Ok all you keen gardners here's one for you... We have a house in 47 that has a dry stream running through it .....currently has pebbles in the bottom that you can walk on, water about 1 foot below(ish)........with it so far....but on the sides I have put green membrane on it to kill off weeds - it approx 3 feet deep on each side and runs for approx 100 feet in lengh So on to the question - what shall I/can I plant into the membrane? It's clay soil, temperature wise - hot in summer and (very) cold this winter - I would love to create some colour and cover the green membrane too with plants that are perennial - but whatever will grow and suit the climate really I like to get stuck into the garden but am by no means an expert - all advice greatfully received Thanks Lou, Lot et Garonne
