In the garden
Romneya × hybrida of gardens is a perennial shrub native to California, USA, cultivated in temperate gardens for its notable summer flowering and mild, sweet scent. Flowering occurs from June to August. Give the plant a sunny, south-facing position; it requires full sun and free-draining sandy or loamy soil with a neutral to slightly alkaline pH. Soil moisture should be on the dry to medium side, so avoid heavy, clay soils that retain water. Its UK hardiness rating is H5 (hardy), which means it will survive typical winter conditions across most of the country outside the coldest exposed sites. Exposure can range from sheltered to exposed, so it tolerates wind where drainage is good. Use it at the rear of sunlit borders, as a feature beside a sun-facing wall, or within xeriscape planting schemes where low to moderate moisture and bright light are available. Allow plenty of space and a reliably sunny aspect so its summer flowers and mild fragrance can be enjoyed from a nearby path or patio.
