Ascreavie House was designed by William Scott of Dundee, a pupil of the Edinburgh architect, George Angus, in the mid-1850s. There are several garden Ornaments and Stone Urns, one of which is dated 1717. They were probably brought to Ascreavie by the Sherriffs. The old Kennels and other buildings are all used for storing garden materials. A Cottage is built on to the kitchen garden walls.
The small area of parkland to the south and east of the house is planted out with several clumps of broadleaved trees including oak, beech and a good copper beech dating from c.1850. Recent planting has been confined to the field to the south of the house where several unusual trees were planted by the Sherriffs. The field is now let for grazing.
There are extensive tracks of woodland between the Ascreavie policies and the moorland to the north. They have been replanted with conifers within the last 50 years. The small shelterbelt to the north and west of the house, protecting the garden, is planted mainly with conifers: Lawson cypress, Douglas fir and larch, some dating back to the mid-19th century. Broadleaved trees, especially oak, were planted in the glades by the Sherriffs. Between the drive and the kitchen garden they also planted another new shelterbelt, mainly of beech. Along the drive they also planted several exotic trees, in particular, species of Acer and Sorbus, including a Sorbus aria variegata.
The Sherriffs planted the garden around the house. Many of the smaller Rhododendrons and herbaceous plants were planted out on the formal terraces to the south of the house. All over the garden small troughs, sinks and other containers were filled with alpine plants, many of which have since gone.
The shelterbelt was carefully thinned to provide very attractive glades where Rhododendrons could flourish under the protection of the tree canopy. Narrow walks meandered through the glades, which were planted out with many interesting and unique species Rhododendrons, particularly those with attractive leaves. Other acid- loving small trees and shrubs were also selected for their unusual qualities and planted to show off their form. The garden gradually expanded northwards up the slope as the collection grew. Further small terraces were planted up and more winding walks showed off the plants. The Primulas were mainly grown in a special garden near the house. An unusual beech and Lawson cypress hedge marked the end of the garden. To the east, another glade of the large leaved Rhododendrons led towards the kitchen garden.
The conditions for each plant were carefully chosen or contrived, and it must have been a delightful and very special 'connoisseurs' garden. There were too many noteworthy plants to identify here but the following illustrate the range: Tropaeolum speciosum, a large Daphniphyllum macropodum, Daphne 'Rosetti', Rhododendron tsariense, R. longistyllum, a good specimen of R. campylocarpum, R. lapponicum triflorum, a magnificent plant of R. orbiculare, two large Eucryphia glutinosa and a fine Himalayan birch (Betula jacquemontii).
The kitchen garden appears on the 1st edition OS map as a kitchen/flower garden and it is still partly used today. Walls protect it on three sides and a low holly hedge runs along the south section. In the centre, a circular yew hedge leads to a pair of red cherry hedges (Prunus pissardii 'Atropurpurea') divided by a hedge of Rosa spinosissima dating from the Sherriffs' time. There is still a glasshouse and some fruit trees along the walls. Recently most of the garden has been allowed to run down.
