´óÏó´«Ã½

All is not lost: talks are underway to open the original garden as part of a neighbouring park. And a roof garden is being created at Blue Peter's new Manchester headquarters – to be unveiled this autumn.

Other news: pity the poor gardeners at Alnwick, Northumberland, who waited seven years for their giant Himalayan lilies to flower only to have them toppled by torrential rains.

And, in what's becoming my regular slot on large and unlikely animals in gardens: wallabies and raccoons are mere greenfly compared to this week's mega-pest.

Gary Long, head gardener at , near Truro in Cornwall, thinks he's spotted the legendary prowling through the shrubberies. A fleeting glimpse of a 'large, black cat-like creature' was followed by the discovery of mysterious claw marks an inch thick on the trunk of a rare Japanese shrub, Clethra barbinervis (it's a well-known fact that pests only trash the things you most want to keep). Now that's a garden pest too far.

Meanwhile , designing small garden 'Cinema Paradiso', has been panic-buying cushions (Shepherd's Bush market and a certain cut-price furniture store have stepped into the breach). reveals the Rousseau painting behind a scene in her conceptual garden 'Picturesque'; and I can't wait to see what arch of goat's rue (Galega officinalis) looks like.

Catch all the Hampton Court highlights on ´óÏó´«Ã½2 from Monday night; and on this very blog we've got guest posts appearing all week from, among others, , Rachel de Thame, and the irrepressible . All the après-show your heart could desire.

Out and about...
Tickets for Hampton Court are available from the or on the gate, and the show opens to RHS members only from Tuesday and to everyone from Thursday till Sunday.Ìý The special on Monday includes live music and fireworks over the Long Water; tickets are limited and selling out, though, so get your skates on.

After the show, if your feet aren't too sore, head into London for at the Garden Museum. Over 20 leading gardeners, designers and writers have planted up large pots for auction to raise money for the Museum's horticultural internship programme; among those whose plant combinations you can admire (and nick for your own containers) are this year's Chelsea winner , Lady and .
