type of plant, proper name
荀 refers to a type of plant, and it is also used as a proper name. The two senses are separate: one botanical, one nominal.
荀 combines 艹 (grass/plant) with 旬, which likely contributes the sound. The plant meaning fits the grass component, while the proper name usage is a separate application.
The grass top 艹 suggests a plant, and the bottom 旬 looks like a wrapped bundle. Picture a bundle of a specific plant: that's 荀.
For ジュン, imagine a plant named June-grass blooming in June: June -> ジュン, and the grass top 艹 reminds you it's a plant.
