"The awards evening was a triumphant end to a year that has seen outstanding alumni successes at major design shows," said principal Jenny Gibbs.
"There were many comments for our outstanding director of garden design Annie Guilfoyle, and the eye-catching and innovative work of the graduates."
Student of the year award went to Andrew Lord, who has already been spotted by Andy Sturgeon, who has offered him a job.
Former GP turned KLC garden design student Peter Reader meanwhile used the ceremony to show off an award-winning project that is to be built at next year’s RHS Hampton Court Flower Show.
He won this year’s RHS and Wyevale East Nurseries’ national student design and build award with a garden for a young arty couple, keen on nature and travelling. His garden has rills and four zones, Mediterranean, prairie, New English and shade plants.
Reader, who is being mentored by BALI member Brian Herbert, said: "The economy is frightening but I’m used to working to deliver and am confident. Winning this award is a good career start and Wyevale has taken me to quarries and saw mills."
Guilfoyle agreed: "The best time to start a business is in recession: you can go to college while the economy is low and hit the ground running. There is money out there, not always for elite work but for borders and paving."
