Beach primrose (Oenothera drummondii)

This Beach Primrose was colonising sand dunes just south of Cudgen Creek in Kingscliff NSW.

Beach primrose is a herbaceous perennial. It is a
very hairy plant which forms a silvery-green mat
on the surface of the sand. The stems are prostrate,
occasionally branched, widely spaced, and up to
50mm long. The silvery-green leaves are alternate and
closely crowded about the stems. Leaves and stems
both have a dense covering of small white hairs. The
leaves are 4-7cm long, 10-15mm wide, widest toward
the top and tapering towards the base.
Single flowers are borne in the leaf axils (the angle
between leaf and stem). At flowering time, each
plant produces two to twelve widely spaced flowers.
The flowers are bright yellow, 3-4cm across, and often
turn a reddish colour on drying out. Each flower has
four sepals, four petals and eight stamens, and is
situated on the upper rim of a tube (hypanthium)
which extends above the ovary.
Following pollination, the flower breaks off at the top
of the ovary, which then develops as a seed capsule.
The seed capsule is a thin cylinder about 4cm long
and about 2.5mm wide. At maturity the capsule
opens from the top downwards, releasing numerous
small seeds.
