Ray and Clinton Nesci are prominent figures in Australia's bonsai community, renowned for their expertise and dedication to the art.

Since its inception, the nursery has been a cornerstone for bonsai enthusiasts, offering a diverse selection of plant material, pots, and accessories.

Clinton, Ray's son, serves as the Director of the nursery. He attended The Hills Grammar School and furthered his horticultural education at the Ryde School of Horticulture, obtaining a Nursery Trade Certificate.

  Acer buergerianum 'Nescii'
  Acer buergerianum 'Nesci’s Gold'
  Malus Nesci
  Silver Edge Chinese Elm 'Mini Gold'

  Improved cultivars of the Hokkaido Elm and Kingsville Box

Their nursery is celebrated for its extensive range of bonsai, from affordable starter plants to advanced specimens. Customers frequently commend the nursery's friendly atmosphere and the Nesci family's willingness to share their extensive knowledge.

Beyond their nursery operations, both Ray and Clinton actively contribute to the bonsai community by offering services such as free advice, mobile bonsai care, repotting, wiring, pruning, and fertilizing.

Their combined efforts have significantly influenced the appreciation and practice of bonsai in Australia.
