Fountainbush (Russelia equisetiformis)
Discover the vibrant beauty of Fountainbush (Russelia equisetiformis), a deciduous shrub known for its cascading red, firecracker-like blooms.
Complete Plant Information
Overview
The Fountainbush, botanically known as Russelia equisetiformis, is a show-stopping tropical subshrub prized for its fountain-like cascade of bright red, tubular flowers. These blooms resemble small firecrackers, attracting desirable pollinators like hummingbirds throughout the growing season. As a fast-growing, woody perennial in tropical climates, it offers excellent trailing coverage and vibrant color.
This plant features distinctive, rush-like, four-angled stems, giving it an informal, airy texture reminiscent of horsetail. While it thrives as a perennial in warmer regions, gardeners in cooler areas often rely on Russelia equisetiformis as a spectacular annual feature plant. It performs best when situated where its cascading stems can truly spill over containers or walls.
For optimal performance, this species demands plenty of bright light and consistent moisture, though established plants show reasonable tolerance once settled. Its dramatic flowering habit and ability to thrive in full sun make the Fountainbush a high-impact choice for summer displays.

How to Grow
Plant Russelia equisetiformis where it receives full sun exposure for the most prolific flowering. This shrub prefers average, medium, well-drained soils but shows flexibility, even tolerating some dry soils once established. When planting containers or garden beds, ensure the location is sheltered from harsh, strong winds, which can damage the delicate, cascading stems.
Maintain medium soil moisture, especially during the peak growing season. While established plants can endure brief dry spells, consistent watering supports its continuous bloom schedule. If using in a pond periphery or water garden setting, the Fountainbush will readily accept moist soil conditions right at the damp edge.
For gardeners outside zones 9-11, treat Russelia equisetiformis as a container annual. In frost-prone areas, overwinter the plant indoors in a warm, sunny room where it may even continue blooming. Alternatively, you can force dormancy by heavily cutting back the stems and storing the pots cool, dark, and dry until spring. New stems emerging in spring can be refreshed by pruning back last year’s growth.
Cascading stems often naturally root where they touch moist ground, providing an easy propagation method. Simply lift these rooted sections to pot up new plants for the following season or to expand your display area.
Landscape Uses
The Fountainbush excels where vertical interest and trailing accents are desired. Its native growth habit makes it an excellent candidate for hanging baskets, where its woody stems spill gracefully over the edges, creating a living cascade of red flowers. In garden settings, sink containers to the rim near stone walls so the branches drape naturally, or place them at the edge of ponds and water features where the moist soil mimics its native habitat.
Because the stems of Russelia equisetiformis can be trained, tying them up against a trellis against a sunny wall offers a unique vertical screen effect different from its typical cascading form. As a container plant, the Fountainbush pairs wonderfully in mixed plantings, adding height and texture contrast to the bird garden or rock garden designs.
Since the blooms are highly attractive to hummingbirds, consider grouping the Fountainbush with other nectar-rich plants to create a dedicated wildlife area. Its bold red color demands attention, so use it as a focal point rather than burying it within a crowded border unless the aim is to have it spill out over pathways.

Noteworthy Characteristics
The vibrant tubular flowers of Russelia equisetiformis are often described as resembling firecrackers, blooming continuously from late spring until frost. It is considered synonymous with R. Juncea and is renowned for attracting curious hummingbirds to the garden. The combination of its rush-like, bright green foliage and intense red blooms gives the Fountainbush excellent visual impact.
Tolerances
Potential Problems
The Fountainbush is generally resilient, presenting “No serious insect or disease problems.” This excellent pest and disease resistance contributes significantly to its low maintenance profile. Monitor for general pests common to houseplants or greenhouse conditions during overwintering periods, ensuring adequate light and air circulation to prevent issues like spider mites or whiteflies if grown indoors in winter.

Conclusion
The Fountainbush (Russelia equisetiformis) provides unparalleled texture and season-long color with minimal fuss, making it a standout choice for containers and sunny borders where its trailing nature can be fully appreciated. Its attraction for hummingbirds adds significant ecological value to any garden space. Before planting, ensure your location falls within USDA Hardiness Zones 9-11 to maintain it outdoors, or plan for necessary overwintering indoors.
Companion Planting
When designing summer displays, pair the Fountainbush with plants that contrast its fine texture and bright red color. Trailing sweet potato vine (Ipomoea batatas) with dark purple or lime-green foliage creates an excellent textural foil below the rush-like stems of the Russelia equisetiformis. Succulents or drought-tolerant Mediterranean herbs that enjoy full sun also make good neighbors for potted displays, provided the Fountainbush’s moisture needs are also met nearby.
Wildlife Benefits
The tubular shape and bright red coloration of the Fountainbush flowers are specifically adapted to attract hummingbirds, who use their long bills to access the nectar deep within the blossoms. Including this plant in your landscape significantly enhances biodiversity by providing a reliable, high-energy food source for these fast-moving avian visitors during the entire summer season. Even minimal plantings of Russelia equisetiformis can turn a boring corner into a lively hotspot for bird activity.
