Aciphylla genus (Spear grass). This is a genus of about 40 species of stiff-leafed perennials. They are evergreen, with spiky foliage and flowers which are produced more freely on the male plants. They have deep tapering roots that will produce clusters of deeply divided basal leaves with long narrow leaflets and vicious spines at their tips. The plant produces strong long-spiny flowering stems which develop in the summer; they carry masses of small yellow-green, yellow or cream flowers.
