OVERVIEW
About This Plant
Erythrinas (coral trees) can be a striking way to add pollinator-friendly blooms at tree height. Start by choosing the right plant for your situation: the genus Erythrina includes many species, and their size and cold tolerance can differ a lot. If you’re gardening in a place with cold winters, a large container can be a practical option so the plant can be protected when needed.
For best results, prioritize sun and drainage. A bright, open spot usually supports better flowering, and well-drained soil helps prevent root problems. During the first season, water regularly to help the roots settle in; after that, adjust watering to your soil and weather rather than keeping the ground constantly wet.
When the tree blooms, it can become a “stop here” sign for nectar-seeking visitors. Keep the area around the tree simple and safe for pollinators by avoiding pesticides, especially while flowers are open. If pests show up, try non-chemical steps first—like rinsing with water, removing affected parts, or improving plant health with better placement and watering.
To make your garden more helpful overall, pair a coral tree with a mix of flowering plants below it so something is blooming across the seasons. That layered approach—flowers at ground level and blossoms above—can make even a small yard feel more like a welcoming habitat.
Best role for pollinators
Warm-climate gardens, courtyards, and large containers where a small tree can be protected if needed

SUMMARY
If You Remember Three Things
A quick scan of what they do, what they need, and the best first step.
What they need
Sun and good drainage are common needs; choose a species that matches your space and winter conditions.
One best action
Pick a locally suitable Erythrina species (or grow in a container) and place it in a sunny, well-drained spot.
IMPACT
Why Plant This?
A flowering tree can add both beauty and useful nectar resources, helping your garden offer more than just ground-level blooms.
Many coral trees are named for their coral-like flower color and clustered blooms.
Key Impacts
What it Supports
- Big, bright blooms can help pollinators notice your garden from a distance.
- A flowering tree adds height and variety, which can make a yard feel more “habitat-like.”
- Trees can support a layered garden design: groundcovers and flowers below, blossoms above.
RECOGNITION
Identification Guide
Coral trees can look different depending on the species, but a few traits are common across the genus.
Leaves
Often compound leaves with three leaflets; leaf size and texture vary by species.
Flowers
Showy clusters of tubular or pea-like flowers, commonly red to orange; bloom size and shape vary by species.
Fruits
Pods may form after flowering; seeds can be noticeable and bead-like in some species.
LOCATION
Where It Grows
Native environments and the best spots to place it in your landscape.
Habitats
- Warm, open woodlands and edges (varies by species)
- Seasonally dry areas (varies by species)
Where it is often used
- Pollinator focal tree in a sunny yard
- Courtyard or patio specimen (especially in a large container)
- Seasonal color accent near seating areas (where you can watch visitors)
SEASONALITY
When It Blooms
Notes on bloom windows and how this plant helps pollinators across the seasons.
Bloom window
Bloom timing depends on the Erythrina species and your local conditions.
Bloom Season Role: A bold, high-nectar bloom that can act as a seasonal “beacon” plant.
Seasonal benefits
- Adds a strong burst of color
- Can provide nectar when in bloom
- Creates a clear “destination” plant for pollinators
REQUIREMENTS
What It Needs
The right mix of sun, soil, and space for healthy growth.
Sun exposure
Give as much sun as you can for best flowering, with some afternoon shade in very hot, exposed sites.
Soil type
Well-drained soil is key. If your soil stays wet, improve drainage or use a raised bed/container.
Moisture needs
Water regularly while establishing, then adjust based on your soil and weather. Let the top layer of soil dry slightly between waterings rather than keeping it constantly wet.
Planting method
Plant where it has room to grow and where falling flowers/pods won’t be a problem on walkways. In cooler regions, consider a container so it can be moved to protection when needed.
Mulching tips
Use a light mulch layer to reduce weeds and help soil stay evenly moist, keeping mulch away from the trunk.
GARDENING GUIDE
How to Grow It
Simple steps to plant, prune, and maintain healthy trees without pesticides.
Planting tips
- Choose a species or cultivar suited to your space and local winter conditions (or plan for container growing).
- Pick a sunny spot with good drainage; avoid low areas where water collects.
- Dig a hole as deep as the root ball and wider than it; set the plant so the top of the root ball is level with the soil surface.
- Backfill, water in well, and add a light mulch ring (not touching the trunk).
- Stake only if needed for stability, and remove supports once the tree is established.
Seasonal care
- Water consistently during the first growing season; after that, water based on soil dryness rather than a strict schedule.
- Prune lightly to remove dead or crossing branches; avoid heavy pruning right before the usual bloom period.
- Watch for stress signs (wilting, leaf drop) and adjust watering and sun exposure if the site is too harsh.
- Keep the area under the tree free of weeds and avoid damaging the trunk with lawn equipment.
What not to do
- Planting in soil that stays wet after rain.
- Overwatering once the tree is established.
- Pruning at the wrong time and losing blooms.
- Spraying pesticides when flowers are open and pollinators are active.
Pairings
Best Pairings for Season-Long Bloom
Pairing ideas to keep pollinators fed throughout the growing season.
Early Bloom
- Native spring wildflowers suited to your area
- Early-blooming shrubs that match your site conditions
Mid-Season Bloom
- Sun-loving, pollinator-friendly perennials
- Herbs that flower (let some basil, oregano, or chives bloom)
Late-Season Bloom
- Late-season nectar plants (choose local, non-invasive options)
- Seed-producing flowers for birds later in the year
Because “coral tree” can refer to many different Erythrina species, check the exact species name before planting—especially if winter cold is a concern or if you’re choosing a plant for a small space.
