How long do flowers take to grow from seed?
The seed packet should tell you how many days to bloom, which means how long it takes from germination to flowering. If you have a short growing season and the packet says it will be 80 or 90 days to bloom, you will need to start the seeds indoors if you want to see them flower for a couple weeks before frost. Garden experts agree that calendula is the undisputed champion of fast-growing flowers. Germination occurs just five to 10 days after planting, and blooms appear within six to eight weeks.
What is the easiest flower to grow from a seed?
Zinnia flowers are one of the easiest plants grow, grow quickly, and bloom heavily. They make a massive burst of color in your garden, and they attract butterflies. Zinnias are annuals, so they grow for one season and make great cutting flowers. Sunflowers, zinnias, nasturtiums, and spider flowers are all fastest growing plant flowers that bloom quickly from seed.
