For some reason, I find myself attracted to Nepenthes with big wings on the front of the pitchers like N. rafflesiana such as seen here:
It's even better if they're also spiky! More spikes can (for me) make up for being smaller as they still have a good visual impact.
N. 'viking' (mirabilis var globosa) also seems to have fairly prominant wings.
What are some other species with big wings? Which ones are considered fairly easy growers?
