not really unusual ... some of them you cant beat back with a stick.. if you wanted too ...

i dont understand if you are complaining ... if you dont want them.. remove now.. so you wont get more seed ... but even if you do.. you probably have a lot of old seed.. that will sprout for years ... if you dont apply a heavy layer of mulch to cover them ... most seed needs to be on the surface .. or very shallow.. covering in mulch defeats such ...

Your reseeding unwanted annual is melampodium paludosum, a.k/a butter daisy. Gardeners from Michigan, Ohio and Indiana have commented on other gardening sites that it reseeds for them too.

" You can see they're already way too big... " They look great to me.

Melampodium! One of my all time favorites. Always covered in cheery yellow blooms.

Nice to know about this plant! Looked it up and see it doesn't need much moisture and no deadheading, blooms from May to frost. Sounds like a dream plant.

It really is a dream plant. I have it in my beds right when you turn in to the driveway, where the hose doesn't reach. They only get water from rain and it can go a month without raining. Still they look great with neat plants covered with blooms. Will make these a must have for that spot.

Mine reseeded for about 10 years or so and then stopped about 5 years ago. May need fire them up again as they always look nice. No need to deadhead as they just grow above spent flowers.

my cosmos & zinnias reseed every year. Also have a blue heaven morning glory that reseeded & several tomato plants.

I get a few "volunteer" zinnias every year, occasionally an extra good one, but not nearly enough to count it as re-seeding.

Heavenly blue morning glories have become a weed here. I understand that morning glories are actually illegal in Arizona, due to their invasive proclivity.

My grandpa ott morning glory is becoming a nuisance as well. It climbs up and just cover the metal arch looking pretty, but it kinda smoother other plants in the bed, including the cannas and Italian sunflowers.

I've got the plain pinks and purple morning glories reseeding like crazy in the main garden. Fortunately, they're not hard to weed if you catch them early. Otherwise, they can be pretty climbing over things - until they start smothering and pulling plants down. Had thought some Heavenly Blues would be nice in the new patio garden, but am regretting it now, as they are doing just that. Breaks up the outlines of the other plants, making things look "messy". Next year I'll confine them to a little trellis tower all their own, and be ruthless with anyone who strays!

I'm of the group opinion, though, Carol. Yours look great just like they are! Prune them back if you feel you need to, but they look like they're "working" to me.
