For years these plants have been on our lists of must-haves—but they have tragically never made it into the garden. Why? Truthfully it’s probably because both Steve and Danielle suffer from short term memory loss and when it comes to buying plants, they are easily distracted. But then something happens, like a visit to a botanic garden, that triggers them to say, “Why am I not growing this?” These are amazing plants that really standout in their season of glory, but sadly, they seem to always get left of the shopping list. Apparently plant guru Andy Pulte can relate because he chimes in with some plants that he’s kicking himself for not planting. Is this a universal thing with gardeners? We think so.   Expert testimony: Andy Pulte is a faculty member in the Plant Sciences department at the University of Tennessee, Knoxville.
