Pachystachys lutea, known as the golden wax plant or lollipop plant, is a low-stemmed tropical evergreen shrub growing between 0.5 and 2.5 meters tall, native to Peru. Its zygomorphic, long-throated, short-lived white flowers emerge in succession from overlapping, bright yellow leaves on racemes produced during the warmer months.

It is cultivated as an ornamental plant, but in cooler climates it requires protection from temperatures below 10 °C (50 °F). It has won the Royal Horticultural Society's Award of Garden Merit.
