There is a large evergreen shrub/tree growing in Langford, near Victoria BC, which puts on growth spurts of several inches per year. I am wondering what it is. I don't believe the flowers have any scent, but I have emailed about this and will update this thread with the information, once I receive an answer.
Thank you Axel for your quick response. It does seem this shrub is a Prunus lusitanica, I will pass on the information.
You can use it to host Western Tiger Swallowtail, Papilio rutulus. Plant something to attract the adult to let them know it is there!
Seeds into parks and other wooded sites near habitations in this region to join in the mix of Old World woody weeds such as common hawthorn, ivy, English laurel, spurge laurel and holly that is infesting such places these days.
