Neutral	Joan	On Oct 3, 2009, Joan from Belfield, ND (Zone 4a) wrote: Editor's Note Some resources list all parts of all Clematis species poisonous if ingested. The toxic principal is Anemonin, and symptoms after ingestion include intense burning sensation in the mouth and mouth ulcers. Dermatitis and skin irritation has also been recorded, as have allergies and hay fever type symptoms from pollen inhalation. We tend to err on the side of caution in PlantFiles, and the danger notation in the details above is to caution gardeners, parents and pet owners to look further for more information.

We don't know where it came from but it is in a place where we normally have Dahlias.The flowers are about 5 feet up from the ground, the new buds are about 6 feet.

I bought this at a local hardware, had to contact the supplier on the tag for it's name. They sent this information along as well: Clematis florida var sieboldiana Vienetta: The blooms are 4 inches across, with pure white petals that turn chartreuse in the autumn chill. They surround a large, frilly center of black and purple that resembles a Passionflower! And they arise heavily in early to midsummer, continuing all season. Expect 50 or more blooms on a single plant of Vienetta! This climber reaches just 6 to 8 feet high, making it ideal for container growth as well as the garden soil. It is in Pruning Group 3, and is hardy in zones 6-9. Since it is supposed to be a hardier form of clematis florida 'Sieboldii', it should make it outside since clematis florida 'Sieboldii' is winter hardy in zone 7a.

It is also supposed to take part sun/full sun. I had mine outside getting part sun & it nearly died. I was not really sure if the sun was causing it to die so I planted it in full shade last Fall and it is growing like crazy. It even stayed evergreen during the winter, continuing to grow. It is one of the most stunning clematis I have & I have alot of them!
