Sinningia cardinalis is a beautiful plant with a round basal caudex and velvety, bright-green leaves that sprout from it in spring on pale green stems up to 12 inches (30 cm) tall. It has a period of dormancy after growth and flowering. Flowers are brilliant orange-red, hooded, up to 2 inches (5 cm) long and can appear multiple times from late winter to mid summer.
USDA hardiness zones 11a to 11b: from 40 °F (+4.4 °C) to 45 °F (+7.2 °C).
How to Grow and Care
Sinningias grow from tubers, so there is seasonality to them. When the plant is actively growing, keep it lightly moist. When the foliage dies back, just mist the soil regularly to keep the tubers from drying out too much. Start your normal watering when new leaves start to show. As with most plants, Sinningias can survive a short drought, but they do not recover from drowning. Use tepid water when watering. Nobody enjoys a cold shower. Water the soil, not the plant. Sinningias are prone to crown rot and gray mold which happens when the leaves stay wet. Do not let the plant sit in water, it must be well drained.
These are shade plants. They have the same light requirements as an African Violet. Morning or soft late afternoon light is best. That means an East, shaded West, or North-facing window. By all means, avoid direct sun during the harsh "skin cancer" hours of the day.
