Ulex and Vernonia are both what?
Ulex Ulex (commonly known as gorse, furze or whin) is a genus of flowering plants in the family Fabaceae. The genus comprises about 20 species of thorny evergreen shrubs in the subfamily Faboideae of the pea family Fabaceae.

Ulmus × hollandica 'Superba' The hybrid elm cultivar Ulmus × hollandica 'Superba', once commonly known in the UK as the Canterbury Elm, is one of a number of hybrids arising from the crossing of the Wych Elm "U. glabra" with a variety of Field Elm "U. minor". It was identified by Morren as "U. montana (: glabra)" var. "superba" in 1848, Morren having adopted the name 'Superba' from the Fulham nurseryman Osborn who supplied the trees. It was confirmed by Krüssmann in 1962 as a cultivar. Krüssman (1984) states that 'Superba' is synonymous with the former "U. praestans" .
