Primula scotica

Tuesday 26^th June 2012                                                                        
11.00 – 14.00

Weather: little breeze, warm and plenty of sun.

Coastal Grassland:
Initially it appeared the grassland was dominated by Sea Arrow-grass and Sea Plantain but as soon as you got down on your hands and knees that closer look revealed all the plants that you would associate with coastal grassland. Sea Plantain came in all shapes and sizes; much of the path is composed of the tiniest of tiny plants – a sward of glossy green and fleshy leaves.

The Primula on the higher ground was barely in flower, this was in complete contrast to the more sheltered and sun-trap southeastern slope which was peppered with these minute gems. In ten days time the Primula show should be breathtaking.

Although we saw plenty of Spring Squill in flower, we saw far more of it in its seeding phase. It was a week or ten days too early for Grass of Parnassus – we saw a few ivory white flowers complete with their nectar guidelines. Wild Thyme was prolific in the areas of the thinnest soils and Martin found a white example for us to drool over.

Saltmarsh:

A lot of overlap here between the Coastal Grassland and the Saltmarsh. Plants on both habitats have the ability to tolerate saltwater drenchings. Little hollows in the coastal grassland revealed a few typical saltmarsh plants. The big surprise were the two Greater Sea-spurrey plants on salt drenched rocks in the Noust of Bigging.

Coastal Heath:

The heath is yet to flower. The Bell Heather was just beginning to get serious but the Ling was a long way off. Most striking was the abundance of Mountain Everlasting plants – it must find the granite soils to its liking. The stems, leaves and unopened buds of Slender St.John’s-wort trailed through the heath and will be in flower in a couple of weeks time.
