Firebush Plant Guide: How to Grow and Care for a Firebush

Firebush (Hamelia patens) is a large, semi-woody perennial shrub native to South Florida and the US tropics with flame-colored tubular flowers and a high tolerance for intense heat and sun. Also referred to as a scarlet bush or a hummingbird bush, the plant has yellow and orange flower buds that attract pollinators like butterflies, hummingbirds, and songbirds from spring through the first frost in the fall.

The firebush has multiple trunks with smooth gray bark and light to dark green leaves that are covered with fine hairs. In warm climates, the shrubs can grow quickly, up to 15 feet tall, including several feet in its first growing season alone. The plants are closely related to the Mexican firebush, which is indigenous to Mexico and Central America.

A firebush plant is great for adding color and density around your patio or deck, especially in areas with hot summers, where other plants may wither. This drought-tolerant plant is popular in places like Florida, where it is naturalizing. Firebush plants work well as casual hedges, in mixed borders (garden beds that contain different types of plants), or as a stand-alone shrub.

You can also use firebushes against blank walls or fencing or as a backdrop to lower-growing plants. To do so, you may want to plant your firebush in rows to create a dense hedge effect. Check the plant’s growth regularly, pruning it to maintain your desired shape. You can also prune the firebush around the strongest trunk to shape it into a small tree.

Firebush is popular because of how easy it is to care for once it reaches established maturity. Here’s what to consider if you’re growing a firebush:

• Fertilizing: Although fertilizer’s not necessary, you may want to add one for the nutrients it can offer your plant. For the best possible flowers, use a fertilizer designed to boost blossoming potential and follow the recommended product instructions.
• Heat: These plants thrive best in USDA Hardiness Zones eight through 11. These plants require warmth and do best in southern climates rather than northern climates or shady gardens. They are tolerant of drought and heat. If exposed to temperatures below 40°F for extended periods of time, the leaves may turn red or purple.
• Propagation: The firebush is readily available from native nurseries, though they can also be propagated by either seeds or cuttings.
• Pruning: While you can prune as needed to keep the plant to a reasonable size, you should take care to avoid over-pruning since pruning too hard or too frequently can limit your plant’s flower production. In the spring, cut back any damage from the winter to ensure new growth for the season.
• Seasonality: Planting your firebush in late spring or early summer will give it the best chance of survival and growth.
• Soil: You can plant firebushes in any soil type, though the soil should drain well since the plant can’t tolerate soggy roots.
• Sunlight: These plants require warmth and should be planted in an area with full sun for best growth, though it may tolerate part shade. However, partial shade may result in a lesser bloom.
• Watering: Water a firebush regularly until it is established, drenching the plant every couple of weeks in its first few seasons. Before you water it again, allow the top few inches of soil to dry out. These plants are also moderately tolerant of salt spray, which may be helpful if you are planting in a coastal area.
