Kentucky bluegrass is a popular choice for its emerald, blue-green colour. It does well in Canada's cooler climate, growing most vigorously in the spring and fall. KBG likes lots of sun but also performs in moderate shade and can stand up well to low-cut mowing. It's particularly sought after for its lush, dense and durable qualities, and especially its ability to self-spread via rhizomes that spread out laterally. This process creates a dense, thick stand of turf that can recover quickly from damage. Some patience is required when planting a Kentucky Bluegrass lawn as germination takes longer than other cool season grasses (7-14 days), but those who wait are rewarded with a dark, lush and durable lawn.
