Pink evening primrose Oenothera speciosa 'Siskiyou'
ABOUT
The Oenothera speciosa 'Siskiyou', commonly known as the Pink Evening Primrose or Showy Evening Primrose, is a flowering perennial that boasts a lush spread of foliage and vibrant blooms. Its leaves are narrow and lance-shaped, with a soft green hue that creates a delicate backdrop for the flowers. The blooms themselves are the main attraction, notable for their delicate pale pink to white petals that often display a gradient of color, with darker shades at the base that fade to lighter tones at the edges. Each flower features a prominent cross-shape, typical of the genus, with four broad petals that open outwards. The Pink Evening Primrose’s flowers have a satiny texture and a soft, inviting appearance. These blossoms are typically cup-shaped and open in the evening, hence the name 'Evening Primrose'. They release a gentle and pleasing fragrance that becomes more pronounced as daylight fades. Although I am restricted from mentioning the specific size of the plant, the Pink Evening Primrose forms a substantial spread that bursts into a profusion of blooms, creating an attractive ground cover or border plant that can add a touch of wildflower meadow to a garden setting. The flowering period extends through spring and summer, offering an enduring display of color and beauty.

WaterPink evening primrose needs regular watering, especially during the first growing season to establish a deep, extensive root system. Once established, reduce frequency, except during extreme drought. Provide a deep watering every other week, ensuring soil is moist but not soggy. Generally, aim for about one inch of water every week during active growth periods, which equates to roughly 0.6 gallons per square foot per month.
LightPink evening primrose thrives in full sun exposure, which means it prefers a spot that receives at least 6 to 8 hours of direct sunlight daily. It can tolerate partial shade, but flowering will be reduced. It is best to plant it in a location where it can enjoy unfiltered sunlight throughout most of the day.
TemperaturePink evening primrose is tolerant of a wide range of temperatures, but it performs best in moderate to warm conditions between 60°F and 90°F. It can survive minimum temperatures down to about 20°F, but freezing temperatures can damage the plant. Its optimal growing conditions include warm days and cooler nights.
PruningPink evening primrose benefits from occasional pruning to stimulate new growth and encourage more blooms. Prune back spent flowers and dead stems after the blooming period to maintain plant health and appearance. Pruning can be done once a year, usually in the late fall or early spring before new growth starts.
CleaningAs needed
SoilThe Pink Evening Primrose prefers a well-draining soil mixture with loamy or sandy characteristics; a mix of two parts garden soil, one part sand, and one part compost is ideal. The soil pH should be neutral to slightly acidic, around 5.5 to 7.
RepottingPink Evening Primrose does not typically need frequent repotting as it is a perennial plant. Repotting every two to three years or when root-bound is sufficient to maintain its health.
Humidity & MistingPink Evening Primrose is tolerant of various humidity levels and does well in the average outdoor humidity; it does not require any specific humidity adjustments.
Suitable locationsIndoor
Place in bright, indirect light and keep the soil lightly moist.

Life cyclePink evening primrose (Oenothera speciosa 'Siskiyou') is a perennial plant that starts its life cycle as a seed, which, under appropriate conditions of warmth and moisture, germinates in the soil. The seedling emerges and develops true leaves, growing into a juvenile plant. Over time, it matures into an adult plant with a robust root system and foliage. During the flowering stage, typically in spring or early summer, it produces showy pink flowers that open in the evening and close by midday. After pollination, usually by moths or bees, the flowers develop into fruit capsules containing numerous seeds. Once these seeds are mature, they are dispersed by wind or animals, completing the cycle when they germinate and grow into new plants.
PropogationPropogation time
Spring to Summer
Propogation: The Pinkladies or Pink Evening Primrose, Oenothera speciosa 'Siskiyou', is commonly propagated by seed. The ideal time for sowing seeds is in the fall, as Pinkladies require a period of cold stratification to germinate successfully. After the seeds have undergone cold stratification, they may be sowed directly into a well-draining soil medium where they will germinate when the temperatures rise in spring. To ensure best results, sow the seeds on the surface of the soil and lightly press them in, as they need light to germinate. Keep the soil moist but not waterlogged. Once the seedlings have developed several true leaves, they can be transplanted into individual pots or directly into the garden where they will continue to grow and eventually flower.
