Begonia originated in the rain forest in South America. The name ‘begonia’ comes from Michel Begon (1638-1710) an amateur French botanist who first collected
them. These flowers are grown from tuberous roots. New growth buds appear on the base of the old stem, at the point where it joins the tuberous root. Begonia like cool, moist, lightly shaded places where the soil is rich and well supplied with humus.Flower heads have one large double male flower in the center, with two single female flowers at the sides. Flowering is stimulated by long day lengths, common during the summer in Alaska.

Dahlia (Compositae)
Dahlia are an important group of tuberous-
rooted plants of the family Compositae
(sunflower family). The forms used in gardens today originated from Mexico, Guatemala and Central America. The Spanish travelers brought a handful of tubers back to Madrid in the late 18th century.
The Swedish botanist Andreas Dahl, named them. In 1826, English plantsmen had hybridized nearly 60 kinds. Today there are over 1700 recognized varieties.
Dahlia are among plants that have evolved underground tuberous roots to store food and survive through adverse conditions. The first year a dahlia plant is grown from a seed, it will develop a branched tuberous root system that can be easily overwintered in cool storage.
The tuberous root can be replanted whole or split, making several plants. Each one of the tuberous roots attached to part of the stem will produce buds, from which new plants can grow. The buds will be formed at stem end or where the old stem was.
Dahlia thrive best in well-drained soil. They like plenty of water after beginning to bloom, but like roses and peonies, seem to resent “wet feet

Overwintering fuchsia & geranium
The contained plant can be overwintered in any dark, cool place that is 40° F and frost free. The soil must not be allowed to dry out.
Bring the plant indoors before the first frost is expected. Pruning the plant back prior to overwintering will reestablish a centrally located scaffold for new growth.
This will result in the formation of a full, compact plant when growth resumes. Remove
all the green and red stems, leaving the tan hardwood. Remove all the leaves. Water to keep the plant slightly moist but not wet during the winter.
Early next spring, perhaps as early as mid-to-late February, new growth should start appearing. When this happens,
increase moisture and return it to the growing conditions the plant prefers increased light and warmer temperatures.
When new growth starts, it will often produce single stem branches. If left to continue, this would result in a sparse, leggy plant. Pinching the growing
tips early will promote branching, and the result will be a plant that fills and covers the container.
There are various ways to overwinter geranium. One method is to pull plants from the garden and remove as much soil as possible. Hang the plants upside down in a plastic bag with holes, containing
wet peat moss, in a cool location.
They can also be left in the pot and treated like fuchsia.

Geranium
(Pelargonium sp.)
Garden geranium are not really a geranium
but a Pelargonium. They originated from South Africa. Geranium are a favorite
plant for gardeners all over the world. Most plants are propagated from stem cuttings which easily root in water or moist sand. The seeds are difficult to germinate
because of a hard seed coat. Scarification
or nicking the seed coat greatly speeds germination.

Fuchsia
There are more than one hundred species of fuchsia, comprised mainly of perennial
trees and shrubs. These plants are all members of the plant family Onagraceae; the evening primrose family.
The fuchsia is very adaptable to much of Alaska’s outdoor growing conditions. It prefers a daytime temperature of 60 to 70° F and a nighttime temperature of 50 to 65° F. The cool night temperatures are especially important during the early growth of the plant when new growth is pinched and flower buds are developing. It also does very well in filtered sunlight or semi-sunny
conditions often associated with locations along buildings where hanging baskets are placed for aesthetic appeal.
A continuous blooming hanging basket of fuchsia provides a great amount of beauty to its surroundings. The proud owner will often want to have this growth and beauty available from the same plant the following season.

General growing requirements
Maintaining a vigorous, healthy plant during the growing season is one of the first requirements necessary to ensure that the plant can survive the long period
of rest or dormancy. A perennial plant must be able to produce sufficient
growth and food reserves if it is to maintain itself and put forth new growth again the following spring. During the growing season, fertilize weekly with a weak complete
soluble fertilizer high in phosphorous
such as 15-30-15.
These flowering plants may continue to produce
an abundance of flowers until frost stops all further growth and activity.
In preparation for the approaching season’s
end, you should cease fertilizer applications
at least two weeks before you anticipate bringing it indoors. Watering should be reduced to a great extent, but not to the point where the root system will die.

Growing and Overwintering Fuchsia, Geranium, Dahlia
Fuchsia, geranium, dahlia and tuberous begonia are perennials that will not overwinter
outside in Alaska. These plants are native to much warmer climates. Special care and an indoor overwintering site are required to keep these plants from year to year in Alaska. The extra work does have its rewards: each of these plants have large showy flowers.
