Pelargonium×domesticum cultivar Camelot.


The present invention comprises a new and distinct cultivar of Pelargonium×domesticum known by the varietal name ‘Camelot’ (Oglevee No. 234, Breeder No. 95-9-2). The cultivar was developed from an organized, scientifically designed breeding program conducted at the Department of Horticulture, The Pennsylvania State University, University Park, Pa. 16802. The breeding program was designed to create new regal Pelargonium genotypes with clear, bright flower colors, excellent propagation characteristics, compact growth habit, predictable and consistent flowering response and good post-production quality. The cross-pollination was done on Apr. 12, 1995. The pistillate parent of this new cultivar is ‘Duchess’ (U.S. Plant Pat. No. 8,074). The staminate parent (Breeder No. 93-11-5) was produced from prior selections developed at The Pennsylvania State University. The pedigree of the staminate parent includes the patented varieties ‘Splendor’ and ‘Fantasy’ (U.S. Plant Pat. Nos. 7,656 and 7,538, respectively) and other unpatented varieties and appears in FIG. 2. The new cultivar was first asexually reproduced on Sep. 9, 1996 by cuttings in University Park, Pa. The new cultivar has been trial and field tested at Connellsville, Pa. and has been found to retain its distinctive characteristics through successive propagations.

The cultivar, when grown in a glass greenhouse in Connellsville, Pa. using natural light and temperatures of 60° F. night and 68° F. day, has a response time of thirteen weeks from a rooted cutting to flowering in a 6 inch pot. The response time was determined on plants grown in soilless media employing constant fertilizer with 150-200 parts per million of nitrogen and potassium in full light.


FIG. 1 is a photographic drawing illustrating the new cultivar, with the color being as nearly true as is possible with color illustrations of this type; and

FIG. 2 is a flow chart of the pedigree of the staminate parent of the new cultivar.


The following detailed description sets forth the characteristics of the new cultivar. The data which defines these characteristics were collected from asexual reproductions carried out by Oglevee, Ltd. in Connellsville, Pa. The color readings were taken indoors under 200-220 foot candles of fluorescent cool white light. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London.

1. This new variety is similar in color to the current market variety ‘Jane’ (U.S. Plant Pat. No. 9,893) in color.

2. Cutting production is comparable to ‘Jane’.

3. Rooting speed is improved over ‘Jane’ by 7 days. Under optimal conditions rooting occurs in 14 days after sticking.

4. Plant habit is greatly improved as ‘Jane’ is very vegetative whereas ‘Camelot’ is not as vegetatively vigorous.

5. Amount of umbels and flowers/umbel is improved over ‘Jane’ by 30%.

6. Earlier to flower than ‘Jane’ by one to two weeks depending on conditions.

7. Flowering time is also improved over ‘Jane’ from 3-4 weeks to 6-8 weeks of continuous flowering.

8. Outdoor growth and flowering in central Pennsylvania is greatly improved over ‘Jane’.
