The flowers on plants grown from seeds from a hybrid won't be exactly like those of parent plants. This is not to say they won't be pretty blooms. They just might be somewhat different. For those who've never sown sunflowers, plant the seeds about an inch deep in a sunny spot. While sunflowers aren't that picky about soil, a moderately fertile, well-draining loam is ideal.
Germination occurs within two weeks.
I've had seedlings pop up in as few as four days. Thin the seedlings if necessary. Don't let the plants dry out. Bloom time depends on the variety, but can be within 55 to 60 days. My question concerns hollyhocks planted three summers ago.
