Given that this species grows low to the ground, it can tolerate both full sun to part shade. We sometimes grow ours packed between taller plants and they love it! Even in part shade, these plants can grow really big, but they won't be as colorful compared to plants grown in full sun.
Outdoors here in Northern California, Parrot pitcher plants (S. psittacina) put on their best show in late fall: sometimes, they won't produce their biggest traps until almost late October. For best results, these plants need warm days (75F+) during the fall. Cooler nights into the 50s and even high 40s during this time won't affect pitcher growth negatively.
These medium-large sized divisions offered are extremely healthy and have great growth momentum! Many are starting to form several growth points, which will give you a head start to producing that large, specimen-sized clump!
