Wildflowers of spring (4)

Heart-leaved Arnica ~ Arnica cordifolia 5/16

Pretty, but I have been unable to identify it 5/16

Field Chickweed ~ Cerastium arvense 5/16

Leafy Spurge ~ Euphorbia esula 5/17

This is a Eurasian introduction that has become a serious threat to rangeland. It is difficult to eradicate and is poisonous.

Star Solomon’s Seal ~ Maianthemum stellatum 5/17

Oregon Grape ~ Mahonia aquifolium 5/17

I couldn’t resist posting another photo of this. I liked the setting among the other plants in a typical setting and these are blossoming just everywhere right now.
