Hardly a secret, but an essential stop for those short on time and green fingers. Grab a white hydrangea, cyclamen or phalaenopsis orchid (the Hermes scarf of interiors). It has a strong line of its own grown topiary at very competitive prices, or browse the Zanzibar gems, gardenias, agaves, camellias, lavender and flapjacks. There are also planters, in everything from cement to terrazzo, matt black, glossy white and celadon. Half its pots are discounted. Knowledgeable and helpful staff.
