OTish: 20 most widespread "weeds"
I've been making notes about the local flora. Should this be of mild
interest, these are the 20 most widespread (not necessarily the commonest) species - the figures in brackets are the number of "sites" in which they are present, where a site averages about a square kilometre. No grasses, as I can't tell them apart. There are also biases against late-flowering plants, and arable weeds, so take the figures with a pinch of salt. 1. Nettle - Urtica dioica (93) 2. Cleavers - Galium aparine (89) 3. Creeping Buttercup - Ranunculus repens (75) 4. Elder - Sambucus nigra (75) 5. Dandelion - Taraxacum officinale agg (73) 6. Hogweed - Heracleum sphondylium (72) 7. White Clover - Trifolium repens (71) 8. Broad-leaved Dock - Rumex obtusifolius (65) 9. Cow Parsley - Anthriscus sylvestris (63) 10. Daisy - Bellis perennis (63) 11. Bramble - Rubus fruticosus agg. (62) 12. Sycamore - Acer pseudoplatanus (61) 13. Common Ragwort - Senecio jacobaea (60) 14. Creeping Thistle - Cirsium arvense (59) 15. Ribwort (Plantain) - Plantago lanceolata (59) 16. Garlic Mustard - Alliaria petiolata (57) 17. Foxglove - Digitalis purpurea (57) 18. Ash - Fraxinus excelsior (57) 19. Spear Thistle - Cirsium vulgare (56) 20. Rosebay Willow-herb - Chamaerion angustifolium (55) -- Stewart Robert Hinsley |

It's rather more sensitive to conditions than most people realise; it needs part shade and either short grass or very little ground cover. As that is precisely what most gardens provide, it is a major pest there, but it isn't all that universal in the wild. However, I am extremely surprised at the lack of field bindweed, but it is extremely easy to overlook unless it is flowering. Regards, Nick Maclaren. |

writes I was surprised that hogweed was so near the top. So was I. It doesn't grow in great colonies, but it appears that it grows just about anywhere. -- Stewart Robert Hinsley |

writes Do you mean the little pink one or the big white one? The little pink one is field bindweed (Convolvulus arvensis), so I presume that's what Nick means.. The big white one is large bindweed (Calystegia silvatica). The less big white one is hedge bindweed (Calystegia sepium). The big pink one is hairy bindweed (Calystegia pulchra). The very little whitish one is black bindweed (Fallopia convolvulus), a relative of Japanese knotweed. The little pink one seems to like relatively light dryish soil., the big white one is happiest when it has something to climb up. It may be that much of the soil round here is too heavy for field bindweed - there's a lot of boulder clay about. -- Stewart Robert Hinsley |

"No grasses, as I can't tell them apart." Couch grass is recorded from my allotment and my garden, because I weed out the roots, but elsewhere it is overlooked. I don't think most people would recognise it apart from its roots. It's a very striking plant when in flower. Well, relatively speaking, for a grass ;-) -- Kay |
