Staff from Plantscape have been driving to Glasgow over the past two weeks to install 600 barrier baskets and 1,200 basket liners.
The rest of the order comprises 30 wooden planters, 30 round tree planters and 18 Eyefull towers, which comprise of three tiers of planters arranged one on top of another like a wedding cake.
They will be placed around the SECC precinct, which is hosting sports including the boxing, gymnastics and netball, and the Emirates Arena, the venue for the badminton.
Plantscape managing director Mark Stone said Glasgow made an even bigger order in 2007, when it decorated the streets to impress judges who were visiting to decide where to award the Games.
It also follows Plantscape’s involvement in the 2012 Olympic Games, when it supplied hundreds of planters for the streets of Broxbourne in Hertfordshire, which hosted the white-water kayak and canoeing events.
Managing director Mark Stone said: "We are extremely proud to be decorating Glasgow for the Commonwealth Games. The city will be rolling out the red carpet to thousands of athletes, officials and visitors over the next few weeks and it is wonderful to think that our displays will ensure that the city will be looking its very best.
"What makes it even more rewarding is that we provided a display seven years ago to welcome the Commonwealth Games judging panel. Obviously, that display helped the city win the Games, so we are delighted to be working for the Games themselves.
"Planting up and transporting so many planters requires a huge logistical effort at a time of the year when we are usually winding down. However, we are working around the clock to get everything in place and we can’t wait until Glasgow gets to enjoy our displays."
Meanwhile, Kernock Park Plants has supplied eight carpet beds for three Glasgow Parks, plus an InstaPlant mascot made by David Ogilvie Engineering.
