Abstract: A new cultivar of Weigela plant named `April Snow` that is characterized by its pure white flowers and bright green leaves. In combination, these traits set `April Snow` apart from all other varieties of Weigela known to the inventor.
Claim: What is claimed is:

1. A new and distinct variety of Weigela plant named `April Snow` as described and illustrated.
Description: Genus: WEIGELA.

Species: praecox.

Denomination: `APRIL SNOW`.


This application claims the benefit of priority under 35 U.S.C. 119(e) of U.S. Provisional application No. 60/903,620, filed on Feb. 26, 2007, entitled WEIGELA Plant named `April Snow`.

The present invention relates to a new and distinct cultivar of WEIGELA grown as an ornamental plant for use in the garden and landscape. The new cultivar is known botanically as WEIGELA praecox and will be referred to hereinafter by thecultivar name `APRIL SNOW`.

The new cultivar `APRIL SNOW`was selected by the inventor from a crop of seed sown Weigela praecox (species, unpatented) at the inventor's nursery in Clarkson, Nebr. It was the only plant in a group of 2500 seedlings with pure white flowersinstead of pink flowers as is typical of the species.

The closest comparison plant is the commonly sold Weigela praecox. `APRIL SNOW` differs from the pink-flowered species in respect of its large pure white flowers.

Asexual reproduction by softwood cuttings of the new cultivar `APRIL SNOW` was accomplished in 2000 in Clarkson, Nebr. by the inventor. Since that time, under careful observation, the unique characteristics of the new Weigela plant have beenuniform, stable and reproduced true to type in successive generations of asexual reproduction.


The distinguishing characteristics of the new Weigela cultivar `April Snow` are as follows. These traits in combination distinguish `April Snow` as a new and distinct cultivar when compared with all other existing varieties of Weigela known tothe inventor. `April Snow` has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, however, without any variance in genotype. 1. `APRIL SNOW`bears pure white funnel-shaped flowers in dense clusters from April through June. 2. The flowers of `APRIL SNOW` maintain their color with no tendency to turn pink with age. 3. The foliage of `APRIL SNOW` is bright green. 4. `APRIL SNOW` isvigorous and reaching a height of 6 feet in height and 5 feet in width. 5. `APRIL SNOW` is suitable for use as a garden or landscape plant. 6. `APRIL SNOW` grows well in moist well-drained soils in full sun to partial shade. 7. `APRIL SNOW` ishardy to USDA Zone 4.


The accompanying color drawing illustrates the distinguishing characteristic of `APRIL SNOW`, namely the cymes of pure white flowers. In all other respects, `APRIL SNOW` resembles the parental species Weigela praecox, whose flowers are coloredpink.

The plant used for preparing the drawing was grown outdoors at the inventor's nursery in Clarkson, Nebr.

The drawing has been made using conventional techniques and although colors may appear different from actual colors due to light reflectance, they are as accurate as possible by conventional photography.


The following is a detailed description of the Weigela cultivar named `April Snow`. Data was collected in Colfax, N.C. from 6 month old plants that were container grown outdoors. Color determinations were made in accordance with The 2001 RoyalHorticultural Society Colour Chart from London England, except where general color terms of ordinary dictionary significance are used. The growing requirements are similar to the species and there are no disease problems known to the inventors. Botanical classification: Weigela praecox `April Snow`. Genus: Weigela. Species; praecox.
