Golden shrimp plant (Pachystachys lutea)
The Pachystachys lutea, or Golden shrimp plant, offers unique yellow bracts. Ideal for containers in cooler zones.
Complete Plant Information
Overview
The Golden shrimp plant, scientifically known as Pachystachys lutea, is coveted for its striking, long-lasting color far beyond its actual flowers. Its primary appeal lies in the overlapping, brilliant golden-yellow bracts that emerge in dense, 4-sided spikes, lending it the common name “shrimp plant.” Native to the humid tropics of Peru, this broadleaf evergreen thrives in warm, consistent conditions, though it is often grown as a dynamic summer annual or tropical houseplant in temperate regions.
This species provides striking vertical accent planting where it is grown, delivering visual interest through its unique inflorescences which house small, tubular white flowers peeking out from behind the yellow scales. While the true flowers are white, the overriding color provided by the bracts gives the Pachystachys lutea its common nickname, the Lollipop plant. Successfully growing the Golden shrimp plant requires diligent attention to warmth and moisture.
For gardeners in cooler climates, Pachystachys lutea offers an excellent opportunity to bring tropical flair to patios or bright windowsills when treated as a container specimen or overwintered indoors. Its relatively compact size, reaching only 1 to 1.5 feet tall and wide, makes it highly manageable in pots, ensuring its vibrant, shrimp-like structures are always on display during the growing season.

How to Grow
For successful outdoor planting in Zones 10-11, establish Pachystachys lutea in the ground during the spring after all danger of frost has passed. Plants require a moist, organically rich, and well-drained soil base. While it prefers full sun for the most prolific blooming, the Golden shrimp plant will tolerate partial shade, especially in the intense heat of the afternoon sun. If growing as a summer annual outside of these zones, container potting is highly recommended for easy transport indoors before temperatures drop.
Watering needs are medium; ensure the soil remains consistently moist but never waterlogged, as soggy conditions can quickly compromise root health. Fertilizing tropicals like this one generally involves a balanced, water-soluble fertilizer applied every two to four weeks throughout the active growing season (spring through early fall) to support continuous bract production. Pruning is generally minimal, focusing on removing spent stems or shaping the plant to maintain a desired compact habit.
A crucial cultural note for this plant is its temperature sensitivity. Pachystachys lutea dislikes cold, and leaf drop is a common reaction if air temperatures dip into the 60s F. To overwinter the plant, bring containers indoors before the first frost and place them in the warmest, sunniest location available, mimicking its native humid conditions as closely as possible for best results as a houseplant.
Landscape Uses
The unique form and color of the Golden shrimp plant make it an exceptional choice for adding dramatic focal points in the landscape or containers. As a suggested use, it excels as a summer annual, providing bright, exotic interest flanking doorways or lining walkways where its vibrant yellow structures can catch the eye. Because of its manageable height of 1 to 1.5 feet, it performs beautifully when tucked into mixed container arrangements, often serving as a thriller or a bright filler among darker foliage plants.
When grown as a houseplant or greenhouse specimen, the Pachystachys lutea demands a location that receives bright light, often directly in a south-facing window, supplemented by high humidity if possible. In subtropical landscapes, it can function as a low, informal border accent where its color provides season-long impact without requiring deadheading to remove faded flowers.

Noteworthy Characteristics
The Pachystachys lutea, commonly called lollypop plant, golden candle or shrimp plant, is native to Peru, where it grows as a tropical evergreen shrub reaching 2-6 feet tall. When cultivated in containers or temperate zones, the size is significantly reduced, usually topping out around 12 to 18 inches. Its signature look comes from overlapping golden-yellow bracts, which resemble shrimp scales and partially cover narrow, tubular white flowers, providing the primary visual interest. The genus name references these dense flower clusters, while the specific epithet means yellow.
Tolerances
Harvesting Bracts for Color
While the plant is valued for its persistent bracts, gardeners may occasionally want to harvest these structures. When used as a cut flower, the bracts hold their color well, providing a tropical accent in arrangements. However, harvesting too heavily can significantly reduce the overall visual impact of the Pachystachys lutea in the garden or container setting. Always use clean shears when making cuts.
Potential Problems
Pest management is a primary concern, particularly when growing Pachystachys lutea indoors over winter as a houseplant. Watch carefully for common houseplant pests such as aphids, whiteflies, and spider mites, which can quickly infest the leaves and stems. Regular inspection, especially of the undersides of the 6-inch long, medium green leaves, is essential for early detection. Increasing humidity and providing good air circulation can often deter mite populations.
Management strategies should focus initially on cultural adjustments. If pests are found, physical removal via gentle washing or targeted use of insecticidal soap is usually effective. Addressing the previously mentioned environmental stress is also key; since leaf drop often occurs if air temperatures dip into the 60s F, maintaining warmer indoor temperatures will help the plant stay robust and less susceptible to pest colonization.
Frequently Asked Questions
What hardiness zones is Golden shrimp plant suitable for?
Pachystachys lutea is reliably winter hardy only in USDA Zones 10 and 11. In cooler areas, it must be treated as an annual or overwintered indoors as a houseplant.
How large does Pachystachys lutea grow?
When fully mature in its tropical habitat, it can reach 2 to 6 feet, but when grown in containers or as a summer annual in St. Louis, expect it to remain much shorter, typically maturing between 1 and 1.5 feet tall and wide.
What sun exposure does Golden shrimp plant need?
This plant requires full sun exposure for optimal performance and the best development of its signature golden bracts; however, it can tolerate partial shade if necessary.
When does Pachystachys lutea bloom?
It is a seasonal bloomer, primarily producing its distinctive color in the summer months in non-native environments, displaying small white flowers partially obscured by showy yellow bracts.
Conclusion
The Pachystachys lutea, or Golden shrimp plant, remains a favorite for its highly architectural and long-lasting yellow bracts that bring a distinct tropical flair to any setting. Whether utilized as a vibrant seasonal annual or carefully protected as a houseplant, its relatively compact size ensures manageable beauty. Before planting, confirm your local hardiness zone compatibility or plan for a sunny overwintering spot to enjoy the unique coloring of the Golden shrimp plant year after year.
Companion Planting
When planning garden beds or large mixed containers for your Pachystachys lutea, select companions that share its preference for consistent moisture and bright light without demanding excessive heat. Darker foliage plants, such as deep purple sweet potato vine (Ipomoea batatas) or dark-leafed coleus varieties, provide an excellent contrast that makes the brilliant yellow bracts of the shrimp plant visually ‘pop.’ Conversely, pairing the Golden shrimp plant with fine-textured, silver or white annuals can create a softer, more ethereal display.
Since Pachystachys lutea needs organically rich, well-drained soil, pair it with other heavy feeders that appreciate similar soil amendments. Consider annuals like impatiens (for shadier spots) or calibrachoa (for sunny containers) that thrive within similar watering schedules. Keeping companion plants appropriately mulched will also help retain the consistent soil moisture that this tropical native demands.
Propagation Tips
Successfully propagating Pachystachys lutea is straightforward and allows gardeners to easily create new stock for the following season or increase their indoor houseplant collection. The most reliable method involves taking soft to semi-hardwood stem cuttings during the peak growing season when the plant is actively producing new growth. Cuttings should be about 4 to 6 inches long, with the lower leaves removed, and then placed in consistently moist, sterile potting mix or water.
To encourage rapid root development, maintain warmth and high humidity around the base of the cuttings; using a heating mat is highly beneficial. Once roots have adequately formed, usually within several weeks, the new genetically identical Pachystachys lutea plants can be gradually acclimatized to normal room conditions or transplanted into their final growing containers to mature for the next season.
