Plant Profile - Clematis

C. macropetala 'Jan Lindmark', Lindmark raised this cultivar in Sweden before it was
introduced to Britain by Raymond Evison in 1983.  It has
mauve-purple flowers and is one of the first spring flowerers.
It belongs to pruning group 1, so it needs virtually no pruning. Clematis in this group flower early in the year on stems
produced the previous year.  Little pruning is required other than to train them and keep them within bounds.  Enjoy their
prolific flowers but do not cut away any of the previous year's
growth.  Another, C. serratifilia 'Snow Queen',  grows on the north side of the garage and receives only 3 hours of morning sun.  It has not bloomed, but has lots of buds and will rebloom again in early autum.  The last clematis I own in this group is 'Scartho Gem'. It was a new purchase last summer, I do not know if it will flower this year. It has no buds.  It was introduced by Pennells in 1973 and is a bright pink color with wavy eadges.

Group 2 includes those that flower in early summer, again on woody stems produced in the previous year.  These need to be pruned lightly in early spring since they are only a few weeks away from flowering, but they do need some of last year's growth removed, especially where it is dead.  Check by breaking a piece of stem well away from the plant to see if it is green and healthy inside.  If not, then it is dead at this extremity and may be removed.

Group 3 includes the late summer and autumn flowering clematis that flower on the current year's growth.  You can remove some of the old growth after flowering in autum, since this will prevent the plant from being damaged in winter.  This group are best pruned hard in early sping, when they are still many weeks away from flowering.  Cut back to a pair of buds  from where you would like the plant to burst forth, or at about the lowest set of buds from the ground. I own two clematis in this group, C. viticella 'Polish Spirit' and C. intergrifolia 'Blueboy', they will not flower until July or August.

This clematis is flowering in the garden now.
Have a wonderful weekend.

What a pretty clematis. The blooms remind me of giant columbine blooms. The bees are loving it.
Have a wonderful weekend.

We're clematis fans here, too. We have four right now, two already in bloom, and two not quite there yet.

Thanks for sharing the helpful information and the beautiful pics.

Beautiful photos and interesting reading.

I have a 'Pope John Paul' clematis which isn't thriving at all. I don't think it gets enough sun.

I have a place to move it into full sun, and plan on doing that tomorrow.

Enjoy the rest of the weekend.
