Last fall I ordered seeds for a pink sunflower - Midnight Oil - and coveted them throughout the winter for spring planting. They weren't cheap: 15 seeds were offered for $11.99 on Amazon (that's nearly $0.80 per seed!)
It was probably April when the weather began to warm enough that I planted the seeds in potting soil and in peat pots on our enclosed south-facing porch.
I moved them to the north end of the garden in mid-May when the risk of frost was past.
Recently I noticed the plants were beginning to form buds. They were still short - dwarf sunflowers that were no more than a yard tall. That was my first disappointment. But then the buds began to show color.
Yellow!
