Morphology
The phrase is a straightforward adjective+noun combination: 'purple' specifies the color of the noun 'silkweed', so the meaning (a silkweed plant that is purple) is directly compositional. This adjective–noun pattern is cross-linguistically common and would be immediately understandable to a B1 learner who knows both constituent words.
Etymology
Purple silkweed gets its name from two simple images: the plant's seed pods have soft, silky hairs like silk, and its flowers are pink-purple. So the name tells you this is a plant with silk-like seeds and purple flowers that attract butterflies.
