Thelymitra antennifera – Rabbit Ears
The genus of sun orchids can be quite daunting to identify, but thankfully in South Australia Thelymitra antennifera is the most commonly encountered yellow sun orchid with its distinctive column. It has two common names. Rabbit ears describe the dark red “ears” that sit on top of the column. The second name is Lemon Scented Sun orchid, which describes the soft scent emitted by these flowers.
This sun orchid has thin grass like leaf with a dark purple base. The plants quite commonly have several flowers on them. The flowers are relatively large compared to the small, short stem that holds them.
The Rabbit Ears sun orchid can be found right across Australia from Western Australia into Victoria and Tasmania. It tends to enjoy a slightly opened woodland, and can be often found on the top of ridges and further down in the valleys. It is common, and has a long flowering range. Depending on the region, it can be seen in flower from August to November on any warm day.
