Linaria genistifolia (Dalmation Toadflax)
This larger cousin of Yellow Toadflax has heart-shaped waxy leaves. It is a more robust, aggressive plant than Linaria vulgaris, and is also a perennial. The two species are capable of hybridizing.
I collected this one in Nederland. I suspect this individual was just too tall for its own good, and it just lay down, hence its droopy look. Don't blame me.
