Sinningia leucotricha x cardinalis

  1. Feature table

I have grown S. leucotricha x cardinalis seed from the Gesneriad Hybridizers Association Seed Fund.  Most of the resulting plants were S. leucotricha, but one was definitely a hybrid, with reddish flowers and cardinalis-type foliage which was nonetheless somewhat hairy.  This is shown in the picture.

In crossing S. cardinalis and S. leucotricha, one would be hoping for S. leucotricha foliage and S. cardinalis flowers.  Unfortunately, what one gets is more like S. cardinalis foliage and S. leucotricha flowers.

I have selfed this plant, and also back-crossed it to S. leucotricha (including the "Max Dekking" form).  These seedlings have flowers of the leucotricha type, with foliage about halfway between this hybrid and leucotricha.  Given Vincent Parsons's experience (see the douglasii x leucotricha page), this may be a long project!  On the other hand, given how long these species have been in cultivation, if cardinalis flowers on leucotricha foliage were easy, it would already have been done.




Feature table for Sinningia leucotricha x cardinalis

Plant Description

Growth Determinate, like S. leucotricha
Habit Stems upright with 2-4 leaf pairs
Leaves Green, with some silvery hairs, about halfway between leucotricha and cardinalis
Dormancy Stems fully deciduous.  Dormancy is obligate.

Flowering

Inflorescence terminal cluster like S. leucotricha, but also axillary cymes in the lower leaf axils, like S. cardinalis.
Season Blooms spring-summer, about the same time as S. leucotricha
Flower Salmon pink to orange-red, tubular, slightly larger than S. leucotricha's, but without S. cardinalis's galea, which must therefore be recessive

Horticultural aspects

From seed About three years to bloom, under my conditions
Hardiness Has tolerated 30F (-1C) in my yard
Recommended? Not a bad plant, mostly interesting for hybridizing potential

Botany

Taxonomic group Both parents are in the Dircaea clade.
