ABSTRACT:
CROSS-REFERENCES TO RELATED APPLICATIONS
The application for this new invention will be co-pending with two other applications corresponding to plants that were derived from the same breeding program. They are entitled: Verbena Plant Named ‘Dosmau (application Ser. No. 09/590,358’ and Verbena Plant Named ‘Dospi’ (application Ser. No. 09/590,359). However, ‘Dosblu’, ‘Dosmau’ and ‘Dospi’ are not known to be genetically related since the parents chosen for each cross were unique.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of
Verbena peruviana
, a perennial that is grown as a bedding and container plant. The new invention will be referred to hereinafter by the cultivar name ‘Dosblu’.
The new Verbena is a selection from a breeding program conducted by the inventor in Skeerpoort, Magaliesberg, South Africa. The objective of the program is to select new cultivars of
Verbena peruviana
that have an improved habit combined with unique flower colors. ‘Dosblu’ and its co-pending varieties are especially characterized by their flower colors with prominent white eyes and their dense, spreading habit. ‘Dosblu’ was a seedling from a hand pollinated cross made between Verbena ‘Sky Blue’ (unpatented) and Verbena ‘Dark Blue’ (unpatented). The crossing and selection was done by the inventor in Skeerpoort, Magaliesberg, South Africa. The initial cross was made in February, 1997 and ‘Dosblu’ was selected in July, 1997. ‘Dosblu’ differs from its parents in that it has a more dense and well-branched habit than either parent. ‘Dosblu’ has a prominent white eye, whereas Verbena ‘Sky Blue’ has no white eye, and Verbena ‘Dark Blue’ has a small white eye. Additionally, the flower color of Verbena ‘Sky Blue’ is a very pale blue. The combined characteristics of the new invention, ‘Dosblu’, are unique. ‘Dosblu’ differs from another Verbena on the market known as Verbena ‘Violet’. Verbena ‘Violet’ has a more open habit in the center of the plant when grown in a container and has flowers that are more violet colored with no eye. ‘Dosblu’ differs from the ‘Dosmau’ and ‘Dospi’ in that its flowers are a deep violet-blue as opposed to mauve and pink, respectively..
Asexual reproduction of the new cultivar was first accomplished by taking terminal cuttings in Skeerpoort, Magiesberg, South Africa in August, 1997 by the inventor. The characteristics of this cultivar have been determined to be stable and are reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish this cultivar from other commercial varieties.
1. The flower color of ‘Dosblu’ is a violet-blue with a distinct white eye, 0.6-0.7 mm in diameter. No other Verbena known to the inventor with this flower color has a distinct white eye.
2. The color of the flower of ‘Dosblu’ fades as the flower ages giving a multi colored effect to the blossom.
3. The habit of ‘Dosblu’ is mounded and then spreading.
4. ‘Dosblu’ plants are well branched with short internodes to give the plant a dense appearance. Many verbenas of the trailing types do not have this dense coverage of foliage.
