Types of Primrose
Primroses often get attention for their delicate blooms and adaptability in different growing conditions. But not all primroses are the same—and not all of them are welcome in your yard. While some are garden favorites, others can become invasive weeds that spread quickly and take over your lawn. Let’s take a closer look at a few common types of primrose, including the showy evening primrose, which is considered more of a nuisance than a flower.
Common Primrose (Primula vulgaris)
This is the primrose most people think of when they picture cheerful yellow blooms in early spring. Common primroses are usually planted in gardens, window boxes, and borders because they provide bright color after winter. They thrive in cooler weather and are often cultivated as ornamental plants.
Evening Primrose (Oenothera biennis)
Evening primrose is known for its tall stems and pale yellow flowers that bloom in the evening and close by midday. Unlike showy evening primrose, this type has been used in herbal remedies and is less invasive in most landscapes. It tends to grow in open areas and along roadsides but is not typically a major lawn problem.
Showy Evening Primrose (Oenothera speciosa) – The Weed You Don’t Want
Unlike its relatives, the showy evening primrose is considered an invasive weed in Texas and many other areas. Its light pink blooms may look charming at first, but this plant spreads aggressively by both seeds and underground rhizomes. Once it finds a spot in your lawn, it’s very difficult to control and can quickly crowd out healthy grass.

The Bottom Line
Primroses can range from garden-friendly flowers to invasive weeds, depending on the species. While common and evening primroses may brighten a flower bed, the showy evening primrose is one to watch out for in your lawn. Staying proactive with weed control and proper lawn maintenance is the best way to keep it from spreading.
