A couple years ago I was walking over to a friend’s house when I was arrested by the fragrance coming from a lovely compact shrub along the sidewalk. It took me a while to discover that it was Daphne laureola (Spurge Laurel)–which didn’t surprise me, because my experience with Daphne so far is that they are delightfully fragrant! I have a Daphne odora ‘Marginata’, and my neighbour has (I think) Daphne x tansatlantica ‘Summer Ice’.
The unfortunate thing about all Daphnes is that all parts of them are toxic to humans when ingested, and sap can cause reactions on the skin. Now, that’s bad enough with the hybrid versions of Daphne, but with Daphne laureola, a species native to Europe, it carries more problems. First of all (unlike the hybrids) it’s tolerant of almost all soils–although it’s native soil is alkaline, it’s doing just fine in our acidic local soil, and especially in wooded areas of the Douglas-fir and Garry Oak ecosystems. (See this article on the Vancouver Master Gardener website.) It also (unlike the hybrids) produces berries, toxic to humans and small animals, but not to birds. So the birds eat the berries and deposit the seeds wherever they fly, spreading Daphne laureola far beyond where it was planted.
It is undeniably a pretty shrub, but it has too many disadvantages to justify planting it in your garden. Alternatives that meet the same cultural needs include Skimmia, Sarcococca, Pieris, small Rhododendrons and Azaleas (although the last two aren’t fragrant), and even the beautiful Daphne odora and Daphne x transatlantica.
Would you consider removing your Daphne laureloa?
