About Peregrina

Jatropha integerrima · also called Peregrina, Spicy Jatropha · flowering

Peregrina is a vigorous, evergreen tropical shrub or small tree from Cuba, prized for its near-continuous display of vivid crimson-red flowers and attractive, variably shaped leaves. It is a top performer in warm-climate gardens and a standout container plant. Full sun maximises flowering; it is frost-tender but recovers quickly from brief light frost damage.

Mature size: 3–4.5 m tall and 3–4.5 m wide in outdoor frost-free conditions; 90–150 cm in containers

How to tell peregrina needs repotting

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

Thick roots out of the drainage holes, or circling the surface and lifting the plant.
The pot dries out unusually fast and peregrina wilts between waterings it used to shrug off.
The plant is visibly top-heavy and tips over easily.
Stalled growth and small new leaves over a full season — though with a big specimen, top-dressing is often the better first response before a full 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 peregrina

Every 2–3 years; top-dress in the in-between years. Peregrina's growth habit — multi-trunked, rounded to vase-shaped evergreen shrub or small tree with a symmetrical open crown. leaves are variably shaped on the same plant — entire, 3-lobed, or fiddle-shaped (pandurate) — and mid- to dark-green. produces abundant flat-topped clusters of brilliant crimson-red (occasionally pink) flowers almost year-round in warm climates. — sets the pace.

What size pot to step peregrina up to

Move up exactly one pot size. A heavy peregrina dropped into a vastly bigger pot sits in a reservoir of wet soil its roots cannot reach, which rots them and destabilises the plant. In the years between repots, lift off and replace the top 3–5 cm of soil (top-dressing) instead — it refreshes nutrients without the shock of a full repot.

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 peregrina

Early spring, just as new growth restarts, is the ideal window for peregrina. 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 peregrina

Consider top-dressing first. If peregrina is not badly root-bound, scrape off and replace the top 3–5 cm of soil instead — far less shock for a big plant that hates moving.
Get help and one size up. For a full repot, choose a pot just one size larger. A heavy plant needs two people and a stable, free-draining pot.
Ease it out on its side. Lay the plant down, slide the pot off, and gently loosen the outer roots. Do not bare-root a mature specimen.
Repot at the same depth. Add fresh well-draining loam, sand, or clay beneath and around the rootball, keeping the original soil line. Firm it so the trunk is stable and upright.
Water and leave it put. Water thoroughly, then leave peregrina in the same spot and light — moving and repotting at once is what makes it drop leaves.

Aftercare

Leave peregrina in exactly the same spot and light it was in before — moving and repotting at the same time is what makes a big specimen drop leaves. Water it in well, then let the top of the soil dry before watering again so the larger volume of fresh soil does not stay sodden. Do not fertilise for about 4 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for peregrina

Peregrina wants well-draining loam, sand, or clay. Adaptable to a wide range of soil types including clay, sand, and loam, provided drainage is adequate. Works in slightly acidic to slightly alkaline pH (5.5–7.5). In containers, use a quality all-purpose potting mix with added perlite (20–30%) to improve drainage. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting peregrina — frequently asked questions

How often should you repot peregrina?

Every 2–3 years; top-dress in the in-between years for peregrina. Fully repot peregrina only every 2–3 years; in the in-between years just top-dress the top 3–5 cm of soil. Step up one pot size in spring with well-draining loam, sand, or clay. It is heavy and hates being moved, and a vastly oversized pot holds water against the roots and rots them.

What size pot does peregrina need?

When is the best time of year to repot peregrina?

Should you top-dress or fully repot peregrina?

For a big, heavy peregrina, top-dressing — replacing the top 3–5 cm of soil — is the gentler option most years, with a full repot only every 2–3 years. A mature specimen sulks and drops leaves when fully repotted, so do it as rarely as the roots allow.

Should you fertilise peregrina after repotting?

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