The story
Açaí palms line the floodplains of the Amazon estuary, where the berries have been pulped into a thick purple mash and eaten with fish and manioc by ribeirinho communities for centuries; the export boom of the 2000s made it a frozen breakfast bowl in Los Angeles.
Planting
Full sun or part shade, wet or constantly moist rich soil, heat and humidity; a clustering palm to 60 feet. Plant seed fresh in the humid tropics.
Growing
Keep wet; it grows in flooded ground. Thin the clump to a few stems for easier harvest. Feed lightly.
Harvest and use
Berries ripen purple in the dry season; climb or cut the clusters, soak and rub the fruit to make the pulp the same day. Hearts of palm from thinned stems.
What to watch for
Drought and cold; nothing else of note.
