Right about now you might be asking yourself, "What exactly is a workhorse plant?" In our minds it is a plant that asks little from us but delivers a whole lot to the garden. These are tough plants, capable of fitting into an array of spots and producing multiple seasons of interest. They aren't the stars (aka focal points), and they aren't the supporting cast (aka reliable performers). They are more like stage managers, ensuring that the garden always looks decent. We thought it was high time that these unsung garden heroes got some praise, since rarely are awards given to plants that are simply defined as "solid." Saddle up for a long list of perennials—and a few shrubs—you'll be happy to have ride into your garden.

Do you ever find yourself recommending the same handful of plants to friends and neighbors? We do. These might not being the splashiest of plants, or even the ones that you'd base an entire design around. But, these are fantastic herbaceous perennials—the meat and potatoes of the garden. To make things even more interesting, we limited ourselves down to choosing just four of these go-to plants. Our choices have multiple seasons of interest, thrive under less-than-ideal conditions, and in our minds, are essential in any great garden.

For those who are a little confused by this episode’s theme let us try to explain. Yes, all garden beds are built with plants. But, there are certain plants that are such solid performers that they are the perfect jumping off point for building a bed. These are not the dramatic focal points that catch everyone’s attention, nor are they the stoic bones of the garden that just play a background role. These are the perfectly chicken tenders, around which the rest of the meal comes together. Steve would’ve preferred a baked goods analogy here, but you don’t always get what you want. Looking to start a new garden and need ideas of where to start? Or, need more solid performers to round out a bed that is lacking something, but you don’t know what? These plants could help.

Spring has long ago sprung and now that all the pruning, dividing, and mulching is done we’re ready to plant up our containers. Like many of you, we are tempted to try something new every year and sometimes end up with a plant that is worthwhile. But we always make sure to incorporate a few tried-and–true container plants. These are selections that never let us down, and if you were to show up on our doorstep tomorrow, you’d likely see them filling in our pots (just call ahead, we want to be sure to pick up a little bit before your arrival). We’ve got fillers, thrillers, and even some spillers on the list, so be sure to listen for some sure-fire options.

Alternate titles for this episode: Plants That Stink or Smell This Episode. Kidding aside, lovely smelling plants are a bonus that every garden deserves. We all spend so much time on making sure our gardens look good, we seldom think about how they smell. And we’re not just talking roses here people. On today’s episode we feature a plethora of perennials and even a couple of shrubs that make us think of root beer, vanilla, and all sorts of sugary confections. Steve got hungry halfway through, so please forgive the few minutes of dead air while he tracked down the nearest donut.

It’s easy to get excited about the first tulip or even the first dandelion in the yard (OK—that might be a stretch). But what about those plants that don’t get all the love and attention, yet still brighten up those first few months of the gardening season? Today we’re honoring those unsung heroes of the spring garden—plants that need a better PR agent because they’re marvelous, but not very well-known. We’ve got a few native dark horses and even a shrub that Steve thought he’d never like. To get you really laughing we revisit some childhood memories of using spring plants in mischievous ways. Finally, we debut a new segment where we give a brief look into what’s going on (good, bad, and ugly) in our gardens right now.

Finding interesting plants for shade can be a struggle but when you add in the desire for that plant to be a woody shrub, the list narrows even more. But these structural wonders are essential in giving our shady beds and borders depth and real presence. In this episode we feature shrubs that will tolerant a range of low-light situations. Some flower beautifully in spring or winter, other save their best show for fall. Regardless, the list is robust, especially because associate editor Carol Collins joins us to highlight an impressive native plant she adores and a peony (yes, that’s right a woody tree peony counts as a shrub) that everyone will want to save their pennies to purchase.

Expert testimony: Andrew Bunting Vice President of Public Horticulture at the Pennsylvania Horticulture Society.

Despite there still being snow on the ground here in the Northeast, we’re thinking spring. Yes there are daffodils and tulips to look forward to, but perhaps even more impressive is the show of spring flowering trees. It’s an incredible sight to see a woody plant that was nothing but bare brown branches a few weeks earlier, explode into a flurry of pastel blooms. Our selections today are impressive, and most are moderately sized so they are easy to include in the smallest of properties. Are you suffering from the winter doldrums still? Then give this episode a listen and you’ll soon be dreaming of more colorful days to come.
