Wonderfully quirky! So many garden centers carry the same plant material but at Alwerdt’s (technically in Altamont, IL), you get the sense you’re viewing the owners’ personal interests! It’s laid out as if they thought, “Let’s add a greenhouse here! How about more display gardens there?” It’s not exactly logical but it’s so fun to explore. This is off Interstate 70 on your way from anywhere east of St. Louis to the Missouri Botanical Garden because of COURSE that’s where you’re headed! Alwerdt’s has knowledgeable staff members, a wide variety of plants, good prices and an adjoining sculpture garden.
