Each bloom typically has four broad petals, and they open fully during the day (despite the name "evening primrose").

The Beauty of Pink Evening Primrose: A Perfect Addition to Your Landscape
Pink evening primrose (Oenothera speciosa) typically blooms during the day. The flowers open in the late afternoon and remain open until the evening, but unlike some other evening primroses, they are not exclusively nocturnal.
Here are some key points regarding the bloom hours:
- Opening Time: The flowers generally start to open around late afternoon (around 4 PM) or early evening.
- Closing Time: They usually close by late evening, around sunset (approximately 8 PM to 9 PM), depending on the time of year and local light conditions.
- Daytime Flowering: While they are called "evening primrose," these flowers can remain open during the day, especially on cloudy or cooler days.
The blooms attract pollinators, such as bees and butterflies, during their active hours, enhancing the plant's role in supporting local ecosystems.
Why Pink Evening Primrose Is Ideal for Attracting Pollinators and Beneficial Insects
Pink Evening Primrose has been known to grow in fields, thickets, meadows, disturbed grounds, and even roadsides. It naturalizes easily in whatever landscaping environment you want to introduce it to.
This plant produces fruit capsules around mid-August. These narrow seed pods reach about one and a half inches and, when ripe, release over 100 seeds per capsule. This biennial flower has no serious problems with diseases or insects.
While it is an attractive and hardy plant, pink evening primrose can spread aggressively in some regions, so gardeners may need to control its growth to prevent it from crowding out other plants.
