Let’s walk to the Rock Garden today to see what is in flower there on a cool winter’s day.
- Olearia argophylla [Section 305], or Native Musk, on your right is a tall shrub or small tree with felted grey leaves and white, strongly-scented flowers. It is an east coast plant which grows naturally in NSW, Victoria and Tasmania.

- Turn right towards the Rock Garden, past the Wollemi Pines. Go up the steps to your left to notice on the left-hand side Grevillea lanigera [Section 15c] with grey-green foliage and pink and cream flowers on a low bush. This grevillea is very long-flowering and useful in the garden. It is commonly known as Woolly Grevillea, and is endemic to Victoria and New South Wales.
- Banksia integrifolia subsp. integrifolia [Section 15c], also on your left, is a vigorous groundcover with dark green leaves that have attractive silver backs. There are both mature and developing upright yellow-green cones on this versatile and hardy plant, which is native to coastal eastern Australia.

- Grevillea ‘Little Jessie’ [Section 15g], up to your right, is a hybrid between Grevillea asparagoides and G.calliantha. It is named after the daughter of the originator, Stephen Smart. It is a large open bush with grey-green needle foliage and cream/pink flowers with long red styles.

- Acacia alata var. platyptera [Section 15f] on your right has bipinnate flattened phyllodes and very large golden ball flowers. It is native to Western Australia.
- Cross the plank bridge and turn right down the hill to see Hakea obtusa [Section 15p] on your left, a small tree with leathery foliage and dark pink powderpuff flowers along the stems.
- Go to the bottom of the steps near the waterfall and then turn left up the other set of steps to see Alyogyne huegelii ‘West Coast Gem’ [Section 15r], on your right with clear purple ‘hibiscus’ flowers. The bush is medium-sized with coarse divided foliage.
