Yes. Oenothera speciosa can spread through underground roots and rhizomes, as well as by seed in suitable conditions. It may form expanding patches and become difficult to control in some gardens. Plant it in an area where spreading can be managed, and check local invasive plant recommendations before growing it.
Pink Evening Primrose commonly flowers from late spring into summer, although flowering time varies with climate and growing conditions. Individual flowers are relatively short-lived, but established plants can produce successive blooms over an extended period. Full sun and well-drained soil help support healthy flowering.
