Meyer recommends taking the cable car to the top of New Zealand's Wellington Botanical Gardens and checking out the view of the capital city and harbor before you begin the downhill stroll through the gardens themselves. Many of the exotic species date back to colonial botanists in the 1870s, including conifers in their exotic forest and camellias from Southeast Asia. More telling of New Zealand's British ties is the large rose garden, mixing vintage and modern blooms. The spring highlight comes in late September to October, when more than 25,000 tulips bloom.
