Dunedin Botanic Garden plant collections curator Stephen Bishop (left) and apprentice gardener Andy Anderson tend a 3-D display yesterday to mark the 150th anniversary of New Zealand's oldest public gardens next year.
The raised 6m by 3.5m display features a variety of succulents, which spell out "DBG 150", Mr Bishop said.
"It's been designed as a foliage display, rather than a flower display."
The bed was planted on Monday, with the help of Otago Polytechnic landscaping students, and the lettering is expected to be flowering by Christmas.
It will remain on display by the garden's duckpond until April. A calendar listing 150th anniversary events at the gardens would be released on January 13, information services officer Clare Fraser said.
