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

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

Variety denomination: `PIIDIST-II`.


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-II`.

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

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


Plants of the new cultivar `PIIDIST-II` 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-II`. These characteristics in combination distinguish `PIIDIST-II` as a new and distinct cultivar: 1. Compact, spreading growthhabit; 2. Maroon-purple new growth; 3. Dark blue-green mature foliage; and 4. Reddish maroon flowers.

Plants of `PIIDIST-II` differ from plants of the parent, Distylium sp. hybrid, primarily in growth habit, foliage color, and cold hardiness, as plants of `PIIDIST-II` have a compact, spreading growth habit, maroon-purple new growth, darkblue-green mature foliage, and increased cold hardiness, whereas plants of the parent have an upright, spreading growth habit, medium green mature foliage, and are less cold hardy.

Plants of the new Distylium `PIIDIST-II` can be compared to plants of the cultivar `PIIDIST-I` (U.S. Plant patent application Ser. No. 13/068,262), which is a sibling that originated from the same open-pollination. `PIIDIST-II` has a compact,spreading growth habit, maroon-purple new growth, dark blue-green mature foliage, and reddish maroon flowers, whereas `PIIDIST-I` has a compact, upright-spreading growth habit, yellow-green new growth, dark green mature foliage, and reddish purpleflowers.

Plants of the new Distylium `PIIDIST-II` 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-II` has a compact, spreading growthhabit, maroon-purple new growth, dark blue-green mature foliage, and reddish maroon 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-II`, showing the colors as true as it is reasonably possible to obtain in color reproductions of this type. Colors inthe photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of `PIIDIST-II`.
