Generally start seeds 6 to 8 weeks before the last frost. The seed packet will tell more.
Hollyhocks and sunflower grow easily from seed planted directly outside. You can plant hollyhock seeds one week before the last frost. Sunflowers you can plant after the last frost.
Gladiola corms are planted directly in the soil beginning in spring. You can buy those online or in garden centers.
