This is one of the tallest sunflower varieties in the world. Huge 9 to 12 foot stalks adorn bright and sunny blooms that are around 1 foot in diameter. Each stalk typically produces one bloom. They start blooming at about 3 months from seed. Each head will produce a ton of seeds for human and bird consumption. After blooming, the stalks and leaves offer a lot of biomass to be used for composting or mulching. 

How To Grow From Seed

Sun: Full Sun

Water: Allow the soil to dry out a little bit in-between watering. Established plants are drought tolerant. 

Fertilizer: Doesnt require a lot of fertilizer since this is a wildflower. Can give it some organic granular fertilizer every now and then to promote lush growth and blooms.

When & How To Sow Seeds: Can direct sow 1/2 inch deep, after the last frost or start in larger sized pots 6 weeks before your last spring frost date. Direct sowing is preferred because sunflowers grow a long tap root. Space 2 FT apart for good air circulation. Plants will get around 6FT tall at maturity. It helps to direct sow the seeds next to a fence or structure for support as tall sunflowers can blow over from strong winds. Direct sow in a spot that gets full sun, covering with 1/4 inch of soil. Keep the soil moist to speed up germination.

Germination: 5-14 days

Days To Maturity: Usually starts blooming in 2 to 3 months from seed

How & When To Harvest: Harvest blooms early in the morning for fresh cut flowers. Frequent harvesting and deadheading of spent flowers encourages more blooms. 

Common Diseases:  Sunflowers don't get too many diseases but in wet or humid environments can get powdery mildew or black spots. Improve airflow by proper plant spacing. Spray with 1 cup of hydrogen peroxide per gallon of water to clean and disinfect.    

Common Pests: Sunflowers don't have too many pests. Small critters like squirrels and birds like to eat the seeds from the flower heads.

Quality shelves. Easy to hang.
Color: Natural Wood
Hung them in my daughters room and she loves them. Easy to install but quality wood doesn't feel or look cheap. Will buy again for other rooms.

Eye pleasing shelves with the ability to hold weight
Color: Light Brown, Size: 4
Great set of 4 wood floating shelves. I used these to hold precon decks and other commander decks for magic the gathering cards. Though they are on the smaller size, they still fit up to 4 commander boxes side by side and and withhold double that if I stack the boxes. I am very impressed by the quality and how much weight each shelf can hold. The brackets to hang them make the shelves even more sturdy. The shelves are very pleasing on the eyes and the wood color is very natural. The shelves were simple to hang by one person. They look very stunning and of great value. They hold all kinds of items and function perfect as a shelf and look wonderful as a form/type of wall decoration even without items on the shelves. Overall I’m very happy with this purchase and I will be buying more of these shelves soon.

Great shelves
Color: Light Brown, Size: 4, Color: Light Brown, Size: 4
These are cute and easy to install. They were the perfect size for the location. I did use other drywall mounts to make sure they were more likely to stay in but after I installed they feel sturdy and reliable.
