The Chelone glabra with its white flowers tinted with pink is a plant whose growth is rather fast. One will thus provide it with enough space to develop. It appreciates humid, peaty and even swampy conditions.

Sowing method : Mix seeds with an equal amount of damp sand or vermiculite. Place the mixture in a sealed plastic bag. Store the bag in a refrigerator or cool storage room for 90 days. Sow seeds when there is no risk of ground frost. Or plant the seeds outdoors during the fall. Germination will occur the following spring or later on.
