Sinningia reitzii is a fine species from southern Brazil.  It normally has perennial stems persisting from one year to the next, even though it also makes a substantial tuber.  It flowers from the leaf axils, on peduncles usually bearing many flowers.  The flowers are red, sometimes shaded toward magenta.

The seedlings of this species are particularly attractive.  The leaves are dark green with a herringbone white pattern down the midrib.  The backs of the leaves are dark red.

This pattern usually fades in the mature plant.  Depending on how much light the plant is getting, the leafbacks may lose most of their red, but will retain the color along the midribs, as in the picture above.

This picture of Sinningia reitzii shows the red flowers, the red veins on the leafbacks, and the peduncle which distinguishes it from S. sp. "Black Hill".

Comparison to S. "Black Hill"

See the table for a comparison between S. reitzii and S. sp. "Black Hill".


As can be seen in a picture, the tuber is multi-lobed.


Leaf back

Sinningia reitzii has intense red or maroon leafbacks, especially when young or grown in relatively low light.


Sinningia reitzii is an excellent parent for hybridization.  To its offspring it usually imparts attractive dark leaves, tolerance of a variety of environments and culture, and most importantly, a long blooming season (usually late summer and autumn, but sometimes starting in early summer), generally longer than that of S. reitzii itself.
