My little wild garden has: flag iris, cranesbill, nigella, st john's wort, speedwell, bluebell, forget-me-not, soapwort, daisy, fennel, rose (wild and cultivated) water-mint, barley, pimpernel, sorrel, wild garlic, soapwort, honeysuckle, tansy, yarrow, primrose, sweet violet, bracken, elder, teasel, nettle, woodruff, Welsh poppy, Queen Anne's lace, and various seeding grasses, in an area about four feet square.
My NDN likes her garden tidy and she keeps her lawn short. We like the wildlife that my riotous patch attracts, and so we had a chat and she asked if it was all right with us if she put up that weed-repellent membrane against the fence so that none of our wild flowers can get established with her.
So we're all happy!
