Cultivation / Plant breeding

Erigeron annuus (L.) Pers.

The preference is full or partial sun, and moist to mesic conditions. This plant isn't fussy about soil characteristics, and tolerates clay or gravel to a greater extent than many others. It's easy to grow, but can spread aggressively by re-seeding itself in disturbed areas. Sometimes the lower leaves will turn yellow and wither away during hot dry weather.

Sow spring in situ, and germination occurs in four weeks.
