Neoregelia is a genus of epiphytic and terrestrial bromeliads grown for the striking coloring of their lease and bracts when flowering. Neoregelia’s usually spiny-margined leaves are borne in rosettes; colorful bracts surround very small flowers at the center of the bracts.
Neoregelia may bloom at any time during the year. The changing color of the inner rosette or leaf tips signals the appearance of a flower. The compact heads of violet or blue flowers are not long-lasting, but the foliage color remains for several months.
Neoregelia is a genus of more than 100 species of evergreen, perennial bromeliads. Neoregelia is native to coastal scrub, woodlands, and rainforests in South America.

Where to plant Neoregelia
- Light indoors: Bright light, with direct winter sun, from eastern or western exposure. Foliage color is enhanced full light. Air circulation is important.
- Light outdoors: Plant in an open site with partial shade
- Soil indoors: Pot Neoreelia in an epiphytic bromeliad mix.
- Soil outdoors: Grow Neoregelia in gritty, leafy soil.
When to plant Neoregelia
- Set Neoregelia outdoors in a tropical or subtropical garden any time of the year.
Planting and spacing Neoregelia
- Space Neoregelia 16 to 24 inches (40-60cm) apart depending on the variety.
How to water and feed Neoregelia
- Water: Water Neoregelia freely during the growing period. Keep fresh water in the leaf cup. Keep the growing medium slightly moist. Mist occasionally. Optimal humidity is 45% to 60%
- Feeding: Apply a low nitrogen liquid fertilizer monthly during the growing period. Avoid oil-based products such as fish emulsion. Spray foliar fertilizer on the leaves, add to water in cup, or apply to growing medium after watering; never feed a dry plant.
Neoregelia care
- Neoregelia has no specific rest period; growth continues slowly throughout the year.
- Neoregelia dies within 2 years after flowering.
Growing Neoregelia as a houseplant
- Neoregelia carolinae and N. x marmorata are often grown as houseplants.
- Neoregelia need bright to direct light, an average temperature, and medium to high humidity.
- The potting medium can be kept relatively dry and the water cup in the center of the rosette should be filled with fresh water.
- Fertilizer can be applied once a month throughout the year.
Neoregelia pests and diseases
- Neoregelia is susceptible to scale insects and mealybugs.
- Bacterial soft rot and leaf spot and a variety of fungal leaf spots can occur.
Neoregelia propagation
- Sow Neoregelia seed in warm soil in spring.
- Separate offsets in spring or summer.
