The Mid Sussex Orchid Society is set to make a return visit to Paradise Park in Newhaven on Sunday February 23 from 11am to 4pm.
Dr Gary and Maria Firth and society members will give visitors expert tips on after-care.
There will be a display of orchids and tombola at the tourist attraction in Avis Road.
Plant manager at Paradise Park Mark Curtis said: “Most people will be familiar with Phalaenopsis, or moth orchid - a beautiful and easy to grow houseplant, which is also excellent value, as it holds its flowers over a long period. A more unusual species are the Gongora orchids, and these are collected by Gary and Maria as part of the National Plant Collection.”
Orchids are a popular houseplant but are found growing wild all over the world.
