Raising hybrid Streptocarpus/Cape Primrose from seed is a great indoor project for gardeners and plant lovers.

These seeds are collected in autumn 2023 winter 2024 from our hand-pollinated plants -- including some of the plants in the photos and many others. Flowers from 3 to 6 cm across are carried on wire-thin stems rising from loose rosettes of velvet-soft, arching leaves. Colours range from white  and yellow through pale rose and lavender to deep violet, midnight blue, and rich cerise. Some flowers have ornate markings; others have boldly coloured contrasting centers.

These seeds can be shipped safely at any time of year. We have tested seeds stored outdoors for several days at temperatures colder than -20C and they germinated just fine.

We test our seeds every 3-4 months and add new seeds all the time. Our routine tests produce better than 80% germination.

We sometimes post photos of plants raised form our seeds on the blog Primrose Fields: Scenes for a Garden in Edmonton, Canada.

Seeds sprout 2-3 weeks after sowing, and first flower buds appear 4-6 months later. Display your potted plants outdoors in summer, in a cool, shady spot, or keep them indoors in a window or under lights. A well-tended plant at its peak, usually beginning in early summer, will cascade with blossoms for many weeks, and can go on flowering, at a lesser rate, through autumn and into the darkest days of winter. Streps are easy, rewarding houseplants all year round. We have them sitting in windows on every side of the house, where they flourish in any natural light.

The seeds are very small and a little tricky to handle, but each packet is sure to contain more than the stated number. We also provide a page of instructions to help get your project started.
