Favorite or New Plant

'Shimmer' evening primrose
Vibrant yellow flowers of this aptly named perennial do seem to shimmer in the sunlight. Oenothera fremontii 'Shimmer' produces three-inch diameter blooms. They provide the most impact when the plant is used as a groundcover or massed in flowerbeds. Plants grow up to 12 inches tall and 15 inches wide. It blooms most heavily in spring, but continues blooming through summer. Pair this evening primrose with purples and grays for an eye-catching color combo. It's rated for USDA zones 4-8, takes full sun, a variety of soil conditions and is low-water-use. It may not perform well in the heat of low desert summers, but the distinct color and attractive, grass-like foliage, makes it worth a try if you like to experiment.
