Biggar Park has a garden of approximately ten acres with the house situated in the middle. The garden is 700 feet above the sea level and is very susceptible to early and late frosts. There is a good collection of hardy hybird Rhododendrons and Azaleas in a woodland setting, flowering early June followed by groups of several species of Meconopsis. The season starts with a carpet of Fritillarias and then banks of Daffodils. By June the wall garden begins to show its potential with the early Herbaceous plants in large borders designed in a Saltire cross with vegetables and soft fruit behind a typical working wall garden with greenhouse and parterre. By July the shrub Roses, mainly old varieties, are in flower at strategic places throughout the garden. Other features include an Italian garden, rolling lawns and Ornamental Pond.
