Do you know the difference between pampas and native toe toe?
Common and purple pampas should not be confused with the four native Cortaderiaspecies (commonly referred to as toetoe)
Toetoe is generally smaller, (no more than three metres tall when flowering) and the flowers, which are a creamy-yellow, ‘droop’ significantly from October to January.
Toetoe also has a white waxy surface on the leaf base where the common and purple pampas have ‘hairy’ leaves.
Toetoe leaves have distinct veins between the mid-rib and leaf edge. Pampas leaves have a conspicuous mid-rib but lack distinct veins between the mid-rib and leaf edge.
