I live on the old toll road to Albany, NY (Zone 5a) so felt like this plant had to be in my garden. Its planted along a fence that abuts a very busy road. It has to tolerate full sun, heat from the pavement, open wind in the winter, and road spray. It is an amazing workhorse and comes back year after year in full bloom. It is expansive and gives even the honeysuckle a run for its money. Love this clematis.

This C. texensis hybrid has been vigorous for me (Boston Z6a), and a reliable bloomer, but it's been a small, light plant to 7' or so. It does clasp with its petioles for climbing, but it is herbaceous here---the stems don't survive the winter and can be safely cut to the ground when the leaves are brown in autumn.

Seems to need sun for best flowering. Works well as a scrambler in a perennial border. Makes a good cut flower.

I haven't seen powdery mildew on mine.

This is a hybrid between C. texenis and C. x 'Star of India'.

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 ... read more

I have several varieties of this, all grown from commercial roots, and love them all. According to my research, the best method of propagating these is by burying the middle section of a shoot after removing the leaves. Leave it alone until the end of the following spring. At the end of that spring/beginning of the summer after it has been buried for the previous summer and winter, check that you do have roots on the buried section. If you do (and I usually do) then you can simply clip the section off that you are rooting and move it to its "forever" home.

Extremely vigorous and blooms like crazy. Gets ginormous and needs a VERY sturdy trellis.

A very pretty flower, bloomed most of the summer, a delite to look at. Last year, (2005) was it's second year in my garden. This spring it has taken off, hope the trellis is strong enough might need support.

This is a beautiful and vigorous clematis. I made the mistake of growing through my rose bush Stanwell Perpetual and it just is way too vigorous - it smothers it each year by fall. Still I like it - I just need to find it another spot.

Here in Texas (zone 8a) this plant's performace has been excellent, non-stop blooming from May till frost. No disease or insect problems, not even powdery mildew. Hard to find, but worth the search!

A very pretty Clematis, but prone to mildew, by all accounts. I hope that I can avoid major problems by keeping it well mulched and having it trained on a trellis that has good airflow on all sides.
