Wallisia cyanea, commonly known as Pink Quill, is a popular houseplant. Its unique and vibrant appearance makes it a distinctive addition to indoor plant collections.
Meet the Pink Quill
Wallisia cyanea is a bromeliad species native to the rainforests of Ecuador. It is naturally epiphytic, growing on other plants or structures, using its roots primarily for anchorage. The plant forms a rosette of thin, recurved, green, strap-like leaves, which can reach up to 20 inches in height and width.
The Pink Quill’s most distinguishing feature is its prominent, paddle-shaped inflorescence. This vibrant pink structure resembles an old-fashioned ink quill and can last for several months. Small, delicate violet or blue flowers emerge sequentially from the pink bracts, each lasting only a few days.
Essential Care for Wallisia Cyanea
Light
Pink Quill plants thrive in bright, indirect light. An east or west-facing window with filtered sunlight is ideal, providing sufficient brightness without harsh direct exposure. Direct sunlight, especially during the hottest parts of the day, can scorch leaves and the pink bract, causing discoloration. If natural light is limited, a lightly shaded area is suitable.
Watering
Watering Wallisia cyanea involves both its roots and its central “cup.” If potted, keep the growing medium slightly moist but not waterlogged, allowing the top inch of soil to dry between waterings. Light misting of the central cup every few days is beneficial. Avoid letting water sit in the cup for more than a day or two to prevent rot. Use distilled water or rainwater, as Pink Quills are sensitive to chemicals like chlorine and fluoride found in tap water.
Humidity
These plants flourish in high humidity, ideally around 50-70%. To increase humidity, place the plant on a pebble tray filled with water, ensuring the pot does not sit directly in the water. Using a room humidifier is also effective. Regular misting of the leaves a few times a week helps maintain moisture levels.
Temperature
Pink Quill plants prefer moderate temperatures, thriving between 60-85°F (16-29°C). Consistent indoor temperatures are beneficial. Keep the plant away from sudden temperature fluctuations, like cold drafts or heating vents. Avoid temperatures below 50°F (10°C).
Soil/Substrate
While many air plants do not require soil, Wallisia cyanea can be grown in pots with a well-draining substrate. Suitable potting mixes include orchid bark, a bromeliad-specific mix, or a blend of perlite and a small amount of peat moss. Ensure the medium allows for adequate drainage and airflow. The Pink Quill can also be mounted on solid substrates like timber or cork bark.
Fertilization
Pink Quill plants have modest fertilization needs. During the growing season, apply a balanced, water-soluble fertilizer diluted to half strength once a month. Bromeliad or orchid fertilizers are suitable. Apply the diluted solution by misting onto the leaves and bract, or by watering the soil.
Repotting
Repotting is infrequent for Wallisia cyanea, as its root system is small and primarily for anchorage. Repotting may be necessary every 2-3 years, or when the plant outgrows its container. This is best done in spring, using a shallow, wide pot with a fresh, well-draining mix.
Pruning
Minimal pruning is required for the Pink Quill. Prune to remove any dead or yellowing leaves. After the pink bract fades and the flowering cycle completes, cut away the spent flower spike at its base.
Toxicity
Wallisia cyanea is non-toxic to both pets and humans.
Life Cycle and Propagation
Wallisia cyanea is a monocarpic plant, meaning the main plant declines and dies after flowering. This is a natural process, not an indication of improper care. Before the mother plant dies, it produces small offsets, called “pups,” around its base.
Once pups are at least one-third the size of the parent plant, they can be separated. Plant these offsets in their own containers with a suitable well-draining medium. It can take several years for these propagated pups to mature and produce their own blooms.
Solving Common Pink Quill Problems
If Pink Quill leaves develop brown tips or appear scorched, it indicates too much direct sunlight or insufficient humidity. Move the plant to bright, indirect light and increase ambient humidity.
When the plant’s base becomes mushy or root rot occurs, overwatering or poor drainage is the cause. Ensure the potting medium is well-draining and dries slightly between waterings. Also, avoid water sitting in the central cup for prolonged periods.
A lack of flowering or absence of the distinctive pink bracts is often due to insufficient light. Move the plant to a brighter, indirect light location to encourage blooming. Pink Quill plants can be affected by pests like mealybugs or scale insects, which can be managed with houseplant pest treatments.
