About Gomphrena globosa 'QIS Pink'
Gomphrena globosa 'QIS Pink' · also called QIS Pink Globe Amaranth, Cut-flower Globe Amaranth Pink · flowering
'QIS Pink' (Quality In Series) is a globe amaranth bred for cut flowers, with extra-long, sturdy stems carrying papery, clover-like pink clover-heads. This heat-loving, drought-tolerant warm-season annual blooms non-stop from summer to frost, attracts pollinators, and holds its colour superbly as a fresh or dried everlasting flower.
Preferred mix: Average, well-drained soil; tolerates poor and sandy ground
Watch for — Root rot from overwatering: Wet, heavy soil rots the roots of this drought-lover; plant in free-draining ground and let it dry between waterings.
Why gomphrena globosa 'qis pink' needs this mix
Gomphrena globosa 'QIS Pink' 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 gomphrena globosa 'qis pink': 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 gomphrena globosa 'qis pink' struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A thin, hungry or sandy mix gives gomphrena globosa 'qis pink' 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 gomphrena globosa 'qis pink' 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 gomphrena globosa 'qis pink'?
Most flowering plants, including gomphrena globosa 'qis pink', 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 gomphrena globosa 'qis pink' 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 gomphrena globosa 'qis pink' covers the timing and technique step by step.
