Sinningia 'Altamont Cascade'
(Sinningia eumorpha 'Saltão' x bragae)

At the 2006 Gesneriad Society convention, Bill Price gave me a tuber of his cross between S. eumorpha 'Saltão' and S. bragae, the latter species then being known as Sinningia sp. "Ibitioca".  The hybrid first bloomed for me in May 2007, at the same time as S. bragae.

What a wonderful plant!

The flowers look a lot like those of S. bragae: purple, campanulate (bell-shaped), with a yellow guide in the throat.  The habit is derived from S. eumorpha: an erect stem with flowerstalks in the leaf axils.  This makes for a tidier plant than the Ibitioca parent, which often sprawls.  The hybrid also has (for me, in 2007) four flowers per axil, up from eumorpha's one (or occasionally two).

In November 2009, Bill informed me that he was registering the plant under the name 'Altamont Cascade', Altamont being the neighborhood in which he lives.


Front Comparison

The picture on the left shows the front view of two flowers.  The hybrid flower is on top, with the Sinningia sp. "Ibitioca" flower on the bottom.  The hybrid flower has a wide yellow strip in the corolla throat, inherited from S. eumorpha.  The purple of the "Ibitioca" flower is just a bit denser.

The picture on the right shows the flowers from the side, again with the hybrid on top.  The flowers are essentially the same size, with the hybrid having the "slipper" shape from S. eumorpha.

Both parents have big leaves, and the cross has really big leaves.  One leaf blade (not counting the petiole) is 24 cm [9.5 inches] long.
