Protea obtusifolia

Protea obtusifolia is a vigorous, robust species forming a rounded shrub and is easily raised from seeds. It  is a relatively long-lived, large bushy evergreen shrub and does well as a screening or informal hedge plant. It produces beautiful, long-lasting cut flowers during the winter months, still looking good after 20 years. Unlike most proteas it thrives in clay and alkaline soils. It is equally at home in acidic ‘fynbos’ soils. It is also tolerant of coastal conditions and withstands salt-laden winds. It is drought tolerant and requires little supplementary watering when established. It requires protection from frost.
