Clematis is a perennial, climbing vine with vigorous stems. The deciduous leaves are opposite, odd-pinnate (5 to 9 leaflets, one of which is terminal), with fragrant greenish-white flowers, the calyx is petaloid (resembles petals). The stamens and carpels are spirally inserted and the androecium is polystemone with introrse dehiscence. The fruits are achenes with feathery edges, that is to say they are surmounted by a silky appendage which persists for a long time on the plant, giving it a characteristic appearance in winter.
Plant your clematis, the root ball inclined towards the wall but away from it (20/30 cm) so that the foot is watered by the rains. Put a layer of manure at the bottom of your hole, and fill it with fairly light soil (if necessary add a little potting soil and/or heather soil).
Clematis do not naturally cling to walls, so it is essential to provide a trellis so that the branches can roll up.
The name grass aux gueux comes from the use of its irritating leaves by beggars to deliberately inflict ulcers on themselves in order to arouse pity.
