Mrs Rawling owns the 2.1ha North Taieri Rd garden with her husband, Mike Rawling. She is also the convener of Heritage Roses Otago, which will be holding a workshop on February 27 at the garden.
Titled "Growing Roses Locally — Practical Hints", the workshop will run from 1pm-4pm.
Attendees will learn how best to grow and care for heritage roses, how to prune them, take cuttings, and make willow water, a hormone solution made from willow branches that stimulates root growth.
Heritage Roses Otago would like to spark interest in growing and caring for heritage roses and maybe gain a few new members, Mrs Rawling said.
The group would provide afternoon tea and potting mix to participants.
The New Zealand Gardens Trust listed Wylde Willow Garden as a Garden of National Significance in 2010. It is open to the public by appointment.
