Fun Facts
- 🌱 Inkberry is native to southeastern North America and is the northernmost native holly species in eastern North America, making it extremely cold-hardy for a holly.
- 🌱 Only female plants produce berries; male plants are needed nearby for pollination, though a single female can set some berries without cross-pollination.
- 🌱 The common name 'inkberry' comes from the dark black berries which were historically used to make ink, though the practice is now largely historical.
