Bud, Petal and Aunt Rosa - The Kewtees By Colin Hines Illustrated by John Hilder

Tiny, plump and gloriously green, the Kewtees find themselves
uprooted from their forest home in the strangest of circumstances. They have
to travel far and overcome many difficulties before they reach the safety of
the Temperate Greenhouse at Kew Gardens. Led by the resourceful Aunt Rosa
and helped by young Petal and Bud, the Kewtees plan to start a new life there,
away from the dangers posed by their old enemies, the cruel Vampees.
But will that be possible?
