Alstroemeria plant named `Stapristef`

Abstract

A new and distinct Alstroemeria plant variety producing flowers of good quality and attractive coloration.

Description

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of Alstroemeria which is a cross of two unnamed, undistributed varieties identified as seed parent 91D185-5 and as pollen parent 87G10692. The varietal denomination of the new variety is `Stapristef`.

The first act of asexual reproduction of `Stapristef` was in Aalsmeer, The Netherlands, by propagation by dividing rootstocks. Asexual reproduction by dividing rhizomes and tissue culture through successive generations in Aalsmeer, The Netherlands, has demonstrated that the combination of characteristics as herein disclosed for `Stapristef` are firmly fixed and retained through successive generations.

SUMMARY OF THE INVENTION

The new variety of Alstroemeria, `Stapristef`, produces long lasting flowers of unusual coloration, as described herein.

DESCRIPTION OF ILLUSTRATION

The new variety of Alstroemeria hybrid is illustrated in the accompanying illustration, which shows typical flower characteristics, with colors being as nearly true as is possible for illustrations of this type.

DETAILED DESCRIPTION OF THE NEW VARIETY

The following is a detailed description of the new cultivar of Alstroemeria hybrid plants about one year old as observed in a greenhouse in Aalsmeer, The Netherlands on the month of October. Color designations indicated are in accordance with The Royal Horticultural Society Colour Chart by color plate designations.

`Stapristef` has not been observed under all possible environmental conditions. Phenotypic expression may vary with variations in environment such as temperature, light intensity, day length and growing and cultural conditions.
