Angel ...

The yellow archangel to be exact. Weed would you say. But do not be too quick. Wiki says:

Lamium galeobdolon, commonly known as yellow archangel, is a widespread wildflower in Europe, and has been introduced elsewhere as a garden plant.

In our backyard it's a garden plant. You have to be careful, because it can be invasive in places where it is not native and caution must be taken when planting in these areas (Wiki again).

I pictured the plant on the first day of its bloom ... ;)
