ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention comprises a new and distinct cultivar of
Hibiscus rosa
-
sinensis
which was originated by crossing an unnamed, unpatented seedling (internal reference number 072493C) as seed parent, and the variety known as
Hibiscus rosa
-
sinensis
‘Sunny Delight’ (unpatented) as pollen parent. The varietal denomination of this new variety is
Hibiscus rosa
-
sinensis
‘Denise Yumi’.
To the best of my knowledge,
Hibiscus rosa
-
sinensis
‘Denise Yumi’ has never been patented in the United States and there is no prior pending United States Plant Patent Application or prior existing unpatented or unpatentable plant.
SUMMARY OF THE INVENTION
Among the novel characteristics possessed by the new variety which distinguish it from its parents and all other varieties of which I am aware are flowers of attractive coloration born on an upright and vigorous plant.
Asexual reproduction of the new variety by grafting as performed in Culver City, Calif., shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagation. Other known forms of asexual reproduction also may be used.
The following traits have been observed in the new variety ‘Denise Yumi’:
1. Cartwheel, overlapped single flower, ruffled, tufted, wavy edge.
2. Bright yellow body (near 9A-12A), white halo (near 155C), with a large dark magenta zone (near 57A-58A) which blends into dark red eye (near 45A-47A).
3. Vigorous, upright, medium growth habit.
4. Very good bloomer during warmer weather may (63° F./81° F.) through October (62° F./81° F.) in Southern California.
5. Leaf shape is somewhat cordate with acute apices and round smooth bases. Leaf margins are crenate.
6. Flower life is approximately three or more days on plant.
7. Endures temperatures of 30° F.
8. Propagation by cuttings.
This new variety ‘Denise Yumi’ bears a single flower on normal stems. The plant's flower tends to grow larger during the warmer months of July-August (low about 65° F., high about 86° F.) and slightly smaller between the cooler months of April and November (low about 55° F., high about 74° F.) in Culver City, Calif.
COMPARISON WITH OTHER VARIETIES
Compared to the new variety's seed parent, ‘Denise Yumi’, flower is smaller. ‘Denise Yumi’ has a flat cup-shaped flower, whereas, the seed parent's flower opens wider and petals are rolled and reflexed backward. The color of the seed parent is muddy white and not clear whereas ‘Denise Yumi’ color is clear. Compared to ‘Sunny Delight’s, ‘Denise Yumi’ has a different flower color and is hardier.
