This favourite blooms from July through to September and is an Ontario native plant. Golden yellow blooms with dark centre.

How to Grow

3700 seed/gram. This robust perennial will turn heads wherever planted and withstand more heat and drought than most. It is highly recommended to sow this type outdoors from September through October – select a site in full sun. This fall sowing allows any dormant seed to be naturally stratified over the winter. Seed can be started indoors in a soil-less mix from February to the beginning of March. Germinates at 20 C (70 F) in 14 to 21 days. Grow on under lights at a slightly cooler temperature before hardening off and transplanting outdoors to a sunny spot.
