Aconite Seeds, Yellow
A cousin to the more familiar Blue Monkshood, this is not commonly seen in gardens. Plants form an upright clump of deeply-cut green leaves, bearing spikes of soft creamy-yellow flowers in mid-summer. May need staking in early summer. An outstanding cut flower. Plants prefer a site that will not dry out, away from thirsty tree roots. In hot summer areas this will need protection from afternoon sun. Easily divided every 3 to 4 years, in early spring. CAUTION: toxic if eaten/harmful via skin. The Monkshood plant reaches a height of 36 - 48 inches, and it generally is sturdy enough to not need staking.
medium yellow flowers (some forms of this species have bluish colored flowers) and finely-dissected foliage. The upright, leafy stems grow up to 3 feet tall, arising from a small tuberous rhizome. Blooms in late-mid summer to late summer. Not as easily grown asĀ Aconitum napellus, which it resembles, differing with yellow flowers and thinner more dissected foliage. Grow in full sun under cool summer conditions or part shade when warm. Best in well draining soils that never dry out.Ā
Zones (4)-8
GROWING
Monkshood seeds can be directly sown outdoors in late fall or early winter for germination the following spring. If you want to start indoors for a spring planting, Aconite seeds needs a cold treatment. Place flower seeds in water or moistened soil and freeze for three weeks. After the cold treatment, sow the Monkshood flower seeds in starter trays, and transplant seedlings into the garden when temperatures are warm.
