Casting around for what to do with the front garden, I decided on a pergola overgrown with climbing flowers and fruits. Clematis and loganberries seems an ideal combination. But then I can also plant flowers in the spaces between the legs of the pergola for ground cover and colour, so what to plant?
I was looking at blues and purples when I stumbled upon Hydrangeas. They look lovely, but further research reveals that kids have started nicking the flowers to smoke 'em on the basis of a myth that they contain tetrahydrocannabinol, the active ingredient in cannabis. They don't contain any THC but they do contain Hydrogen Cyanide, the famous Nazi death gas. Now while there isn't enough HCN in a Hydrangea spliff to kill you there is enough to risk brain damage.
A combination of conscience and the fervent desire to not have my garden trashed (again) is why I'm not planting Hydrangeas until this idiocy dies a death. A shame really, because they do look lovely!
