Grevillea are native to both Australia and South America which means it's probably about 130 million years old and lived on the Gondwana supercontinent! This subspecies of Grevillea victorea originated as a chance seedling at a nursery in Occidental, California and is named for the late owner Marshall Ulbrecht.
We planted ours on a south-facing slope in clay soils - with full sun exposure and cold winds in the winter. It was 2 ft. tall when planted and now, 5 years later, is over 10 ft. tall, 18 ft. wide and still growing. We rarely water it.

At the end of summer 2010, I planted a row of Grevillea Marshall, little scrawney one gallons. Now in 2013, they are the most complemented plant in my front yard, they are over 6 ft tall and very full and graceful habit. We get pretty cold here at night (20f and occasionally colder. My soil is red volcanic type and I fertilized them with quick start at planting. No fertilizer since and they are on drip irrigation. They could not be any healthier, the Hummingbirds LOVE them and they look just like Olive Trees only they are bushes. The best thing is that the herds of deer trooping through here don't eat them. YAY!!!
