The seminar will be led by the University of Sheffield's department of landscape professor James Hitchmough, who has been developing techniques to reliably create meadows and prairies through sowing seed in private and public parks and gardens.
It will build on the experiences of Hitchmough, who planted the steppe-prairie garden at RHS Wisley in January last year.
That success is being replicated elsewhere, with plans for 4ha of native wildflower meadows for the London 2012 Olympics.
The day will be introduced by Tom Stuart-Smith, who has worked in partnership with Hitchmough.
The morning will focus on principles and practices while the afternoon will look at case studies of successful examples, including that at Wisley.
Keith Wiley will present a study on his integration of sowing and planting at the Garden House, Buckland Monachorum. Chris Jones will discuss his work in sowing annual and perennial meadows in low-input urban green space in Telford New Town.
