An introduced foreign, low-growing and sprawling plant which, given the opportunity, spreads over large areas by rooting at the tips. Older leaves are weakly pinnately 3 or 5-lobed. Younger leaves are simple, finely-toothed and ovate.

Leaves a darker shade of green and shiny on the top surface.

Unusually, this branch is clambering upwards, but they usually sprawl horizontally.

A branch in search of somewhere new to root (which it does at the tip).

Stems red or green, with a dense covering of softish, reddish and narrow but tapering hairs rather than prickles or thorns.

Rear of leaves unexpectedly very pale creamy-green.

Veins of leaves either reddish or green, but always covered in (shorter) fine reddish hairs.

Here green veins, but hairs still red.

The teeth of the leaves have even shorter reddish tips.

Your Author took many photos of these thinking they were the flowers, but they are not: this plant very seldom flowers! It is an ornamental garden plant to cover vast areas of expanse. The curved-over reddish tips are where new leaves are forged.

New leaves being created at the tip of the growing reflexed tip.

When, if ever, it decides to flower, it flowers in racemic clusters. Your Author has still never actually seen it flowering, but these are the results of fertilised flowers. The plant is not self-fertile, which is why it seldom flowers.

Five long, tapered pale-green sepals covered in long reddish hairs on the outer surface envelop the flowers, but fold back to reveal the bright-red fruit.

The anthers are still present, albeit brown and spent on the edge of this orange collar.

Like Raspberry, Blackberry and Dewberry, the fruit is a drupe, developed from the many ovaries in a single flower - one of several kinds of aggregate fruit. [Strawberry, on the other hand, is not a drupe, but is an aggregate, formed from the receptacle of the that holds the ovaries and not from the ovaries themselves, where each achene on the outside (which looks like a 'seed') is one of the ovaries of the flower with the actual seed inside that].

The fruit of Chinese Bramble is a translucent-red (like the glace berries of Guelder-rose), with the remains of a long thin stigma still hanging off each 'fruitlet'. They are juicy and sometimes edible.


Uniquely identifiable characteristics

Distinguishing Feature : Spreads enormously and has the characteristics described under the photo captions.

This is a neophyte - an introduced alien species originally from China but now widely planted by gardeners who then often regret installing it since it spreads everywhere, and well beyond their own boundaries. It hardly ever flowers, so the attraction must be in the ability to spread and cover large areas fast, which it accomplishes with aplomb. It is a low-growing plant, self-rooting at the tips. The flowers are white if the reader ever gets to see them, your Author has still not. The berries are even more elusive, requiring fertilisation of the rare flowers and the plant does not self-pollinate. The leaves are semi-deciduous.

It is spreading fast and should, if it is not already, be on the incredibly invasive species list.
