Barbara Pierson knows nursery garden plants. As nursery manager at White Flower Farm in Litchfield, Connecticut, she is surrounded by all things growing, all day long, and she helps people from across the United States select plants for their landscapes. She gets all kinds of questions about every kind of nursery garden plants. Here's what she's learned about shopping for nursery plants to give your landscape a healthy, beautiful start.
Her No. 1 shopping secret that she shares with people looking around is to read the plant labels carefully: exposure, hardiness zone, mature height, and width. The right plant in the right location will perform for you and be less susceptible to insects and disease.
The second shopping secret is to know your garden. Are you planting in a sunny spot or on the shady side of the house? Would you like year-round interest from an evergreen or color in summer from a coneflower? Always have a plan or at least an area in mind when shopping for nursery garden plants. Know your site and your hardiness zone.
The best shopping secret for a beginner looking for nursery garden plants is to start small. Don't try to plant a large area if you are new to gardening; you will become overwhelmed. Try a shrub as a focal point with easy-care perennials such as Salvia 'May Night' and Rudbeckia 'Goldsturm'.
For the experienced gardener, try a new variety of a plant you love, such as roses—there are so many new colors and types to choose from. Every year, breeders introduce new varieties of shrubs and perennials, so there are always plenty of exciting plants.
It’s easy to go to a nursery and get overwhelmed or pick out some nursery garden plants that won't work well in your landscape. Besides site specifics, you should think about past results and cultivation needs before selecting plants at a nursery. If you're not sure of something, don’t be afraid to ask questions. Garden center staff and online retailers have all kinds of cultural information for you. Let them know if you have had poor results with a plant and they might be able to pinpoint what the problem was. Let them guide you through the process; everyone loves to talk about plants.
With all the information in hand—plan, nursery garden plant ideas for your zone—you can make your nursery shopping experience easier. You start with the nursery garden plant label. Everything you need to know about the plant—sun and shade needs, soil conditions, moisture, bloom time, mature growth size—is on that plant label. Using the plants' labels and your plan together is a great way to choose the best nursery plants. Take your time and figure things out so you come home with plants that have staggering bloom times, for example. If you’re new to gardening, don’t be nervous. Pierson makes the same mistakes as other people. “For example, I get really excited and want to have all these plants, so I put too many plants in and my garden gets overgrown quickly, which can lead to disease problems,” she says. Reading the labels helps prevent issues such as that.
Let’s say you need a purple coneflower and you have two pots of it side by side at the nursery. Here’s how to select the best plant: Start by looking at the roots. You should see some roots coming out of the drainage holes; that's a clue that the nursery garden plant is rooted, and roots are more important than top growth. If the plant is not rooted, it is less mature and will not transplant as well. If you can't see roots, gently pull the plant out of the pot to get a good look. Now, here's an easy-to-remember tip for choosing nursery plants: Some plants can be pot-bound if they have been sitting in the pot for a very long time. Brown roots are one indication that a plant has become root-bound. If you see roots girdling the pot and suspect the plant has been sitting in it for a long time, ask the nursery staff how old the plant is.
Bigger isn’t better when it comes to plant shopping. You should avoid tall, spindly plants—this is an indication that plants have been competing for light and resources. These plants will also struggle to transplant successfully.
You may be tempted to purchase a beautiful flowering plant if you spot one. However, it might not be a good idea to buy a nursery garden plant that’s flowering. Generally, a plant that hasn't been forced into flower does better than a plant that has been forced into flower. A plant that has a lot of foliage is better than a spindly plant with a flower on top. The same applies to seedlings that already have fruit or vegetables. Be patient; the blooms will come later!
If you plan to buy shrubs or trees, check their health first. A few telltale signs will help you judge. Make sure the tree or shrub is very full, with lots of stems. It should be rooted, which is particularly important for evergreens, and have lots of foliage on top. Then look for obvious signs of stress—brown leaves, spotted foliage, brown growing points, a top that doesn't look healthy. Those are your cues that a nursery plant hasn't been taken care of, says Pierson.
Last but not least, inspect the underside of leaves for pests. You don’t want to bring home an already infested plant or infect any of your established plants.
You’ve found a plant you love. If you’re a beginning gardener, your instinct may be to start with just one and see how it does in your yard. For perennials and annuals, however, it's always good to plant in groups of at least three. If you plant just one of too many different things, it looks funny. But drifts of color make a nice impact. So, another shopping secret that Pierson recommends is buying at least three of a single type of nursery plant. Plus, if you do get a bad plant, you’ll know it was that plant and not a problem with your garden.
Pierson admits that it can be overwhelming to make these choices, but there are a lot of resources that can help, and the secrets for shopping for nursery garden plants are things people can understand and remember. Do your research beforehand. Pick up a catalog, look at your landscape, and don't be afraid to ask questions. Plants change all the time, and nursery employees are there to help. If you do your planning before going to the nursery, it will pay off later.
