I live just north of Satellite Beach, Florida. his critter grows right above the surf - with no tending. I have it in my yard, about 3/4 of a mile from the surf. It's nice BUT if you give it easy conditions it can take over the world - quickly. Blooms all year. Easy to grow. But be ready to do control!

Finally, now I know what's growing in my yard. This plant covers a multitude of brush and branches at the edge of our yard; very nicely. I never knew the name of this plant. It showed up all on its own and comes back after a freeze has killed it off. It blankets the brush and carpets the grass. Thank you for putting this up on your site. I live in SW Florida.

I would LOVE to have this plant, but I live in Southwest Virginia and doubt that it would survive the winters here(?) The temperature sometimes dips below 15 degress F. Does anyone know what plant I could get that is very similar to this one? I want a hardy and pretty groundcover that spreads relatively fast.

Grows very easily in South East Florida as a ground cover, left to its own natural wonderful-ness. It can replace thirsty water bills and reward you with affordable living any day. It is a native plant which does nothing but look super-wonderful all the time. it lloks great when its cold and when its hot. It does well in flooding rains as well. It propagates from seeds or from cuttings...

My only negative is that I planted it along my west facing sidewalk and some neighbors from who knows where , were liking it so much they would bend down and drag clumps home with them to plant in their yard.

I have found living in with these neighbors notso rewarding...and bad ambassadors to their culture.

Not great neighbors in north andrews oakland park but wonderful plant.

I now use it in the side and rear yeards...away from fisky hands...

I would like, so much, to have this plant. I planted it last year (obtained from Ace Hardware), it did not come back after, I guess, a horridly cold winter (in Florida, NE, go figure!) I don't know what I have to trade if anything worth while. My garden has not fared well this year -- the heat? Anyway, I sure would like a dune Sunflower or two and would be happy to trade four o'clock seeds (when they start producing, have loads of them!)

This plant has come up in a new bed, been in constant bloom and is quite beautiful. No spreading, possibly resulting from clay soil. Saw a picture today and knew this was my plant. No beach, no Florida, no sand. Zone 7 but 101 today.

I use this in designs frequently. Just be aware that it can be invasive.

We had this plant in our garden for a couple of years. If contained with no other plants, this is wonderful plant. If you have other plants, it will grow right over them unfortunately. But, it is fantastic ground cover.

We had some kind of webbing get all over it and it died. :-( Otherwise, I'd still be growing it. Little rays of sunshine every time I looked or went in my backyard. :-)

I purchased my Dune sunflower from a native plant dealer in N. Naples back in January. It's been in the yard ever since. I find it a vigorous grower in a "normal" (non beach) environment here in zone 10. My pictured plant has already been cut back around the perimeter three times since January. My plant is no higher than 12", but it has grown very wide. It's currently taking up about a 6' circle, after being cut back.
Bee's and larger butterflies like the plant for it's nectar.
This plant is a Florida native.

Beach Sunflower or Dune Sunflower is native to the coastal dunes, coastal scrub and open, sandy areas on the coasts of much of coastal Florida, from coastal Georgia southward on both coasts throughout coastal Florida and the Keys, westward along the Gulf coast into Texas. It is an excellent salt-tolerant groundcover with very nice flowers that provides pollinating sources for some insects. It is very valuable because of its importance of holding coastal dunes in place and stabalizing them, protecting the dune and holding it in place from strong storms. It is great for a wildlife garden in coastal locations, mostly from both 9a and 9b zones southward and is possibly easy to grow. I give this plant a thumbs-up!

MORE FACTS - Often grows with other salt-tolerant, dune-stabalizing native vegetation such as sea oats and railroad-vines, also called beach morning glories. Often grows in and loves open, exposed, sunny locations. Drought-tolerant and adaptable in the landscape. It is a superb groundcover near sidewalks and pathways.
