helianthemum, song, long grass

I have been referring to this as a cistus, but my flower bookcalls it helianthemum. It is however a member of the family, Cistaceae. So I suppose we are both right. I bought it as a small plant in the Farmers' Market several years ago. Now it is a shrub about five feet high, about to be covered in these white flowers with slender yellow stamens. Here is one of its first blooms this year.

Blackbirds have been awake early these last few weeks. Their song seems to me, as I lie drowsily in bed like water flowing fast, cool and clear over the pebbled bottom of a stream.

What are these: Jersey Pop Up, Oregon 5, Hartford 4, Montana 6, Minnesota? All have the qualifcation Outwell. They are tents, advertised outside a camping equipment shop.
