About Freesia 'Yellow Passion'
Freesia 'Yellow Passion' · also called Yellow Passion freesia, golden freesia · flowering
Freesia 'Yellow Passion' is a tender corm freesia bearing strongly fragrant golden-yellow blooms on arching, one-sided spikes. Excellent for cutting, pots and the cool greenhouse, it wants full sun and gritty, free-draining soil. Cool nights trigger flowering; after bloom the leaves recharge the corm before a dry summer rest.
Preferred mix: Light, sandy, free-draining loam or gritty bulb compost, slightly acidic to neutral
Watch for — Corm rot from wet conditions: Overwatering or wet dormant storage rots corms. Use free-draining compost and keep corms dry after the foliage dies down.
Why freesia 'yellow passion' needs this mix
Freesia 'Yellow Passion' 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 freesia 'yellow passion': 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 freesia 'yellow passion' struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A thin, hungry or sandy mix gives freesia 'yellow passion' 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 freesia 'yellow passion' 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 freesia 'yellow passion'?
Most flowering plants, including freesia 'yellow passion', 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 freesia 'yellow passion' 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 freesia 'yellow passion' covers the timing and technique step by step.
