For plants, dormancy declares when to prepare their soft tissues for freezing temperatures, dry weather, or water and nutrient shortage. Instead of exerting energy in an attempt to grow, they know to stop growing and conserve energy until mild weather returns.
Some, however, such as snowdrops and bluebells, have carved out a niche that allows them to gain a step up over their competitors. By flowering in winter, they are able to survive quite happily in real-estate that most plants can't - that is, under the heavy bows of large deciduous trees, deep inside the ancient woods.
In warmer zones, the winter planting window is wide open. You can sow seeds for winter vegetable crops, like salad greens, radishes, carrots, onions, Swiss chard, English peas and kale. Look for transplants of other cool-season vegetables, including Brussels sprouts, broccoli and cauliflower.
Keep them away from direct sunlight and heat vents, as well as cold drafts near a window or door in winter. Avoid placing your arrangement near ripening fruit, which releases tiny amounts of ethylene gas that can age flowers prematurely. And finally, most cut flowers benefit from a daily mist of water.
Galanthus. Galanthus, also called Snowdrop, are droopy, bell-like flowers that grow anywhere from six to 10 inches tall. This perennial enjoys cold to moderately cold winters and will even sprout up through the snow.
Plants are dormant in the winter, which means they are not actively growing.
The golden trumpet is a flower that can bloom all year round. Apart from its beautiful appearance, this all-year flowering plant is used to kill bacterias and reduce swellings. It is scientifically known as Allamanda cathartica and is native to Brazil.
Generally, roses bloom between spring and autumn. Though, different types of roses have different blooming seasons and some rose types can even bloom in winter.
Snowdrop. Just as the name indicates, these tiny flowers appear when snow is still on the ground in cold climates. Snowdrops, also called galanthus, look delicate but are quite cold-hardy.
The optimum storage temperature for most non- tropical cut flowers is between 33°F and 35°F. Every degree above this range decreases vase life and increases respiration rate.
For most flower types, optimal storage temperatures range between 33°F - 37°F while cold-sensitive blossoms and tropical flowers should be maintained at temperatures above 50°F.
Those flowers may have looked good when you first received them, but despite your best efforts, you can't keep them fresh forever. If you really want to preserve your blooms, you need to remove their moisture with a process like air-drying, pressing, or nuking them in the microwave.
Unlike plants that are strictly 'annual' (meaning that they live for one year and then die), the roots of perennial flowers survive through winter, allowing the plant to come back up in the spring. Because of their durability, perennial plants are the favorite of gardeners around the world.
Flowers are full of moisture, which will freeze when they are placed in a regular freezer. If you just want to leave the flowers in the freezer forever, then you can use a household freezer—but if you want to take them out to admire them later, you'll run into problems.
Name: Helleborus sp. commonly known as winter rose or Hellebore. Belongs: to the buttercup family Ranunculaceae. Origins: Europe to western China. Flowering: Winter to early spring.
The snowdrop flower. As a plant that actually despises warm winters, the snowdrop flower performs its best in frigid temperatures. This flower can withstand temperatures down to -30 F. while still displaying its bright green stems and delicate, white flowers.
According to Myers, the hardiest vegetables that can withstand heavy frost of air temperatures below 28 include spinach, Walla Walla sweet onion, garlic, leeks, rhubarb, rutabaga, broccoli, kohlrabi, kale, cabbage, chicory, Brussels sprouts, corn salad, arugula, fava beans, radish, mustard, Austrian winter pea and ...
Daffodils, crocuses and tulips
Hardy all the way to zone 3, they actually do better with cold winters. These plants need cold weather to bloom well in the spring, thanks to a chemical reaction that takes place when the soil temperature is below 55 degrees, according to the Amsterdam Tulip Museum.
