One of my favorite ways to establish cohesiveness in the garden is with groundcovers. There are many to choose from that adapt to a variety of different conditions. One that I use often because it spreads, but is easy to maintain is known by its common name Blue Star Creeper or botanical name, Isotoma fluviatilis. It is considered an evergreen and it can be found at most nurseries.
A little goes along way, from a flat or two I have transplanted dozens of clumps throughout the landscape. It performs well in sun to part sun and once established it is relatively drought tolerant. Blue Star Creeper handles foot traffic well and creates a tightknit mat of small star shaped bluish-purple flowers from May thru September. In the Northwest, the month of June’s floral display is quite fantastic.
One use for Blue Star Creeper that looks especially graceful is planting it between flagstone on a patio or walkway. It fills in nicely and looks quite spectacular when it blooms. It also makes a great border to the edge of a perennial garden. The white to slightly blue or purple flowers vividly define the border of a garden and give definition to the perennials in the background.
One drawback of using Blue Star Creeper or any ground cover for that matter is, if weeds find their way in it can become a maintenance issue. But from one gardener to another we know this to be true for just about anything that goes in the garden. I wouldn’t let this hold me back from using Blue Star Creeper in my plantings and you shouldn’t either.
