Berberis thunb. ‘Pygruzam’ PYGMY RUBY features small, oval leaves that emerge bright crimson in early spring. Throughout summer, the leaves deepen to ruby-red before turning rich burgundy and bronze tones in autumn. The plant develops a neat, dome-shaped form with slender, arching stems covered in sharp spines. Its slow to moderate growth rate ensures that it retains a tidy profile without frequent trimming.

Flowers & Blooming

In April and May, clusters of small, cup-shaped yellow flowers appear along the stems. While individual blossoms are subtle, they collectively create a delightful contrast against the vivid foliage.
