I looked back through the last few years of photos hoping to find something worthwhile to show you and despite the dearth of single plant photos, I found two of plant combo's - one of which I will share with you today.
This combination is of Canadian Ginger Asarum canadense and blue -eyed grass Sisyrinchium angustifolium ‘Lucerne’ (say that three times quickly!). The ginger makes a great shade or woodland ground cover, and that's speaking from experience. It slowly spreads its way outwards but would never be considered aggressive, just friendly. It has soft leaves and puts out a weird and wonderful purple flower under the leaves in spring.
Blue eyed grass ‘Lucerne’ is a variety of blue-eyed grass that was discovered growing in a nursery near Lucerne, Switzerland. The plants form a low clump of grassy green leaves, bearing bright blue star-shaped flowers in May and June for several weeks. Despite its name it is not really a grass, but belongs instead in the Iris family.
I also grow the native blue -eyed grass. You can see its petals are pointed whereas Lucerne's are round. In it's natural habitat you will find it growing across the prairies, park lands and in open meadows. I first planted this little gem in a regular garden bed but it definitely prefers my gravel driveway. So, sun yes, moisture not so much.
