ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention comprises a new and distinctive Lobelia plant, hereinafter referred to by the cultivar name Periwinkle Blue. This new cultivar was the result of a unique interspecific cross between
Lobelia erinus
and
Lobelia valida
. More specifically, the breeding program which resulted in the production of the new cultivar was carried out at Arroyo Grande, Calif. in 1997. The female or seed parent of Periwinkle Blue was the
Lobelia erinus
plant from the Palace Series named ‘Blue With Eye’ (unpatented) which exhibits dark purple-blue flowers with white centers or “eyes” and has a semi-trailing habit. The male or pollen parent of Periwinkle Blue was an unnamed
Lobelia valida
plant which exhibits lavender-blue flowers and an upright habit. The resulting seed was collected and germinated. From the flowering progeny, a single plant was selected and initially designated BPF-100, and now given the cultivar name ‘Periwinkle Blue’. The parentage of the new cultivar can be summarized as follows:
Lobelia erinus×Lobelia valida
Asexual reproduction of the new cultivar by terminal cuttings taken during 1998 and 1999 at Arroyo Grande, Calif., U.S.A. has demonstrated that the characteristics of the new cultivar as herein described are firmly fixed and are retained through successive generations of such asexual propagation.
SUMMARY OF INVENTION
It was found that the cultivar of the present invention:
(a) exhibits initial upright growth followed by a semi-trailing habit,
(b) forms sky-blue flowers with white “eyes”,
(c) exhibits a vigorous growth habit,
(d) is extremely floriferous.
The ‘Periwinkle Blue’ cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length.
When the new cultivar of the present invention is compared to the Lobelia plant ‘Azuro’ (U.S. Plant Pat. No. 10,758) it is found that the new cultivar exhibits a more vigorous, trailing growth habit and lighter blue flower color.
