USPP36127P2 - Begonia plant named ‘Summer Storm’ - Google Patents

Abstract

A new and distinct cultivar of Begonia plant named ‘Summer Storm’ is disclosed, characterized by large, colorful, distinctively patterned leaves having a dark green background and distinct light yellow-green splotches. Plants are tolerant of heat and humidity and observed winter hardy to zone 7b without protection. Plant is robust, vigorous, easy to grow and easy to propagate, observed resistant to typical diseases and pests and not attractive to deer. The new cultivar is a Begonia, typically suited for garden and ornamental container use.

Description

Latin name of the genus and species: Begonia rex.

Variety denomination: ‘Summer Storm’.

BACKGROUND OF THE INVENTION

The new cultivar is a product of a planned breeding program. The new variety originated from the crossing of the seed parent, Begonia rex ‘Taconite’, unpatented, with the pollen parent, Begonia rex ‘Eugene’, unpatented, by the inventor during September of 2014. The crossing was made in Washington DC in the inventor's garden.

‘Summer Storm’ was selected by the inventor, in October of 2015 in Washington DC in the inventor's garden.

After selection of the new cultivar, asexual reproduction of ‘Summer Storm’ was first performed October of 2015 in Washington DC in the inventor's garden by leaf cuttings. ‘Summer Storm’ has since produced several generations and has shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘Summer Storm’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Summer Storm.’ These characteristics in combination distinguish ‘Summer Storm’ as a new and distinct Begonia cultivar:

• 1. Plant has large, colorful, distinctively patterned leaves having a dark green background and distinct light yellow-green splotches.
• 2. Plant is tolerant of heat and humidity.
• 3. Plant is observed winter hardy to zone 7b without protection.
• 4. Plant is robust, vigorous, easy to grow and easy to propagate.
• 5. Plant is resistant to pests (mealybugs such as Planococcus citri, scale Saissetia coffeae) and diseases (fungal diseases such as Erysiphe, Botrytis cinerea and bacterial leaf spot Xanthomonas begonia), and is not attractive to deer.

PARENTAL COMPARISON

Plants of the new cultivar ‘Summer Storm’ are similar to the seed parent in most horticultural characteristics. However, plants of ‘Summer Storm’ differ in the following:

• • 1. The new variety is taller growing, with a more upright stem
  • 2. The new variety has more deeply serrated leaves
  • 3. The new variety has a distinct silver pattern on the leaf; ‘Taconite’ has a uniformly dark leaf with indistinct markings.

Plants of the new cultivar ‘Summer Storm’ are similar to the pollen parent in most horticultural characteristics. However, plants of ‘Summer Storm’ differ in the following:

• 1. The new variety is larger growing overall.
• 2. The new variety has bigger leaves.
• 3. The new variety has a more spreading growth habit.
• 4. The new variety has a more well-defined leaf pattern with fewer but larger, more distinct silver markings (‘Eugene’ has numerous, smaller silver markings that are less distinct).

COMMERCIAL COMPARISON

Plants of the new cultivar ‘Summer Storm’ are similar to the commercial variety ‘Sterling Moon’ U.S. Plant Pat. No. 33,164 in most horticultural characteristics. However, ‘Summer Storm’ differs in the following:

• 1. The new variety has foliage with a daker green background than this comparator.
• 2. The new variety is more tolerant of heat and humidity than this comparator.
• 3. The new variety is more root hardy than this comparator.
• 4. The new variety has a longer leaf size than this comparator.
• 5. Plants of the new variety grow about 50% wider than plants of this comparator.

Plants of the new cultivar ‘Summer Storm’ are similar to the commercial variety ‘Fireworks’, unpatented, in most horticultural characteristics. However, ‘Summer Storm’ differs in the following:

• 1. The new variety is more cold hardy than ‘Fireworks’.
• 2. The new variety blooms more reliably and has a larger flower size than ‘Fireworks’.
• 3. Plants of the new variety are taller and more upright than plants of ‘Fireworks’.
• 4. The new variety has sturdier foliage which is less prone to damage (physical damage such as wind and rain) than ‘Fireworks’.
