In evolutionary terms, gardening purely for pleasure and decoration is very recent. Before then it was about growing herbs for medicines and food to eat. Gardening for pleasure took off when the growing middle classes wanted pleasure gardens which had, hitherto, been solely for the nobility with space and money to indulge.
Plants have been brought here for centuries and even millennia by invaders and migrants and traders and then by plant hunters and importers serving a market.
I spend hours weeding out creeping buttercup, fat hen, nettles, bindweed, thistles, bittercress, couch grass, groundsel, iris pseudocorus and boggy sedges because they are invasive and ugly and I want colour and form from plants with more visual interest throughout the year to provide food and habitat for wildlife.
