My sunflowers have yet to grow up—the seeds I planted in April were promptly picked off by birds, and I waited too long in vain for them to make an appearance before replanting (deeper this time!). They’re still just babies at this point. But my next door neighbors planted a whole row of seeds a couple months ago, and they’ve been steadily reaching skyward this whole time. In the last couple of days, first pair opened up, right across from my own back door. Thanks, neighbor.
