The NBG rock garden was created in the time period between 1961 and 1965 after the project of I. Davidsone and A. Pone, and in general saved its view until now. Plants are arranged in several terraces and are standing out sharply with beautiful flowers starting from the early spring. Here visitors can become acquainted with more than 400 plant taxa, including interesting perennials, rare bulbous plants, small shrubs, etc.
