6. Peony
Peonies are the showstoppers of late spring and early summer gardens. These bold, romantic perennials burst into huge, ruffled blooms in shades of white, pink, red, coral, and even yellow. But it’s not just their size or beauty that makes them beloved—it’s their sweet, luxurious scent. Some varieties, like ‘Sarah Bernhardt’ and ‘Festiva Maxima,’ have a strong fragrance reminiscent of roses and citrus. Peonies thrive in cooler climates and need a period of winter chill to bloom properly, making them ideal for temperate regions. They prefer full sun and rich, well-drained soil, and once established, they’ll come back every year for decades. Though they take a few years to really get going, their stunning look and fragrance make them well worth the wait.
