Topics and leaders for term 3, 2017

July 24th

Leader: Michael Griffith
Topic: ‘Grevilleas and Hakeas (Family Proteaceae) ’
Background:

Grevillia flower

Both red and grey spider flowers are in abundance in Sydney sandstone bushland in late winter and early spring, and we may spot pink or white spider flowers growing among rocky outcrops. These Grevilleas are easy to learn to recognise and are part of the Proteaceae family of plants. In comparison, the Hakeas have small, light coloured flowers but bear large, woody seed capsules that persist on the shrub for many years. Their fruit aid greatly with their identification. As we walk around the Ku-ring-gai Wildflower Garden after the talk, we will recognise many of these plants and learn more about where they grow and their common characteristics.


July 31st.

Leader: Margarita Clayton
Topic: 'Boronias and other Family Rutaceae'
Background:

Eriostemon flowers

Have you ever wondered about the pink flowered plants that make such a show in the bush from late winter through to spring? Come and enjoy seeing the local species of Boronias and the elegant pink wax flower, Eriostemon australasius. Many species in the Rutaceae family attract birds and an interesting range of insects including solitary bees, flies, moths and ants.

August 7th.

Leader: Robert Failes
Topic: ‘Acacias (Family Fabaceae, Subfamily Mimosoideae) ’
Background:

Acacia flowers

Acacias - or wattles as they are commonly known - are one of Australia's most important and best-loved plant groups. Their common names such as Sunshine Wattle conjure-up cheery visions of green and gold. The Golden Wattle, Acacia pycnantha is Australia's national flower. Acacias are used by Aboriginal peoples for food, weapons, tools and ornaments. They are easy to grow and grow rapidly. We'll look at the many local species and some planted Acacias as we walk around the Ku-ring-gai Wildflower Garden after the talk.

August 14th.

Leader: Alec Fisher
Topic: ‘Climate change - effecting flora and fauna ’
Background:

 

August 21st.

Leader: Jan Marshall
Topic: ‘'Heath plants (Family Ericaceae)’
Background:

Sprengelia incarnata flowers

Some of our most beautiful native plants occur in the poor soils found in the coastal heaths of Eastern Australia. Styphelia tubiflora (Five Corners) is one of these. Others growing in the Sydney region include Epacris longiflora (Native Fuchsia), Woollsia pungens and various members of the Leucopogon genus (the Beard-Heaths). These plants are members of the Ericaceae family. Many heath plants occur in Ku-ring-gai Wildflower Garden and will be seen in flower in this session.

August 28th

Leader: Helen Theile
Topic: 'Pea (Family Fabaceae)'
Background:

Pea flowers

This is a very large group of plants occurring widely in the northern and southern hemispheres. Domesticated varieties are major foods: green peas and beans, peanuts, soya beans and grain legumes. Most local species have yellow flowers with a splash of red but some of the climbers come in dark reds and vivid purples. They are also a favourite food of the local wildlife. The talk will be complemented by a walk to see flowering examples within the Ku-ring-gai Wildflower Garden.

September 4th

Leader: Bill Jones
Topic: 'Orchids (Family Orchidaceae)'
Background:

Beard Orchid Flower

There are over 35 species at Ku-ring-gai Wildflower Garden! However they are mostly ground orchids and often hard to find because they flower irregularly. Learn about these attractive, fascinating plants and their unusual features and requirements. Join Bill Jones to find out about these interesting plants.

September 11th

Leader: Robert Failes
Topic: 'Some other Families of Dicots in KWG'
Background

Pimilea flowers close up

When considering native plants some commonly occurring ones often get overlooked. In this session, some of these plants will be considered. They have these rather intriguing common names(!!): Cheese Tree, Wedding Bush, Bleeding Heart, Trigger Plants, Black-eyed Susans, Rice Flowers, Rusty Petals, Matchheads, Coachwood, Christmas Bush, Mangroves and Hopbush.

September 18th

Leader: Robert Failes
Topic: Western Mueller Track (bring lunch & water) return about 3pm
Background:

Whipbird Gulley

We take the opportunity to study the vegetation along the Mueller Track as it roughly follows Ku-ring-gai Creek in the western part of KWG. This track supports a surprising number of plants not found elsewhere in KWG. Please wear suitable footwear. Bring a hat, water and a packed lunch to eat near the top of Phantom Falls.
