Physical Characteristics Aquilegia flavescens, commonly known as the yellow columbine or golden columbine, possesses a distinctive and attractive physical appearance. Here is a detailed description of its physical characteristics: Size and Growth Habit: Aquilegia flavescens is a herbaceous perennial that typically reaches a height of 60-90 cm (24-36 inches). The plant forms a clump of slender, branching stems that emerge from a basal rosette of compound leaves. Leaves: The leaves of Aquilegia flavescens are light green and have a delicate, fern-like appearance. They are compound, meaning they consist of several leaflets attached to a central stem. The leaflets are lobed, giving them an intricate and feathery appearance. Flowers: The most striking feature of Aquilegia flavescens is its vibrant yellow flowers.

The petals, also yellow, often have contrasting bright red or orange spurs at their tips. The combination of yellow and red-orange hues creates a visually captivating display. Inflorescence: Aquilegia flavescens produces flowers in loose, drooping clusters at the top of the stems. These clusters, known as inflorescences, can contain several individual flowers, each with its own set of sepals and petals. Fragrance: While Aquilegia flavescens is not particularly known for its fragrance, some individuals may detect a mild, pleasant scent when in close proximity to the flowers. It is important to note that variations in physical characteristics can occur within a species, and specific features of Aquilegia flavescens can vary slightly depending on growing conditions, geographic location, and individual genetic traits.
