• sternii
  • Several plants species have been named in his honour, such as Buddleja sterniana (now B. crispa), Cotoneaster sternianus, Helleborus ×sternii (= H. argutifolius × H. lividus) and Paeonia sterniana. (wikipedia.org)
  • Hybrids between H. niger and H. × sternii (itself a hybrid, between H. argutifolius and H. lividus) were originally called H. × nigristern, but this name has been changed in favour of H. × ericsmithii (commemorating the plantsman who made the cross in the 1960s and introduced it in 1972, through The Plantsmen nursery).

  • Characteristics
  • Raised in 2000 by plant breeder David Tristram (whose father gave the first 'Potter's Wheel' to Washfield Nursery), Helleborus 'Walberton's Rosemary' is pink-flowered, extremely floriferous, and seems to be intermediate between its parents in many other characteristics. (wikipedia.org)
