HTA member Noel Allan, Galloway Heathers, is providing MSP’s with handmade heather buttonholes for the event, and these will be presented to Christine Grahame MSP on the morning of 27 May.
Members of the Scottish Parliament are being asked to wear the buttonholes to help promote the event, and also demonstrate their support for Scottish horticulture.
Speakers include environment minister Aileen McLeod, Trellis patron Dr Richard Simpson and event sponsor Christine Grahame.
The reception will take place on the 27 May 2015 in the Garden Lobby of the Scottish Parliament.
A number of charities, organisations and friends of the HTA will also have stands at the event – allowing MSPs to find out more about the diverse nature of the gardening and horticulture sector.
HTA chief executive Carol Paris said: "This event provides us with the opportunity to demonstrate the importance of horticulture in Scotland and the role it plays across many aspects of our lives to a parliamentary audience.
"The HTA has an increasing presence in Scotland, with the recruitment of Neil Cummings as Regional Business Manager for Scotland, Northern Ireland and Ireland last year, as well as involvement in Gardening Scotland and increasing public affairs activity to ensure that members’ issues are heard."
HTA President Stan Green added: "Scotland has an amazing horticultural heritage – from internationally renowned parks, public and private gardens with many societies and community groups to boot. We are all waking up to the importance of horticulture in our daily lives in Scotland, individually substantial, but collectively hugely significant. What better place to come, than the Scottish Parliament to collectively celebrate the importance of plants in our lives, and most importantly how we can build on this privileged inheritance going forward."
