Understanding Plant Options
Nature Hills offers plants in two main formats:
- Container Plants: Grown in pots with soil, sized by container volume and plant age
- Bare Root Plants: Dormant plants without soil, sized by height measurements
Container Plant Sizes
Container sizes indicate plant age and growing capacity rather than liquid volume equivalents. Our containers follow industry-standard nursery "trade gallon" specifications, which differ from standard liquid gallon measurements.

Planting & Care
Planting & Care
Gorgeous living drops of sunshine, the Bigfruit Evening Primrose (Oenothera macrocarpa) features four big fluttering petals in the most delicious lemon yellow that wave atop a low-growing mat of airy fine-textured gray-green foliage! Lasting a single evening each, the scented blooms keep returning for a long-lasting display each spring.
Native Big-Fruit Primrose can be sometimes upright, but usually trailing or carpet-forming. These are popular pollinator plants, especially for Hawk/Hummingbird/Sphinx Moths and other evening butterflies, moths, and beneficial insects! The flowers can keep reblooming throughout the growing season until August in some areas!
Evening-Primrose are hardy little native perennial wildflowers that go by many names, including Ozark Sundrops, Fluttermill, and Missouri Evening Primrose. Hardy throughout USDA growing zones 3 through 7 and forming polite colonies of sunny yellow carpets 6-12 in height and 12-18 inches wide.
Planting and Application:
These wildflowers are often seen growing throughout sunny meadows and prairie edges, partially shaded glades & bluffs, roadsides, and creeping along hillsides. So they do remarkably well as low-growing groundcovers and garden fillers! Plant as meandering edging and facer plants to add a touch of sunshine to garden transition areas, or just let Primrose run freely throughout a sunny swath of landscape.
Use in Rock Gardens, Pollinator Borders, Moon Gardens, or as spillers in containers. Bigfruit Primrose looks great rambling over the tops of retaining walls, along the fronts of sunny, Xeric gardens, and in areas with poor soil. Happily rambling along the dappled shade areas along mixed shrub gardens, around larger perennials, and beneath a tree-lined understory.
- Bright Four-Petalled Yellow Blooms
- Many Blooms Spring Til Fall - Each Lasts One Evening
- Self-Sowing, Spreading Native Perennials
- Pollinator-Friendly Xeric Plants
- Borders & Edging, Low Garden Filler & Long-Lasting Native Color
#ProPlantTips for Care:
Evening Primrose requires full sun and handles some partial shade, especially those in hotter climates and in drought-prone conditions. Oenothera needs a good drainage site, handling sandy and rocky soil with ease. Water these herbaceous perennials regularly during their first year in the ground, but once established, Primrose can be very drought-tolerant. Prune back the plants in the late fall or winter. Evening Primrose are fairly deer resistant and are seldom damaged unless desperate.
- Full Sun & Partial Shade
- Well-Drained Soil - Highly Adaptable
- Moderate to Low Moisture Needs
- Prune Late Autumn/Winter
- Deer Resistant Native
Bright and colorful summer-long beauty, the Bigfruit Evening Primrose is just the hardy native your landscape needs! Easy care and fuss-free, order low-maintenance perennials from Nature Hills today!
