Rainy Side Notes

 

Here we have a vine with an identity crisis because of all the name changes it has been through, almost as many as sweet autumn clematis. Actually, I am having the crisis. I cannot get used to calling my lovely vine, Clematis spooneri—C. montana var. sericea—even though I often thought it looked similar to C. montana. Regardless of how I feel about it, the name has been changed back to the original epithet botanist Franchet gave it in 1907—Clematis montana var. sericea. I hope the name will stick the second time around. Most sources you find on this particular clematis point to Clematis spooneri. It will take awhile before the new/old name catches on in the garden community.

Now that we have the name business taken care of, let us talk about where this clematis should grow in the garden. No wimpy arbors for this one; like most clematis in the montana group, it will swamp a flimsy arbor in record time. Give it a beefy structure to climb—perhaps the Seattle Space Needle.
