1. Official seeds only. Only sunflowers grown from the special Nalls seed pack are eligible to enter.
2. One entry per person. Must be grown outdoors in soil (greenhouse or hydroponic entries are not eligible).
3. How to measure. Measure from the ground to the very top of the flower head using a tape measure or yard stick.
4. Photo requirements. Your photo must include: you, the tape measure, your sunflower, and something Nalls-branded (this seed packet works or when we get closer to the deadline, pick up your official entry sign).
