On the left is my tuberosus x annuus perennial sunflower seedling [Jerusalem Artichoke x 'Red Sun' sunflower]. It's been blooming since late June. See post on July 7th. On the right is its seed parent - Jerusalem Artichoke - still not even showing any flower buds yet. I was hoping I'd get red petals in the seedling, but I won't complain about this long season of bloom!I've also noticed that this year it's making quite a few fasciated flower heads - another sign of its annuus ancestry. Two are pictured close up below.
