I took these pictures this morning of the clematis vine on my mailbox. This one is named Jackmani and is several years old. Jackmani blooms on new growth so I prune it back to about 12" in March, put a cup of lime around it and fertilize it.
The clematis was just a few years old in this picture.
This girl was only 11 weeks old. Can't imagine trying to get her in the mailbox now!
