WaterSundrops prefer even moisture and should be watered thoroughly when the top inch of soil feels dry to the touch. In general, water the plant with about 1 inch of water per week but adjust for rainfall accordingly. During dry spells or in particularly hot climates, you may need to water twice a week. Ensure adequate drainage as they do not like to sit in soggy soil. It's better to water in the morning to allow foliage to dry out during the day, reducing the risk of plant diseases.
LightSundrops thrive in full sun conditions where they can receive at least 6 to 8 hours of direct sunlight a day. They are best suited for open areas that are free from shade for most of the day, such as the edge of a garden or in a sunny border. Avoid planting them in shaded areas as it can impede their growth and bloom production.
TemperatureSundrops are hardy and can tolerate a range of temperatures, generally suitable for the plant zone they are grown in. They can survive in temperatures as low as 20°F but strive best in areas where the temperature stays between 60°F and 80°F. Extreme heat above 90°F may slow down flowering, while prolonged cold below the aforementioned minimum can damage the plant.
PruningPrune sundrops to maintain their shape and encourage bushier growth. Deadheading spent blooms will promote more flowers. The best time to prune sundrops is in late winter or early spring before new growth begins. Cut back the old foliage to about 2 to 3 inches above the ground. Pruning every year can also help prevent the center of the plant from dying out.
CleaningAs needed
SoilThe Sundrops, or Oenothera fruticosa 'Fyrverkeri', thrives best in a well-draining soil with a mix of loam, sand, and some organic matter. A slightly acidic to neutral pH of 5.5 to 7.0 suits it well. To improve drainage and fertility, incorporate compost or aged bark into the native soil.
RepottingSundrops plants, which typically have a robust growth habit, may not need frequent repotting. Generally, they should be repotted or divided every 2 to 3 years, or when the plant outgrows its current space, to maintain vigor.
Humidity & MistingThe Sundrops prefers average to low humidity levels, which is typical of most garden environments. It does not require any special humidity adjustments and will thrive in the natural outdoor humidity.

Life cycleOenothera fruticosa 'Fyrverkeri', commonly known as the Sundrops, begins its life cycle when seeds germinate in spring, after which seedlings emerge and establish themselves with a rosette of leaves. As the plant matures, it develops a sturdy stem and a branching habit, sporting narrow, lance-shaped leaves. In early summer, Sundrops produces bright yellow, cup-shaped flowers that open during the day and attract pollinators, leading to the fertilization of flowers and the formation of seed capsules. After pollination, the plant sets seeds that are dispersed by wind, animals, or self-falling near the parent plant. In the fall, the plant begins to die back and enters dormancy during the winter months, conserving energy in the root system. With the return of warmer temperatures in spring, the cycle restarts as new growth emerges from the perennial rootstock.

Spring to early summer
The most popular method of propagating the plant known commonly as the Sundrops or Oenothera fruticosa 'Fyrverkeri' is through root division. This is typically done in the spring or autumn. To propagate by division, gently dig up the plant and carefully separate the root ball into smaller sections, ensuring that each new section has a part of the root system and several shoots. These can then be immediately replanted into a well-prepared soil enriched with organic matter. Plant divisions should be watered thoroughly after planting to reduce transplant shock and encourage root growth. It's an effective way to produce new plants that will be true to the parent plant, as seed propagation may result in genetic variability.
