The hydrangea event is an occasion where you can see and learn about various hydrangea varieties in person. Set in the lush natural space of Oizumi Ryokuchi, you can enjoy hydrangeas of different colors and shapes up close. The event also features panels introducing the characteristics and names of each variety, enhancing your flower-viewing experience. Different areas are planted with hydrangeas of diverse colors and blooming styles, allowing you to observe color transitions as you stroll. There are several picturesque spots perfect for photos, making it a charming activity to take a slow walk with your camera. Professional staff provide flower explanations, letting you learn about the history, cultivation, and interesting facts of hydrangeas. For a limited time, there will be a special display area for unique and rare hydrangea varieties, an exclusive feature of this event that flower lovers shouldn't miss. There will also be a hydrangea seedling giveaway, offered to early visitors. The most recommended way to enjoy the event is to join the hydrangea stamp rally with a pamphlet in hand, touring all the areas to discover the deep charm of hydrangeas and receive a commemorative gift.
