Flowers open like dazzling butterflies, in the brightest red you can get, crowding two foot stems for a very long time in mid-summer. Although it will grow in any good soil, it is a superb plant for boggy or even wet conditions and in the margins of a pond it makes a stupendous sight.
Sow immediately at any time onto preferably a soil-based compost, covering with fine grit to approximately their own depth. Germination MAY be quicker if kept at 15 to 20 degrees C. but many seeds WILL NOT come up the year they are sown, needing winter chilling after sowing, and ONLY come up with natural spring germination.
Common name:Lobelia Red Cardinal
