It does not tolerate waterlogged soils and requires moderate watering.
Cultivation
Oenothera drummondii Hook. subsp. drummondii is a summer blooming plant that thrives in full sun. It prefers well-drained soil, but can tolerate a range of soil types. The plant can be grown from seed or purchased as a transplant.
When planting from seed, sow the seeds directly in the ground at the beginning of the growing season. Cover the seeds with a quarter-inch of soil and water gently. Keep the soil moist until the seeds germinate. When planting transplants, space them 18 to 24 inches apart to allow enough room for the plant to grow.
Watering Needs

Fertilization
When growing Oenothera drummondii Hook. subsp. drummondii, fertilize once a month during the growing season with a balanced fertilizer. Avoid over-fertilizing, which can cause excessive foliage growth and reduced flower production. Good fertilizers include those with an N-P-K ratio of 10-10-10 or 5-10-10. Use a water-soluble fertilizer, following the instructions on the packaging, to ensure that the plant is getting the right amount of nutrients.
Pruning
