What Are White Winter Plants?
Winter white flowering plants are annual perennial plants that grow, produce new seeds, and die within a year while some grow back the following year.
In the United States, winter starts on 21 or 22 December and until 20 or 21 March. White winter plants are winter plants and shrubs that bloom from the end of November until the beginning of February.
A similar characteristic of these winter plants and shrubs is their hardiness, the white winter plants are robust and tolerant of extremely low temperatures despite having delicate flowers.
7 White Winter Plants
1. Winter Jasmine White
Winter jasmine white description:
Winter jasmine white pink buds open to the clusters of distinctly fragrant white flowers, which bloom during late and early spring.
Winter flowering jasmine white climbs on trellis around 10 feet or more under partial shade or full sun.
When to plant winter jasmine white:
To ensure strong root development, spring and autumn are the best seasons to plant the winter flowering jasmine white.
How to grow winter jasmine white:
Winter jasmine white plants can grow as tall as 15 feet with support and as tall as 4 feet and as wide as 7 feet without support.
Space out each winter flowering jasmine white by 4 to 5 feet to encourage optimum growth. Add climbing support.
Add mature compost for the winter jasmine white to thrive in the garden. Insulate the outer pots with jute sacks to avoid frost damage.
Avoid overwatering since winter jasmine prefers drier soil. So, water the plant only once a week.
Repotting winter flowering jasmine white in autumn for better bloom. Winter jasmine white blooms in late winter and the flowers will appear before the leaves.
The layering technique is used to propagate winter jasmine by lowering a plant shoot into the ground for new roots to grow while still attached to the parent plant. Separate the shoot after it gains a root system and replants at the new spot.
Harvest the blooms before the flower buds are fully opened in the morning or evening. At an angle of 45 degrees, prune the base of the winter jasmine branches and place it in a vase filled with water.
How to care for winter jasmine white:
Fertilize your white winter plants in spring and summer. Potassium fertilizer increases frost hardiness and pest resistance to the winter jasmine plant.
Nitrogen fertilizer enriches the winter jasmine leaves whereas phosphorus fertilizer aids in lusher blooms.
Regular pruning to trim the leaves neatly can be done with cordless pruners to help maintain the winter flowering jasmine white plant growth.
After the white winter plants’ major bloom cycle, use your best gardening gear to prune until only the young shoots are left for lush flowering in the following year.
Winter jasmine white diseases and solutions:
The white winter bedding plants are deer resistant and loved by bees, aphids, and mealybugs.
Foliar, blight, and fusarium wilt lead to necrosis with discolored halos on the stems and wilted leaves.
Isolate the affected plants first. Remove the damaged and infected plant parts including picking up and disposing of the dropped leaves. Repotting the plant in a new pot with fresh soil.
Use baking soda, neem oil spray, and fungicides to treat the diseases of winter white flowering plants. Avoid overhead watering since the leaves must be kept dry.
The fungus infects winter jasmine white during the moist period while pests attack during dry time.
Yellow or pale green stunted leaves indicate chlorosis. Chlorosis happens due to iron, zinc, and manganese deficiency. Apply chelated nutrient foliar spray to the plant.
Due to insufficient or excessive amounts of water, the flowers of winter jasmine turn brown, form spots, and fall. Make a berm or ridge in doughnut form around the plant at 2 to 3 inches high to entrap rainwater and release it slowly into the ground.
Excessive nitrogen in the soil causes the falling of winter jasmine flowers. The solution is to dilute the excess nitrogen by adding root mulch, wooden sticks, and sawdust to the soil bed.
Due to extreme temperature changes, the flowers may die and fall if the flowers are not pollinated. To aid the pollination process, rub the stigma and anthers of the flowers using a new toothbrush from one flower to another to distribute the pollen.
2. White Winter Pansies
White winter pansies description:
The genus name for white winter pansies is Viola x wittrockiana. Its common name is extra-large flower pansies.
Pure white flowers of matrix white pansies have amazing cold tolerance.
When to plant white winter pansies:
If you plant in October or November, grow white winter pansies outdoors first in pots or seed starter trays for about 4 weeks before planting them in their final growing place for winter or autumn, or early spring flowering.
