ABSTRACT:
Botanical classification: Hosta.
Variety denomination: ‘Thunderbolt’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of plaintain lily that is grown for its vigorous growth, white flowers and thick, furrowed, variegated leaves. The new cultivar is known botanically as Hosta and will be referred to hereinafter by the cultivar name ‘Thunderbolt’.
‘Thunderbolt’ was discovered by the inventor in a cultivated area of Hickory, N.C. in 1998 as a sport of the parent plant
Hosta sieboldiana
‘Elegans’. ‘Thunderbolt’ was selected, by the inventor, for its unique variegated leaves with wide blue-green margins and narrow cream-white centers. As a young plant the leaves are blue-green with golden centers and as the plant matures the leaf centers become cream-white and the margins darken. The plant most similar to ‘Thunderbolt’ are the parent plant
Hosta sieboldiana
‘Elegans’ (unpatented) and Hosta ‘Dream Weaver’ (unpatented). ‘Thunderbolt’ differs from ‘Elegans’ in its bluer, thicker leaves and its variegation that exhibits a wider green margin and narrow cream-white center. ‘Thunderbolt’ also grows more vigorously than the parent plant ‘Elegans’, which is slow-growing. ‘Thunderbolt’ is suitable for planting in full shade or partial shade. ‘Thunderbolt’ differs from ‘Dream weaver’ in that it has leaves with a wider margin and narrower cream-white center. The leaves of ‘Thunderbolt’ are more deeply furrowed than those of ‘Dream Weaver’.
Asexual reproduction of the new cultivar was first accomplished by the inventor in a cultivated area of Hickory, N.C. in 1998 using tip cuttings. The characteristics of the new cultivar have been determined 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 ‘Thunderbolt’. These traits in combination distinguish the new cultivar from all other commercial varieties known to the inventor. ‘Thunderbolt’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic and cultural conditions.
1. Hosta ‘Thunderbolt’ exhibits large, furrowed leaves.
2. The leaves of Hosta ‘Thunderbolt’ are bluer and thicker than the parent plant.
3. Hosta ‘Thunderbolt’ exhibits leaves with blue-green margins and golden centers in spring that turn to cream-white centers as the plant matures.
