Judges from nearly 100 countries, including Australia and America, are in Glasgow for this year's International Rose Trials.
Worldwide experts are in Tollcross Park for the 25th annual event held each year over two days.
Tollcross's world- famous rose gardens have trialled 600 varieties of new rose since the first plantings in 1986.
The garden has 16 dedicated beds with nearly 4100 plants.
Awards to be handed out this weekend include The Golden Prize of the City of Glasgow and The Tollcross Fragrance Prize.
There will also be the Best Established Rose and The People's Choice award.
Certificates of merit and commendation will also be handed out for the roses, which will be seen by thousands of visitors.
The Trials cover nearly one hectare of land in the park, which faces on to Tollcross Road and is open to flower fans and members of the public.
In 2009 Tollcross Park became one of only 35 gardens worldwide to win the the Award of Garden Excellence by The World Federation of Rose Societies
