樹齢・幻想的

150 years old: from an article about the beautiful flowers and lighting of the 150-year-old wisteria tree at Ashikaga Park in Tochigi — a good place to visit during Golden Week:

夜には樹齢150年を超える［大藤］がライトアップされ、約16万の花房が咲き、紫色の幻想的な雰囲気に包まれていた。

At night, the great wisteria tree, over 150 years old, is lit up — about 160,000 clusters of blossoms wrapped in a fantastical purple atmosphere.
