Protea 'Pink Ice' is an evergreen shrub bred from Protea compacta and Protea neriifolia, grown for large goblet shaped pink blooms held above narrow grey green leaves. The habit is dense and upright, and the flowers last for weeks on the bush. It is the most dependable of the garden proteas.
It needs full sun, open airflow and sharply drained, slightly acidic soil, ideally sandy or gravelly. Warm temperate, Mediterranean and coastal climates suit it best, and it handles salt wind well. Once established it is drought tolerant and takes light to moderate frost. Use only low phosphorus fertiliser, since proteas resent phosphorus.
Plant it as a feature shrub, in coastal and water wise gardens, on embankments or as a low informal screen. It is also a serious cut flower, holding form and colour in the vase far longer than most. For a difficult sunny site with poor soil, there are few better performers.
Frequently Asked Questions
About Protea 'Pink Ice'
What is Protea 'Pink Ice'?
Protea 'Pink Ice' is a hardy evergreen shrub, a hybrid between Protea compacta and Protea neriifolia from the South African Proteaceae family. It is known for large, long lasting pink flower heads and narrow silvery grey green foliage. Of all the garden proteas it is the most reliable across a range of Australian conditions.
How big does Protea 'Pink Ice' grow?
It generally reaches around two to three metres tall with a spread of 1.5 to two metres, forming a dense upright shrub. Regular picking of the blooms keeps it more compact and encourages branching. In poorer, drier soils it will sit at the lower end of that range without any loss of flowering.
When does Protea 'Pink Ice' flower?
It flowers from autumn right through to spring, roughly March to November, which is an unusually long season. The blooms open gradually and hold on the plant for weeks at a time. That winter flowering habit is a large part of why it is planted, since it carries colour when little else is out.
What soil and position does it need?
Full sun and sharp drainage are non negotiable. Sandy, gravelly or rocky soil on the acidic side is ideal, and raised beds or slopes help where the ground is heavy. Keep air moving around the plant. Never use standard fertiliser on it, since the phosphorus in most products damages protea roots.
Is Protea 'Pink Ice' frost and drought tolerant?
Yes to both, once established. It handles light to moderate frost without damage, which makes it workable in most temperate districts. Drought tolerance is genuine after the first couple of years, as the root system is adapted to dry, nutrient poor ground. Young plants still need reliable water through their first summers.
Is it suitable for coastal gardens?
It is well suited to them. Salt laden wind and sandy soils are close to the conditions it evolved in on the Cape coast, and coastal gardens often provide the drainage and airflow it wants. Avoid positions where it sits in a hollow with still, humid air, since that encourages root and stem problems.
How do I prune and care for Protea 'Pink Ice'?
Prune as you pick, cutting flower stems with a length of leafy wood attached to keep the bush dense. Do the main tidy up straight after the flowering season finishes. Water deeply but occasionally, mulch with a coarse material, and feed only with a low phosphorus native fertiliser in early spring if growth needs help.
