Juncus spp.

Juncus Plant Features

Juncus is an unusual houseplant, annual, or perennial that has wonderful, gray-green textural leaves. Some varieties have extra interest because their leaves twist and curl as they grows, making them look like living sculptures. While these exotic plants look hard to grow, they're actually easy indoors and out! 

Indoors, use juncus to add flair to your desk at work or school, or as a dramatic accent in your kitchen, living room, or den. Its gray-green leaves are a lovely neutral color, making it work with just about any interior color scheme -- and any type of pot (especially the warm, earthy tones of the classic clay container).

Outdoors, juncus is perfect for garden beds and borders, as well as adding fantastic texture to container gardens.

Juncus Growing Instructions

Indoors, grow juncus as an exotic houseplant in medium to bright light for the best effect. It can take direct sun on the foliage, even in Southern climates. Water the plant liberally as it likes moist soil. In fact, it's tough to overwater this unusual houseplant! Juncus appreciates fertilizer once or twice a year. You can use any houseplant fertilizer, following the directions on the product packaging. 

Outdoors, grow juncus in sun or shade. It does best in evenly moist or even wet soil. While it doesn't require fertilizer outdoors, you can fertilize juncus with any general-purpose fertilizer. Follow the directions on the product packaging. Pruning typically isn't necessary. 

Note: Juncus is not meant for human or animal consumption.
