I decided to keep this list and the link that goes with it, I will add more charts with some easy and favorite bulbs
for all four seasons.

The list of plants in this
bulletin includes some that grow from corms and
tubers as well as those that grow from bulbs. Corms, tubers, and
food for the growing plants. All references to bulbs also include corms and
flowering bulbs are easy to grow, and do well in all parts of the
United States. Most of them are grown for their flowers,
some for their
Among the more popular summer flowering bulbs are tuberous rooted begonia,
gladiolus, lily, and caladium.

varies in height from 9 inches to 5 feet. Many
varieties are grown. Summer flowering varieties bloom
in June and July.
Flowers are white, red, yellow, blue, or pink. Use allium in borders. Some
commonly grown kinds
of summer flowering allium and their characteristics are
AzureumQDeep blue flowers; grows 2 feet tall;
blooms in July.
GiganteumQBlue flowers, 9 inches in diameter; grows 5 feet tall; blooms in
flowers; grows 15 inches tall; blooms in July.
Plant bulbs 2 or 3 inches deep in early spring. Space them 6 to 15 inches
apart in clumps of 6 to 12 bulbs. The distance between bulbs depends on the
height of the plant at flowering time.
the bulbs in place for many years. Dig, separate, and replant them when
they become crowded or produce small flowers.
grown for its showy, colorful leaves. The flower buds should be
removed as soon as they appear
so the leaves can develop fully.
Many varieties of caladium are grown. Dwarf varieties grow up to 9 inches.
Ordinary tall varieties grow up to 18 inches, and elephantUs ear grows up to
6 feet. Use caladium in front of
shrubs, as foundation plantings around the
home, land as pot plants.
Plant the tubers close together in a flat
from January to mid-May. Use a
mixture of peat moss and coarse sand. Cover the planted tubers with a 1-inch
of peat moss.
Water the tubers often enough to keep the soil mixture damp. Roots grow from
the tops of the tubers;
they must be kept moist and covered with peat moss.
Keep the room temperature no lower than 70 degrees F. Tubers often
rot in cool
As soon as roots develop, replant the tubers of elephant's ear outdoors or in
tubs or boxes;
replant the tubers of other varieties outdoors or in 6-inch
pots. Use a mixture of equal parts of garden soil and peat
moss. Grow the
plants in a lightly shaded area, never in direct sunlight. The leaves burn
Try to balance
the light and shade to get the most color in the leaves. When
plants are grown in deep shade, the leaves will have more
green coloring and
less pink or red.
Water and fertilize caladium at least every other week. Do not allow the soil
to become dry. Fertilize with a mixture of 1 teaspoon of 20-20-20 soluble
fertilizer per gallon of water.
the leaves turn yellow in the fall, dig the tubers from the garden and
store them with the soil around them. Store potted
tubers in the pots. Keep
the storage area dry and at no less than 60! F. Start the growing cycle again
the next year.
Many types of canna are grown. Tall types grow 5 to 7 feet high and dwarf
types, 18 to 30 inches. Canna
blooms for many weeks in summer. Flowers are
red, pink, orange, yellow, and cream. Use canna in flowerbeds.
rhizomes (underground stems) from March to May in flats filled with peat
moss. Cover the rhizomes with 1 inch of peat
moss and water them often enough
to keep the peat moss damp.
When shoots appear, replant the rhizomes in 4-inch
pots. Use a mixture of
equal parts of garden soil, peat moss, and sand. Leave the pot plants indoors
until all danger
of frost has passed. Then plant them outside in full
Dig the planting site thoroughly and mix well-rotted
cow manure into the soil.
Plant the rhizomes just below the soil surface. Space them 12 to 18 inches
and fertilize the plants at 2 week intervals throughout the growing
season. Apply a light ring of 5-10-5 or 10-6-4 fertilizer
around each plant.
Stake the tall varieties; they fall over easily.
After the first light frost, cut off the stems
of the plants. Then dig the
rhizome clumps and let them dry. Store them with the soil around them away
If your storage conditions are dry, embed the rhizomes in flats of
dried peat moss for the winter. The next spring, clean
the rhizomes and start
the growing cycle again.
grows 2 to 4 feet high. It blooms in summer and fall and produces
flowers of all colors. The kinds of
gladiolus that are commonly grown are
grandiflora, primulinus, primulinus hybrids, and colvilleii. Use gladiolus for
flowers or in flowerbeds.
Plant gladiolus bulbs in rows 36 inches wide or in flowerbeds. Prepare the
beds the year
before you plant, applying 1 pound of 10-6-4 fertilizer for each
100 square feet of planting space. Thoroughly mix the
fertilizer with the
Start planting as soon as the soil is dry enough to work in the spring. Plant
bulbs 4 to 7 inches deep and 6 to 8 inches apart. Continue planting every
7 to 10 days until early July; this assures
a continuous supply of flowers.
When shoots are 6 to 10 inches tall, fertilize the plants with 1 pound of
fertilizer per 100 square feet of space. Water the soil around the
plants every 10 days in dry weather.
North, dig the bulbs every year about 6 weeks after the plants have
bloomed. Wash the soil off the bulbs and spread them
in a shaded area to dry
for several weeks. In the South, gladiolus are left in the ground for several
they are dug.
When the bulbs are dry, separate them by size and keep only those that are
more than 1 inch in diameter.
Store them in a well ventilated area at 35 to 45
Lilium hybrids are among the most beautiful plants grown from bulbs. They have
many forms, heights,
flowering times, and colors. The most common types of
lilium hybrids and some of their characteristics are as follows:
candidum (white madonna lily)QBlooms in June; grows 3 to 4 feet tall;
fragrant flowers; plant in September.
excelsum (testaceum)Q Blooms in June; grows 5 to 6 feet tall; apricot
flowers; plant in light shade.
in July; grows 3 to 5 feet tall; white or yellow flowers.
Lilium speciosum and auratumQ Blooms in August and September;
grows 4 to 6
feet tall; many hybrids between these two types. Upright lilyQBlooms in June;
grows 21/2 feet tall; many
hybrids in this group.
Except as shown in the descriptions of the types, plant the bulbs in October
in a sunny, well-drained area. Plant them at a depth that is
three times the height of the bulb. Space the bulbs 6 to
18 inches apart
according to the height of the plants.
Water and fertilize the plants at frequent intervals during
season. Use a light ring of 5-10-5 or 10-6-4 fertilizer around each plant. Do
not use high rates of high
Remove the seed pods when they appear on the plants in the fall; seeds use up
plant food needed
for growth the next year. When the leaves turn yellow, cut
and destroy the stems and foliage.
Leave the bulbs in place
for 2 to 4 years. Dig the bulbs in late summer or
fall and replant them as soon as possible; they will not grow successfully
allowed to dry out excessively in storage.
