Alstroemeria plant named ‘Mauve Majesty’

Abstract

An Alstroemeria cultivar particularly distinguished by its mauve flower color, its strong, upright flower stems, its winter hardiness, and its continuous flowering from beginning of summer until the first hard freeze in the fall is disclosed.

Description

Genus and species: Alstroemeria hybrid L.

Variety denomination: ‘Mauve Majesty’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Alstroemeria, botanically known as Alstroemeria hybrid L., and hereinafter referred to by the cultivar name ‘Mauve Majesty’. ‘Mauve Majesty’ originated from a hybridization made in 2002 in Riverhead, N.Y. The female parent was an Alstroemeria aurea plant (unpatented), while the male parent was the proprietary Alstroemeria plant ‘Purple 1’ (unpatented).

Fifteen days after pollination, embryos were aseptically removed in ovulo and cultured on a one-quarter strength Murashige and Skoog medium. When the embryos germinated in vitro, they were subcultured to full-strength Murashige and Skoog medium for continued development. Once they were large enough to remove from the culture vessel, they were acclimated and grown in the greenhouse for trial. A single plant selection was chosen for further evaluation and for asexual propagation in 2002 in Riverhead, N.Y.

‘Mauve Majesty’ was selected for its distinctive mauve flower color, continuous flowering, and strong, upright flower stems. It was also selected because it is winter hardy to temperatures as low as those experienced in USDA zone 5. ‘Mauve Majesty’ has been asexually propagated repeatedly by rhizome division and tissue culture since 2002 and has been found to retain its distinctive characteristics through successive asexual propagations.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of ‘Mauve Majesty’. The data which define these characteristics were collected from asexual reproductions carried out in Riverhead, N.Y. The data were collected on plants grown under field conditions in full sun. 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

The female parent, Alstroemeria aurea (unpatented), is a species that is native to southern Chile and it differs from ‘Mauve Majesty’ by having yellow to orange flowers and by flowering only in the spring and early summer whereas ‘Mauve Majesty’ has mauve flowers and flowers continuously from the beginning of summer until the first hard freeze in fall.

The male parent, ‘Purple 1’ (unpatented), has larger flowers than ‘Mauve Majesty’ with a different shade of purple and is not as floriferous as ‘Mauve Majesty’. In addition, ‘Purple 1’ is not hardy to USDA zone 5, whereas ‘Mauve Majesty’ is hardy to USDA zone 5.

‘Mauve Majesty’ differs from the commercial Alstroemeria cultivar ‘Sweet Laura’ (U.S. Plant Pat. No. 10,030), by having mauve flowers that lack fragrance, whereas ‘Sweet Laura’ has yellow flowers that are fragrant. Both cultivars are winter hardy to USDA zone 5.
