The Boldest Red-Orange Flowering Shrub for Phoenix Heat

Bells of Fire (Tecoma 'Bells of Fire') is a showstopper — a compact, drought-tolerant shrub that pumps out clusters of bright red-to-orange tubular flowers from spring through fall. Hummingbirds can't resist it, and neither can Phoenix homeowners looking for maximum color with minimum water. Growing 4–6 feet tall, this Tecoma hybrid thrives in the brutal summer heat that wilts most flowering plants. Whether you're adding a splash of color to a Scottsdale poolside, brightening a Mesa border, or creating a hummingbird haven in Chandler — Bells of Fire delivers non-stop blooms all season long.

Bells of Fire Uses in Phoenix Landscapes

Colorful Border & Mass Planting

Plant Bells of Fire in groups of 3–5 along fence lines, property borders, or garden beds for a wall of red-orange blooms all summer. Space 3–4 feet apart for mass plantings. A 20-foot border needs about 6 plants. The vibrant flowers create a tropical feel that stands out against desert-toned homes and gravel landscapes.

Hummingbird & Pollinator Garden

The bright tubular flowers are irresistible to hummingbirds, making Bells of Fire the anchor plant for any Phoenix pollinator garden. Pair it with Chuparosa, Desert Milkweed, and Penstemon for a year-round hummingbird habitat. The non-stop blooming from spring through fall keeps the birds coming back all season.

Pool-Friendly Color

Bells of Fire's compact form, non-invasive roots, and minimal leaf litter make it an excellent choice near pools and patios. The vivid red-orange flowers add tropical color to outdoor living areas without creating a maintenance headache. Perfect for adding life to poolside beds in Scottsdale and Tempe.

Low-Water Color Accent

Most flowering shrubs that produce this much color need heavy watering. Bells of Fire breaks that rule — once established, it thrives on minimal irrigation while still pumping out flowers all season. Use it wherever you want bold color without the water bill.

Best Time to Plant Bells of Fire in Phoenix

Spring (March–April) is the ideal planting window for Bells of Fire, as warm soil and lengthening days kick-start rapid growth. Fall (October–November) is also excellent. Avoid planting in peak summer if possible, though established plants handle extreme heat without issue.

How to Plant Bells of Fire

1. Dig wide, not deep — 2–3x the root ball width, same depth as the container.
2. Check for caliche — break through any hardpan layer for proper drainage.
3. Backfill with native soil — a light 20% compost blend is fine but not required.
4. Spacing — 3–4 feet apart for mass plantings and hedges; 5 feet for standalone specimens.
5. Water basin — build a 3–4 inch ring of soil around the planting hole to direct water to roots.
6. Mulch — 2–3 inches of gravel or bark mulch to retain moisture and keep roots cool.
