No. Sunflowers are not perennials, they are annuals. You need to plant them every year.

No--if it's the regular annual sunflower.
Yes--if it's a perennial sunflower such as a Jerusalem artichoke.
They are actually a true sunflower (genus Helianthus) that has underground tubers. The "regular" annual sunflower is Helianthus annus, Jerusalem artichoke is Helianthus tuberosus. The tubers are also edible. The plant can be invasive.

Here's a painting by Monet "Jerusalem Artichoke Flowers"

Other perennial sunflowers that are cultivated include: Helianthus angustifolius, H. atrorubens, H. maximilianii, H. multiflorus and H. salicifolius. I believe none of these are tuberous. Source: Sunset National Garden Book.

Sunflowers are an annual. they could desire to be planted from seed each 3 hundred and sixty 5 days. save the seeds from the flower head. Dry them, then peel them off and save in a cool dry place. the outcomes would be a similar because of the fact the unique plant.

The only way it will come up next year is if some of the seeds from the flower drop off . Pull off the flower head when it is done blooming and dry them out for seeds next year. Plant them mid spring.

No you have to plant them Avery year. the only way it would grow again is if some of the seed from the plant fell off and started growing

sunflowers are annuals so no they won't come back next year, but they self sow easily so most likely some more will grow next year.

Only if it reseeds itself. Otherwise you will have to do it yourself every year...It's considered an annual not a perennial
