Poukhanense, also called Korean Yodogawa Azalea, is one of if not the most cold tolerant Azaleas we offer, cold hardy as far north to USDA Zone 4a. It is equally as heat tolerant to USDA Zone 9. If you love the color lavender you're going to love Poukhanense. LOADS of 2-inch wide lightly fragrant lavender flowers, each with a darker blotch of freckles, smother the plant in spring.
