This plant is a perennial herb belonging to the Acanthaceae family. Its height ranges from 60 cm to 1 meter, with an upright and branched stem, forming dense clumps. Its leaves are a deep, dark green, oval-shaped with a slightly rough texture.
The main highlight is the yellow bracts in the shape of a spike, from which delicate white tubular flowers emerge. Flowering occurs mainly in the spring and summer, but can happen year-round in warm climates. This plant also attracts pollinators such as bees and hummingbirds, making it an excellent ecological option for the garden.

The yellow shrimp plant adapts well to both garden and pot cultivation. In the garden, it can be planted in beds with good sun exposure, preferably in locations that receive direct light for at least four hours daily.
Partial shade is also tolerated, as long as the light is sufficient to stimulate flowering. Avoid very shaded areas, as the plant tends to produce fewer flowers and grow in a more elongated and less vigorous manner in those environments.
To ensure healthy growth, the soil must be fertile, light, and well-drained. Ideally, prepare a mixture of potting soil with coarse sand and organic matter, such as worm castings or organic compost.
This type of soil prevents waterlogging, which can rot the roots, and provides the necessary nutrients for the plant to grow vigorously and bloom regularly. In beds, thoroughly turn the soil before planting and add organic matter to improve the soil structure.
If opting for pot cultivation, choose containers with at least 30 cm of depth, allowing for root development. It's important to ensure drainage holes at the bottom and, preferably, use a layer of gravel or expanded clay before adding the substrate.
This practice helps to avoid water accumulation and reduces the risk of fungi. Ceramic or clay pots are good options as they allow soil transpiration and maintain a more stable temperature for the roots.
The yellow shrimp plant enjoys slightly moist soils, but not waterlogged. Watering should be done whenever the soil is dry on the surface, which may mean watering two to three times a week in warmer climates. During rainy periods or cooler temperatures, the frequency can be reduced.
The ideal is to observe the plant and adjust watering according to need, always avoiding excess water, which can cause root rot and favor fungal diseases.
Although it tolerates partial shade, Pachystachys lutea blooms better when grown in full sun. Areas with good light, such as balconies, terraces, or well-lit windows, are ideal for those cultivating in pots.
Sunlight is essential for the formation of the yellow bracts and white flowers, in addition to keeping the plant more compact and attractive. In indoor

Pruning is important to keep the yellow shrimp plant with a beautiful shape and to stimulate new bloomings. Prune after the flowering cycle, removing dry or excessively long branches.
During spring and summer, fertilize every 30 days with phosphorus-rich fertilizers (like NPK 4-14-8), which encourage flowering. In autumn and winter, reduce the frequency.
Water whenever the soil is dry on the surface. The plant likes humidity but does not tolerate waterlogging. Excess water can cause root rot.
Despite being resilient, the plant may be attacked by aphids, mealybugs, or mites. To prevent them, maintain ventilation and, if necessary, apply neem oil or insecticidal soap.
Avoid cultivating in areas with too much wind, as the more delicate branches can break. In outdoor
Remove dry flowers and bracts frequently to keep the plant looking beautiful and stimulate the production of new shoots.
If in a pot and exposed to light from one side only, rotate the container weekly to ensure uniform growth.

The yellow shrimp plant stands out in tropical compositions and can be combined with various other species to create interesting visual effects. Its vibrant tone contrasts well with deep green foliage, such as that of monstera or calathea.
It can also be harmonized with warm-colored flowers, such as heliconias and sugarcanes, or with white flowering species, creating a more balanced look. Smaller or trailing plants, such as purple lambari, complement its height well. In decorative pots, it can be accompanied by ferns or syngoniums to create tropical arrangements full of life and texture.
The CASACOR promotes the use of native plants, and thus warns that, as it is an exotic plant, its use may compromise the development of native species and cause imbalances in certain ecosystems. We therefore recommend caution in its cultivation.
