Abstract: A new and distinct cultivar of Distylium plant named `PIIDIST-I`, characterized by its compact, upright-spreading growth habit, yellow-green new growth, dark green mature foliage, and reddish purple flowers.
Claim: I claim:

1. A new and distinct Distylium plant named `PIIDIST-I`, as illustrated and described herein.
Description: Genus and species of plantclaimed: Distylium sp. hybrid.

Variety denomination: `PIIDIST-I`.


The present invention relates to a new and distinct cultivar of Distylium plant, botanically known as Distylium sp. hybrid, a member of the Hamamelidaceae, and hereinafter referred to by the cultivar name `PIIDIST-I`.

`PIIDIST-I` originated as an open-pollinated seedling from seed collected from a Distylium sp. hybrid (Distylium myricoides.times.D. racemosum) growing in Watkinsville, Ga. `PIIDIST-I` was selected in the summer of 2006 by the inventor in acultivated environment in Dearing, Ga.

Asexual reproduction of `PIIDIST-I` by stem cuttings, performed in Watkinsville, Ga., since 2006 has shown that all the unique features of `PIIDIST-I`, as herein described, are stable and reproduced true-to-type through successive generations ofsuch asexual propagation.


Plants of the new cultivar `PIIDIST-I` have not been observed under all possible environmental conditions. The phenotype may vary somewhat with changes in light, temperature, soil and rainfall without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be unique characteristics of `PIIDIST-I`. These characteristics in combination distinguish `PIIDIST-I` as a new and distinct cultivar: 1. Compact, upright-spreadinggrowth habit; 2. Yellow-green new growth; 3. Dark green mature foliage; and 4. Reddish purple flowers.

Plants of `PIIDIST-I` differ from plants of the parent, Distylium sp. hybrid, primarily in growth habit, foliage color, and cold hardiness, as plants of `PIIDIST-I` have a smaller, more compact, upright-spreading growth habit, large lustrousdark green mature foliage, and increased cold hardiness, whereas plants of the parent have a larger, less compact, upright, spreading growth habit, smaller medium green foliage, and are less cold hardy.

Plants of the new Distylium `PIIDIST-I` can be compared to plants of the cultivar `PIIDIST-II` (U.S. Plant patent application Ser. No. 13/068,251), which is a sibling that originated from the same open-pollination. `PIIDIST-I` has a compact,upright-spreading growth habit, yellow-green new growth, dark green mature foliage, and reddish purple flowers, whereas `PIIDIST-II` has a compact, spreading growth habit, maroon-purple new growth, dark blue-green mature foliage, and reddish maroonflowers.

Plants of the new Distylium `PIIDIST-I` can be compared to plants of the cultivar `Vintage Jade` (U.S. Plant Pat. No. 23,128), which is a sibling that originated from the same open-pollination. `PIIDIST-I` has a compact, upright-spreadinggrowth habit, yellow-green new growth, dark green mature foliage, and reddish purple flowers, whereas `Vintage Jade` has a compact, layered mounding and spreading growth habit, light green new growth, dark green mature foliage, and reddish maroonflowers.


The accompanying color photographs illustrate the flower and foliage characteristics and the overall appearance of `PIIDIST-I`, showing the colors as true as it is reasonably possible to obtain in color reproductions of this type. Colors in thephotographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of `PIIDIST-I`.
