Morphology and Growth Habits The physical appearance of Agalinis acuta, commonly known as the graceful gentian, is characterized by its slender stems, narrow leaves, and vibrant flowers. Here is a detailed description of its physical features: Stems: Agalinis acuta has multiple erect stems that arise from a branching base. These stems are slender and square-shaped, and they can reach a height of 20-60 cm (8-24 inches). The stems are covered with fine hairs, giving them a slightly fuzzy texture. Leaves: The leaves of Agalinis acuta are linear in shape, meaning they are long and narrow with parallel sides. The leaves are oppositely arranged along the stems, meaning that they grow in pairs on opposite sides of the stem. They measure about 2-7 cm (0.8-2.8 inches) in length. The leaf margins are smooth, and the tips are sharply pointed, giving them an acute appearance. Flowers: The flowers of Agalinis acuta are the most captivating aspect of this plant. They are typically pale pink to lavender in color, although variations in shade can occur. The flowers have five petals that are fused together to form a tubular corolla. The corolla measures around 1-2 cm (0.4-0.8 inches) in length. The upper petal of the corolla forms a hood-like structure, while the lower petal acts as a landing platform for visiting pollinators. The flowers are borne in clusters at the top of the stems, creating an attractive inflorescence. Overall, Agalinis acuta has a delicate and graceful appearance, with its slender stems, narrow leaves, and charming flowers. Its physical features contribute to its beauty and make it a sought-after wildflower among plant enthusiasts and nature lovers.
