Hydrangea is a popular ornamental flowering plant admired for its large, showy blooms and lush foliage. It belongs to the genus Hydrangea in the family Hydrangeaceae and is commonly grown in gardens and landscapes around the world.

Hydrangea plants are typically deciduous shrubs, though some species grow as climbers or small trees. They have broad, oval to heart-shaped green leaves with a soft texture and prominent veins. The flowers grow in large, rounded or cone-shaped clusters called inflorescences, which can be mophead, lacecap, or panicle in form.

One of the most distinctive features of hydrangeas is their color-changing ability. Depending on the species and soil pH, flowers may appear blue, pink, purple, white, or green. Acidic soils tend to produce blue flowers, while alkaline soils result in pink blooms. White varieties usually keep their color regardless of soil conditions.

Hydrangeas bloom from late spring through summer, and some varieties continue into early fall. They prefer moist, well-drained soil, partial shade, and regular watering. Because of their long-lasting flowers and attractive appearance, hydrangeas are widely used in gardens, borders, hedges, and floral arrangements.

Overall, hydrangeas symbolize gratitude, grace, and abundance, making them both visually striking and meaningful plants in ornamental horticulture.
