Centranthus are long blooming and easy to grow. Flowers are produced from June all through the summer until frost. Best planted in groups. Freely self-seeds where happy.
This self seeder makes a gorgeous mass of flowers. Spring cleanup is recommended. Cut back established plants to 4" or pinch to promote sturdier well-branched growth. Remove spent blossoms to promote rebloom. Can be divided every 1-3 years in spring. Thrives in poor soil. Flowers longer in cool conditions. Fertilize every other year in late fall or late winter.
Our plants are all grown in plantable fiber pots that grow incredibly vigorous plants, eliminate transplant shock, and are 100% biodegradable. They have tremendous advantages over plastic pots.
