Extension publications like Mississippi State University and Georgia Extension emphasize selecting a manageable diversity of species suited to your site conditions—rather than overwhelming yourself with dozens of options—that ensures long-term garden success. As the University of Georgia notes, “you don’t have to plant 50 species … a stunning display with five species or varieties …” is entirely possible.
Choosing around 19 selections strikes a sweet spot: it offers enough botanical variety for interest, bloom timing, and pollinator appeal without introducing maintenance overload.
