Popular as a houseplant, Streptocarpus 'Polka-Dot Red' (Cape Primrose) is a compact, evergreen perennial with small, velvety, wrinkled, strappy leaves and large magnificent flowers produced over several months. Borne on short upright stems, the blossoms feature delicate deep blossom-pink veins that make a stark contrast to the solid white background. This Streptocarpus is a very floriferous selection blooming continuously for over 8 months. Use Cape Primrose as a flowering indoor plant or in containers on a shaded deck or patio.
- Grows up to 10-12 in. tall and wide (25-30 cm)
- Performs best in bright filtered light with shade from hot sun in fertile, moist, humus-rich well-drained soil. Water freely allowing the soil to dry out between waterings. Feed fortnightly with a high-potassium fertilizer.
- Keep an eye out for glasshouse leafhoppers, mealybugs, thrips, vine weevil and tarsonemid mite. Overwatering may cause rotting at the base of the plant.
- Deadhead regularly and remove damaged leaves. Mature plants should be cut back after flowering. The plant will remain dormant for up to three months after pruning. Cut back on watering and do not fertilize during this period.
- Propagate by division of clumps or by leaf cuttings in spring or summer.
