GREEN SPACE A newly installed rock garden takes the place of an old vegetable patch. This spring will be its first, and Hager eagerly awaits the show. 'We packed it with bulbs,' she says. Heathers, striped 'Color Guard' yucca, and burgundy-leaved Aloha lilies (Eucomis) are underplanted with tiny sedums in this area of the banking. Since they are not hardy here, all the Eucomis bulbs have to be dug up in the fall, bagged in dry peat and stored for the winter. 100 New Hampshire Home
