Astilbes are perennial flowering plants known for their feathery, plume-like flowers that bloom in various colors, including pink, white, and red. They thrive in shady areas and prefer moist, well-drained soil, making them ideal for woodland gardens and shaded borders. These plants typically grow between 1 to 4 feet tall and can spread up to 3 feet wide. Astilbes are also attractive to pollinators like bees and butterflies, adding beauty and biodiversity to gardens. They are low-maintenance and can be divided every few years to promote healthy growth.
