Gardening experts have revealed five perennial plants that can keep blooming for decades, with one variety thriving for up to 50 years. These long-lived flowers not only save money but also reduce garden maintenance time, while providing essential food for pollinators like bees, butterflies, and birds.
According to experts at Gardening Know How, baptisia, also known as false indigo, can live in the same spot for 20 to 30 years. It produces lupine-like blooms in spring and eye-catching seed pods in autumn. Its deep taproots make it drought-resistant, though it is slow-growing, so purchasing an established plant is recommended.
Hostas, grown primarily for their foliage, can flourish for 20 to 30 years or more with proper care. Their leaves range from blue-green to variegated white and lime, making them ideal for shaded gardens. Irises, particularly bearded and Siberian varieties, are also long-lived. Bearded irises can last 20 to 25 years if divided every three to five years, while Siberian irises can survive for 30 years or more with little need for division.
Peonies are among the most cherished long-lived perennials, capable of flourishing for more than 50 years. They require minimal upkeep, needing full sun, well-drained soil, and shallow planting. Popular long-lived varieties include Sarah Bernhardt and Karl Rosenfield. Hellebores, stars of the shade garden, have a lifespan of 30 to 40 years and need very little care once established, flowering in late winter and early spring.
