This is what I'm finding so far. Would you agree?

Clematis âÂÂHagley Hybridâ - Soft pink flowers are 5-6" across and have ruffled edges and red anthers. Vigorous grower. Blooms June and September. Soil Condition: Normal. Full Sun to Mostly Sunny. Zones: 4-10. Height: 7-8'. Pruning Type 3.

Clematis âÂÂMrs. N. Thompsonâ - Deep blue red petals with a scarlet central bar. Blooms May, June, and September. Large flowers (4-6"). Height: 4-9'. Full Sun to Mostly Sunny. Zones: 4-10. Soil Condition: Normal. Pruning Type 2.

Clematis âÂÂPiiluâ - On mature plants, the first flush of blooms appear from the old wood as 3-4" double or semi-double light pink flowers with rose bars. However, in the early Fall the single flowers of similar coloring bloom from the current season's growth. Clematis Piilu is noted for being one of the heaviest blooming clematis. Blooms May through July and September. Height: Tall 4-6'. Sun-Shade: Full Sun. Zones: 4-10. Soil Condition: Normal. Pruning Type 2.

I can't help you here, sorry. But I was hoping someone would post with suggestions, because I just recently found out that there are indeed clematis that bloom twice. Was wondering if anyone has experience with a variety with this feature in my zone. The area I am thinking of placing it would get intense sun for the majority of the day, with shade very early and again very late in the day. Any ideas? Also, is there a company or catalog that is know for featuring clematis? Our area nurseries all carry the same varieties every year and I'm looking for something different. Thanks!

I've found Joy Creek Nursery to be a great source for Clematis offerings and information. Best of luck!

I know lots of information says that clematis blooms twice a year, but my experience is that the spring bloom is fabulous and anything after that is less than awe-inspiring. My Hagely Hybrid and Mrs. Cholmondeley just rebloomed, with about 3 blooms each. Maybe if I fertilized and watered better after the first flushes I'd have more luck, but as it is, it's not mind-blowing, and it usually isn't "fall" either, since they just finished doing it a week ago.
