Alstroemeria plant named `Stalra`

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 seedlings; namely, 82R473-6 as seed parent and 87G1069-2 as pollen parent. The varietal denomination of the new variety is `Stalra`.

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

SUMMARY OF THE INVENTION

The new variety of Alstroemeria, `Stalra`, produces large flowers.

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 illustration of this type.
