I don't know if you have favourite bolt-holes, places that get you right away from all worries and cares, but mine is the Scilly Islands off the tip of Cornwall.

This autumn, I grabbed the opportunity to escape yet again. But I'm very happy to escape AND still think about gardening for wildlife.

For instance, one day, I was walking across the main island of St Mary's, and a flock of Greenfinches sprang from a front garden hedge of Rosa rugosa, the Japanese rose with the big fat hips.

Mmm, I thought, I've a good idea what they were up to. And here was the tell-tale signs:

The hips have been nibbled open to expose the real prize, the glut of white seeds in the middle.

It is so easy to imagine that fruits are nature's way of using wildlife to help disperse their seeds, but sometimes nature strikes back and targets the very precious seeds rather than the succulent fruit. Yes, Greenfinches are what Barbara and David Snow call 'seed-predators' in their ground-breaking 1988 book 'Birds and Berries'.

While on Scilly, I also couldn't resist another trip to the amazing subtropical gardens on Tresco. Here you get to see the most amazing plants growing outdoors that in most other parts of the UK would be knobbled instantly by the first frost.

So you can enjoy things like Proteas from South Africa, six feet high and covered in their giant blooms:

Spot the Honeybee burrowing deep into the bloom, on the lower left side - yes, if bees can get to the nectar, it doesn't matter whether the flower is from this country or from half way around the world.

But this plant was the No 1 Nectar Bar in the whole garden. Look at what a bumblebee and Honeybee magnet it was - amazing!

But I don't know what the plant it. It formed a tall shrub, maybe eight feet high, with foliage that almost looked like a conifer but with these strange clusters of white flowers.

So you've guessed the challenge - can anyone identify it for me? I need to know!
