Gardeners' Notes:

No clematis has true blue flowers. The closest are a blue-violet.

Blackened crispy leaves are often due to a common fungal disease called clematis wilt. Large-flowered clematis are more prone to clematis wilt than the species and small-flowered hybrids.

Clematis and tomatoes are two exceptions to the usual rule, and are best planted 6 inches deeper than the soil level in the pot. This protects the stem bases from mechanical damage, and helps prevent clematis wilt, whose fungus enters where there's damage. It also helps keep the roots cool.

Many small-flowered hybrids are spec... read more

This clematis took about three years to get established but it is well worth the wait. It is making its living in a 3b - 4a climate and is doing well. The color, contrary to other reports, is a beautiful blue. I'd say it's about the color of a faded pair of blue jeans. We have naturally alkaline soil here with a deficiency (absence?) of iron and magnesium. Maybe that contributes to the color?

My Will Goodwin is blue, but maybe that is because it does not get full sun. Aside from the color, I love the huge blooms. It's a stunner that always makes me smile.

This clematis grows well, but disappointed that it was not anything close to the blue that was advertised. Like the photos here, mine is purple. The seed heads are fabulous year-round and almost worth the incorrect color description. That said - don't buy this varirty if you want a true blue clematis.

Very pretty flowers, but I was disappointed that it was not the true blue shown and described in catalogs. Maybe in other gardens with other soil conditions it would be blue. I love Clematis though, so it is still a keeper. This is actually one of my favorites. Blooms June-August in my garden.

I live 4 miles from the nursery, Pennels, which produced this clematis. I did, however, buy this as a young plant from a local supermarket, who sell plants from a major supplier. I have noticed this plant has a reddish/purple flush radiating from the centre along the midribs, and am not sure if this is because of the soil it is growing in, or is a trait carried through from the original source.

I like this clematis, it's color is so pretty. I'm waiting for mine to be blue tho, not purple!

This plant is only 1 year old and has surpassed any of my expectations, it only had two blooms so far. The flower lasts a little over one week, which surprised me and it's petals are quite firm to the touch.

I added this clematis hybrid around 1998. It took off within a year and has been a reliable bloomer and very hardy. I have the roots shaded by a spirea bush. Generally blooms in late June, most years it will rebloom in August. We have acid soil and I find that the blooms tend to be more purple than the "powder blue" noted on the card that came with it. It recommends a soil PH of 6.0 - 6.5. I like the color and the vine is doing well, so why fix something that's not broken?

The picture I uploaded was taken when the vine was about 3 years old - it's more than doubled it's size now.
