"Mertensia paniculata is a PERENNIAL growing to 0.8 m (2ft 7in) by 0.6 m (2ft)."
"It is hardy to zone (UK) 4. It is in flower in July. The flowers are hermaphrodite (have both male and female organs)"
"Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and prefers well-drained soil. Suitable pH: acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It prefers moist or wet soil." [PFAF]

Edible Uses


"Easily grown in an ordinary garden soil with some shade[1, 111]. Prefers a deep moist but well-drained humus-rich soil in sun or semi-shade[200]. If the plant is cut down after flowering, it will normally produce another flush of flowers[233]. A very ornamental plant[233], it grows well in open woodland[200]." [PFAF]

Aphid host plant to Brachycaudus helichrysi & Macrosiphum niwanistum [Blackman AWHPS]


"Seed - best sown in a cold frame as soon as it is ripe[1, 200]. Sow stored seed as early in the year as possible. Protect from direct sunlight[200]. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Division, with care, in early spring or autumn[200]." [PFAF]

Medicinal Use


Mertensia virginica - Virginia Bluebell
"After bloom, the leaves yellow and disappear, and the stem collapse, so finding the seeds can take some persistence. Mark the site with a stalk during the plant’s showy phase and look on the ground for seed capsules.... Sow the seed soon after collecting them.... Plant seeds in a shaded seedbed, or stratify them in a flat in the refrigerator for six weeks, and then set the flat outdoors in a sheltered spot. Keep the seedbed moist, and the plant the seedlings in rich damp soil that receives some shade.... They like light to moderate shade and rich, moist soil with plenty of humus." [NSSH Bubel]
