How to Grow Alexandria Laurel

Calophyllum inophyllum · Zones 11-12

Alexandria Laurel is a tree, a long-term addition to the landscape. It's hardy across USDA zones 11 through 12 and handles dry spells once it's established. Its flowers are a moderate draw for honeybees and native bees, even though the fruit is the prize.

What Alexandria Laurel is

Alexandria Laurel grows as a perennial and reaches around 40 feet at maturity.

How to grow Alexandria Laurel

Alexandria Laurel grows in USDA zones 11 through 12. Alexandria Laurel does best in full sun — at least 6 hours of direct sun a day — and soil from pH 5 to 8, on consistently moist ground.

  1. Plant it right

    Set alexandria laurel in full sun with consistently moist soil. Many fruit trees need a second variety nearby to pollinate — check before you plant just one.

  2. Match the soil

    Alexandria Laurel prefers pH 5 to 8 (FAO ECOCROP). A quick soil test from your local Extension lab tells you whether to add lime or sulfur to land in band.

  3. Water while it roots in

    Water deeply while alexandria laurel establishes, letting the soil dry between soakings; once its roots are in, it rides out dry spells on its own.

  4. Be patient, then harvest

    Prune annually while the tree establishes; fruit trees reward patience with years of harvest. Local Extension guides publish per-cultivar bearing-age tables.

Where Alexandria Laurel thrives

Alexandria Laurel is hardy across USDA zones 11 through 12. Zone is only the starting point, though: the soil pH, drainage, and frost dates on your specific land decide how well it actually does.

A USDA zone is a 10°F band of average annual extreme winter minimum, so zones 11–12 spans average winter lows from 40°F to 60°F (USDA PHZM 2023). Across the 50 states and DC, that band covers none outright but splits 3 down the middle — and which side of that line your land sits on changes the answer.

Where Alexandria Laurel stands, state by state

Alexandria Laurel is rated for zones 11–12 — a cold floor USDA puts at 40 to 50°F. Across the 50 states and DC, 0 sit fully inside that band, the line runs through 3 more, and 48 sit outside it — and inside every split state, the same line runs on at county grain.

State zone extents: USDA Plant Hardiness Zone Map (PHZM) 2023. A zone is a 10°F band of average annual extreme minimum temperature, so a state that splits the band contains the boundary — its own page draws the county line, and a parcel report resolves which side your land sits on.

Good to know

One caution for pet owners — alexandria laurel is toxic to dogs and cats (moderate severity). Keep it out of reach, and call ASPCA Animal Poison Control at (888) 426-4435 in an emergency. (Source: Cornell Poisonous Plants Database.)

Alexandria Laurel offers moderate value to bees and other pollinators.

Before you harvest alexandria laurel, know your soil

Anything you grow to eat takes up what's in the ground it grows in, so it's worth knowing what's documented near you before you plant alexandria laurel for food. Our free screen reads 8 federal source types across roughly 1.8M indexed sites and shows which sit near your address and which way they drain. It's a screening estimate from public records and proximity — not a soil test — so a nearby record means a soil test is worth it, not that your soil is unsafe.

How we know this about Alexandria Laurel

The figures above are cited per row, not per site: the pH band names this plant’s own source column, the three temperature figures each carry their own, and days-to-maturity cites the publication that actually lists it. All of it comes from the Growable Ground Plant Database — a compilation over FAO ECOCROP, USDA PLANTS, and university Extension sources, published openly with per-field provenance.

Frequently asked questions

Can I grow Alexandria Laurel in my zone?

Alexandria Laurel grows in USDA hardiness zones 11 through 12 (Hardy to zone 10b: Tropical Plants Database (Useful Tropical Plants) lists -1 °C, converted to zone 10b, checked Oct 2026. The source rates it slightly hardier than our range. Ceiling: our plant database.). Zone is one factor — soil pH, drainage, and frost dates on your specific parcel also shape whether it takes.

When should you plant Alexandria Laurel?

Set alexandria laurel out in early spring or fall while it's dormant, so the roots establish before the heat of summer. Your local last-frost date — which a Growable Ground report pulls for your exact address — sets the precise window.

How much sun does Alexandria Laurel need?

Alexandria Laurel needs full sun — a spot that catches at least 6 hours of direct summer sun a day. In more shade it still grows, but usually gives a smaller, later crop. The catch is that a yard rarely gets even light everywhere — a fence, the house, or one tall tree can quietly take those hours. A Growable Ground report reads the real sun-hours across your land, canopy and buildings included, so you can pick the brightest bed before you plant.

What soil does Alexandria Laurel need?

Alexandria Laurel prefers soil pH 5 to 8, on consistently moist ground (FAO ECOCROP). Your report scores your parcel's actual soil against that using USDA SSURGO data.

Does Alexandria Laurel attract pollinators?

Yes — alexandria laurel's flowers are a solid nectar source for honeybees and native bees.

Is Alexandria Laurel safe for pets?

Alexandria Laurel is toxic to dogs and cats with moderate severity. Keep it out of reach, and call ASPCA Animal Poison Control at (888) 426-4435 in an emergency. (Source: Cornell Poisonous Plants Database.)
