Abstract: A new and distinct Clematis patens cultivar named `UNAI 008` is disclosed, characterized by good resistance to normal diseases and pests of Clematis, continuous flowering from May through September, with flower buds continuously produced from the leaf axils, large flowers and tepals colored Violet Blue to Violet. Plants are exceptionally floriferous and vigorous. The new cultivar is a Clematis, suitable for ornamental garden purposes.
Claim: What is claimed is:

1. A new and distinct cultivar of Clematis plant named `UNAI 008` as herein illustrated and described.
Description: Latinname of the genus and species: Clematis patens.

Variety denomination: `UNAI 008`.

BACKGROUND OF THE INVENTION

The new cultivar is a product of a planned breeding program conducted by the inventor that began in 1978. The objective of the breeding program was to develop Clematis patens varieties with abundant, continuous, long season flowering, andplants with a good resistance to diseases and pests typical of Clematis. In 1981 the inventor, Aili Kivistik a citizen of Estonia, organized a group of unnamed, unpatented Clematis patens varieties for an open pollination breeding project. Seedsoriginating from this open pollination were planted out, and the new variety was selected in 1986. Specific parents of the new variety are unknown, as the seed was bulk collected, without noting the variety collected from. All work was conducted at anon-commercial nursery in Roogoja, Estonia.

In 1988 the inventor first propagated `UNAI 008` by vegetative cuttings at the same nursery in Roogoja, Estonia. Subsequent generations have shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar `UNAI 008` has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance ingenotype. The following traits have been repeatedly observed and are determined to be the unique characteristics of `UNAI 008` These characteristics in combination distinguish `UNAI 008` as a new and distinct Clematis cultivar: 1. Good resistance todiseases and pests common to Clematis. 2. Continuous flowering from May through September. 3. Very floriferous plants. 4. Flower buds produced continuously from the leaf axils. 5. Very large flowers. 6. Tepal color from Violet to Violet-Blue.

COMPARISON TO KNOWN VARIETIES

Plants of the new cultivar `UNAI 008` are similar to the known variety of Clematis patens `The President`, not patented in most horticultural characteristics, however, plants of the new cultivar `UNAI 008` flower continuously from May throughSeptember, whereas Clematis patens `The President` stops flowering for periods of time. Additionally the `UNAI 008` has a larger flower.

The new cultivar `UNAI 008` can also be compared to the known variety Clematis patens.times.lanuginosa `Dorami` U.S. Plant Pat. No. 21,740. Plants are similar in most horticultural characteristics, including the continuous flowering habit,however, plants of the new cultivar produce larger flowers. Flowers of `Dorami` are typically 10 to 14 cm in diameter whereas `UNAI 008` plant produce flowers from 16 to 18 cm. Additionally plants of the new cultivar produce flowers of a differentshade of Violet, and with a Violet-Blue center bar not produced by plants of `Dorami`.

The new cultivar `UNAI 008` can also be compared to the known variety Clematis patens `Zostiwa` U.S. Plant Pat. No. 20,372. Plants are similar in most horticultural characteristics, including similar flower color. However, plants of the newcultivar are more vigorous and spreading than `Zostiwa`. Additionally the new cultivar begins has larger flowers than `Zostiwa`.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical flowering plant of `UNAI 008` grown outdoors in Estonia. The plant is less than one year old.

FIG. 2 shows a close up view of a typical flower of `UNAI 008`.

The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
