Polemoniums grow best in cool, moist environments. They will grow in full sun in the northernmost reaches of their zone but prefer afternoon shade in the warmest regions where it grows. Keep plants watered during the warmest months of the season, but be sure the soil is well-drained, especially in winter. Cutting plants back by 1/3 after blooming may encourage sporadic rebloom in late summer.

Pests & Diseases:

Aphids, Thrips, Rhizoctonia aerial leaf blight, Rhizoctonia root and crown rot, Phythium root & crown rot, Phytophthora root and crown rot, occasionally viruses.

Moisture:

Grow at moderate moisture levels; growing too dry may lead to foliar burn, while excessive moisture can result in crown and root rots.

Planting Level:

Plant plugs with the soil line even with the soil line of the finished container.

PGRs/Pinching:

Pinching is not required. PGR may be used for toning if needed; apply uniconazole (Sumagic/Concise) as a spray at 5 ppm or paclobutrazol (Bonzi/Piccolo) at 20-30 ppm.

Lighting:

High light levels recommended. Long days are required for flowering (14+ hours). Lower light levels will result in less of the purple/burgundy coloration on the foliage.
