Which plant has bright yellow flowers with no orange throat and waxy leaves?

• A. Yellow Toadflax
• B. Dalmatian Toadflax
• C. Quackgrass
• D. Hoary Cress

Answer: (B)

Choosing the plant with bright yellow flowers and waxy leaves hinges on two features: flower throat color and leaf texture. Dalmatian toadflax has pale yellow flowers and lacks an orange throat, and its leaves are waxy and bluish-green, giving the plant a glaucous look. Yellow toadflax would typically show a noticeable orange throat, so it doesn't match as well. The other two options aren’t a match for bright yellow flowers: one is a grass with non-yellow blooms, and the other has white flowers. So the combination of pale yellow flowers with no orange throat and waxy leaves best fits Dalmatian toadflax.
