This invention relates to a new and distinct selection of Mandevilla×amabilis (Hort. Bach.) Dress., reputed to be a hybrid of Mandevilla speldens×Mandevilla crassinoda and a member of the Apocynaceae family. Mandevilla×amabilis cultivar Monite was the result of a sport observed on a Mandevilla×amabilis cultivar Alice du Pont (not patented) plant in April 1997. This novelty of a flower within a flower which botanically are the petaloids within the throat of the flower, was what the selection was based on. My discovery was made at Sperling Landscape & Supply, 24460 Calabalas Road, Calabalas, Calif. My new selection has been asexually reproduced at 18331 East Foothill Boulevard, Azusa, Calif. exclusively by tissue culture since the discovery. Had this sport not been discovered and propagated, it may have been lost to mankind. It is unlikely this particular select and favourable attribute of this plant could be conveyed to progeny through sexual reproduction in the next generation. Through extensive tissue culture propagation it has been established that the novel exceptional characteristics of this plant are stable and reliably passed on to clonal specimens through asexual reproduction.
Mandevilla×amabilis cv. Monite was selected for its showy cluster of pink petaloids within the flower throat appearing as a pink flower within a larger pale pink flower. Prior to my discovery, only Mandevilla×amabilis with either single flowers such as Mandevilla×amabilis c.v. Alice du Pont (not patented), c.v. Monte U.S. Plant Pat. No. 10,329, and c.v. White Delite U.S. Plant Pat. No. 8,479 along with the recently introduced double c.v. Rita Marie Green U.S. Plant Pat. No. 11,787 were widely grown. None of these cultivars display showy petaloids that remain within the throat of the flower. My selection cultivar Monite will tolerate a 30° F. temperature, which is equivalent to U.S.D.A. hardiness zone ten, but does require frost protection.
The accompanying illustrations FIG. 1 and FIG. 2 exhibit flowers and buds of a specimen of cultivar Monite reproduced in color as true as reasonably possible with illustrations of this type, the color fidelity may be slightly lighter in color.
Below is a detailed description of a 2 year old plant of Mandevilla×amabilis cultivar Monite. The color terminology is from The Royal Horticultural Color Charts. Descriptions are from containerized plants grown in temperatures ranging from 35° F. to 105° F. in Azusa, Calif.
