Abstract
A Streptocarpus plant named Mercury characterized by the combined characteristics of relatively large and violet colored flowers with white netting which are long-lasting, non-shattering, and continuously bloom under low light conditions of winter and high temperatures of summer.
Description
The present invention relates to a new and distinct cultivar of Streptocarpus plant, botanically known as Streptocarpus×hybridus, and known by the cultivar name Mercury. ‘Mercury’ was developed through controlled breeding by crossing Mikkelsen Seedling No. 92-167-6 (seed parent) (unpatented) with Mikkelsen Seedling No. 92-150-2 (pollen parent) (unpatented). The seed and pollen parents are proprietary breeding lines which have not been sold or made publicly available in this country.
Asexual reproduction of leaf cuttings has shown that the unique features of this new Streptocarpus are stabilized and are reproduced true to type in successive propagations. The plant was propagated in Ashtabula, Ohio.
The following characteristics distinguish the new Streptocarpus from other cultivated Streptocarpus of this type known to the inventor. The characteristics are described with comparative reference to the cultivars Demeter (unpatented) and Sirius (unpatented).
1. ‘Mercury’ has flowers colored Violet Group 87A netted with White Group 155C while ‘Demeter’ has a more purple-violet color of Violet Group 88B with heavier White Group 155C netting. ‘Sirius’ has deep purple color of Violet Group 86A with netting of Violet Group 86D.
2. ‘Mercury’ has a 50 to 55 mm flower diameter which is similar to ‘Demeter’ and larger than ‘Sirius’ (45 to 50 mm).
3. ‘Mercury’ has a white eye which is intermediate in diameter between ‘Demeter’ which has a very large eye and ‘Sirius’ which has no eye.
4. ‘Mercury’ has a red-purple cast to the midrib of the leaf and veins on young leaves while ‘Demeter’ and ‘Sirius’ each have midribs and veins on underside of leaves.
5. ‘Mercury’ has more serration on the edge of petals than either of ‘Demeter’ and ‘Sirius’.
6. ‘Mercury’ has a red-purple cast to the ovary which similar to ‘Demeter’ while ‘Sirius’ has a green ovary.
7. ‘Mercury’ has leaves 15 to 18 cm long and 5 to 6 cm wide with ‘Demeter’ having leaves 15 to 18 cm long and 4.5 and 5 cm wide and ‘Sirius’ having shorter leaves at 12 to 15 cm long and 5 to 6 cm wide.
The accompanying colored photographs illustrate the overall appearance of the cultivar taken as a face view of the plant and showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.
FIG. 1 is an overall view of the plant; and
FIG. 2 is a close-up view of the flowers.
The following is a detailed description of my new cultivar, based on plants produced in greenhouses in Lompoc, Calif. during the winter season of the year. Plants were grown in 10 cm pots and measurements were taken 12 weeks after rooted cuttings were planted. Height measurements were taken from the soil line of the container. The plants were grown at 16° C. night temperatures 2500-3500 foot candles of light and 200 ppm nitrogen, 75 ppm potassium and 200 ppm phosphorous nutritional levels, with trace elements added. Habit of growth, foliage coloration, size of leaves and flower size will be greatly influenced by nutritional and environmental conditions.
Color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.

Disease resistance: No disease problems seen to date.
1. ‘Mercury’ has numerous short leaves in a rosette instead of a few large leaves that characterize many older Streptocarpus cultivars. This results in a very floriferous plant with flowers clustered in middle of green foliage making an attractive 15 cm plant.
2. Flowers are long-lasting, non-shattering and leaves are small and pliable making this cultivar easy to ship.
3. ‘Mercury’ has shown the ability to flower year round during higher temperatures of summer and lower light levels of winter under greenhouse conditions.
4. ‘Mercury’ does not foliar spot when watered with 10° C. water and tolerates fairly high light levels (2500 foot candles) without the leaves bronzing.
