Not to mention those itchy hairs in the middle that make removing the seeds unpleasant. (Ground-up hairs from the center of rose hips are the only ingredient in itching powder!) Do you know of any tasty species that lack those? If so, that would be a good species to start breeding with.
Obviously thornlessness would be hugely appreciated, too. Rose thorns can be particularly nasty.
Those are beautiful mallow flowers!!! On my mallow the seed pods are easy to find but the flowers are usually tiny. I bought seeds from Baker Creek hoping they will cross.
My mallow doesn’t try to take over as much as something like bind weed or grass and its easy to pull up. Wonderful to have something easy to grow when everything I planted is struggling.
Yeah, common mallow is a great weed! It’s a pleasant groundcover that is no problem to step on, nice to eat, and quite drought tolerant.
Bindweed is pretty, but it can be such a pest. And as for goatheads, which like growing as weeds in my neighborhood . . . 
One of the great things about finding weeds you like is that you can collect seeds from them and sprinkle those around wherever you’ve just pulled out a weed you don’t like. It’s a delightful way to keep the soil covered with species you’re happy to have growing nearby.
Did I mention that I found a creeping bellfower under a neighbor’s rosebush this year? She didn’t care about it, so I got to eat half of the flowers and leaves, and I left the rest to make seeds for me to save. The flowers were delicious, and the leaves were nice, too. I’m gonna sprinkle those seeds around in lots of places and hope they turn into invasive perennial weeds for me too, hee hee hee.
Yes I’m very familiar with goatheads unfortunately! Very difficult to find something to love about those!!!
I personally think goathead flowers are quite pretty, even though they’re small. A nice splash of pink color, too. Unfortunately, then they turn into some of the worst caltrops that nature has to offer . . . 
Extreme drought tolerance is a wonderful trait in general, too. I just don’t want it in plants that grow caltrops. 
yes to the power of positive thinking!
