Gardeners' Notes:


On Mar 31, 2015, coriaceous from ROSLINDALE, MA wrote:

Blooms on the previous year's growth---prune shortly after flowering.

This hybrid lacks the apple scent of C. floridus. 'Aphrodite' is a more complex hybrid that looks similar and is also fragrant.

Blooms best in full sun here.

Usually considered hardy to Z5.

Growth is very rapid, and the habit is a little rangy. Spreads by suckering.

Thankfully, due to recent changes in nomenclature, this is now correctly named Calycanthus x raulstonii 'Hartlage Wine'.

This season, here in CT, we had one rainy day after another, and behold this plant has borne at least 50 gorgeous blossoms. There are still 2 lingering on it now. We are so happy to have this addition.The only problem is that over this spring & summer, the woody stalks of the plant have grown incredibly, are looking very rangey, awkward and unattractive. Could someone please tell me WHEN and HOW toprune my beautiful "Hartlage Wine" Calycanthus.....I'm new to this site(joined about half an hour ago), and will try to post a photo of this plant.The photo, however was taken last summer when the plant didn't have as many blooms, but looked in far better ... read more
