I have the same thoughts about perennials too. Hope the lilacs all survive holly.
I've just got back from Wisley - the butterflies are still in the glasshouse so the main path was full of excited small children and buggies. We went for a walk in the woods along the approach road and by the A3 - I'd been there for the first time when I met Blackpuddingbertha there last year, and it's lovely despite the noise from the roads. There were lots of camellias, magnolias and winter-scented shrubs - and not many people. I suppose the planting is rather old-fashioned - there will be rhododendrons later in the year. Th camellias were mostly in a good state, which was a surprise as we've had some very sharp frosts recently.
All over Wisley they have been adding to the winter planting so there was lots to see, and to smell. I especially liked the contrast between a cornus 'Flame' and deep purple crocus. There were some lovely drifts of crocuses.
I was entranced by the winter garden by the lake - lots of coloured stems of various plants, as well as coloured foliage, and some flowers. The planting is very regular so at first I thought it was too stiff, but as we moved along the various colour combinations changed like a ripple, and it was just beautiful.
We did talk last year about a thread trip to the Hampton Court Preview Evening. This year it's Monday 4 July, 17.00-10.30, and costs £58.00. Is anyone up for it? This doesn't include food, and the options include taking a picnic, booking a restaurant there or taking pot luck and buying there from food stalls etc.
