plant named ‘Summer Glory’

Abstract

A new and distinct Philodendron plant named ‘Summer Glory’ particularly distinguished by unique reddish bronze colored foliage on young leaves, foliage that turns a dark, shiny green as foliage matures, durability, and relative freedom from pests, is disclosed.

Description

Genus and species: Philodendron hybrid.

Variety denomination: ‘Summer Glory’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct interspecific hybrid plant of Philodendron, hereinafter referred to by its cultivar name ‘Summer Glory’.

The new cultivar was derived from a controlled breeding program conducted by the Inventor at a nursery in Florida City, Fla. The overall purpose of the breeding program is to make new selections of Philodendron plants with unique foliage that are cold resistant and durable with a good growth rate in Florida. ‘Summer Glory’ is the product of a controlled cross made by the inventor in August 2016 between an unnamed hybrid Philodendron as the female parent (unpatented) and an unnamed Philodendron gloriosum as the male parent (unpatented). ‘Summer Glory’ was selected by the inventor as a single unique plant in Florida City, Fla. from amongst progeny plants derived from said cross.

The new cultivar was selected based on its distinctive coloration, durability, and relative freedom from pests as compared to other commercially available Philodendron cultivars. ‘Summer Glory’ was first reproduced asexually using in-vitro meristem tip culture in Apopka, Fla. in August 2020. Asexual propagation by in-vitro meristem tip culture of the new cultivar has shown that the unique features of the new cultivar are stable and reproduced true-to-type in successive generations.

Plant Breeder's Rights for this variety have not been applied for. ‘Summer Glory’ has not been made publicly available or sold anywhere in the world prior to the effective filing date of this application.

SUMMARY OF THE INVENTION

The new Philodendron cultivar has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, light intensity, water status, fertilizer rate and type, without, however, any variance in genotype.

The following are the most outstanding and distinguishing characteristics of this new Philodendron cultivar. The combination of these characteristics distinguishes ‘Summer Glory’ as a new and distinct variety of Philodendron:

• • 1. Unique reddish bronze colored foliage on young leaves;
  • 2. Foliage that turns a dark, shiny green as foliage matures;
  • 3. Durability; and
  • 4. Relative freedom from pests.

DESCRIPTION OF THE PHOTOGRAPHS

This new Philodendron cultivar is illustrated by the accompanying colored photographs which show the overall appearance and distinct characteristics of the plant. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of a 3-year-old plant grown in a 2-gallon container under 60 to 90 percent shade in a ploy covered greenhouse in Apopka, Fla. Colors in the photographs may differ slightly from the color values cited in the botanical description which accurately describes the colors of the new variety.

DESCRIPTION OF THE NEW VARIETY

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

The following observations and measurements describe plants grown under 60 to 90 percent shade in a poly covered greenhouse in Apopka, Fla. Detailed descriptions were taken in May 2021 from a 3-year-old plant grown in a 2-gallon container. Measurements and numerical values represent averages of typical plant types.

COMPARISON WITH PARENTAL VARIETIES

‘Summer Glory’ differs from the female parent Philodendron plant in that ‘Summer Glory’ has dramatically different and larger leaf shape and color with striking red colored cataphylls surrounding emerging leaves. ‘Summer Glory’ differs from the male parent Philodendron plant in that ‘Summer Glory’ is much more colorful and more robust.

COMPARISON WITH COMMERCIAL VARIETIES

When ‘Summer Glory’ is compared to the commercial Philodendron plant ‘Prince of Orange’ (expired U.S. Plant Pat. No. 06,797), the juvenile leaf color on the adaxial surface of ‘Summer Glory’ is reddish bronze, whereas the juvenile leaf color on the adaxial surface of ‘Prince of Orange’ is bright orange. Further, ‘Summer Glory’ has a cordate-saggitate leaf shape with veins colored purplish pink, whereas ‘Prince of Orange’ has a narrowly ovate leaf shape with veins colored pink. Additionally, the growth habit of ‘Summer Glory’ is upright to arching with a prominent main stem, whereas the growth habit of ‘Prince of Orange’ is compact with a very short to near absent main stem.
