Stanmore Country Park Nature Trail
Post 5: This is Spinney Field, a narrow grassy ride that is rich in meadow wildflowers. In April, May and June look for the violet-pink blooms of cuckoo flower Cardamine pratensis. Like all crucifers, the four flower petals are arranged in a simple symmetric cross. At the same time of year look for the orange-tip butterfly, whose caterpillars feed on cuckoo-flower. Males are unmistakable, with orange tips to their forewings, while females are all white.

From June to September look for birds foot trefoil Lotus corniculatus twining through the grass (see illustration below). The pretty yellow flowers are tinged with red as they emerge from the bud, giving the plant its alternative name of bacon and egg plant. There are in fact two species found here, the common birds foot trefoil and the greater birds foot trefoil which is distinguished by its hairy flower buds and leaves.

Look also for square stalked St John’s wort Hypericum tetrapterum (see illustration below). Like all St John’s worts this has attractive yellow flowers with five petals; the square stalk of this species is obvious when rolled between the fingers. In autumn the plant bears bright red berries. The trail now leads up the ride.
