Arctium minus

Lesser Burdock Waste ground, hedge bottoms and grassy places.

Carduus crispus

Welted Thistle Rather uncommon, usually found as isolated plants or small colonies.

Carduus nutans

Musk Thistle Rather infrequent, on waste ground.

Cirsium vulgare

Spear Thistle Common on waste land and neglected grassy places.

Cirsium palustre

Marsh Thistle Only on Priory Road fields, not within city boundary.

Cirsium arvense

Creeping Thistle Very common in waste and neglected grassy places.

Centaurea scabiosa

Greater Knapweed Both records for chalky railway embankments, Springhead (02P) and Fountain Road (03V).

Centaurea cyanthus

Cornflower Rare, a single plant growing on the site of the old sidings east of Priory Way.

Centaurea nigra

Common Knapweed Frequent and often very abundant in grassy places and on old railway balast. Some of the plants growing on Rockford Field (13A) are very slender and have radiate florets - I feel sure that they must be of the subspecies nemoralis.

Lapsana communis

Nipplewort Very common on waste ground, ar roadsides and in hedge bottoms.

Hypochaeris radicata

Cat's-ear Common in grassy places.

Leontodon autumnalis

Autumn Hawkbit It is probably quite common; work later this season should produce more records.

Leontodon hispidus

Rough Hawkbit Found at a single site - the rubble bank at the end of Somerden Road.

Picris echioides

Bristly Oxtongue Often abundant in the areas near to the River Hull. Usually at roadsides and on waste ground - seen as a lawn weed on the North Bransholme Estate.

Tragopogon pratensis

Goat's-beard Frequent and widespread, grassy places.

Sonchus arvensis

Perennial Sow-thistle Waste and grassy places..

Sonchus oleraceus

Smooth Sow-thistle Found in every tetrad surveyed. Common everywhere at roadside and in bare waste places.

Sonchus asper

Prickly Sow-thistle Common and widespread but perhaps not quite so much as S. oleraceus - seen more often early in the season.

Lactuca serriola

Prickly Lettuce This is becoming a very common plant in Hull. It is found in all types of habitat but particularly waste places and roadsides.

Lactuca virosa

Great Lettuce During the preliminary survey several robust Lactuca plants were found. They tended to have more deeply lobed leaves and were strongly suffused with a maroon coloration on the stems and leaves. Examination of the seeds later in the season has confirmed this species at Summerden Road.

Mycelis muralis

Wall Lettuce Two plants, both in the Cottingham Road area. Shady gardens. A third on Clough Road.

Taraxacum officinale agg.

Dandelion Common in grassy places and as a weed in lawns and sports fields.

Crepis biennis

Rough Hawk's-beard Distribution not fully known yet.

Crepis capillaris

Smooth Hawk's-beard Widespread in grassland.

Crepis sp.

Hawks-beard Probably Crepis biennis, not fully determined yet!

Pilosella officinarum

Mouse-ear-hawkweed Uncommon on well-drained alkaline substrates, mainly railway ballast.

Filago vulgaris

Common Cudweed Found in June 1997 growing on Priory sidings. Locally abundant.

Pulicaria dysenterica

Common Fleabane Damp places. Old railway sidings to east of Priory way (02T,) near the Ennerdale Sports centre (03W), Holderness Drain (13F).

Solidago canadensis

Canadian Goldenrod Garden escape but very well naturalised.

Aster tripolium

Sea Aster Along the Humber shore and up the River Hull, never far away from the salt water.

Erigeron acer

Blue Fleabane Dry places with sparse vegetation.

Conyza canadensis

Canadian Fleabane Since this plant does not flower until August it seems likely that it has been under-recorded. Roadsides and waste places.

Bellis perennis

Daisy Anywhere with short grass, abundant.

Tanacetum parthenium

Feverfew Roadsides and waste places. Usually an escape from nearby gardens but some plants with no obvious source.

Tanacetum vulgare

Tansy Usually in grassy places - roadside verges etc.

Artemisia vulgaris

Mugwort Very abundant on waste ground everywhere.

Artemisia absinthium

Wormwood Single plant growing on a wall near the tidal barrage. R.A. Eades (Hull Natural History Society Newsletter 9)

Achillea ptarmica

Sneezewort Grows on Priory Road fields, outside city boundary.

Achillea millefolium

Yarrow Common on grassland and often on roadside verges.

Chrysanthemum segetum

Corn Marigold A single plant growing on an imported sandy soil along Spring Bank (the western extension of the road which is a footpath following the filled-in drain 1996. In 1997 again only a single plant found. This time outside the Mecca Bingo Hall, Clough Road. Several years ago many new flower beds were a blaze of golden yellow with this plant. Unfortunately it does not seem to persist for long.

Leucanthemum vulgare

Oxeye Daisy Dry, bare or grassy places.

Matricaria recutita

Scented Mayweed An arable weed found at roadsides and on waste ground.

Matricaria discoidea

Pineapple-weed Common alongside paths and in well trampled places.

Tripleurospermum inodorum

Scentless Mayweed Roadsides and waste places.

Senecio jacobaea

Common Ragwort Rather common in relic semi-natural grassland areas. Also drain banks and roadsides.

Senecio erucifolius

Hoary Ragwort Rather common on the heavy soils to the north east of the city.

Senecio squalidus

Oxford Ragwort Very common on waste land and at roadsides, particularly in the older industrial areas with disused railway lines.

Senecio vulgaris

Groundsel A common ephemeral weed on disturbed ground everywhere.

Senecio viscosus

Sticky Groundsel Infrequent, waste places and old railway lines.

Doronicum pardalianches

Leopard's-bane Naturalised in two different woodland fragments near Saltshouse road, 13G.

Tussilago farfara

Colt's-foot Widely distributed on waste ground throughout the city.

Petasites hybridus

Butterbur Near the junction of Bricknell avenue and Snuff Mill Lane (03K), a site known for over seventy years (Mrs Chaplin 1994, Hull Natural History Society Newsletter no 5). It probably grows on the Gas Works sports field to the south of Clough Road but this needs further investigation.

Petasites fragrans

Winter Heliotrope Near the Victoria Dock development - deliberately planted?

Helianthus tuberosus

Jerusalem Artichoke Western junction of Summergroves and Hessle Road, a relic of former cultivation. It is difficult to distinguish between this species and the Sunflower, H. annuus, without flowers (Jerusalem Artichoke rarely flowers this far north, 1995 being an exception) so the colony will need checking again in the autumn.

Galinsoga sp.

Gallant Soldier Rare, on imported soil outside Mecca Bingo, Clough Road. Could not be determined to species level.
