Description

Lilium canadense Linnaeus 1753

Origin:
North America, Canada; moist, grassy areas

Laboratory comment:
Lilium canadense has proved not to be the easiest species in-vitro. In the beginning it takes felt centuries for germination and this species appears as a true Princess in the medium, sulking soon when the medium-recipe doesn´t fit to its Royal needs. It worked better when we started replating the seedlings every few months into a new medium with a rather neutral and balanced pH.

Taxonomy:
Kews describe no infraspecifics although canadense owns an incredible variety of colors and patterns in its flowers. One is inclined to distinguish var. flavum, rubrum, coccineum, editorum (the latter listed separately) and clones which are anyhow in-between. Most of the flower-colours and patterns can be kept when acting carefully in the pollination and the expected colour-types usually come true from seeds. We are tried keeping the different clones/strains plainly apart from each other.
