The Salvia Border at Kew is a wonder now. Hardly worth a look in mid-summer (though you can, then, find the plant labels, a job which is nigh on impossible now the growth is so generous – hence these are images only with no naming of names, this time at least) – but now, my oh my!

The length of the border, with the high wall of the Family Beds borders behind them, and the Rock Garden in front, is a riot of colour, shape, contrasting flower and leaf shape, fragrance (from the leaves of the black-current scented forms). Many are diminutive, no more than knee-high, with flecked-jewel coloured flowers. Others tower well over my head with magnificent inflorescences. The overall effect is brilliant and many people were taking in the display, the arching everything as well as the detail.

It will be looking good until the first hard frosts and then that’ll be it for the season. Many are of course hardy enough and some, evergreen in a mild winter, but the larger forms need to be tucked up somewhere a little kinder and warmer than a West London winter can afford them.
