The very groovy & very rare Caladenia amnicola (Streamside Spider #Orchid) starting to #flower near Armidale. Known only from the type locality, we hope to get some seeds into #PlantBank for #conservation storage & research for the first time soon. #SavingOurSpecies #biodiversity

Some spectacular and very encouraging #bushfirerecovery in the foothills of Mount Imlay NSW south coast. I’ve never seen so many Callistemon citrinus in flower at one spot! #ozplants #plantbank #myrtaceae

Maybe it's rare & #endangered Callistemon forresterae, maybe it's not, but whatever it is, it's mighty pretty. Hunting rare species isn't always easy (especially when they're tricky to ID), but who can complain when the target is so stunning! #PlantBank #conservation #ozplants

Seeing wild Sarcochilus fitzgeraldii (Ravine #Orchid) is always a thrill given its rarity due to poaching these days. The brilliant #flowers certainly are attractive, but it's important we preserve these populations for the future too #conservation #SavingOurSpecies #biodiversity

Darwinia #flowers are some of my favourites with their intricate shapes. This is the Blue Mountains endemic D. taxifolia subsp. taxifolia, a real beauty of a plant when you get up close and personal like this. #PlantBank #conservation #ozplants #NaturePhotography #botany

What do I do in my spare time? Play with plants of course! Tonight, it’s Extracting Wollemi Pine seeds. There’s approximately 300 seeds in this cone but only 23 are viable #conservation #BlueMountainsBG #BGANZ #wollemipine @BlueMountainsBG @SiemonJohn @bgcpsydney @RBGSydney

I’ve been breeding pitcher plants for almost 15 years and finally, I’ve made a useful one. This hybrid just loves eating introduced European Wasps! #plantbreeding #plantswithbite #pitcherplant #Nepenthes

Despite suffering the stresses of drought and fire, @BlueMountainsBG Wollemi Pines have produced valuable seed. The Garden is home to a critical conservation collection with more diversity than is found in the wild. Can you tell which 3 seeds are viable? #conservation
