Fleur du jour.

Loosestrife, Lysimachia punctata.

This is loosestrife, a perennial native to Eurasia. There is a small patch of this plant, a relict of one of the old gardens at Terra Nova, growing near the base of the elephantine beech. Without looking, I almost parked my bike on it. This species can be invasive, especially if planted at the edge of a pond or other damp place, but is not as disasterously invasive as its partial namesake, purple loosestrife,

Purple loosestrife, Lythrum salicaria.

which also occurs at Terra Nova and is spreading out beyond the dyke. The plague in this picture was eventually eradicated by building a subdivision on top of it. That'll teach it.

The field of purple loosestrife looks "defastatingly" beautiful!

On the up-side... recent research has shown that Purple Loosestrife isn't the evil invader it was initially made out to be, instead actually increasing local biodiversity in an area, rather than decreasing it (it was a pet peeve of a prof of mine who did a fair bit of research on the plant's effects that folks jumped to negative conclusions without data to back it up). I've never seen a wetland where it's completely (or even mostly) taken over, like it was accused of doing, and I think it adds some nice colour.

Exactly! The only invasive species I really worry about is Homo economicus (growth-is-good humans). I love your blog.
