Delicate summer aroma of mysterious cup-shaped inflorescences!
Native to the southern United States. This is a perennial plant that forms several flowering stems 25-40 cm high in the year of sowing. The leaves are oblong, sparsely toothed along the edge. The flowers are cup-shaped, pink or white, fragrant, up to 5 cm in diameter, collected in a few-flowered apical spike-shaped inflorescence. Flowering from late June to mid-August. The seeds are oval, light brown, 1 g contains about 5000 pcs.
Oenothera is beautiful and unpretentious, but not winter-hardy enough in Estonia.
For planting, allocate a sunny place with well-drained neutral soil. The seeds are sown in March for seedlings on the surface of the substrate, covering with sterile sand by 1-2 mm. Maintain a temperature of +16+20°C and constant humidity. Seedlings are pricked out once in rows at 5 cm intervals or in pots.
In May, hardened seedlings are planted in soil protected from recurrent frosts, at a distance of 45 cm. They can be sown in a breeding bed in spring or early summer, with seeds embedded at 5-10 mm (the substrate must not be allowed to dry out, otherwise seed germination decreases).
After a single picking, seedlings are planted in a permanent place only in autumn or the following spring with a lump of earth. In autumn, the stems are cut off, leaving daughter rosettes, which, with the onset of stable frosts, are covered with a sheet, sawdust or wood shavings in a layer of 15-20 cm. A film is pulled over the top.
The plants can be dug up with a lump and placed in a frost-free basement for the winter, and planted in a permanent place in early spring. For vegetative propagation, use daughter rosettes. Suitable for planting in the foreground of a flowerbed, "lined" along the edge with ageratum or blue lobelia.
Hardy Herbaceous Perennial.
Soft, shell-pink blooms which fade to white in the centre and are veined in a deeper pink. Bright yellow/green throats, free flowering, opening during the day and delicately scented in the evening. An excellent free flowering plant for beds, borders etc which look particularly lovely when grown in drifts.
