Justicia tinctoriella, commonly known as Yellow Justicia, is a perennial herb that is native to Central America, often found in open woodlands and forest edges where it benefits from dappled sunlight. This species typically exhibits a bushy growth habit and can reach heights of up to 3 feet (1 meter). Yellow Justicia is notable for its vibrant yellow tubular flowers that bloom in clusters, primarily during the warm months, providing a long-lasting display of color. The flowers are particularly showy and attract pollinators such as bees and butterflies.

In cultivation, Yellow Justicia is appreciated for its ease of maintenance and the bright splash of color it adds to garden borders, mixed beds, and as an accent plant. It thrives in well-drained soils enriched with organic matter and prefers consistent moisture, though it can tolerate short periods of drought once established. Yellow Justicia performs best in full sun to part shade conditions. While generally pest-free, it can occasionally suffer from aphids or spider mites. It is not known for aggressive roots or significant disease issues. This herb is not typically associated with invasiveness when grown outside its native range, making it a safe choice for most gardens.CC BY-SA 4.0
