Latest Future Plants V.O.F. Patents:
The present invention relates to a new and distinct cultivar of Astilbe plant, botanically known as Astilbe chinensis, and hereinafter referred to by the cultivar name ‘Vision in Pink’.
The new cultivar is a product of a planned breeding program conducted by the Inventor in Noorden, The Netherlands. The objective of the breeding program was to develop new Astilbes with pink-colored flowers.
The new cultivar originated from a cross made by the Inventor in 1997 of the Astilbe chinensis cultivar ‘Kremhilde’, not patented, as the male or pollen parent, with the Astilbe chinensis cultivar ‘Superba’, not patented, as the female or seed parent. The cultivar ‘Vision in Pink’ was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Noorden, The Netherlands.
Asexual propagation of the new cultivar by divisions at Noorden, The Netherlands, has shown the the unique features of this new Astilbe are stable and reproduced true to type in successive generations.SUMMARY OF THE INVENTION
Plants of the cultivar ‘Vision in Pink’ have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, daylength, and fertility level without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Visions in Pink’. These characteristics in combination distinguish ‘Vision in Pink’ as a new and distinct cultivar:
1. Upright plant habit.
2. Rapid growth rate.
3. Dark green leaves.
4. Very freely and continuous flowering.
5. Bright pink flowers.
Compared to plants of the purple-flowered cultivar ‘Vision’ (not patented), plants of the new Astilbe have pink flowers and are about 10 cm taller.BRIEF DESCRIPTION OF THE PHOTOGRAPHS
