Tim helped Janet run the award-winning Hollyoak Orchids near Pershore, Worcestershire.
"Tim was a perfectionist," she said last week. "He was absolutely committed to growing - it was his whole life."
Tim and Janet met at Pershore College where they studied horticulture. They ran Crabtree nursery and garden centre outside Bidford-on-Avon, Warwickshire, before deciding to specialise in a single crop.
"We could see orchids increasing in popularity and wanted somewhere where we could build glasshouses specifically for orchids," Janet said.
They moved to the Hollyoak nursery in 2003. In 2008 Hollyoak Orchids was awarded Grower of the Year in the pot plant and bedding category.
Oldest son Tom has returned to the nursery to help Janet run the business. Customers include Waitrose, Garden Centre Group and New Covent Garden.
Tim, a keen motorcyclist, was killed on a run to Wales on 2 October. He leaves Janet and their four children.
