Vibrant Lemon-Yellow Blooms for Sun-Drenched Landscapes.
Also known as the Missouri Evening Primrose, Ozark Sundrop (Oenothera macrocarpa) is a rugged and rewarding perennial ground cover. It produces exceptionally showy, 7.5 cm wide, poppy-like flowers in a brilliant lemon yellow. While the plants maintain a compact height of 15–30 cm, they are incredibly effective at filling sunny, hot areas where other plants might struggle. This is a tough, drought-tolerant variety that truly thrives in well-drained, less-than-ideal soils, making it a reliable favourite for Canadian rock gardens and borders.

Why Ozark Sundrop Seeds belong in Your Garden
If you have a hot, dry spot in your garden with “difficult” soil, Ozark Sundrop is the perfect solution. It functions more as a serviceable ground cover than a single accent plant, creating a low-maintenance carpet of yellow that shines throughout the summer. Its large, papery blooms open in the late afternoon and evening, providing a unique glow to the garden just as other flowers are winding down for the day.
