What Flowers to Plant in March (Zones 1-10)

What flowers to plant in March? Let’s fill you in if you aren’t familiar with the zones people use as a guide for starting to grow veggies, fruits, and flowers. Please keep in mind that flowers attract bees and help pollinate our gardens, a key to successful gardening.

Garden zones are how you know what and when to plant seeds, seedlings, or plants. The USDA Hardiness Zone Map has 10 different zones. I know the zones have changed a bit with different temperatures these days which may be due to climate change, so we must learn to work around it. Keep checking your weather before planting outside.

If we have flowers, the bees will come. We need them to pollinate our vegetables in the garden. Oh, and don’t forget the Hummingbirds and butterflies! This is where I buy my seeds: SeedsNow.

What Flowers to Plant in March

Check out the zones to see which zone area you’re living in. Each zone is 10 degrees warmer or even colder than the average winter in an adjacent zone. So, what flowers should you plant in March? Let’s get started!

Zone 1-4

Let’s be honest: If you live in Zone 1-2, finding flowers that survive those cold months will be hard. However, some plants will make it through colder weather. I wanted to talk about some of these plants since there aren’t many flowers for planting in March for these zones. These plants are hardy, which you need when planting in March:

• Coneflower – Hardy to zones 3 and 4
• Lily of the Valley – Hardy, but needs partial sun. 
• Hostas – Zone 3 
• Winterberries – Zone 2 
• Primrose – Zones 3 and 4
• Blue spruce – Not quite a flower, but it will last in Zones 2, 3, and 4. 
• Pansies- Zone 4 
• Catmint – A resilient plant that you can try planting in March.

March, when it warms up, is a great time to start prepping your flower garden for spring. While you can’t plant much in these zones in March, you may have a warmer year and be able to plant quite a bit. 

Zone 5

Thank goodness that Zone 5 looks a little more promising for planting flowers. At least 14 perennials grow in Zone 5 which is great since you don’t have to replant them each year. While this zone isn’t the coldest or warmest, it can still produce some awesome plants!

Final Word

You can play around with what flowers to plant in March, but this is a good baseline. Flowers can be tricky because if it’s a colder than typical winter, the flowers may not grow. Pay attention to what worked for you in the past and what didn’t, and keep some notes for future use. Happy Gardening!! May God bless this world, Linda
