One of the most magnificent magnolias is the Pink Tulip Tree, or Campbell's magnolia (Magnolia campbellii), which in the Himalayas can reach the heady heights of 50m. It grows at an altitude of 2,500 - 3,000 m and is found in Nepal, east to China and south to Myanmar. However, despite its mountainous origins, this magnolia is used to some shelter and relies on a relatively mild spring.

Late frosts can adversely affect the chances of flowering and temperate conditions, including deep, moist soil, are important for young trees to become established. Named after the Scottish botanist Dr Archibald Campbell, it was introduced to Britain in 1868 and in cultivation rarely exceeds 20m.

The glorious flowers which appear before the leaves emerge in spring can be as large as 20cm across and create an unforgettable sight. This year they are particularly good due to the consistently cold weather which has prevented the buds from swelling too soon.
