This tough and reliable colourful plant is a curse in more temperate gardens but living by my philosophy of, ‘if it grows in Zone three , it is welcome’, I love this long blooming perennial in June. It helps fill the gap before the roses and delphiniums. There are those that will tell you it is invasive and it can be, if you don’t divide it and simply pull and remove some each year. It is not as though it pops up all over the place. The seeds don’t seem to do the spreading – it is the rhizomatous roots! Yellow Loosestrife will grow in part shade to full shade which is another bonus. It grows in full sun in my garden. The pink Loosestrife which grows near streams and damp places has been listed as invasive in most parts of Canada but I hope this one does not get labelled as such.
