Just had a garden maintenance day, and noted that the Lupines in the first garden are having twofold troubles- first off, they’re growing too high, and now they have aphids galore. When we started researching for this project, we had a number of different criteria for selecting plants; one of them was making sure the plants fit under the City three-feet height limit for planting strips. This was harder than it sounds- finding native plant shrubs that fall under three feet turned out to be a challenge. We were able to find a couple, and for the rest, we use some non-native shrubs now too. Anyway, this is all to say, that when we selected this Lupine, our research said that they would only grow to three feet, and now they’ve reached four feet! So, sadly, we’ll have to remove these. From what I understand, these are River Lupine, and the lower growing Arctic Lupine (also a native) will be a much better choice.
Luckily, the aphids seem to only like the Lupine, and nothing else, so far.
