Growing Griselinia Shrubs In The Garden
Griselinia is a tender evergreen shrub native to New Zealand that grows in areas with mild winters. It withstands salt spray well and is a good choice for coastal areas. Griselinia shrubs will tolerate cramped conditions but it needs rich soil that is not too dry. It produces purple berries in fall. Griselinia littoralis is grown for its evergreen foliage, which looks neat and tidy all year long. The shrub produces tiny greenish-yellow flowers in spring, but they are seldom noticed. Griselinia shrubs grows best in a south- or west-facing exposure with full sun. The shrub isn’t particular about the soil type as long as it is well-drained. It tolerates a wide range of pH, from acid to alkaline, but you should avoid extremes. Griselinia shrubs thrive in USDA plant hardiness zones 7 and 8.
Griselinia care is minimal once the shrub is established. Water it deeply during dry spells and fertilize once a year in early spring. Griselinia pruning to shape and control the size of the shrubs is best done in mid- to late spring. You will lose the season’s berries, but they aren’t particularly ornamental and only of value if you want to save seeds. Remove damaged or diseased twigs and branch tips any time of year. If allowed to overgrow, griselinia pruning of thick, hard wood becomes difficult.
