Wall Barley

Flower: Wall Barley produces dense, bristly spikes up to 10 cm long, composed of tightly packed spikelets with long, rough awns giving a distinctly “furry” or brush-like appearance. Flowering occurs from May to July, and like most grasses, the flowers are wind-pollinated and not visually showy. Fruit: The fruit is a typical grass grain (caryopsis) enclosed by persistent bristles and glumes. The whole spike can detach in segments, aiding seed dispersal along paths, fur, or clothing. The bristly nature makes the fruit a nuisance for dogs or livestock, sometimes getting stuck in ears or fur. Leaves: Leaves are broad for a grass, flat, and greyish-green, with rough edges. The sheaths are also rough, and the plant forms loosely tufted clumps, often less than 60 cm tall. The ligule is very short and membranous.

Bird-in-a-bush

Flower: Bird-in-a-bush produces dense, tubular flowers in shades of pink, reddish-purple, or occasionally white, blooming in March to April. The flowers are about 2 cm long, spurred at the back, and grow in compact, upright clusters (racemes) above the foliage. Each flower has a distinct lipped shape, chara... Fruit: The fruit is a narrow capsule (technically a silique), about 1–2 cm long, which splits open when mature to release small, roundish black seeds. These seeds are sometimes dispersed by ants (a process known as myrmecochory), as they possess fatty appendages (elaiosomes) attractive to them. Leaves: The foliage is finely divided and fern-like, with a delicate, blue-green hue. Leaves are typically three times dissected, giving a soft, feathery appearance. They arise from the base and may partially wither by the time the flowers are fully open, as the plant is ephemeral and goes dormant after blo...
