Night-scented stock, also known as Grecian stock or evening stock, is a hardy annual plant that brings old-fashioned pretty delicacy and gorgeous fragrance to an informal or cottage garden flower border. Its white, lilac, or pink simple four-petalled flowers, borne on slender grey green stems with long narrow leaves, give off a strong sweet perfume in late evening, making them extremely attractive to night-flying moths. They work well in a border as well as in pots, and can be cut for indoor flower displays. Night-scented stock flowers flowers are edible, and can be added to salads.

How to grow night scented stock

It’s best to grow night-scented stock in full sun. It will also flower in dappled shade, but perhaps not as prolifically. The soil should be moist and well-drained, and not highly acidic. Choose a sheltered spot, protected from strong winds that might blow it over, near seating areas where you can appreciate the fragrance, or under a window or by a door so that scent wafts into the house during the evening. Night-scented stock can also be grown in pots.

Night-scented stock doesn’t react well to being moved, so it’s best to sow it directly into the border or pot where you want it to grow. It’s easy to grow from seed and, as it’s hardy, you can sow it in the garden early in the year, even before the frosts have passed (in very mild areas that don’t get frosts, such as coastal areas of southern England, you can sow in autumn). Sowing at intervals from late winter to mid-summer will give you a succession of flowers throughout the season.

Prepare the area by removing any weeds and raking it over, and sow the seed thinly, either scattering it across the patch or drawing wriggly lines in the soil with a stick and sowing the seed along those lines, for a more naturalistic look. Rake again lightly and water in, using a watering can with a rose on its spout, to disperse the water. Depending on the time of year, germination will take between 10 days and three weeks. As the seedlings grow, thin them out in stages to about 20cm apart. The slender stems of night-scented stock are up to 60cm tall and are prone to falling over, so you might consider sowing other hardy annuals alongside it, such as nigella, cornflowers and poppies. These will grow up at a similar rate and provide structural support, while complementing the cottage garden style.
