FAQs
What is the difference between a biennial and an annual plant?
A biennial plant, like Evening Primrose, typically completes its life cycle over two years. It grows foliage in the first year and produces flowers and seeds in the second year, after which it usually dies.
When is the best time to sow Evening Primrose seeds?
You can sow seeds directly outdoors from early spring (March to May) or in autumn (September to October).
Will this plant attract moths?
Yes, Evening Primrose is known for its night-blooming flowers, which are particularly attractive to moths, a key pollinator group.
How tall does Evening Primrose grow?
When fully established, Evening Primrose can reach a height of up to 150cm (approximately 5 feet).
Can I grow Evening Primrose in pots?
While it thrives in open ground, it can be grown in large containers with good drainage, provided it receives full sun and is watered regularly.
What is the Kew Pollinators range?
The Kew Pollinators range is a collection of seeds developed in collaboration with the Royal Botanic Gardens, Kew, focusing on plants that attract and support vital pollinating insects.
What should I do if I have too many self-seeded plants?
You can thin out excess seedlings in spring or autumn. Alternatively, you can transplant unwanted seedlings to new locations or give them to friends.
Troubleshooting
Seeds not germinating
Ensure seeds have good soil contact, are not sown too deeply, and the soil is kept consistently moist. Check that the sowing period is appropriate for your climate.
Plants are leggy or weak
Ensure the plant is receiving adequate sunlight. Insufficient light can lead to weak, stretched growth.
Few flowers produced
Confirm the plant is in its second year of growth, as it is a biennial. Ensure it has sufficient sunlight and is not overcrowded.
Plant is too tall and floppy
Consider planting in a location with some shelter from strong winds. For very tall specimens, staking might be necessary.

Setup, Compatibility & Care
Sowing: Sow seeds directly outdoors from early spring (March-May) or autumn (September-October) into well-prepared soil. Lightly rake seeds into the soil surface, ensuring good soil contact. For best results, sow in a sunny position with light, sandy, well-drained soil.
Watering: Water seeds regularly until established. Once mature, the plant is relatively drought-tolerant, though benefits from occasional watering during prolonged dry spells.
Weeding: Keep the area around young seedlings free from weeds. Established plants are generally competitive.
Deadheading: While not essential for plant health, removing spent blooms can prevent excessive self-seeding if desired.
Soil Type: Prefers light, sandy soils. Avoid heavy clay or waterlogged conditions.
Sunlight: Requires a full sun position for optimal flowering.
