I'm originally from Dublin but now live in Edinburgh What Is Detrol David Stone became head gardener at Mottisfont only three years after the rose garden's inception and has been there ever since, but next year, after 37 years, he's retiring. With the roses still in full bloom in this late-season year, I've picked David's brains. Which are his favourites, the ones that excel in their extravagant beauty, their perfume, their length of flowering, disease resistance; the ones unmissable for any of us with space for another rose in our garden? Based on his years of taking care of the collection, David has picked his three favourite roses for five different situations in the garden. Here are his choices.
