This is the time of the year when the Vachellia (formerly Acacia) karroo comes into its own. Also known as the sweet thorn (soetdoring in Afrikaans), this beautiful tree brightens the drought-stricken environment in the early summer with its bright show of fragrant yellow flowers shaped like tiny pompons which attract numerous insects.

The common name, sweet thorn, comes from the gum which is exuded from wounds in the bark. Although I have not tried it, the gum is reputed to taste pleasant enough to be eaten both by people and animals.

The trees are characterised by sharp white thorns that can grow to considerable lengths.
