Yes, it is free, but it is worth exactly what you pay for it, meaning not much.Most of the things growing there are grass, low-growing junipers and pines, and foundation shrubs. If you are looking for blooming plants, other than a few annuals, you will be disappointed. There were no interesting perennials or unusual plants there when I visited one month ago (June 2017). I would recommend spending your time somewhere else.
Yes, it is free.
Opening hours vary according to seasons (e.g. 1.05- 30.09 it is open 8am-8pm).
Hi Linucz - yes it is open for free but it is closed before 8PM, so you have to plan it during a day.
