An often forgotten herb, Galium odoratum, known as Sweet Woodruff can be a valuable addition to the garden, particularly shaded gardens. It makes an excellent ground cover plant due to its low-growing nature and spreading habit.
In spring, tiny white, vanilla-scented flowers hover above fresh green whorls of star-like leaves. Valuable as an under-planting, the plants form a carpet under shrubs and trees and add interesting texture and spark to a deeply shaded part of the garden. The leaves persist right though the year until the new ones burst through the older leaves. A great choice to mix with spring flowering bulbs which can come up through this plant.
Sweet Woodruff is very cold hardy but does not do well in hot areas. It prefers a semi-shady spot that's protected from the sun during the hottest part of the day. It likes moist conditions, and given enough water will grow to a nice low height of about 20cm (8in) tall.
Once established, it likes to take over a patch of ground, it’s not overly aggressive, but will spread nicely within a few years to around 60cm (24in) wide. Be careful to keep it from crowding out other small plants, luckily it is shallow rooted and easy to control. The less light and moisture it gets, the less it will spread.
Sweet Woodruff can tolerate quite a bit of abuse. It will thrive in full or dappled light, and although it likes rich, sandy soil and lots of moisture, it can be planted in the shade around tree roots, which makes it a great plant to help fill in those shady bald spots in the garden.
The soft green leaves are carried in whorls on stems and when the small-petalled white flowers appear above this lush carpet in May and June, the effect is enchanting.
Sowing: Sow seeds as soon as possible.
Sweet Woodruff seeds like many others germinate easily when they are fresh from the plant. As they dry out the germination inhibitors develop and need a period of cold to help break them down.
They are easiest grown when sown directly outdoors in autumn. The seeds require several months of cold winter temperatures to germinate. Keep a check on the compost to make sure it does not dry out. Thin the seedlings in the outdoor bed as necessary.
At other times of year in order to germinate successfully, the seeds may need to be stratified. This replicates the sort of conditions found in nature and is easily achieved by mixing the seed with damp sand or vermiculite and leaving in a polythene bag in the fridge for four weeks. After which time seed can be sown as normal into a seedbed or prepared seed or plug trays. Prick out seedlings into individual pots when they are large enough to handle and plant them out in spring after the frosts are over.
Transplant out into garden into a sunny or part shaded position with well drained, humus rich, moisture retentive soil. After the plants are established, growing sweet woodruff is very simple. It does not need to be fertilised and should only be watered in times of drought.
It is recommended that you plant Sweet Woodruff as a ground cover in an area that you would not mind seeing naturalised. In moist soil. The plants can spread very quickly, you can keep them under control by spade edging around the bed yearly. Remove any sweet woodruff plants that are outside the bed.
