[2] The Latin specific epithet equisetiformis implies the plant has a form "like/similar to Equisetum"—i.e., 'horsetail', 'horsetail rush/fern'—a genus which Russelia is only distantly related to (and which is not a true fern genera).

Russelia equisetiformis is a multi-branching plant with thin leaves and arching foliage that measure around 4–5 feet (1.2–1.5 m).

[2] R. equisetiformis is favoured by nectar-feeding birds & insects, due in-part to the trumpet-like, rather long flowers.

The firecracker plant is capable of ground in a diverse range of settings, This species is best grown as a sprawling bordering or cascading groundcover where it accentuates its natural tufting rush-like habit.

[2] In the UK, Russelia equisetiformis has earned the Royal Horticultural Society (RHS)'s Award of Garden Merit.
