We have two triangular shaped flower beds (approx 6 msq) as part of a new house build which are located in crevices between the house and footpath. That side of house is north facing. As a soil depth of more than 8 inches won't be possible (due to house foundation, etc), can you suggest suitable planting within this bed with shallow roots - ideally something low maintenance, perennial, purple/blue blooms and if any evergreen foliage possible?
I have a large clump of Arum Lillies, I would like to move them. When should I lift them, and could I grow them from the seed heads.
My asters are blooming at the moment, but the leaves have a white film of them. What is the problem?
I bought a Dicksonia Antarctica in a pot of about 30cm diameter in late April. When I bought it, it had a few baby fronds emerging but these have since disappeared with the exception of one which hasn't really grown beyond 4 inches and is brown at the edges. I have kept in the pot so far and am doing everything I am supposed to by keeping it moist and in semi-shade. It was an expensive birthday present so I don't want to lose it!
Could you please tell what the disease on this Phygelius aequalis "Sensation" might be. I haven't seen any pests on plant so have sprayed it with fungicide and tried cutting it back but it returns every year. Another phygelius - capensis - has it to a lesser extent while a third one "Moonraker" is disease free. I would appreciate your opinion.
I posted this picture on the Garden Club but we cannot agree on what this pretty flower is - the flower is very like both Malva and Sidalcea but the leaves are not like either. It is about 40cm high. The stems are hairy and the leaves are sort of furry. I don't remember buying it, but may have got it from one of my gardening friends. It is driving me mad not knowing the name of it.

I have four Agapanthus plants which have been in the same spots for more than 10 years. They were all huge. They appeared to be completely dead up to recently but now 2 of them have sprouted, but only one or two sprouts per clump. Will the others recover and was it the frost did the damage?
