Costus guanaiensis is a tropical plant native to the Amazon region in South America, known for its striking, large, tubular yellow flowers and lush, glossy green foliage. This perennial is part of the Costaceae family and is a popular ornamental plant due to its vibrant blooms and unique appearance.

Growing in a clump-forming habit, Costus guanaiensis can reach a height of 3 to 4 feet (90 to 120 cm). Its large, paddle-shaped leaves are dark green and grow in a spiral arrangement around the stem, giving the plant a dramatic, tropical look. The bright yellow flowers are tubular, often with orange or red highlights at the base, creating a striking contrast against the foliage. These flowers are typically borne in spikes, attracting pollinators such as hummingbirds and bees.

This plant thrives in warm, humid environments and prefers well-drained, fertile soil. It is best grown in partial to full sunlight and requires consistent watering to maintain its lush growth. While Costus guanaiensis is tolerant of some drought, it flourishes when kept in moist conditions. Regular fertilization will encourage vibrant flowering and strong foliage growth.

Due to its exotic appearance, Costus guanaiensis is commonly used in tropical or subtropical gardens, where it can be planted as a specimen plant or in groups to create dramatic color contrasts. It is also ideal for garden beds, borders, and container planting, making it a versatile choice for adding a touch of the tropics to outdoor spaces.

In regions with colder climates, it can be grown as a container plant that can be moved indoors during the winter months. Pruning the plant after flowering will help maintain its shape and promote new growth in the following season.

Costus guanaiensis is a relatively low-maintenance plant, though it does require warm temperatures and high humidity to thrive. It is a great choice for gardeners looking to add a tropical touch to their landscape or for those seeking a vibrant, flowering plant that will attract wildlife.
