Hibiscus
Hibiscus sabdariffa
A ruby-red, tart calyx that cools the body, supports the heart, and makes the most beautiful pitcher of iced tea on a hot day.
At a glance
Sharp, bright cranberry-pomegranate tartness with a subtle floral undertone. The infusion is a luminous garnet — visually stunning, often the reason people fall in love with it.

Modern research
Tradition
Drunk hot in Egypt at weddings, cold across Mexico from sidewalk stalls, hot and spiced in the Caribbean for Christmas, sweet and pink in Senegal as bissap. Few herbs have integrated as deeply or as cheerfully into daily life across so many cultures.
Modern evidence
Multiple randomized controlled trials support modest reductions in blood pressure (similar magnitude to low-dose ACE inhibitors in mild hypertension) and improvements in lipid profiles. Active compounds include anthocyanins, organic acids, and flavonoids that act as ACE inhibitors and natural diuretics.
How to brew
Hot: a tablespoon per covered cup, near-boiling water, eight minutes. Cold infusion: half a cup of calyces per quart of cold water, several hours in the fridge — cleaner, less astringent, and shockingly red. Sweeten to taste; the tartness wants a little balance.
Garden note
Tropical and subtropical only outdoors, but grown in containers in cooler climates. The flowers themselves are short-lived; the plant is grown for the calyces that swell underneath after flowering.
