Often associated with bees, birds, and other springtime wonders, there are a number of types of flowers to plant in March. While many bulb flowers should’ve been planted at this point in the year, a great deal of other types of flowers do well when planted in March. But what sorts of flowers should you consider planting in March and how can you best care for them?
Given the fickle nature of the weather during the month of March, knowing your Hardiness Zone and local temperatures is key to any successful planting. However, many flowers thrive in uncertain conditions, including daisies, marigolds, salvia, and petunias. Other flowers will need to be started from seed indoors, such as snapdragons and petunias.
In this article, we’ll go over seven of the best flowers to plant during the month of March, whether you need to plant them indoors or out. Not only will we address tips on where to best plant these blooms. We’ll also give you some information on the varieties and types available. Whether you’re a gardening expert or a novice, most of these flowers are simple and easy to grow. Let’s get started!
The Best Flowers to Plant in March
As previously mentioned, it’s important to take your local weather into account before planting anything during the month of March. While this time of year starts to feel like spring, it can still be a tumultuous time for winter storms and freezing conditions. Unless you live in a consistently warm Zone, practice patience and endurance when it comes to planting things in March!
From cold-hardy beauties to wildflowers with style, what might some of the best flowers to plant in March need to thrive? Let’s talk about some of the most stunning options now.
There’s nothing like a tall and stately snapdragon. Unique and available in many different colors, bloom types, and disease resistance levels, snapdragons are a very popular annual. Plus, some snapdragons are considered perennial varieties, hardy enough to thrive in Zones 6-11. While you may be unsure which snapdragon variety grows best in your area, choosing an aesthetic option that you enjoy first and foremost is often the best way to go!
Depending on the size and type of snapdragon you choose, they may need support as they grow. Many snapdragons grow spindly or leggy without too much sun, so keep this in mind when choosing a site for them. Finally, plan on starting your snapdragons indoors roughly a month or two before you final spring frost date, and harden them outside before planting in your garden. You can also always plant your snapdragons in a container!
Depending on your region, you may be able to plant zinnias in March. Popular for their fast growth and multiple blooms, zinnias can be purchased in plenty of colors. They also last a long time, from spring to fall. While zinnias are annuals, they bring plenty of cheeriness to your garden and are a great flower to companion plant near your garden.
Zinnias are a favorite of many pollinators, including butterflies. There are single, semidouble, and double zinnia varieties, giving you plenty of choices. Plus, they aren’t very picky about their soil types, but they very much need full sunshine. Lastly, you can grow zinnias indoors from seed, but they can be tricky to transplant, so direct sowing may be your best option.
Another very forgiving flower to consider planting in March has to be the daisy. Daisies thrive in a variety of soil conditions and grow best as annuals, though some varieties are perennial in nature. Shasta daisies are one such perennial, thriving in Zones 3-10 and coming back year after year. English daisies and oxeye daisies are also popular daisies to plant in March.
You can grow daisies directly in the soil, but make sure to only do so in full sun. Growing seedlings indoors is also common, as some daisy varieties can even be grown year-round in containers and brought indoors. It all depends on the size, color, and growing method you want, but most daisies are seriously easy to grow!
Often confused with calendula, there are many reasons to love marigolds. For one, these orange and red beauties smell pleasant, attract pollinators, and grow easily in a variety of soil conditions. They also come in a variety of types and species, giving you plenty of options in terms of their cold hardiness and ability to survive the tempestuous climates found in March.
Marigolds are simple when directly sown outdoors, as soon as the soil is moderately workable. You can scatter plenty of marigold seeds in your garden and watch them go! Some compost may help improve flower production, but full sun is a must. Finally, marigolds are similar to daisies in that deadheading or completely removing all dead flowers helps them continually produce until fall.
Like zinnias, salvia flowers attract just about every single type of pollinator, but they repel deer and rabbits. This makes them ideal when paired alongside your vegetable garden, but you may find that salvia looks best in a container on your patio. With tall stems covered in blooms, salvia looks more natural and wildflower-like compared to many other flowers on this list.
You can directly sow salvia after frost dangers have passed, which may mean that March is a bit too early depending on your Zone. However, salvia is hardy in Zones 4-11, making this an incredibly hardy plant! Make sure to pay special attention to its sage-like foliage, given that it can be susceptible to many diseases. Speaking of sage, did you know that salvia and sage are closely related?
Just like snapdragons, petunias should be started indoors rather than directly sown. While sowing them in soil outside is possible, this is best accomplished during another, warmer month. No matter which method you choose, keep in mind just how small petunia seeds are. They are best sown on the surface of your garden soil, which can cause them to blow away with ease!
Petunias look beautiful in containers, hanging baskets, and as a border flower. Like most flowers, they need full sunlight in order to produce en masse, especially if you have a carpet or groundcover variety. Plus, petunias can even be grown as perennials, but only if you live in a warmer climate (such as Zones 9-11).
With sweet smells and delicate, unique vining flowers, sweet peas are a perfect flower to consider planting in March. In fact, sweet peas require cold temperatures in order to properly germinate, which means you may need to plant them right away! Hardy in Zones 5-8, sweet peas bring plenty of flowers and do best when picked frequently. Given that they’ll need a trellis for support, sweet peas are the most complicated flower to grow on this list. However, they are well worth the extra supplies!
