VernoniaeHeteromorphicAthyrium filix-feminaWas found by Miss Vernon probably in the 1850s or early 1860s and was named by Mr. Swynfen Jervis of Darlaston Hall. Although Reginald Kaye claims to have had the original Vernoniae clone, it has almost certainly has been lost but fortunately this cultivar comes largely true from spore. It is a quite distinctive cultivar, the pinnae being triangular shaped and crisp.Generally as for species. Will grow in most soils but prefers acid conditions; as someone says in good 'woodland duff'. Also best in light shade but will tolerate some sun in the morning and evening, or more if in damp conditions. Protect from strong winds which would damage the fronds.Ian Unsworth
