Dark green, twisted, and spiraled foliage, makes a good filler in a container. Water plant as well. Juncus is perfect for streamside and other constantly moist or wet sites having rich, acidic soil. It will grow in shallow water no deeper than 3 inches. Though it prefers partial shade, Juncus will also grow in full sun if given adequate moisture.

Heat tolerant and deadheading is not necessary.

I got seeds of this in last Nov.'s NFSR from ishareflowers. I didn't get around to sowing them until July. They sprouted in a couple of weeks and grew slowly, but I ended up with 4 plants. Now, 4 months later, the largest is 2" tall and wide and is starting to "twist." I read in the database that they like moist soil. They are in potting soil with average drainage, but I never let them dry out and they are happy with slightly damp feet.

They've been in 2" mouth wash cups about 6 months & needed a bigger pot since most have 6" to 7" spirals.
tabbycat On October 23, 2018 Transplanted
1 is larger than lots of tiny ones so I transplanted it into own pot Oct. 23. Others divided Dec. 21 to 12 more clusters in two 6 pks. to get bigger. Meredith got the large one on her Jan. birthday.
