Sunflowers are an annual plant native to the Americas and today, many heirloom and hybrid varieties are available.
According to the online catalogue at Seeds of Change – a certified organic seed supplier in the US (and my source for Tiger's Eye) – "This mix offers a rare selection of intriguing sunflowers with bronze, gold, and maroon double-petaled centers with single petaled outer rays, and an occasional fully single or fully double individual."
These open pollinated plants are definitely easy to grow in a full sun location. They are best direct sown in a garden bed in early spring and germinate in 7-14 days. A plant spacing of 12-18 inches is recommended. I planted them at the back of a new potager bed in a very fine bark mulch. They found their way through to the light without trouble and the mulch kept them moderately moist, as recommended.
I have tried to discover the specific sunflower types that may be included in the Seeds of Change Tiger's Eye mix, without luck. The flowers ranged from bronze and red to brown and yellow; many were multicolored with a distinctive "eye", which gives them their name.
Photos tell the story best ...
Another discovery? The heads consist of many individual flowers which mature into seeds, often in the hundreds. The complex structure makes them interesting to photograph.
