Jane Hedreen and David Thyer live in Seattle’s Capitol Hill in a grand 1910 house that takes up six city lots and was once occupied by a US senator. Join us on a tour of their atmospheric gardens, which speak of another century.

N.B.: To see the interiors, go to An Impossibly Grand House in Seattle.

Above: A pair of blue atlas cedars, planted when the house was built, form a towering, moving screen over the front walk.

Above: The house came complete with a dreamy if neglected walled garden. Jane added an irrigation system as well as trimmed box and yew hedges for privacy. On her wish list: a lap pool down the middle.

Above: The south side of the house has an orangerie, a leaded glass plant bay, off the dining room. The exterior is flanked by Japanese maples.

Above: Unearthly looking podophyllum by the kitchen door.

Above: The garage/carriage house is thick with Boston ivy and other greenery, including a bed of gunnera and podophyllum in the sunken garden's old fountain.

Above: Jungly castor bean foliage.

Above: An indoor view of the orangerie planted with small olive trees, which have borne some fruit (Jane tried orange trees, but they succumbed to scales). It has a Tiffany tiled floor in bright blues and golds.

Above: Jane's youngest daughter, Frances, 11, mans the front steps in a Flora and Henri silk Fancy Dress made in Spain (the line's sizes go from newborn to 12). The house's Italianate details, such as the stuccoed arched entry, Juliet balcony, and colonnaded French doors, are courtesy of a remodeling that took place in the 1920s for a senator who wanted a Palladian villa.
