About Strawberry Fields gomphrena
Gomphrena haageana 'Strawberry Fields' · also called Strawberry Fields gomphrena, Strawberry Fields globe amaranth · flowering
A bold, vibrant annual bearing conical, strawberry-red flower-heads on tall, upright 60–75 cm stems. Gomphrena haageana 'Strawberry Fields' is prized for its exceptional heat tolerance, long-lasting colour from summer to frost, and superb vase life both fresh and dried. A standout cut flower and border accent for hot, sunny gardens.
Preferred mix: Well-drained loam or sandy loam, average fertility
Watch for — Root and stem rot from poor drainage: The greatest threat to 'Strawberry Fields' is waterlogged soil. Plant in raised beds or mounded rows if drainage is imperfect; do not overwater, particularly in cooler UK summers.
Why strawberry fields gomphrena needs this mix
Strawberry Fields gomphrena flowers hardest in a rich but free-draining loam — fed enough to fuel the display, open enough that the roots never waterlog.
- Flowering is expensive for strawberry fields gomphrena: producing buds, blooms and seed draws heavily on nutrients and steady moisture, so the soil has to keep delivering all season.
- A loam-based mix holds nutrients and water far more evenly than a light peat mix, which means a longer, more reliable flowering period.
- It still needs sharp drainage — most flowering plants resent cold, wet feet far more than they resent being a little lean.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons strawberry fields gomphrena struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A thin, hungry or sandy mix gives strawberry fields gomphrena weak growth and few, short-lived flowers — it simply runs out of fuel.
- A heavy, badly drained soil rots the roots or crown, often over a wet winter, and you lose the plant before it ever flowers again.
- Over-rich, high-nitrogen mixes can push lush leaf at the expense of flowers — balance, not excess, is the aim.
Either starving strawberry fields gomphrena in a thin mix or drowning it in a heavy, badly drained one. It wants the rich-but-free-draining middle, plus a flowering (higher-potassium) feed in season.
pH — does it matter for strawberry fields gomphrena?
Most flowering plants, including strawberry fields gomphrena, do well around pH 6.0-7.0. A cheap soil test is worth it outdoors; one notable exception is any acid-lover (such as some hydrangeas), where pH directly changes flower colour.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
DIY mix vs a bagged one
A quality bagged compost works for strawberry fields gomphrena in pots if you add grit and a flowering feed. In beds, improving the existing soil with compost and ensuring drainage beats any bag.
Drainage and the pot
Free drainage protects the roots and especially the crown over winter — raised beds, grit in the planting hole and never a waterlogged spot. Containers must have a clear drainage hole.
For perennials, refresh the top layer and feed each spring rather than disturbing the roots; for container displays, start with fresh rich mix each season. When the time comes, our repotting guide for strawberry fields gomphrena covers the timing and technique step by step.
