Aptly named, this tiny ground cover offers up the sweet aroma of vanilla or mowed hay when the foliage is crushed. I tried to grow this shade loving herbal in Virginia but it suffered in the summer heat… never died but never thrived. Now in zone 5b-6, my sweet woodruff (Galium odoratum) is a well-behaved and dense ground cover in a shade garden. I am thrilled.
It spreads by stolons and rooting in place and some insist it will take over a perennial bed. If it does, that’s fine. I have it planted beneath the shade of a crabapple and among woody shrubs. It it wants to venture beyond, I will face that when the time comes. It is shallow rooted so I don’t think it’ll ever be a weedy thug like English ivy or vinca minor or mint or bungleweed or dead nettle… that I have waged wars against in other garden settings.
The delicate flower buds are ready to unfurl their white petals on each of the whorled leaves above. It can grow taller, but mine grows only 6″ tall on slender stems. It may go dormant in a drought like we had last summer, but is happy and flourishing in the cool, wet weather we’re enjoying in this 2017 spring.
Although I haven’t done it, folks harvest and dry the leaves for potpourri… or it’s used for perfumes and a bit of German wine-based punch. Not for me. This sweet woodruff will serve its purpose solely as a beautiful spring blooming ground cover. How divine!
