Spathiphyllum plant name 'S48'

Abstract

A new and distinct Spathiphyllum cultivar named S48 is disclosed, characterized by very dark green, glossy foliage, rapid growth and early production of secondary shoots. The new variety can be produced commercial in tightly spaced pots and maintains its very dark green color under higher light conditions or low nutrient levels. The new variety is commercially suitable for 20 and 25 cm pot production. The new variety is a Spathiphyllum, typically produced as an indoor ornamental plant.

Claims

1. A new and distinct cultivar of Spathiphyllum plant named S48 as herein illustrated and described.

Description

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

[0011] The accompanying photograph in FIG. 1 illustrates in full color a typical plant of S48 grown in a greenhouse in Altha, Fla. This plant is approximately 10 months old, shown in an 8 inch pot.

[0012] FIG. 2 illustrates a view of the strong late shoot production. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

DETAILED BOTANICAL DESCRIPTION

[0013] In the following description, color references are made to The Royal Horticultural Society Colour Chart 2007, except where general terms of ordinary dictionary significance are used.
