Tetraneuris acaulis, also Hymenoxys
Native perennial four-nerve daisy does great in full sun or afternoon shade, with very little water or maintenance.
They prefer rocky, well-drained soil, so if you have heavy clay, you may find them a challenge. If that’s the case in your garden, consider building berms or raised beds with sandy soil and some added organic matter, but not too much. Or even containers, where again, you can control the soil and drainage, will work with this beautiful perennial.
The bright yellow, cheerful flowers will greet you from spring all the way through the heat of summer.
And you’ll need several plants for grouping, since four-nerve daisy stays a petite 6” by 6” in size. Water sparingly and don’t mulch heavily, as these plants easily rot if they stay too wet.
