| Abstract: |
A new and distinct Iresine plant cultivar is disclosed, characterized by a distinct leaf color of dark purple foliage with magenta veins; magenta petiole and stems; strong stems; and an upright growth habit. |
| Claim: |
What is claimed is:
1. A new and distinct cultivar of Iresine plant named `AUREO M` as herein illustrated and described. |
| Description: |
Latin nameof the genus and species: Iresine herbstii.
Variety denomination: `AUREO M`.
BACKGROUND OF THE INVENTION
The new cultivar is the product of an induced mutation. Aureo M was discovered as a single plant by Leo van Zanten in March 2005 in a cultivated area of Oxnard, Calif. in a greenhouse. Two thousand unrooted cuttings from Iresine herbstiibrilliantissima were irradiated with gamma rays at a dose of 25 Gy. The treated cuttings were planted for rooting and growing. Subsequent selection among the population resulted in the discovery as a single plant of this new variety.
Asexual reproduction of the new cultivar `AUREO M` by terminal cuttings was performed in Oxnard, Calif. and has shown that the unique features of this cultivar are stable and reproduced true to type on successive generations.
SUMMARY OF THE INVENTION
The cultivar `AUREO M` 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 `AUREO M.` These characteristics in combination distinguish `AUREO M` as a new and distinct Iresine cultivar: 1. Distinct leaf color oflight magenta with darker purple veins; 2. Magenta petiole and stems; 3. Strong stems; and 4. Upright growth habit.
Plants of the new cultivar `AUREO M` are similar to plants of the parent variety, Iresine herbstii brilliantissima, in most horticultural characteristics, however, plants of the new cultivar `AUREO M` have an upright growth habit compared to thecompact growth habit of the parent. Additionally, the petiole and stems of `AUREO M` are magenta compared to the dark purple of the parent variety. Finally, the longevity of `AUREO M` is several weeks longer.
In comparison to the variety `AUREO LG` (U.S. Plant patent application No. 11/823,297), `AUREO M` has light magenta and dark purple colored foliage compared to the lime green foliage of `AUREO LG`.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying photograph in the drawing illustrates in full color a typical plant of `AUREO M` grown in a 2 gallon container. One cutting was used in the pot. The colors are as nearly true as is reasonably possible in a color representativeof this type.
DETAILED BOTANICAL DESCRIPTION

The following observations and measurements describe `AUREO M`plants grown in Oxnard, Calif. during the months of January through April. The growing temperature ranged from 12.degree. C. to 15.degree. C. at night to 12.degree. C. to 20.degree. C. during the day. Measurements and numerical values representaverages of typical plant types. Botanical classification: Iresine herbstii cultivar `AUREO M.` Commercial classification: Bloodleaf.
