Protea obtusifolia (Limestone Sugarbush) - Well shaped shrub to 9 feet tall with rich dark green leaves and large flowers with tightly overlapping pinkish red petals in fall though winter with some flowers lingering into spring. Plant in full sun in most any soil including clay and alkaline soils. Once established this plant is drought tolerant, requiring little irrigation. This long cultivated Protea is noted both for its beautiful flowers and for its reliability in the garden with long life and great tolerance for coastal conditions and alkaline soils (as high as pH 8.4). It is a great choice as a screening or hedge plant. To encourage dense growth and good branching structure plants should be pruned at a young age. The one drawback of this species is that it is not particularly cold hardy and early frosts can damage new growth, flowers and buds so protection may be required if temperatures drop below 29 F. Short stems have made this plant less desirable as a florist crop but flowers are extremely attractive and hold well in the vase.

We also take into consideration observations in our nursery of crops of this plant, as well as of plants growing in the nursery's garden and those in other gardens. We will incorporate comments received from others and welcome getting feedback from anyone who may have additional information, particularly if it includes cultural information aiding others in growing Protea obtusifolia.
