The flowers grow on a stalk, 5–10 cm tall, with four flowers facing outward to form a square, like the clock faces on a clock tower and a fifth flower facing upward to form the roof (the flower head is 6-10 mm across). The flowers are greenish yellow and the flowers facing outwards have 5 petals and 10 stamens and the flower facing upwards has 4 petals and 8 stamens. The pale green leaves are low growing but on long stems and each leaf stalk has three small-lobed leaflets.
