Sunny Summer Sunflowers
Traditional stately sunflowers (helianthus annuus) with their bright yellow
blossoms are old garden favorites.
Hybridized Russian and Israeli varieties which have superior large grey
and white striped hulls are commercially grown in vast fields throughout the
US and into Canada. The seed is used as feed, the production of sunflower oil
and many other consumer products.
They will happily grow in natural soils in all but the most northern climate
zones. Improving the soil with manure and/or compost is recommended to facilitate
strong healthy growth.
Recent cultural developments for the garden enthusiast include colors ranging
from white to brown. They also come in a variety of sizes from miniatures of
about 2 inches across to giants up to 8 foot tall with bloom the size of
dinner plates that can produce extremely large seed heads.
Sunflowers can be used as background plantings where the larger varieties will
make a spectacular and effective screen for very little money. Smaller plants
are suitable for the flower garden or borders. The smaller varieties also make
lovely bouquets to display in your home.
Sow sunflower seed when weather permits in early spring - right where they
are expected to grow. Any average garden soil will do so long as they are
planted in sunshine and are kept reasonably moist. Plant seed about 1/2 inch
deep and 8 to 12 inches apart, depending on the variety. Once well established,
an application of fertilizer will greatly benefit them and help to increase
flower production.
Keep in mind that the sunflower is phototropic. This means that the flower
buds will follow the movement of the sun from east in the morning to west in the
afternoon. When flowers are fully open, they will usually remain facing east.
You can easily collect sunflower seeds for planting next season or to feed birds
during the cold winter months. You may also want to save some of the larger
varieties for yourself. A simple method is to tie a piece of cheesecloth, fine
nylon or plastic mesh around the ripening seed head when the back portion of
the head begins to turn brown. This will prevent birds from harvesting the seed
before you do.
Once the seed head shrivels and the seeds are dry, just rub them
into the covering. At this stage, the plants will probably have become
unsightly. You can now cut the stalks at ground level and dispose of them or chop them up and put on your compost pile.
