Guzmania lingulata
Scarlet-star
Guzmania lingulata
Guzmania lingulata, commonly known as the Scarlet Star, is a striking epiphytic bromeliad native to tropical rainforests of Central and South America. It typically grows on trees, absorbing moisture and nutrients from the air and rain. Its most notable feature is a vibrant, star-shaped inflorescence, composed of brilliant red, orange, or yellow bracts (modified leaves) that surround a cluster of small, inconspicuous white flowers. Unlike many plants, Guzmania lingulata forms a 'tank' or 'cup' at its center with its overlapping leaves, which collects water and serves as its primary water source. The plant typically blooms once in its lifetime, and after flowering, the mother plant gradually dies, producing offsets or 'pups' around its base to continue the cycle. It is highly valued as an indoor ornamental plant for its exotic appearance and relatively easy care.

Pollination

Method: animal

Notes: In their natural habitat, Guzmania lingulata is primarily pollinated by hummingbirds and various insects attracted to its brightly colored bracts. For indoor cultivation, manual pollination can be attempted by transferring pollen from one flower to another using a small brush or cotton swab to encourage seed production, though this is rare for home growers who typically propagate via pups.

Watering Requirements

Method: top water

Frequency: Keep central cup filled with fresh water; flush weekly. Water potting mix when top inch is dry.

Notes: It is crucial to keep the central 'cup' or 'tank' of the plant filled with clean, fresh water. Use distilled water or rainwater to prevent mineral buildup. Flush the cup weekly by tipping out old water and refilling. Water the potting mix sparingly, allowing it to almost dry out between waterings, as the plant primarily absorbs water through its cup.

Humidity Requirements

Level: high

Maintenance: Misting daily or every other day, using a humidity tray, or placing the plant near a humidifier are effective methods to maintain the high humidity levels (60-80%) that Guzmania lingulata thrives in.

Care InstructionsMaintain a consistently filled central cup with clean, non-chlorinated water, flushing it regularly to prevent stagnation and bacterial growth. After the plant flowers, the mother rosette will gradually decline and die, but it will produce several 'pups' (offsets) at its base. These pups can be separated and repotted once they reach an adequate size to continue the plant's life cycle. Do not fertilize the central cup; instead, use a very diluted liquid fertilizer applied to the potting medium or as a foliar spray on the leaves.
Alternative NamesCaraguata lingulata
Nephrolepis exaltata
southern sword fern
Nephrolepis exaltata
Boston ferns prefer high humidity and indirect light, much like Guzmania. While ferns are terrestrial, their dense foliage can help increase local humidity around the Guzmania, and they won't aggressively compete for resources if the Guzmania is potted in its preferred bark-based mix.
Ficus benjamina
Weeping fig
Ficus benjamina

Weeping figs can grow very large and cast dense shade, which is not ideal for Guzmania's bright, indirect light requirements. If planted in close proximity, the fig's extensive root system could also outcompete for any shared moisture or nutrients in a communal pot, though Guzmania's needs are minimal.

Spathiphyllum wallisii
Peace Lily
Spathiphyllum wallisii

While peace lilies enjoy humidity, they are heavy drinkers and require consistently moist soil, which is significantly different from Guzmania's need for a well-draining, slightly moist medium and filling of its central cup. Pairing them could lead to overwatering for the Guzmania or underwatering for the peace lily.

Zamioculcas zamiifolia
Zanzibar gem
Zamioculcas zamiifolia

The ZZ plant is highly drought-tolerant and thrives on infrequent watering, often preferring its soil to dry out completely between waterings. This contrasts sharply with Guzmania's need for consistent moisture in its central cup and a moderately moist potting mix, making them incompatible due to conflicting watering regimes.

Mealybugs

Mealybugs appear as small, white, cottony masses, typically in leaf axils or on the undersides of leaves. They suck sap from the plant, leading to stunted growth, yellowing leaves, and a general decline in vigor. A sticky residue called honeydew may also be present.

Scale Insects

Scale insects are small, oval, motionless bumps (brown, black, or reddish) found on stems and leaves. They feed on plant sap, causing yellow spots, wilting, and leaf drop. Like mealybugs, they excrete honeydew, which can lead to sooty mold growth.

Spider Mites

Spider mites are tiny arachnids that cause fine stippling (tiny dots) on leaves and can create delicate webbing, especially in severe infestations. They feed on plant cells, leading to yellowing, bronze discoloration, and eventual defoliation. They thrive in dry conditions.

Steps:

    • Wait until the pup (offset) reaches approximately one-third to one-half the size of the mother plant. This usually ensures the pup has developed its own root system.
    • Carefully separate the pup from the mother plant using a sharp, clean knife or pruning shears. Make the cut as close to the mother plant as possible, ensuring some roots are attached to the pup if visible.
    • Plant the separated pup in a small pot (about 4-6 inches in diameter) filled with a well-draining, airy potting mix specifically designed for bromeliads or orchids (e.g., a mix of orchid bark, perlite, and sphagnum moss).
    • Ensure the base of the pup is just below the surface of the potting mix, providing stability.
    • Water the potting mix lightly to keep it slightly moist, and fill the central 'cup' of the pup with fresh, clean water.
    • Place the newly potted pup in a location with bright, indirect light and maintain high humidity.
    • New roots should form within a few weeks, and the pup will begin to grow into a mature plant.

Bromeliad potting mix

Provides the ideal well-draining, airy environment necessary for Guzmania roots, mimicking their natural epiphytic substrate.

Balanced liquid fertilizer (e.g., 20-20-20 at 1/4 strength)

Provides essential nutrients. Apply to the central cup or as a foliar spray during the growing season; bromeliads absorb nutrients through their leaves.

Neem oil spray

A natural insecticide and fungicide effective against common pests like mealybugs, scale, and spider mites. It disrupts their feeding and reproduction.

Insecticidal soap

An effective and safe option for smothering soft-bodied pests like mealybugs and spider mites on contact without harming the plant or environment.

Humidity tray

Increases local humidity around the plant, crucial for Guzmania's tropical needs, by evaporating water from a tray filled with pebbles.
