The Lady Walpole. Roses at Mannington.
Against the hall itself are two Banksian roses, lutea and lutescens which have grown so large that they obscured the light from the upper windows and have had to be cut back drastically. This revealed an exciting discovery - a new rose now named 'Mannington Cascade' which was featured on Peter Beales' Gold Medal winning 1999 Chelsea stand.
