Hall Road (Crosby) coast and dunes

Leader:  Mary Dean

After a long, dry and warm spell, twenty-four members braved the drop in temperature and strong north-westerly winds to meet at Hall Road to explore the botanical interest along the manmade shingle and the stabilised dunes between Hall Road and Hightown.

Close to the car park we saw Cochlearia danica (Danish Scurvy-grass), Armoracia rusticana (Horse Radish) and Beta vulgaris ssp. maritima (Sea Beet) and discussed the merits, or otherwise, of Sea Beet as a vegetable, recommended by one member as an alternative to spinach. On the brick shingle two large plants of Crambe maritima (Sea-kale) looked magnificent in full flower.

Other plants seen on shingle or the flattened dunes included Honckenya peploides (Sea Sandwort), Lotus corniculatus (Bird’s-foot Trefoil), Medicago lupulina (Black Medick), Trifolium dubium (Lesser Trefoil), Silene vulgaris (Bladder Campion), S. latifolia (White Campion), Vicia hirsuta (Hairy Tare), V. sativa (Common Vetch) and both pink- and white-flowered Rosa rugosa  (Japanese Rose). A large shrub of flowering Lycium barbarum (Duke of Argyll’s Teaplant) provided a temporary and welcome windbreak. Further on we found a solitary Smyrnium olusatrum (Alexanders), a plant several people had not seen at this site on previous visits, and a large patch of Cymbalaria muralis (Ivy-leaved Toadflax). 

Turning inland for an early lunch break in the shelter of the pumping station wall, we saw Geranium sanguineum (Bloody Crane’s-bill). After lunch we saw G. dissectum (Cut-leaved Crane’s-bill), followed by Hypochaeris radicata (Common Cat’s-ear) which we compared to and separated from Leontodon hispidus (Rough Hawkbit). 

Continuing up the coast the plants included Reseda lutea (Wild Mignonette), Avenula pratensis (Meadow Oat-grass) looking particularly splendid, Rosa spinosissima (Burnet Rose), Glaucium flavum (Yellow Horned-poppy), Euphorbia paralias (Sea Spurge), Crithmum maritimum (Rock Samphire), Parietaria judaica (Pellitory-of-the-wall) and Eryngium maritimum (Sea Holly), although not all were yet in flower.

Turning back and following a more inland route we came across a damper area with Thalictrum flavum (Common Meadow Rue) and Angelica sylvestris (Wild Angelica). On the drier areas were Asparagus officinalis (Garden Asparagus), Geranium pyrenaicum (Hedgerow Crane’s-bill) and attractive annual dune grasses Phleum arenarium (Sand Cat’s-tail) and Vulpia fasciculata (Dune Fescue).

Speeding up to get back before the rain a few naturalised species were found: a lovely show of Euphorbia cyparissias (Cypress Spurge), Polygonatum multiflorum (Solomon’s-seal), Spiraea sp. (Bridewort), Ribes rubrum (Red Currant), Papaver pseudoorientale (Oriental Poppy) and Syringa vulgaris (Lilac).

Just before returning to the car park we found several flowering plants of the rare endemic Coincya monensis ssp. monensis (Isle of Man Cabbage).

The field trip finished just in time for the eleven members who stayed to the end to remain dry. Fifteen minutes later it was raining heavily. My thanks for everyone for helping out with finding plants of interest, identification and tips for identifying the difficult ones.
