Winter flower Power

Have you ever wondered why winter flowers are so highly scented? They are not producing all of those delightful essential oils and fragrances for our benefit, they are sending a powerful message out to any insects that have been woken out of hibernation by a spell of warm weather. Nature is very clever because the sunshine enhances the volatility of the essential oils and helps to release the fragrance which is why the scent is more powerful on a sunny day. The fragrance can be detected by insects from great distances and these winter flowering plants provide vital pollen and nectar for the IMG_0497overwintering insects that will be getting low on energy by now.

The beautiful ‘witch hazel’ Hamamelis ‘Diane’ is highly scented and  fills he air with spicy perfumes from late January, in fact this year it is a couple of weeks behind its flowering time last winter in spite of the milder winter that we are having.

IMG_0502Another shrub with a powerful fragrance is the winter honeysuckle Lonicera x fragrantissima one of the shrubby honeysuckles that bears pairs of fragrant flowers all along its arching stems from January through till April will be covered in bees on a sunny winters day. Spot the pollen sacks on the bee in the photograph!


Also in flower this week Viburnum x bodnantense ‘Dawn’ and Sarcococca confusa both highly fragrant and make excellent cut stems, just a couple of sprigs in water will scent a whole room.

Not all trees and shrubs are insect pollinated. Some are wind pollinated and produce IMG_0498separate male and female floral structures. The male flowers are usually catkins, releasing pollen when they mature. At the moment the hazel trees are in full flower, their make catkins having elongated over the last week or so waving away in the hedgerows distributing their pollen in the wind. Harder to spot are the female flowers that look like miniature sea anemones emerging from small plump buds along the stems. Hazel trees need a period of mildly windy weather without too much rain for the pollen to spread effectively and be caught up on the sticky IMG_0508female floral parts. Unfortunately high winds and heavy rain at this time of the year can lead to a bad crop of  nuts.

With the weather picking up this week in the Limousin why not take the opportunity to go outside and see what nature you can spot in your garden and hedgerows.
