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

3. Japanese Pieris (Pieris japonica)
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.

5. Sieber’s Crocus (Crocus sieberi)
These blooming beauties will adorn your yard with purple flowers in late winter to early spring. Sieber’s crocus is not just a real beauty, but it’s also resistant to cold and snow. These flowers have even been known to pop up amidst a snowy garden.

7. Winter Aconite (Eranthis hyemalis)
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.
The lovely winter aconite likes to peek through blankets of snow, cheerfully signaling the end of winter and the arrival of spring. It’s likely to spread throughout your garden, so you’ll need to keep it in check.

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.

- Potential hazards: Some reports of toxicity; practice caution
9. Winter Jasmine (Jasminum nudiflorum)
If you’re in southern New Hampshire and want your yard to be covered in delicate yellow flowers throughout the winter, consider planting winter jasmine. This plant grows as a groundcover or climbs up to 15 feet on a trellis. While it’s non-fragrant, it can cheer up your outdoor area with its green foliage and late-winter blooms.
This stunner of a plant is sometimes confused with the similar-looking forsythia, but unlike forsythia, winter jasmine blooms in the winter and isn’t known to be toxic.

- Sun: Full sun, partial shade
- Water needs: Higher than average, top of soil must not be dry; water once a week; more frequently during the summer when the weather gets hot
