The Rock Garden is a botanical garden at 6 Riccarton Avenue in Christchurch Central City, rated 4.4 from 19 Google reviews. Visitors describe a serene lake, colourfully reflected trees, beautifully maintained beds and a rockery that one reviewer called their favourite quiet corner of the park.
Botanical gardens are working plant collections rather than just ornamental parks: beds are labelled, trees are planted for decades ahead, and specialist areas such as rockeries are built to display alpines and other small plants at eye level, tucked among stone. They repay repeat visits, because the display turns over with the seasons, from spring bulbs to lush summer borders and autumn colour by the water. Regulars walk rock gardens slowly, since much of the interest sits at ankle height, and head for the quiet corners beyond the main lawns.
In the heart of central Christchurch, it makes an easy, unhurried stop, and the quiet rockery corner is the bit to look for.
