USPP20071P3 - Calla lily plant named ‘Hot Cherry BLZ’ - Google Patents

Abstract

A calla lily plant particularly distinguished by a purple-red spathe, low density maculation of the leaves that is visible from both sides and which produces 2 to 4 inflorescences per 3-cm tuber, is described.

Description

Genus and species: Zantedeschia spp.

Variety denomination: ‘Hot Cherry BLZ’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of calla lily, botanically known as Zantedeschia spp., and hereinafter referred to by the cultivar name ‘Hot Cherry BLZ’. The new cultivar was asexually reproduced from micropropagation resulting from the cross of the female parent calla lily, an unnamed seedling of Zantedeschia spp. (unpatented) with a pink spathe and the male parent calla lily ‘Majestic Red’ (patent status unknown) with a red/burgundy spathe.

The new cultivar was created in Tauranga, New Zealand and has been asexually reproduced repeatedly by micropropagation in India over a two-year period. The present invention has been found to retain its distinctive characteristics through successive propagations.

Plant Breeder's Rights for this cultivar were applied for in New Zealand on Oct. 6, 2006.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Tauranga, New Zealand.

• • 1. A purple-red spathe;
  • 2. Low density maculation of the leaves that is visible from both sides; and
  • 3. Produces 2 to 4 inflorescences per 3-cm tuber.

DESCRIPTION OF THE PHOTOGRAPHS

This new calla lily plant is illustrated by the accompanying photographs which show the mature inflorescence and foliage of the plant. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of a plant approximately 9 weeks-old, after planting.

FIG. 1 shows a close-up of the mature inflorescence.

FIG. 2 shows a close of a mature leaf with maculation.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed description sets forth the distinctive characteristics of ‘Hot Cherry BLZ’. The data that define these characteristics were collected from asexual reproductions carried out in Tauranga, New Zealand. The plant history was taken on two-year-old plants based on a 3-cm diameter tuber under New Zealand summer conditions. Color references are primarily to the R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.).

COMPARISON WITH PARENTAL AND COMMERCIAL CULTIVARS

When the instant plant is compared to the female parent, an unnamed seedling of Zantedeschia spp. (unpatented), ‘Hot Cherry BLZ’ has darker pink spathes and larger spathes than the female parent.

When ‘Hot Cherry BLZ’ is compared to the male parent, ‘Majestic Red’ (patent status unknown), ‘Hot Cherry BLZ’ has a brighter (lighter) spathe color and more inflorescences than the male parent.

‘Hot Cherry BLZ’ differs from the commercial cultivar ‘Hot Lips’ (U.S. Plant Pat. No. 15,260) in that ‘Hot Cherry BLZ’ has a higher spathe count, more consistently shaped spathes and the spathe color is more purple-red, while the spathe color of ‘Hot Lips’ is more pink.
