The flowers of this unique Cape primrose are large and lavish, opening wide to reveal inky purple petals intricately veined over a soft, pale yellow throat, giving a striking contrast that draws the eye straight in. Its fully double form adds extra depth and texture, making each bloom feel generous and full-bodied rather than flat. Expect plenty of them too, as this is a fast-growing cultivated variety that doesn’t hold back once it gets going.
Compact yet impactful, Streptocarpus ‘Sirius’ works brilliantly on a bright windowsill out of full sun, in a conservatory, or as a standout in a sheltered patio display during warmer months. It prefers bright, indirect light watering with a long flowering season and reliable performance. Supplied in a white glazed ceramic pot, which offers an immediate and attractive way to display it in your home.
We’re proud to support our British growers, and having been raised by one of our trusted UK nurseries, this indoor plant has a low carbon footprint, which makes it perfect for an eco-friendly collection or gift.

How to care for Streptocarpus Sirius:
Throughout the growing season, keep them quite well watered, but as they are sensitive to overwatering, allow the compost to get a little dry in between; during this time they should also be fed with a high potash fertiliser. Remove spent flowers as they fade and trim back any old leaves that are past their best. Overwinter on a south or west-facing windowsill and water less often. Repot each spring into a slightly larger, shallow pot filled with fibre-based compost. They can also be used as summer bedding - grow in fertile, humus-rich, moist but well-drained soil in partial shade.
