We moved to Laval North 2 years ago and planted Marie Boisselot with other Clematis . It is so beautiful and flowers from June to late September early October which is rare for Quebec. I would like to purchase 2 more but can not find the plant here.

This is second year. Grew about 6 feet last year but no blooms. Cut to 1 foot late winter and is now up about 5 feet and has several beautiful huge (5" - 6") white blooms. Very impressive for a Clematis down here (Gainesville FL 8b/9a depending on who you talk to).

Beautiful large pure white flowers on a vine that climbs up nicely on a trellis. It has more flowers and blooms more consistently than Henryi, it also has larger flowers. I would consider it one of the best whites, far surpassing both Henryi and Gillian Blades in my garden.

These blooms are so large and beautiful they look like gleaming white water lilies climbing up your trellis.

When this plant gets established it has the most beautiful flowers, but so far has not grown very tall in the 6 years I have had it. An occasional slightly heavier prune may encourage it. I purchased this as Madame le Coultre, syn. Marie Boisselot, and in most places you will find this is claimed.

However, as found on clematis.hull.ac.uk it is as follows:
'Marie Boisselot' is extremely similar to 'Mevrouw Le Coultre' which is sometimes (wrongly) listed as a synonym. Victoria Matthews, the International Clematis Registrar, notes that the anthers on 'Marie Boisselot' are completely yellow whilst on 'Madame Le Coultre' the connectives quickly go black at the tip.

On careful inspection of mine, in the absence of the black tips to the anthers I must assume it is Marie Boisselot.

We've had a wild ride with this one. At the outset it was given to wilt and did so repeatedly inside the first two years. In its third year it became shielded by a Westerland bush; it might be that or it might be that it's simply a mature plant now - in any case it came back with a vengeance and is a big strong heavily flowering mass now.
