If rhododendrons are your thing, there is a Japanese garden near here, at Tatton Park, which has to be seen to believed with its spring show of azaleas and rs. It is stunning.

I bought and planted more dwarf evergreen azaleas this year, which have all been successful, but am already looking forward to next spring when they will be in full flow and show. I think azalea is my favourite shrub.

Yesterday the wind was too strong and blustery to tempt me into grass-cutting activities, but I can't leave it much longer (and it's just as strong here today)
