Hydrangea
Hydrangea is the next most expensive flower in the world on this list, which is native to Asia and the Americas. Hydrangea is mainly white, but it is also sometimes noted for its blue, pink, and light purple flowers. You can see Hydrangea flowers in early spring to late autumn because this is the best time of the year to bloom and they can be sold from $2 to $4.50-$7 per stem.
Hydrangea, commonly named hortensia, by far the most diverse flower species, is grown in eastern Asia, notably China, Korea, and Japan. Most are shrubs 1 to 3 m tall, but some are small trees, and others lianas reach up to 30 m by climbing up trees. Typically the Hydrangea flower heads contain two types of flowers: small non-showy flowers in the center or interior of the flowerhead and large, showy flowers with large colorful sepals. Mostly, today, Hydrangea has been bred and selected to have more of the larger type flowers.
