Dandelion Botanical illustration - Taraxacum officionale

W&N watercolour on Bockingford 300gsm 

Taraxacum officinale, the common dandelion (often simply called “dandelion”), is a flowering herbaceous perennial plant of the family Asteraceae.

It can be found growing in temperate regions of the world, in lawns, on roadsides, on disturbed banks and shores of water ways, and other areas with moist soils. T. officinale is considered a weed, especially in lawns and along roadsides, but it is sometimes used as a medical herb and in food preparation. Common dandelion is well known for its yellow flower heads that turn into round balls of silver tufted fruits that disperse in the wind called “blowballs” or “clocks” (in both British and American English).

During summer, when the Dandelions are in full flower, I mostly halt mowing the lawn, enjoying the spectacle of yellow flowers and then the beautiful blow-balls. And, like a child, I often pick them and blow them into the wind, revelling in the little umbrellas as they take off to start a new generation of Dandelions.

Dandelions are a Eurasian species now entrenched almost world-wide because of their excellent seed dispersal mechanism and ease of germination. Their crowded head of ray flowers produces numerous seeds, their low, wide basal leaves crowd-out competing plants, and thus the plant is often found in huge colonies.

Bluegum leaves (Eucalyptus)
Dedicated to all Eucalypt and Bee-lovers!

A recent study by the SA National Biodiversity Institute (Sanbi) in South Africa has found that gum trees provide nectar and pollen for swarms of commercial bees – and bees in turn pollinate about 50 food crops in the country. This “service” bees provide is worth about R10.3 billion a year.

Gum trees are not only important food for bees, but so are many roadside wildflowers, crops, suburban flowering plants and those that many regard as weeds. A major reason for the decline of honey bees around the world is a lack of good forage plants to provide nectar, which is the carbohydrate in the bees’ diet, and pollen the protein. Bees collect nectar from Blue Gum tree blossoms from spring to late summer.

A lack of good quality and variety of forage plants can lead to unhealthy honey bee colonies that are more vulnerable to pests and diseases.

This in turn can lead to insufficient pollination of our important agricultural crop flowers, leading to a decreased yield or quality of the food crop, Insect pollinators are needed for 35 percent of all food production globally – or one of every three bites you eat.

Although most Bluegums have been declared as an invasive species in South Africa, Beekeepers are highly dependent on eucalyptus and if they are all removed because they are aliens it would mean a serious shortage of food for bees – with a knock-on effect on crop pollination.

Because of this, the Department of Environmental Affairs’ legislation on alien and invasive species, updated in 2014, is “nuanced” for eucalyptus trees, not requiring all of them to come under the axe or chainsaw.

Eucalyptus is the most widely planted hardwood genus in the world, covering more than 19 million hectares. South Africa relies heavily on plantations of exotic forestry species, particularly Eucalyptus, to meet its timber needs.

Eucalyptus is a diverse genus of flowering trees and shrubs belonging to the myrtle family, Myrtaceae. There are no indigenous eucalypts in South Africa, but they play an important role in our ecology, especially to the Bee-keeping industry. Bee-keepers need a supply of forage (food) for their colonies throughout the year. Because Eucalyptus flower at various times of the year, they provide a constant and reliable flow of nectar and a source of pollen, making them essential to the bee-keeping industry.

South Africa’s honey bees are under threat. They face diminishing habitat and forage resources, attack by the Varroa mite pest and American Foul-brood disease, pollution from pesticides, and stress from being worked hard to provide a pollination service. For honey bee populations to withstand these stresses, a healthy diet is critical for a fully-functioning immune system.

So next time you drive past a Eucalyptus tree, give a thought to the important role this tree plays in our landscape.

Hypericum perforatum

 St John's wort is the plant species Hypericum perforatum, and is also known as Tipton's Weed, Chase-devil, or Klamath weed and is widely known as an herbal treatment for depression. Indigenous to Europe, it has been introduced to many temperate areas of the world and grows wild in many meadows and in our South African gardens.

The flowering tops of St. John's wort are used to prepare teas, tablets, and capsules containing concentrated extracts. Liquid extracts and topical preparations are also used. Today, St. John's wort is used by some for depression, anxiety, and/or sleep disorders.

France has banned the use of St. John’s wort products. The ban appears to be based on a report issued by the French Health Product Safety Agency warning of significant interactions between St. John’s wort and some medications. Several other countries, including Japan, the United Kingdom and Canada, are in the process of including drug-herb interaction warnings on St. John’s wort products.
