems. Cut off old flowers as they fade, along with any dead or damaged foliage. Pruning hard in the spring will help increase air circulation and light penetration, which can help prevent some fungal diseases.
