Abstract: A new and distinct Hosta plant characterized by very dark maroon petioles with maroon leaf bases, thick, glossy, dark green leaves, camptodrome venation, a vigorous, clumping habit, on a medium size plant.
Claim: I claim:

1. A new and distinct hybrid Hosta plant as herein shown and described.
Description: Botanical denomination: Hosta hybrida.

Variety designation: `Purple Heart`.


The present invention relates to a new and distinct cultivar of Hosta, botanically known as a Hosta hybrida, and hereinafter will be referred to by its cultivar name `Purple Heart`. Hosta is in the family Hostaceae. The plant is theculmination of a breeding program for red petiole and leaf base Hosta. It was bred in Canby, Oreg. using unpatented proprietary parents. The exact parents are unknown.

Compared to Hosta `Invincible` (an unpatented plant), Hosta `Purple Heart` has a similar leaf color and texture. The new variety has a dark leaf base and a darker petiole.

Compared to Hosta `Little Red Rooster` (an unpatented plant), Hosta `Purple Heart` is a larger plant with deeper green foliage and a dark leaf base that continues further up the leaf.

Compared to Hosta `Red October` (an unpatented plant), Hosta `Purple Heart` has a larger habit and a deeper color in the leaf base.


This new cultivar is unique in the combination of: 1. very dark maroon petioles with maroon leaf bases, 2. thick, glossy, dark green leaves, 3. camptodrome venation, 4. a vigorous clumping habit, 5. and a medium size plant.

This new cultivar has been reproduced only by asexual propagation (division and tissue culture). Each of the progeny exhibits identical characteristics to the new cultivar. Asexual propagation by tissue culture using standard micropropagationtechniques with lateral shoots as done in Canby, Oreg., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations. The present invention has not been evaluated underall possible environmental conditions. The phenotype may vary with variations in environment without a change in the genotype of the plant.


FIG. 1 shows a two-year-old plant in a 4 inch pot in July in Canby, Oreg.

FIG. 2 shows flower stalk in late September.
