I've pined away for this clematis for years and finally found it in my local garden center. Something has eaten each and every leaf off of it. It's attempting to releaf but don't know if it will recover.

This is probably a plant like many I have planted. The saying goes: 'First they sleep, then they creep, then they leap" By the third year, most of the time, the plant reaches full maturity and behaves and looks like the pictures! Have patience!

So far my experience is negative. In May of 2010 I bought this plant from a high quality nursery and it was covered in beautiful yellow blooms. In Summer 2011 it grew like crazy but never bloomed. We'll see what happens in 2012.

I am in zone 4B also, and planted this clematis on a south facing trellis... and like negative response , had just a few blossoms, and a tangle of leafy growth... so in this , its 3rd year I was thinking of replacing it, and voila..... it is covered with buds! I cant wait until it blooms. Perhaps it just takes a while to get going. The only thing I did different this year was to give it 1/4 cup of clematis starter in the spring.
Patience, have patience ....

This plant is rare to get in Toronto which is too bad because it has been doing so well in my backyard! I have found it very easy to grow! I also love it because it is a late bloomer. It's been admired by many visitors and everybody would like to have it.

Got the seeds from Park's, and they germinated well. Set it out last spring, and watched it do not much the whole summer. Good on you folks who got flowers first year from seed! Forums I've read suggested that what I got was pretty normal while seedling clematis gets established, and the next year would be better.

So far in year 2 (July 11) it's growing nicely up the trellis (at about 30" now) with nice-looking, bright mid-green foliage, but no flowers yet. Hopeful to see some this summer, and expecting that the third year will be the charm for vigorous vine with lots of little yellow bells.

I may be back later to change my rating to positive, since I do like having this clematis, and I'm happy I was able to grow it from seed; but for all those folks who are reading 'flowers first year from seed' advertising, I'm keeping this entry toned down for now.

A very easy clem to start from seed; will bloom the first year. A wonderful yellow clem. Seedheads make a wonderful display. Does require a bit more assistance to behave, but the color and form is worth the effort. Young plants were kept in hanging basket last year, which went thru 18F freeze and came back strong even before the last frost; no damage from late frosts.
