Yes - some plants might Posy - but a small, young plant shoved into a border at the wrong time of year, will sit and sulk - or even just rot - and will be vulnerable to attacks from pests, particularly slugs and snails. A plant that's allowed to mature gradually tends to shrug that off more easily.
In nature, a seedling/plant which grows from something seeding around, will mature slowly according to it's conditions and the time of year, which isn't the same as one we would raise in a more cossetted environment .
You have to choose carefully which plants you can put out early on, and the soil conditions and temperatures are a major factor.
