|Hundreds of tiny pink buds on this Daphne 'Carol Mackie' will open gradually over a 3 to 4 week period, depending on weather, filling my back garden with fragrance.|
My daphne (formally known as Daphne x burkwoodii 'Carol Mackie') is not as common in Seattle gardens as Daphne odora, or winter daphne. Winter daphne blooms earlier in the year, usually in February. You will find several wonderful specimens in the Witt Winter Garden at the Washington Park Arboretum.
Although daphnes are popular shrubs in the Northwest, they have a reputation for being fussy. They can be planted with all the loving care and attention you can muster, and yet fail to grow. They don't like soil that is too wet, but they don't like to dry out, either. They seem to be doing well, then suddenly, without warning, die.
There is a trick, however, that you can use to increase the odds of your daphne's survival. I've been using this trick with great success for almost 20 years. It is simply this, plant your daphne near a concrete walkway or (better) throw a couple of pieces of concrete rubble into the planting hole. That's what I did with the happy plant you see above.
Why does this work? The soils in the Northwest are acidic, perfect for acid lovers like rhododendrons, azaleas and blueberries. But plants like daphne, that prefer more alkaline soil, struggle. The lime contained in the concrete leaches into the soil a little bit each time it rains or when you water. That lime sweetens the soil around your daphne slightly, making for a happier plant. And when Daphne is happy, she brings beauty to your garden.
