ABSTRACT:
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.

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.
