sundrops

Sundrops (Oenothera fruticosa 'Fyrverkeri') are relatively drought tolerant and require low amounts of water once established. They prefer soil that drains quickly and can dry out between watering sessions. Water the plant every 7-10 days during the summer months and allow the top 2 inches of soil to dry out between waterings. During the spring and fall, water only when the soil starts to feel dry to the touch, about every 7–14 days. Sundrops require much less water during the winter months, when they go dormant and should only be watered when the soil is completely dry.

Sundrops, also known as Oenothera fruticosa 'Fyrverkeri', require very bright sunlight for maximum growth potential. They prefer 6 to 8 hours of direct, unfiltered sunlight each day during the growing months. To ensure your Sundrops get the most out of each day's sunlight, place them in an area that gets full sun exposure from the early morning until mid-late afternoon. Sundrops can live in partial shade, but they won't bloom as abundantly as those in direct sunlight. Avoid any areas of the garden that get intense, afternoon sun, as this could potentially stress your Sundrops.

Sundrops (Oenothera fruticosa 'Fyrverkeri') should be lightly pruned each year in late winter before they begin growing in spring. Pruning should focus on removing dead or damaged stems and lightly trimming back overly long stems. The shrub naturally forms into a mound, so light pruning may be all that's needed to encourage its shape. Avoid pruning more than 1-third of the total shrub length at any given time.
