Morphology

ironweed = iron + weed (semi-transparent) = iron + weed

The parts 'iron' and 'weed' are recognizable, but the compound refers to a specific plant species and the precise motivation for 'iron' (e.g. toughness or color) is metaphorical and not directly inferable by all learners.

Etymology

Ironweed is made of iron ('a strong metal') and weed ('a wild plant'), so picture a wild plant that is very tough like iron or that turns a rusty, iron-like color. That's why the name fits the tall plant with purple flowers that often turn a rusty color.
