This evergreen sub-shrub is fast-growing, reaching its mature height in a year. Narrow leaves are 2 in (5 cm) long and densely cover the woody stems. Prune it quite a bit to keep it small and bushy.
This flowering shrub is easy to grow. Just give it lots of sunlight and you ll enjoy plenty of flowers. Unfortunately, this vigorous grower will become straggly over time. Plan on replacing Cuphea ignea after a couple years or so.
Sunlight: Bright light to full sun
Soil: Any good potting mix.
Water: Spring through fall, water thoroughly. Allow the soil to dry slightly between watering, but don t allow it to dry out completely. Keep the soil slightly drier in winter.
Temperature: Average room temperatures 60-75/16-24C. If you move your plant outdoors for the summer, don t worry; it can take the heat. It won t, however, tolerate temperatures below 50F/10C.
Fertilizer: Feed every 2 weeks spring through fall with a high-potassium liquid fertilizer diluted by half.