To plant your white winter pansies from the seed, start indoors either in late summer for winter and autumn flowering or in late winter 8 to 10 weeks before the spring for early summer and spring flowering.
How to grow white winter pansies:
Buy white winter plants from the local nursery if you want to enjoy earlier blooms, rather than starting from seed as it takes 1 to 3 weeks to germinate.
White flowers that grow in winter love partial shade or full sun. So, the ideal spot for white winter pansies is where it can get morning sun, yet shaded from the late afternoon heat.
For pansies in portable pots or containers, the pansies must face the south in early spring or fall and move the pansies to face the east during the summer.
Pansies are ready for final planting when their roots touch the sides of seed starter trays. Plant your white winter pansies around 7 to 12 inches apart from each other as they will grow to 6 to 9 inches tall.
To encourage longer-lasting flowers and bigger flower blooms, apply a good feed at a 14-day interval.
How to care for white winter pansies:
Remove the dead flowers to encourage better longer lasting blooms. Do not use high nitrogen fertilizer excessively as it can result in more foliage, instead of flowers.
White winter pansies diseases and solutions:
Black root rot and Pythium root rot diseases happen due to poor drainage, poor sanitation practice, overwatering, and debris. Infected black root rot appears stunted or wilted, developing dark spots on the white pansy roots.
Fungicides, new single-use pathogen-free potting mixes, new containers, nitrogen fertilizers, and good sanitation reduce winter pansy root rot diseases.
Pansies that are affected by genetic mottle pansy syndrome have contorted leaves. It appears normal during the daytime when the temperature is near 80℉ and the night temperature is cool.
The contorted leaves return once the pansies are placed outdoors. The best way is to discard the affected pansy leaves.
3. Winter White Gardenia
Winter white gardenia description:
Gardenia jasminoides ‘frostproof’ is the genus name of winter white gardenia. Winter white gardenia has creamy white flowers and emits a fragrant scent at night.
When to plant winter white gardenia:
Plant winter white gardenia during autumn or spring to provide sufficient time for the root to harden before winter.
How to grow winter white gardenia:
Winter white gardenia can grow as tall as 5 feet or more and 3 to 4 feet wide if left untrimmed. It grows best when the daytime temperature is between 65℉ to 70℉ and night time temperature is between 60℉ to 65℉.
When planting winter white gardenia, dig holes that are twice wide and deeper than the root ball. Space out 2 to 2 ½ feet from each plant for hedge-type planting or 5 feet apart on white winter bedding plants ground.
Add manure compost to the site before planting winter white gardenia. Water it before putting pine straw or compost around the plant.
These winter white flowering plants can tolerate 28℉ to 32℉ temperature during the mild freeze, 70℉ to 75℉ in the daytime, and 60℉ at night time.
Cover gardenia plants with a transparent frost-proof cover or cardboard box to protect the branches from breaking due to the snow weight.
Winter white gardenia starts blooming in mid-May and continues blooming until late summer and early autumn in warmer climates.
To propagate gardenia, cut 4 inches of stem below the leaf in early spring and dip its end in root hormone. Leave the cutting in mixed perlite and potting soil pot. Transplant the cutting into a bigger pot once the root forms.
When harvesting, do not touch the gardenia blossoms with bare hands as they may wilt or bruise. Cut the stems at 45 degrees angle to absorb water and remove all bottom leaves.
How to care for winter white gardenia:
Gardenia plant needs more care than other white flowers that grow in winter.
Keep winter white gardenia soil moist to avoid root shrinkage and cracking. Do not fertilize the plant in autumn or summer and right after transplanting as it contributes to the spurt of frost-tender growth.
Prune winter white gardenia by two third of the new growth in autumn or late summer after flowering has stopped. When the branch tip becomes black from frost or dying, prune 5 centimeters below the damage with sharp pruning shears.
Winter white gardenia diseases and solutions:
Powdery mildew, root rot, stem canker, mealybugs, white flies, aphids, nematodes, and spider mites affect winter white gardenia. Colder temperatures cause winter white gardenia leaves to burn, buds to drop, and other damage.
Water the gardenia first before applying insecticidal oil on the leaves to control spider mites.
4. White Winter Aconite
