A
Spring is just around the corner, but if you are tired of sunflowers, tulips (郁金香) and other standard gardens, why not head to one of these mysterious and wonderful botanical gardens？
Butchart Gardens, British Columbia, Canada
One of the rarest flowers you’ll find at Butchart Gardens is the Meconopsis, otherwise known as the Tibetan blue poppy. The most impressive flowers can be found in the borders, where you’ll find over one million bedding plants. And although the gardens are famous for their perennials (多年生植物), 300,000 spring-flowering plants are grown every year, and over 900 varieties of plants are grown for the summer gardens alone.
Kirstenbosch National Botanical Garden, Cape Town, South Africa
Kirstenbosch National Botanical Garden is one of a handful of botanic gardens to grow only native plants. Some of the most popular varieties include the king protea, which produces enormous flowers between autumn and summer, and the rare silver tree, a silky-leaved plant, which experts believe could become extinct in the next 50 years.
Denver Botanic Gardens, Colorado, US
Once native to South Africa, these oddly-named flowers are famously drought-hardy, making them perfect for this part of North America. This garden is one of the few to focus on draught-tolerant plants from Colorado and the grasslands of Africa, Mongolia and Argentina. In fact, Colorado is home to nine species of endangered plant, and several can be found here.
Arctic-Alpine Botanic Garden, Tromso, Norway
Visit the world’s northernmost botanical garden and you’ll find a breathtaking collection of plants from the world’s polar and mountainous regions including, in the Himalaya section, the rare giant Tibetan blue poppy, with its huge flowers and metre-high stem. You’ll also see the Wilander buttercup, which can only be found in the quite terrible areas of Svalbard’s unforgiving icy islands.
