Summary

Firebush (Hamelia patens) is a root-hardy tropical that is native to southern Florida, Central America and South America. As a result, we consider Lime Sizzler to be a nativar, or cultivar of a southeastern native plant. Its best attribute is the amazing variegated chartreuse and light green foliage with red veining. The blooms come in clusters of orange-red tubular flowers that are about 2 inches long and attract hummingbirds throughout the summer. Make sure to plant Lime Sizzler in full sun; if planted in the shade, the colors will be less vibrant. Firebush is a natural host plant for gulf fritillary butterflies and will help sustain your butterfly and pollinator gardens. Lime Sizzler has a pop of color that will draw your eye each and every time you step foot into the garden.

Requirements

  • Thrives in a wide variety of soils from pH of 5.5 to 7.0.
  • Does best in full sun; however, will grow in partial shade. Best to get 8-plus hours of direct sun.
  • Likes well-drained soils but can handle more moist areas.

Growth Habit

  • Grows back from the roots each spring and will grow
  • 3 to 5 feet tall and 3 feet wide most years.
  • Space 3 to 4 feet apart to allow for yearly regrowth.
  • Recommended for hardiness zones 8B to 11, but Lime Sizzler can be used as a color-popping summer annual in colder regions. May be treated as an annual in zone 8A.
  • Lime Sizzler grows slower than other species of firebush in the landscape and is less cold hardy.

Care and Maintenance

  • Ensure proper moisture, especially during drought periods. If possible, drip irrigation is recommended.
  • Apply 2 inches of mulch around the base to prevent soil from drying out and to ensure proper root health.
  • A balanced controlled-release fertilizer in early to mid-spring is recommended.
  • Lime Sizzler can be pruned to shape; however, this is not necessary as the plant holds very true to shape and trimming can reduce blooms.
  • Cut dead foliage to the ground after freeze each year for regrowth the following spring.
  • Some reversion has been seen in long term plantings. Simply remove any dark green growth early in the season.
  • Lime Sizzler will continue to bloom throughout the warm season.
  • No major pests have been identified for Lime Sizzler in Louisiana
