Hebe 'Katrina' (Addenda Series)

Common name: Addenda Series Hebe, Shrubby Veronica

Description: The Addenda series represents a collection of compact, hardy hebe cultivars specifically bred for improved cold tolerance and garden performance in cooler climates. These evergreen shrubs feature dense, rounded habits with small to medium-sized, glossy green leaves arranged in opposite pairs along the stems. The series is characterised by profuse flowering from late spring through to autumn, producing dense spikes of small, tubular flowers in various shades including white, pink, purple, and blue depending on the specific cultivar within the series. Popular varieties include 'Addenda Blue', 'Addenda Pink', and 'Addenda White'. These hebes maintain neat, compact forms that rarely require pruning, though they respond well to light trimming after flowering. The series shows excellent resistance to common hebe problems and demonstrates superior winter hardiness compared to many traditional hebe varieties.
