Sunflowers are annuals with showy, daisy-like flower heads that are usually 2-4 inches across and bright yellow (though occasionally red). Tall and course, the plants have creeping or tuberous roots and large, bristly leaves. Today, varieties have even been developed for small spaces and containers.
Most sunflowers are remarkably tough and easy to grow as long as the soil is not waterlogged. Most are heat- and drought-tolerant. They make excellent cut flowers and many are attractive to bees and birds.Smaller plants with big-time flower power. Striking compact, low-growing sunflower fills vase after beautiful vase with luminous, long-stemmed, brown-eyed, golden flowers.

Planting and care
- Water plants deeply but infrequently to encourage deep rooting
- Feed plants only sparingly; over-fertilization can cause stems to break in the fall
- Tall species and cultivars require support
- Bamboo stakes are a good choice for any plant that has a strong, single stem and needs support for a short period of time
Sunflower Large Bloom care
- Sunflowers grow best in locations with direct sun (6 to 8 hours per day); they prefer long, hot summers to flower well
- Sunflowers have long tap roots which need to stretch out so the plants prefer well-dug, loose, well-draining soil; in preparing a bed, dig down 2 feet in depth and about 3 feet across to ensure the soil isnâ€™t too compact
- Find a well-drained location, and prepare your soil by digging an area of about 2-3 feet in circumference to a depth of about 2 feet
- Though theyâ€™re not too fussy, sunflowers thrive in slightly acidic to somewhat alkaline (pH 6
- 0 to 7
- Sunflowers are heavy feeders so the soil needs to be nutrient-rich with organic matter or composted (aged) manure
- Or, work in a slow release granular fertilizer 8 inches deep into your soil
- If possible, put seeds in a spot that is sheltered from strong winds, perhaps along a fence or near a building

- You can begin to enjoy the bright sunflower blossoms several months after you planted seeds, but you will have to wait another month or so before you can eat sunflower seeds.
- Although the exact timetable varies among cultivars, harvest time usually rolls round toward the end of summer.
- For cut flowers, remove 1 foot or more of stem with the flower and plunge it into hot water immediately to draw out air.
- For edible seeds, you must harvest the flowers after the leaves shrivel but before the seasonal rains.
- The flower heads with 1 to 2 feet of stalk must spend another month hung in a dry, well-aired spot before you extract the seeds.
