How to Grow Shrimp Plant

Shrimp Plant

Justicia brandegeeana

shrub

The shrimp plant is a tropical flowering shrub known for its distinctive curved, shrimp-like inflorescences that are typically brick-red, orange, or yellow in color. The tubular white or purple flowers emerge from the colorful bracts, creating a striking two-toned display that attracts hummingbirds and butterflies. It's an excellent choice for containers, hanging baskets, and indoor cultivation.

Growing Conditions

☀️

Sun: Bright, indirect light; tolerates 3-4 hours of direct morning sun; can adapt to partial shade but blooms more prolifically with more light

💧

Water: Keep soil consistently moist but not waterlogged during growing season; reduce watering in winter; prefers humidity; mist regularly to maintain moisture around foliage

📏

Spacing: 18 inches

📅

Days to maturity: 60-90 days to first flowering from establishment

🌱

Planting depth: Same depth as container; plant shallow

Soil

Type: Well-draining, fertile loamy soil

pH: 6.0-7.0

Amendments:

Peat moss Compost Perlite or sand for drainage

Growth Stages

Establishment

2-4 weeks

Young plant is adjusting to conditions with tender new growth and developing root system

Keep soil consistently moist, avoid direct intense sun, maintain humidity, use bright indirect light, fertilize monthly with balanced fertilizer

Vegetative Growth

4-8 weeks

Plant develops bushy foliage with numerous stems and bright green leaves; minimal flowering

Pinch back growing tips to encourage branching; fertilize every 2-3 weeks with balanced or slightly higher nitrogen fertilizer; maintain warm temperatures (65-75°F); increase light exposure

Pre-flowering

2-4 weeks

Plant reaches mature size with dense foliage; flower buds begin forming on branch tips

Reduce pinching, switch to fertilizer higher in phosphorus to promote flowering, maintain consistent watering and humidity, ensure adequate light

Flowering

8-12 weeks (continuous in ideal conditions)

Distinctive shrimp-like flower spikes emerge in reds, oranges, or yellows with small white or purple tubular flowers protruding from bracts

Continue watering consistently, deadhead spent bracts to encourage more blooms, maintain warm conditions, provide bright light, fertilize every 2-3 weeks with bloom-promoting fertilizer

Maintenance & Pruning

Ongoing

Mature plant continues blooming; may become leggy or overgrown without regular maintenance

Prune in spring to shape and encourage branching; cut back by 1/3 to 1/2 to maintain compact form; remove any diseased or dead wood; can be cut back hard and will regenerate

Avoid planting near:

Very dry-tolerant succulents that need less water Plants requiring full intense sun only Cold-hardy plants in tropical settings

Common Pests

Increase humidity and mist regularly; spray with neem oil or insecticidal soap every 7 days for 3 weeks; isolate heavily infested plants
Dab with rubbing alcohol on a cotton swab; spray with insecticidal soap; use neem oil; introduce parasitic wasps for biological control
Scrape off manually; spray with horticultural oil or neem oil; apply insecticidal soap; repeated applications may be necessary
Use yellow sticky traps; spray with insecticidal soap or neem oil; vacuum off adults; maintain good air circulation
Ensure well-draining soil; allow soil to dry slightly between waterings; remove affected plant from pot, trim rotted roots, repot in fresh soil; improve air circulation

Harvest Tips

Shrimp plants are ornamental and not harvested for food; however, flower spikes can be cut for fresh floral arrangements when fully developed, typically lasting 2-3 weeks in water. Deadheading spent bracts throughout the flowering season encourages continuous blooming.

Fun Facts

🌱 The shrimp plant gets its common name from the remarkable resemblance of its flower spike to a cooked shrimp, complete with a curved shape and overlapping bracts that resemble the shrimp's segments.
🌱 The actual flowers are the small white or purple tubes that emerge from the bracts—most people assume the colorful curved part is the flower, but those are specialized leaves called bracts that protect and display the true flowers.
🌱 Shrimp plants are native to Mexico and Central America and were named scientifically by Thomas Brandegee; they thrive in warm, humid conditions similar to their tropical and subtropical origins.
