New Hampshire is known for cold, snowy weather, but that doesn’t mean your yard has to be barren during the winter season. You can brighten it up with beautiful winter plants that handle cold winters like a cool breeze. Check out these nine plants that flower in New Hampshire’s cold winters.

Blooming Winter Flowers

1. Cornelian Cherry (Cornus mas)

Blossoms in late winter, fruit in the summer — Cornelian cherry brings the whole package. Its fruit is quite sour, but it can be processed into jams, jellies, and syrups. If you want it to create a little privacy, that’s not a problem either; Cornelian cherry can grow up to 25 feet tall or be grown as a hedge. 

Fun fact: The shrub’s name is actually a misnomer; it’s not a cherry but a dogwood. Although it’s unsuitable for pets, you can certainly leave the fruit for local wildlife, like birds. 

  • Bloom time: Late winter to early spring
  • Hardiness zones: 4 to 8
  • Sun: Full sun, partial shade
  • Water needs: Keep the soil moist at all times; while growing, the tree needs frequent watering, but mature trees can usually live off rainwater unless the weather gets too hot or when there’s no rainfall
  • Soil: Slightly acidic to slightly alkaline, well-drained soil; preferably moist and organically rich, but tolerates clay-based
  • Duration: Perennial
  • Mature height: Up to 25 feet tall
  • Potential hazards: None known; can cause issues if eaten by pets, though

2. Daffodil (Narcissus)

Daffodil is a spectacular and hardy bulb that’s super easy to care for and thrives in a variety of soil types, making it a great choice for beginners and advanced gardeners alike. And of course, planting these daffodil stunners in your yard is a great way to brighten it up with a pop of color.

Originating in Europe and northern Africa, daffodils have spread throughout the world, including into New Hampshire gardens. Planted in the fall, typically in October, these blooms will spring to life late in the winter, providing a preview of all the beautiful spring colors that will soon adorn your landscaping.

  • Bloom time: Late winter to early spring
  • Hardiness zones: 4 to 8

  • Mature height: Up to about 16 inches

Known as Japanese andromeda or lily-of-the-valley bush, Japanese pieris is a popular evergreen bush that produces clusters of small, bell-shaped flowers in late winter to early spring. When it gets warm enough, the flowers attract bees. 

As one of its names suggests, its flowers resemble lilies of the valley, although their fragrance is not as strong. Also, take note that this bush is more suitable for the southern part of New Hampshire.

Nevertheless, the Japanese pieris is a striking showpiece that can be used as a focal point in a garden or as a hedge. Shorter cultivars are also available for smaller spaces.

  • Bloom time: Late winter to early spring
  • Hardiness zones: 5 to 8
  • Sun: Full sun, partial shade
  • Water needs: Keep the soil moist at all times; water to about 3 inches deep once a week if there’s not enough rainfall

  • Duration: Perennial
  • Mature height: 9 to 12 feet tall
  • Potential hazards: Severely toxic; be careful with your children and pets

They especially stand out in a group setting. Plus, ornamental kale and cabbage can look great as a garnish on your dinner plate.

  • Bloom time: From fall to winter
  • Hardiness zones: 2 to 11
  • Sun: Full sun is ideal in New Hampshire, but some partial shade is OK, especially in warmer climates

  • Mature height: 12 to 18 inches tall and wide

This ground-hugging plant stands out for its yellow, buttercup-like flowers that provide a source of nectar for bees when they become active. Native to southeast France, winter aconite is a great way to add a splash of color to walkways, rock gardens, beds, and woodland gardens.

If you’re in the south of New Hampshire, plant winter heath, a purple, pink, or white evergreen shrub that’s sure to brighten up your yard during the cold months. This early winter bloomer is easy to care for and thrives in the sun. 

It can also tolerate a little shade, but it may make its stems too long, affecting its appearance. Be sure not to fertilize this plant; it has a symbiotic relationship with soil fungi, so it gets enough nutrients unless it’s in a pot.

  • Bloom time: Early winter to early spring
  • Hardiness zones: 5 to 7 (some cultivars may live in zone 4)
  • Sun: Full sun
  • Water needs: Once or twice a week during the first season, when soil is dry; mature plants rarely need watering as they become resistant to dry conditions

  • Potential hazards: Some reports of toxicity; practice caution
