S. ‘Blue Streaker’ was one of the very first of the compact Streptocarpus. It was produced by Lyndon Lyon from the species S. erubescens and S. cyanandrus, along with hybrids of S. rexii. While attractive and floriferous, this plant was not particularly easy to grow well. Most of the more recent compact cultivars are not derived from crosses to the very compact species, which were the source of the cultivation difficulties.
