Pachystachys lutea, known as the golden shrimp plant or lollipop plant, is a tropical, soft-stemmed evergreen shrub between 0.5 and 2.5 meters tall, native to Peru.[1][2] The zygomorphic, long-throated, short-lived white flowers emerge sequentially from overlapping bright yellow bracts on racemes that are produced throughout the warm months.[1]

The Latin specific epithet lutea means “yellow”.[3]

It is cultivated as an ornamental, but in cold temperate regions it requires protection from temperatures below 10 °C (50 °F).[4] It has won the Royal Horticultural Society’s Award of Garden Merit.[4][5]
