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.

Mature size: 60–90 cm tall in flower, 15–20 cm spread per clump

Watch for — Botrytis on stored bulbs: Tigridia corms stored over winter in damp conditions are prone to botrytis (grey mould). After lifting, cure corms in a warm, airy spot for one to two weeks, dust lightly with sulphur powder, and store in dry compost or paper bags at 7–10°C.

How to tell tiger flower needs repotting

Repotting on a calendar is less reliable than reading the plant. For tiger flower, watch for these signs:

Roots spiralling thickly out of the drainage holes or pushing the whole plant up out of the pot.
The pot is so packed that water runs straight through in seconds and barely wets the soil.
It has split a plastic pot, or the rootball is a solid mass with almost no soil left when you slide it out.
Growth and (for tiger flower) flowering have clearly stalled despite good light and feeding — but remember this plant likes being snug, so a little crowding alone is not a reason to repot.

For the underlying biology of a pot-bound root system and why it stalls a plant, see our guide to spotting and fixing a root-bound plant.

How often to repot tiger flower

Only every 2–4 years, when genuinely crowded. Tiger Flower is one of the plants that genuinely prefers a snug pot — it grows and flowers better with its roots a little restricted, so resist the urge to repot it on schedule. Cormous perennial with sword-shaped, pleated leaves forming fans similar to an iris; flowering stems are upright, branching, and reach 60–90 cm tall, each bearing multiple short-lived but spectacular blooms..

What size pot to step tiger flower up to

Go up only one pot size — roughly 2–3 cm (about an inch) wider in diameter, no more. Tiger Flower positively prefers a snug pot: it flowers and grows better when the roots are a little restricted. The single biggest repotting mistake here is over-potting — dropping tiger flower into a pot two or three sizes up. All that surplus soil holds water the small root system cannot use, stays cold and wet, and rots the roots within weeks. When in doubt, choose the smaller pot.

Not sure of the exact diameter? Our pot size calculator takes the current pot and root spread and tells you the right next size — it deliberately recommends a single step up, never a big jump.

The best time of year to repot tiger flower

Early spring, just as new growth restarts, is the ideal window for tiger flower. The plant is moving into its strongest growth phase and re-roots into fresh soil quickly. Avoid repotting in winter dormancy or, for flowering plants, while it is in bud or bloom — recovery is slowest then and you risk dropping the flowers.

Step-by-step: repotting tiger flower

Confirm it actually needs it. Slide tiger flower out and check the roots. Only continue if it is genuinely packed — this plant prefers a snug pot, so if there is still soil and room, put it straight back.
Pick a pot only one size up. Choose a pot just 2–3 cm wider with good drainage. Resist anything bigger; over-potting is the main killer here.
Ease it out gently. Water lightly the day before, then tip tiger flower out, supporting the base. Tease the outer roots free only enough to stop them circling.
Repot at the same depth. Add a layer of fresh fertile, well-drained loamy or sandy soil, ph 5.5–7.5, set the plant so the soil line sits exactly where it did before, and backfill around the sides, firming lightly.
Settle it in. Water once to settle the soil, then let it sit. Hold off on more water until the top of the soil dries — fresh soil around a small root system stays wet for a while.

Aftercare

Because the new soil holds more water than the old crammed rootball did, ease right back on watering — let the top of the soil dry before you water tiger flower again, or you will rot the roots in the very pot you just moved it to. Keep it out of harsh direct sun for a fortnight. Do not fertilise for about 4 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for tiger flower

Tiger Flower wants fertile, well-drained loamy or sandy soil, ph 5.5–7.5. Plant bulbs 8–10 cm deep in spring after the last frost in well-prepared, organically enriched, free-draining soil; avoid heavy clay, which stays too wet and cold for reliable establishment. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting tiger flower — frequently asked questions

How often should you repot tiger flower?

Only every 2–4 years, when genuinely crowded for tiger flower. Only repot tiger flower every 2–4 years, and only when it is genuinely root-bound — it flowers and grows best slightly crowded. Step up just one pot size in spring using fertile, well-drained loamy or sandy soil, ph 5.5–7.5. The key mistake is over-potting: a too-big pot stays wet and rots the roots.

What size pot does tiger flower need?

When is the best time of year to repot tiger flower?

Does tiger flower like to be root-bound?

Yes — tiger flower genuinely flowers and grows best when slightly pot-bound, so do not rush to repot it. The mistake to avoid is over-potting into a much larger pot: the excess soil stays wet, the roots cannot use it, and the plant rots. Only repot every few years and only one snug size up.

Should you fertilise tiger flower after repotting?

Not immediately. Wait about 4 weeks after repotting tiger flower. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
