Coco Plum

About

Coco plum (*Chrysobalanus icaco*) is a coastal workhorse: salt-tolerant, wind-sculpted, and willing to fruit white to dark purple drupes with mild, sometimes insipid, sometimes surprisingly pleasant pulp around a big seed. Forms range from low mounding shrubs to taller upright types depending on ecotype and genetics. In subtropical and tropical Americas it is a gamble without protection; treat serious freezes as a reset button unless you are on thermal mass near the coast. ☀️💧 Sun and Water: - Full sun for best fruiting; tolerates light shade. - Drought-tolerant once established but fruits better with regular deep watering in well-drained soil. Tolerates brackish wind and sandy coasts. ✂️ Propagation: - Seeds: crack or scarify hard endocarp or patience-soak; germination is slow. - Cuttings: hardwood cuttings possible with warmth and humidity. - Transplants: common from nursery containers; stake if exposed to steady coastal wind.

Permaculture Functions

• Edible: Fruits are eaten fresh, jellied, or fermented experimentally — manage expectations on sweetness.
• Erosion Control: Roots stabilize dunes and coastal berms.
• Wildlife Attractor: Fruits feed birds and mammals; flowers support pollinators.
• Windbreaker: Multi-stem habit cuts salt wind in coastal buffers.

Practitioner Notes

• White and red fruit forms differ in sweetness—taste before designing a hedge around the wrong one.
• Salt-front plantings still need establishment water—first two dry seasons determine whether you get a hedge or sticks.
• Suckers from roots—edging or mowing strips keeps formal lines; wild coast plantings look better untamed.
• Mealybugs hide at leaf bases—detail spray with soap hits crawlers; ignoring them paints sooty mold on top leaves.
