Asian lotus (ssp. nucifera) The garden created by Polish opera singer Ganna Walska is a truly extraordinary realm. Her labour of love over 43 years, it is a succession of contrasting "green rooms" and clusters of unusual plants. Topiary, dramatic displays of cycads and cacti, a Japanese pool, an open-air theatre, a beach set with giant shells…wonderful surprises appear at every turn. Private guided tours (visitor numbers are strictly limited) are available, reservations required.
