Abstract: A new and distinct Hosta plant characterized by the combination of creamy white-centered foliage with green margins and strong red petioles and flower stalks. In the spring the red of the petioles shows up in the base of the leaf as well. Hosta `Raspberry Sundae` has a compact habit and attractive violet flowers in late summer into fall.
Claim: I claim:

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

Variety designation: `Raspberry Sundae`.

BACKGROUND OF THE INVENTION

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 `Raspberry Sundae`. Hosta is in the family Hostaceae. The plant is theculmination of a breeding program for variegated, red petiole Hosta. It was bred in Canby, Oreg. using unpatented proprietary parents. The exact parents are unknown.

Compared to Hosta `Cherry Berry` (an unpatented plant), Hosta `Raspberry Sundae` has a larger habit, larger and wider leaves, and darker petioles and scape. Compared to other red petiole Hosta, the new cultivar is variegated with creamy whitecenters and green margins rather than not variegated.

SUMMARY OF THE INVENTION

This new cultivar is unique in the combination of creamy white-centered foliage with green margins and strong red petioles and flower stalks. In the spring the red of the petioles shows up in the base of the leaf as well. Hosta `RaspberrySundae` has a compact habit and attractive violet flowers in late summer into fall.

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.
