Growing Conditions: Part shade in moist to average soil

Size: Height 2-3 ft, Spread 1-1.5 ft

Blooms: May

Landscape Use: Naturalized area, border plantings

Habitat Value: Attracts an array of host insects, including the pink-patched looper moth (E. thyatyroides), the columbine borer moth (P. leucostigma), and the columbine duskywing skipper (E. lucilius). Red columbine provides a nectar source for hummingbirds and various pollinators, including bumble bees (Bombus) and sweat bees (Halictidae). The seeds provide a food source for finches and buntings.

Pests & Diseases: Minor issue of leaf miner

Mature Seed Color: Black

Use a small brown bag to collect seeds from May to June when the seed heads have turned brown and the seeds can be heard “rattling” in the seed heads. Clip seed heads over the brown bag.

Collection & Cleaning Tips: Since the seeds are very small, use small brown paper envelope bags to collect seed heads. Tip seed head down to empty out the shiny black seeds. 

Store clean, dry seeds in a refrigerator (40°F) in a sealed glassine envelope.

Germination Requirements: These seeds need a winter or cold period to germinate — a minimum of 60 days exposed to temperatures in the range of 40°F and below. They also need light to germinate so plant on the surface of moist soil mixed with sand. Sow outdoors in pots November through February.
