Asteraceae (Composite or Sunflower Family)
There is such a multitude of composites that I have barely begun, and may never finish. One has to observe them throughout an entire life cycle, making note of everything from roots to seeds. I guess I'm lazy. Sigh.
Most of these species are flowers, but Sage (Seriphidium) and Rabbitbrush (Chrysothamnus) are shrubs. Our only North American aster is Aster alpinus, or Alpine Aster, only found in the high mountains in this hemisphere; otherwise, all our local asters are reclassified as Symphyotrichums. Asters elsewhere have other names. Cultivars may still be called "Asters." As of January 2018, APG IV places Family Asteraceae in the Order Asterales.
