Streptocarpus 'Sirius' 12cm

A true breeding breakthrough, Streptocarpus ‘Sirius’ is a stunning, fully double variety that produces an abundance of large, richly coloured blooms. Each flower opens wide to reveal inky purple petals beautifully veined over a soft, pale yellow base, creating a striking contrast.

This exceptional variety is early to flower, fast growing, and incredibly free-flowering, making it a standout addition to any collection. Without question, one of our finest recent introductions.

Shortlisted for Chelsea Plant of the Year 2026, highlighting its outstanding performance and unique beauty.
