Gnarly giant sunflower seeds are selected for gardeners interested in large stalks and flower heads. Each packet contains five seeds from the family’s Gnarly parent sunflower, with germination, growing and feeding tips included. The parent plant’s measurements describe its history and do not guarantee the size of future plants.
Gnarly’s recorded parent-plant measurements
The parent sunflower stood over 16 feet tall. Its flower head measured 23 inches across, and its stalk measured 10.5 inches in circumference. Those recorded details distinguish Gnarly from the sunflower packets identified primarily by the height of their mother plants.
