Perennial Sunflower
Whatever variety, these sunflowers are invasive. They’re sneaky and prolific with an underground network always working to expand the sunflower’s domain. These sunflowers can overwhelm a flower bed when new plants are allowed to spread. Constant vigilance is needed and harsh yoinking of trespassers necessary.
These are a variety I bought and while they’re not as invasive as Jerusalem Artichokes they’re close. I’m using them as a background but they keep insisting on a place up front and everywhere in between.
I don’t really think these are any more ‘work’ than other perennials, after all the bed needs to be kept weeded anyway. Besides a little work is worth the effort in order to have these bright yellow flowers the bees enjoy so much.

Another visitor to the sunflower today was this hover-fly. I’m not going to try identifing either of these flower lovers. I made desktop wallpaper instead.

My time on Long Island is about up. Figures the heat and humidity has finally let up after 11 days of me doing a pretty good job of impersonating a puddle. The only good thing of having to change my sleeping habits and getting up at 4:30 in the morning in order to beat the heat will be the early head start I get in the rat race tomorrow morning. I should be home for lunch

We have one of those! If it’s the same, it’s Helianthus helianthoides, and boy, does it spread! I’m planning to dig up and divide our next spring, because it’s overwhelming the spot it’s in. It can ramble at will on the other end of the bed. I learned that cutting it back in June by nearly half keeps it from flopping over–worked really well in this wet wet year. Enjoy getting out of the heat!

Fast spreading can be good or bad, depending on the area one has to fill.
