Best Ornamental Flowering Plants for the Winter Season
Winter can be harsh, making your garden bleak. Brighten your garden with plants that bloom during winter. Here is a selection of ornamental flowering plants that bloom during winter adding a splash of color to your garden.
The calendula (Calendula officinialis), commonly called the pot, marigold is an easy to care annual plant that blooms during winter. The flowers of these plants are long lasting and brighten the garden during the winter season.
The calendula is a flowering herb that needs little care. It can grow in poor to average soil conditions and needs a little watering when the soil becomes dry. The flowers bloom in colors of bright orange and yellow and can last long after the onset of winter.
It can bloom from spring through fall and winter if deadheaded regularly. Pinching off spent flowers will help to extend the blooming period.
The roots of the calendula plant adapt quickly to the space provided and can be grown in containers or beds. The flowers last longer in shady areas since the calendula prefer cold temperatures. Calendula can be directly seeded outdoors after the last frost. Adding mulch to the soil helps to keep the soil moist.
The carnation (Dianthus caryophyllus) is a herbaceous perennial plant with purplish pink flowers and leaves that are greyish green to blue-green. The flowers are sweetly scented and grow up to two centimeters in diameter and bloom during the late spring. The plant varieties that are grown from dianthus bloom in shades of red, pink, white, yellow, and purple.
Dianthus caryophyllus grows to a height ranging between 15 to 18 inches. These plants flourish in fertile, well-drained alkaline soil. Water the plants when the soil is dry and apply fertilizer every six to eight weeks. Plant carnations in areas that will receive four to five hours of sunlight for best growth.
These plants need air circulation around the stems at all times. Do not overwater dianthus, as this will lead to yellowing of the leaves. Prune the plant to the size and shape that you prefer. Pinching plants back stimulates new growth and encourages the flowers to bloom.
Remove spent flowers for the best display of your garden. Sow the seeds before late frost with a spacing of 6 to 10 inches.
3. Winter Aconite
Winter aconite (Eranthis hyemalis) is a tuberous perennial that grows in clumps up to a height of 4 inches. The flowers are cup-shaped, bright yellow surrounded by leafy bracts. The leaves are rich green and divided into several lobes.
These plants grow well in fertile, alkaline, and well-drained soils in full sun or partial shade. Winter aconites look stunning in garden beds, along paths, rock gardens, or as groundcovers.
Winter aconites can be propagated through seeds by sowing them in containers in a cold frame in late spring or through tubers after flowering in late spring. Soak the tubers overnight before planting.
The winter aconites bloom in February to March and survive sleet and snow. It is one of the earliest bulbs to bloom.
4. Christmas Rose
Christmas rose (Hellebores niger) is a hardy evergreen perennial plant that can withstand temperature as low as 5°F. It blooms in the middle of December. The flowers are large, saucer-shaped, and white or a pinkish white. The leaves are dark green and leathery.
The Christmas rose is a small plant that grows up to 0.3 meters in height and 0.45 meters in width. It is a clump-forming plant that grows well in heavy, neutral to alkaline soils in partly shaded areas.
Plant the Christmas rose from fall to spring avoiding the deep cold weather. It grows well in rich, well-drained soil. Add organic matter to encourage blooming. Remove wilted flowers and damaged leaves. Propagate this plant by separating the young shoots that appear around the clump.
5. Oregon Grape
Oregon grape plants (Mahonias aquifolium) are easy to grow evergreen shrubs with leathery, dark green leaves. These plants produce clusters of long stalks with lightly scented yellow flowers that turn into dark purplish berries.
The Oregon grape can grow to a height ranging from 3 to 10 feet tall and 2 to 5 feet wide. They grow well in moist, well-draining soil that is acidic or alkaline. These plants flourish in partially shaded areas but can also grow in full shade. Too much sunlight can scorch the leaves.
The Oregon grape can be propagated through seed germination, cuttings, or by dividing the existing plant. You can prune the plant once it finishes blooming.
Pansies (Viola x wittrockiana) are fast-growing plants that can survive temperatures below 32°F. These plants grow from 6 to 9 inches in height and spread to a width of 12 inches.
The flowers are mildly fragrant, have five petals, and are entirely yellow or yellow with black lines radiating from the center. Some flowers have “faces” in the center.
Plant the pansies from September to October, as the roots of pansies grow during warm winter days. They prefer full to partial shade with well-draining soil with a pH of 5.4 to 5.8. Add organic mulch to the soil bed, and plant them 6 to 10 inches apart so that they can spread without being crowded. Remove faded flowers to encourage blooming.
You can choose from many varieties of pansies that bloom in different colors to plant in your garden. Pansies can be easily propagated through seeds.
