珊瑚花屬常綠灌木或半灌木，原產中美洲至南美洲北部。嫩枝草質有細毛，老枝木質化。橢圓形對生葉片。穗狀花序自枝端伸出，卵圓形黃色苞片層疊整齊，花序呈四方塔形。管狀花白色，下脣寬大有淺裂。開花期夏至秋季。

An evergreen shrub or semi-shrub in the genus Pachystachys, native to Central America and northern South America. Shoots herbaceous with fine hairs while aging branches lignified. Oval leaves opposite. Spikes extending from the branch tips, flowers emerging sequentially from overlapping yellow and oval-shaped bracts, the inflorescences 4-sided. Tubular flowers white, the lower lip broad and lobed. Flowering from summer to autumn.

半日照至全日照溫暖環境，夏季曝曬易使葉片黃化。高溫乾燥時花序容易生長不良而短小，冬季低溫生長停滯。花序變色後可及早剪除以促進分枝生長繼續開花。冬季可進行強剪以促進來春萌生新枝開花。繁殖使用扦插法。

The plant grows in a warm environment with partial sun to full sun; direct exposure in summer tends to cause the foliage yellowing. The flowers often grow poorly and are smaller in dry and hot seasons; the growth stagnates at low temperature in winter. Cut off flowers right after they change in color in order to promote branching and flowering consecutively. Perform hard pruning in the winter to promote sprouting in the following spring. Propagated by cuttings.

苞片色彩明亮奪目，適合作為灌叢或綠籬使用。單株即有觀賞性，若與其他粉、紫色系的草花或綠色觀葉植物組合設計，可收色彩襯托輝映的效果。

Featuring with bright-colored and showy bracts, it’s suitably planted as bush or hedge; a single-potted ornamental, or as an accent plant planted with pink or purple grass flowers or green foliage ornamentals to set off the neighbors and create an eye-catching effect.
