The property, which features a country garden with hedgerows and roses, is understood to be opening to the public for the first time as part of the Blooming Tasmania scheme.

Couple Jennie Chapman and Stephen Caswell have owned the 45-hectare property for the past 21 years and at the beckoning of friends have finally decided to open the garden for the public to see.

The property dates back to the early 1800s and is believed to have been highly productive with a range of crops and sheep grazing.

When they bought the property, Ms Chapman said it was partially rundown but they had spent considerable time over the years to develop it and highlight views across to Drys Bluff and the Great Western Tiers range.

The garden comes alive in spring with roses and perennials, there is a crabapple walk, zen, family and vegetable gardens to explore and enjoy.

Blenheim Farm, 733 Cressy Road, Longford, will open on Saturday and Sunday from 10am to 4pm.

Cost is $6.

Grey Sands Vineyard will also open its garden this weekend, as a fund-raiser for the West Tamar Rotary Club, which will also hold a barbecue.

The garden features unusual conifers, shrubs and perennials.

The garden at 6 Kerrisons Road, Glengarry, will open Saturday and Sunday from 10am to 6pm.

Cost is $8.
