Alstroemeria named Stalilas

Abstract

A new alstroemeria variety, originated as a seedling in greenhouse at Aalsmeer, Holland, resulting from my crossing of selected greenhouse varieties, grown for breeding purposes at Aalsmeer, with the object of developing new flower color in plants having good flowering characteristics during the fall, winter and spring months. This particular seedling was selected for propagation and testing because of its very lovely light purple coloring and its profuse production of blooms borne on relatively long and strong peduncles. Propagation of this cultivar through successive generations at Aalsmeer, by division of root stocks, has demonstrated that its novel characteristics hold true from generation to generation and appear to be firmly fixed.

Description

DESCRIPTION OF THE DRAWING

My new alstroemeria variety is illustrated by the accompanying photographic drawing which, in full color, shows the inflorescence of this plant as it appears at the top of the flowering stem, the colors shown being as nearly true as is reasonably possible to obtain by conventional professional photographic processing techniques.
