About Tiger Flower
Tigridia pavonia · also called Tiger flower, Mexican shell flower · flowering
Tigridia pavonia is a showy bulbous perennial from Mexico and Central America, producing exotic, large (10–15 cm), three-petalled flowers in vivid reds, pinks, oranges, yellows, and white — each heavily spotted at the centre — from midsummer through to early autumn. Individual flowers last only one day, but each stem carries multiple buds that open in succession over several weeks. It needs full sun, fertile well-drained soil, and warm summers to perform at its best; in cooler climates the bulbs should be lifted before the first frost. No toxicity to cats or dogs has been formally reported, but ingestion is still best avoided.
Preferred mix: Fertile, well-drained loamy or sandy soil, pH 5.5–7.5
Watch for — Iris borer (Macronoctua onusta): In North America, iris borer larvae can tunnel into Tigridia corms, causing wilting and rotting. Inspect corms at lifting, discard any with tunnels or soft spots, and consider a preventive imidacloprid soil drench where infestations are a known problem.
Why tiger flower needs this mix
Tiger Flower 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 tiger flower: 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 tiger flower struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A thin, hungry or sandy mix gives tiger flower 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 tiger flower 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 tiger flower?
Most flowering plants, including tiger flower, 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 tiger flower 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 tiger flower covers the timing and technique step by step.

What is the best soil mix for tiger flower?
3 parts good loam or quality peat-free compost : 1 part well-rotted compost or leaf mould : 1 part grit or perlite. Flowering is expensive for tiger flower: producing buds, blooms and seed draws heavily on nutrients and steady moisture, so the soil has to keep delivering all season.
Can I use normal potting soil for tiger flower?
