Botanical Name: Russelia equisetiformis
Firecracker plant is a weeping shrub bursting with long sprays of orange-red flowers that lend it its name. Other common names include coral plant and coral fountain plant.
The narrow, tubular flowers are about 1 in (2.5 cm) long and cover the plant from late spring till fall. Actually, it can flower any time of year, given enough warmth and light. You'll get the most blooms by putting it in full sun. Moving it outdoors for the summer is ideal. It's attractive to passersby as well as to butterflies and hummingbirds.
Show it off. Display your firecracker plant in a large hanging basket and allow it to cascade, showing off the fine-textured foliage covered with bright flower clusters. Give it some space, too. This spectacular, many-branching shrub can spread as wide as it is tall.
Prune it back. By pruning off stems that have already flowered, you'll get more flowers! Cut off spent flower stems at the base anytime. To keep your plant a manageable size, prune it back hard in early spring.
Bring it in. This shrub is an evergreen perennial that's frost-tender. Unless you live in a year-round warm climate, expect to overwinter it indoors. Keep it in a warm, sunny location. Reduce watering because growth will slow down in winter.
Height: 3-6 ft (90 cm - 1.8 m) tall; trails to 6 ft (1.8 m)

Soil: Any good potting mix with a little added perlite or sand for quick drainage.
Fertilizer: Feed every 2 weeks spring through fall with a balanced liquid fertilizer diluted by half. In winter, feed monthly.
