Leucospermum ‘Naomi’

pincushion protea
Flaming balls of red-orange-yellow pincushion flowers on a plump lush shrub. Thrives in well drained soil with little fertilizer. Drought tolerant. No phosphorus.

info		 Parents of this leucospermum are from Mediterranean climates of South Africa, so it is well adapted to California, particularly along the coast. It appreciates good drainage, but is somewhat adaptable to heavier soil as long as it is in a sunny spot and watering is infrequent (once established).

Leucospermums will grow and look their best when watered deeply every other week to once a month during summer. With sharp drainage, they will tolerate even more water.

Growing Notes

Giving this plant all purpose fertilizer will kill it immediately! Generally fertilizer is not necessary. Leucospermums prefer a mildly acidic soil, and if your PH is on the high side, (one cause of yellowing leaves) you can add cottonseed meal, iron, or other mild acidifying fertilizer to adjust it. They appreciate nitrogen in the form of fish emulsion or blood meal, but never give them any significant phosphorus and avoid potassium.
Leucospermums have showy pincushion flowers at the branch tips in late spring through early summer. These flowers go through a range of color shades as they develop and are loved by hummingbirds. They are a choice cut flower and the long straight stems make them perfect for display. Once flowers are mature they shed cleanly from the plant on their own.
Naturally pincushion proteas have a thick bushy form, but they can be kept smaller and made even bushier by pruning. Don’t prune more than two years of growth (where the old woody leafless stems start), or you risk the plant not budding back. They can even be groomed into modest-sized formal hedges.
Avoid clay soil, where the success of this plant is erratic. That said, if you just gotta have it amend the soil heavily with mineral content, such as pumice. Planting on a mount or slope is also helpful.
