The question was posed how to tel cristata foliage and verna apart at this time of year. Attached are some photos that may help. the verna foliage is narrower and more swordlike. The cristata foliage is somewhat wider towards the middle and tends to curl downward about midway. There are three promineant nerves on the verna foliage and about 4-6 on the cristata foliage bot have one side of the leaf that is somewhat glaucous and a mat finish with the other side being less so and more shiny. Cristata leaves have this variation also but it is much less pronounced. The rhizome creeping on the ground tends to hover slightly above it but verna tends to be more submerged. The mountain form of verna tends to have the alternately swollen then constricted rhizomes much like cristata. Verna I believe grows more in the open whereas cristata favors denser shade. I hope this helps. El and Dennis, |
