Time Out says
The glass domes of the palm houses are a striking landmark here. The Botanischer Garten is rarely crowded and is a good place for a stroll or a picnic.
The three glass domes of the botanical garden's palm houses might make you worry about an alien invasion. But despite their exotic and often stunning appearance, all the plants inside the spheres appear to be earthlings. Take an early morning stroll across the vast grounds or just sit and relax for a while on a sunny afternoon. The botanical garden is rarely crowded and can deliver instant peace and happiness when you stumble upon a pretty flower or watch the branches of the old trees swing with the wind.
