Fireworks Globe Amaranth

Fireworks Globe Amaranth (Gomphrena globosa 'Fireworks')

Fireworks Globe Amaranth is a heat-proof summer annual that delivers tall, airy stems topped with neon color for months. The blooms hold their look in sun and humidity, keeping beds and containers bright when other flowers fade. It is an easy way to add vertical lift, pollinator activity, and cut-flower stems without a high-maintenance routine. If you want long-season color that thrives in hot weather, this plant is built for it.

Distinctive Features

This standout gomphrena produces unique tufted flower clusters in hot pink with bright yellow tips, creating a firework-like effect on long, wiry stems. Bloom begins in early summer and continues until frost, with flowers that stay attractive and hold color well. The habit is upright and open, taller than many globe amaranth types, which makes it excellent for adding height without visual heaviness. Once established, it is notably tolerant of heat and short dry spells.

Growing Conditions

• Sun: Full sun for best flowering and strongest stems.
• Soil: Well-drained soil, and it tolerates average soils as long as drainage is good.
• Water: Medium moisture to establish, then low to medium water, allowing slight drying between waterings.
• USDA Zones: 9 to 11 as a tender perennial, typically grown as an annual elsewhere.
• Mature Size: About 36 to 48 inches tall and 12 to 24 inches wide.
• Notable Traits: Excellent heat and drought tolerance once established, strong pollinator appeal, and good performance as a cut flower.

Ideal Uses

• Focal Point: Use Fireworks Globe Amaranth as a focal point at the back of a sunny border where the tall stems and neon blooms can carry the view all summer.
• Cut Flower Gardens: Harvest stems for fresh arrangements, and the blooms also work well for drying.
• Sunny Borders: Adds vertical texture and long-season color without a bulky footprint.
• Containers: Makes a bold statement in large pots where height and continuous bloom are needed.
• Pollinator Plantings: Supports bees and butterflies through the long summer bloom window.

Low Maintenance Care

• Watering: Water regularly during the first few weeks, then shift to deeper, less frequent watering once rooted in.
• Deadheading: Deadheading is optional, but removing spent blooms can keep the plant looking especially tidy.
• Feeding: Avoid heavy fertilizing, since overly rich soil can reduce flowering and make stems less sturdy.
• Spacing: Provide airflow and sun exposure to keep growth strong and flowering consistent.
• Season Timing: Plant after frost risk has passed and soils have warmed for the fastest start.
