First planted in 2000, this area takes its name from a planting scheme which concentrates on red, yellow, orange and bronze-hued herbaceous shrubs and climbing plants. These continue to flower until well into the first throes of winter thereby providing both colour and interest.

In 2006 The Telegraph wrote;

"Impressive as all this was, it was the hot borders that really blew me away. Reached across the spring garden, with its avenue of white 'Shirotae' cherries, underplanted with white bulbs and spotted-leaved pulmonarias, it runs for 300ft along a high, brick wall. The orchestration of textures and sizzling tints is among the best I have seen, with repeated hazy eruptions of flowering grasses leavening the more solid clumps of flower. Fat stands of 'African Queen' lillies, left undisturbed for four years so far, were pumping perfume from apricot trumpets, while the climbing rose 'Dublin Bay' was making swags of blood-scarlet against the wall.
