A distinct cultivar of Hypericum plant named `Bosapri`, characterized by its early flowering, plants flower about 13 weeks after planting; long stem length, typically about 70 cm; large bright red berries; and dark green leaves.

Description

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hypericum plant, botanically known as Hypericum androsaemum, commonly referred to as Saint John's Wort, commercially used as a cut flower, and hereinafter referred to by the cultivar name `Bosapri`, and also known by the trade name Prince Flair and also known by the trade name Prince Flair. To date, the new Hypericum has not been noted to have any medicinal value. To date, the new Hypericum has not been noted to have any medicinal value.

The new Hypericum is a product of a planned breeding program conducted by the Inventor in Rijnsburg, The Netherlands. The objective of the breeding program was to develop cut Hypericum varieties with attractive berry color, early flowering, long flowering stem length, and large berry size. The new cultivar originated from a cross made by the Inventor in 1984 of two proprietary seedlings. The proprietary selection code number 83 was the female, or seed, parent, and the proprietary selection code number 71 was the male, or pollen, parent.

The cultivar Bosapri was discovered and selected by the Inventor in August, 1985 as a flowering plant within the progeny of the stated cross in a controlled environment in Rijnsburg, The Netherlands.

Asexual propagation of the new Hypericum by cuttings taken at Rijnsburg, The Netherlands, has shown that the unique features of this new Hypericum plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of `Bosapri`. These characteristics in combination distinguish the new Hypericum plant as a new and distinct cultivar:

1. Early flowering; plants flower about 13 weeks after planting.

2. Long stem length; typically about 70 cm.

3. Large bright red berries.

4. Dark green leaves.

The new Hypericum can be compared to its sibling cultivar `Dual Flair`, disclosed in U.S. Plant Pat. No. 10,979. In side-by-side comparisons conducted in Rijnsburg, The Netherlands, plants of the new Hypericum are taller, have smaller leaves, and have redder berries than plants of the cultivar `Dual Flair`.

The new Hypericum can also be compared to its sibling cultivar `Bosakin`, disclosed in U.S. Plant Pat. No. 10,994. In side-by-side comparisons conducted in Rijnsburg, The Netherlands, plants of the new Hypericum flower earlier, have smaller leaves, and have smaller and redder berries than plants of the cultivar `Bosakin`.

Plants of the new Hypericum have not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light or fertility level, without, however, any variance in genotype.
