From a plant guy, a title like that probably sounds a bit like blasphemy. Don’t get me wrong, I love plants simply for the sake of trying something new and different, but our neighbors (and many of you) may not want to spend your money quite so casually.  
What we all looking for are solutions that plants will take care – not necessarily the plants themselves. Using perennials as an example, here are some solutions that need taking care of.
Many of the plants mentioned here and some of the solutions are available on the Armitage App

Balcony/small spaces: So many plants fit into this niche. Nearly every major annual program has balcony-ready combinations. And now we are seeing mixed plant container-ready offerings – or we can make our own. This is one area where perennials, annuals and shrubs should be wed. 

Birds: Not just hummingbirds (although that very mention brings dreamy smiles to many faces, but plants that attract wrens, bluebirds, chickadees, vireos and many others. Sunflowers, grasses, agastache, salvia, hibiscus … 

Butterflies: For the habitat gardener and landscaper, this package has been around for years. Discussions of Monarch habitat are only becoming more prevalent, but butterflies of all likes are desirable.  Eupatorium, Asclepias, Echinacea …

Deer, rabbit resistant: One of the most sought after solutions, regardless of locale. No longer any reason why such plants are not front and foremost on anyone’s discussion list.  Hellebores, herbs, salvias, amsonias …

Drought tolerant: Waterwise is a better marketing term – but these plants are becoming more and more in demand.  Herbs (lavender, thyme), grasses, sedums, coreopsis …

Foodscaping: Offering ornamentals that double as food items is becoming all the craze. Many cultivars of herbs and vegetables provide beauty and taste. 

Fragrance: Packaging a half dozen fragrant plants together like herbs (everyone loves lavender), agastache, phlox, violas …

Groundcover: No discussion needed here. Groundcovers and low maintenance are synonymous to most gardeners. There are many programs around the garden centers (Treadwell, Stepables …), lots of choices.
