Uncinia rubra 'Everflame' is native to New Zealand. It is a genus from the Cyperaceae family and commonly named red hook sedge.
The red hook sedge is an evergreen. That gives you something nice and colorful to look at in the winter. Although Uncinia rubra 'Everflame' looks like an ornamental grass it is not a grass. It belongs to a different family.
The Uncinia rubra 'Everflame' prefers a moist, well-drained and sheltered spot and sunny or with part shade. I had placed the Uncinia rubra 'Everflame' in a sunny but dry spot and it did not grow very well there. So a choose a position with a little less sun and more moist for this ornamental grass and now it grows perfectly.
In the summer the red hook sedge makes flower-spikes but not very many and they do not have any ornamental value. The clumps spread slowly.
I do not cover the Uncinia rubra 'Everflame' in the winter and it has survived temperatures of 5 ºF (-15 ºC). If you have positioned your red hook sedge in a spot that is not very sheltered then it is wise to cover this ornamental grass in the winter because it is not very hardy.
