  1. Powerscourt Gardens, County Wicklow

The sprawling estate of over 47 acres of formal and informal gardens can be found within the magnificent Powerscourt Estate.

During the Victorian era, the formal gardens that you see today were created.

Often referred to as the most ambitious garden project in Ireland, they combine sculptures, pools, fountains, and several plantings set up against a setting of woods, mountains, and river valleys in this beautiful part of Ireland.

The garden plans, which borrowed from Italian and Japanese garden styles, are in three volumes and can be found at the National Library of Ireland in the museum’s Reading Room.

The highlight of Powerscourt Gardens is its breathtaking waterfall, which cascades down the side of the Sugarloaf Mountain, creating a truly awe-inspiring sight, deservedly making it one of the 12 most beautiful gardens in Ireland.

The waterfall is the second highest in Ireland after The Devil’s Chimney in County Sligo.

It is also a great example of an authentic “Robinsonian” style garden ­— invented by William Robinson — that combines the collection of trees, shrubs, and flowers in a relaxed, informal way.

The garden was established in 1868 by Edward Walpole, who purchased a small track of land, only to later develop it into a garden with the help of his three sons.

They eventually filled the garden with rare plants from around the world, a common practice among the wealthy in Europe at the time.

The gardens themselves contain a variety of rare plants from China, Pakistan, Iran, South Africa, New Zealand, and Bhutan, all collected by the Parsons family (Earls of Rosse) on their travels around the world over the last 150 years.

Its claim to fame, however, lies in its world-record-holding box hedges, which stand at an astounding 68 feet/21 meters.

These towering emerald walls are located near the Hornbeam Cloister Walk, which was planted by Anne, Countess of Rosse in 1946 to celebrate her marriage to Michael, the 6th Earl of Rosse.

The reason it is called the Shamrock Garden is because some say, when viewed from above, the garden is shaped like a shamrock.

The autumn/fall season is the perfect time to visit Mount Stewart Gardens as everything bursts into color, with rich reds, oranges, blues (there are over 20 varieties of Eucalyptus tree there) and golds enhancing the space.

Look out for the double line of yew trees called “Addison’s Walk,” which survives from this period when the gardens were used primarily for research.

The gardens were the first location in Ireland where the potato blight fungus was discovered and that consequently ruined the potato crop across the country and caused the death of millions during what became known as The Great Hunger.

Throughout the years of the famine, researchers at the gardens tried their best to stop the growth of the fungus but to no avail.

Now managed by Ireland’s Office of Public Works, The National Botanic Gardens of Ireland houses about 20,000 living plants and millions of dried plant specimens.
