5 Seeds Hydrangea paniculata Lime Green Flowers Perennial Garden Shrub

Grow a magnificent hydrangea shrub from seed, renowned for its large, cone-shaped flower clusters in a refreshing lime green hue. This hardy, deciduous perennial adds a soft yet vibrant presence to foundation plantings, borders, or as a standalone accent. Its graceful, long-lasting blooms transition through white and pink tones, providing multi-season interest in your landscape.
Ideal for garden beds, mass plantings, or cut-flower arrangements. The long-lasting panicles can be enjoyed fresh or dried. Seeds are very fine and require patience; surface-sow indoors, keep evenly moist, and provide a cold stratification period of 4–6 weeks to break dormancy. Once established, plants develop sturdy, upright stems and are reliable summer bloomers. Seed-grown hydrangeas may display natural variation in flower color and size.
