Much-branched glaucous-leaved annual 15 inches high.

Grows upright in a thin spike of fleshy glaucous short leaves on salt-marshes.

From a single submerged root-stock many branching stems emerge.

Only few have side-branches.

The leaves are short, half-round, flat on the upper surface and taper to a blunt tip.

Sometimes there are much shorter leaves a little like a bunch of bananas amongst fewer but longer leaves.

The flowers are green (sometimes purple or red) and petal-less, nestling in small bunches nestling in the axils of leaves, looking like miniature brussel sprouts when not opened.

More mature specimens are branched, taller with the leaves spread away from the stems to reveal opened flowers in the leaf axils.

When not quite open, the flowers have five bulges with the short yellow anthers just protruding from the top.

The five green 'petals' (actually tepals) only partially open to reveal five anthers with cream-coloured pollen just protruding.

The tiny flowers consist of 5 green curved tepals which only partially open, this is a hermaphrodite flower (bisexual) with both stamens and a stigma (somewhere hidden). The tepals persist into fruit partially concealing the fruit.

The bracts, leaves, tepals and stems are covered in minute whitish glands which exude salt, for although, like many salt-marsh plants, the plant cannot do without some nutrients in sea-water, it cannot tolerate having too much salt.

 The style of probably a female-only flower since no anthers are visible as well.


Some similarities to : Glasswort. From a distance Annual Seablite could be mistaken for Glasswort because it is much the same height, grows in much the same kind of places, and looks similar in that it is glaucous, and has a 'Wild West cactus' look about it (apart from the huge size difference).

It is a succulent halophyte occupying the upper parts of salt-marshes which don't get innundated with sea water with every tide. The flowers on the plants are a mixture of bisexual and female-only. In Autumn the plants turn purplish-red. It is an annual and grows only where it has access to salt, usually the upper reaches of salt-marshes, but like English Stonecrop (Sedum anglicum), can also be found growing along some roads that are frequently gritted with rock-salt.
