Purple Pitcher Plant Size and Humidity Dome Removal: Acclimate Slowly

S. purpurea grows **up to 1 ft wide, 6 inches tall**. Plants sold in humidity domes need **gradual hardening off** – domes are a "bad idea" that weakens plants.

Dome Removal Protocol

• Open dome **⅛ inch every 3 days** (or punch 6 holes every 3 days).
• After ~2 weeks, remove dome entirely.
• If plant was open-air before, still acclimate gradually.

Unique Water Note

S. purpurea **lacks pitcher lids** – it relies on rain to fill pitchers. **Add water to pitchers** to enable insect capture and nitrogen gain. This is the **only** carnivorous plant where manual pitcher filling is recommended.

Avoid sellers who use domes and give "high humidity" instructions.
