545718_4081144861436_2126115043_nI am an honours student researching the drought tolerance of nifty Australian geophytes and their potential use on green roofs.

Geophytes are species of plants that can go dormant to underground storage organs when conditions are unfavourable. Common examples include daffodils, tulips and other bulbs, and tuberous plants like potato and carrot.  The species that I’m studying are all native to Australia and include Microseris lanceolata (Yam daisy), Bulbine bulbosa (Bulbine lily) and Arthropodium milleflorum (Pale vanilla lily).

DSC_9983-1My current research will determine how well these species survive and recover from drought periods of 30-60 days, and how their morphological characteristics and water use strategies change.  This will increase the understanding of how differing drought tolerance abilities relate to plant traits, and hopefully identify species that are ideal for green roofs.

In the future I hope to pursue a Phd into the wonderful, if somewhat neglected, world of Australian geophytes.
