ABSTRACT:
Botanical classification/cultivar designation:
Spiraea fritschiana
cultivar Wilma.
BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of
Spiraea
plant, botanically known as
Spiraea fritschiana
, and hereinafter referred to by the cultivar name Wilma.
The new
Spiraea
originated from a cross-pollination during the spring of 1995 of two unidentified selections of
Spiraea fritschiana
, not patented. The cultivar Wilma was discovered and selected by the Inventor as a single plant within the progeny of the stated cross-pollination in a controlled environment in East Lansing, Mich. The selection of the new
Spiraea
was based on its vibrant pink-colored flowers.
Asexual reproduction of the new cultivar by softwood cuttings taken at Grand Haven, Mich., since spring, 1997, has shown that the unique features of this new
Spiraea
are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the cultivar Wilma have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature 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 ‘Wilma’. These characteristics in combination distinguish ‘Wilma’ as a new and distinct cultivar:
1. Upright and rounded plant habit.
2. Freely branching growth habit.
3. Red-colored young leaves.
4. Freely flowering habit.
5. Vibrant pink-colored flowers.
6. Excellent garden performance.
Plants of the new
Spiraea
are most similar to the parent selections and differ from plants of parent selections and other known selections of
Spiraea fritschiana
in the following characteristics:
1. Plants of the new
Spiraea
are more freely branching than other known selections of
Spiraea fritschiana.
2. Young leaves of plants of the new
Spiraea
are more red in color than young leaves of other known selections of
Spiraea fritschiana.
3. Plants of the new
Spiraea
have larger inflorescences with more flowers per inflorescence than other known selections of
Spiraea fritschiana.
4. Plants of the new
Spiraea
have pink-colored flowers whereas other known selections of
Spiraea fritschiana
have white-colored flowers.
