The product of several generations of focused hybridization, S. 'Tomorrow' exhibits the upright peloric-flowered form characteristic of modern hybrids of Sinningia speciosa, albeit with much smaller flowers. Peloric flowered forms of S. cardinalis (here and here) are ancestral to this breakthrough cultivar. S. 'Tomorrow' is a cross between another peloric hybrid, S. 'Bewitched', and the pale yellow species S. conspicua.
