Huge lavender/blue flowers, blooms in late May/early June and then reblooms. Mine is growing on a chain link fence, in a strip of dirt between two sidewalks, where I haven't had much luck growing anything but weeds. I covered the roots with a rock. It is thriving.

My best Clematis (of six that I have), Ramona is the most consistent performer with the biggest blooms and the most otherworldly shade of lavender-blue.

Definitely recommend. My soil is poor, and she's in part-shade, and she's happy as a clam at high tide.

I planted small specimens last year. This year they are quite vigorous and carefree growers, topping their trellises now in early June. Also very floriferous, with a terrific May spectacle of large flowers in striking blue/lavender shades covering the plants. I expect additional blooms later in the season. Very pleased with 'Ramona.'

I have seen this plant blooming prolifically. My son used the tiller on mine. I liked it so well, I bought another one.

This clematis gives an outstanding display each May. It blooms sporadically thereafter all the way till winter. The seedheads are attractive year-round.

I planted this type of Clematis earlier this spring, and it's doing so well. It has climbed up my trellis aon on to my fence. It's blooming profusly now. Definately a good vine for zone 7.

Positive sadie_mae On Dec 11, 2004, sadie_mae from Central, KY (Zone 6b) wrote:

I love the color of this clematis the most during it's first few days, then it tends to fade; still pretty, I just prefer the new blooms. Has grown very well. It is in full sun, maybe the blooms wouldn't fade as much in partial shade.
