In April I bought a small plant of Artemesia californica while visiting the Artemesia National Collection in England.It is planted in a south-facing corner where two low walls meet and has grown into a very pretty plant with a shrubby base and many long 'arms' with fine leaves which have a delicate scent.So far my efforts to get cuttings to root have failed .Can anyone tell me if it is likely to survive short spells of 20c and a damp winter or should I try to move the whole thing indoors ?
