This comparison, I can do it! It was completely unintentional at first, it is not in the kitchen garden but whatever, the comparison can be made.
There are 3 years I planted a hundred iris. I first put eighty along a wall, in a soil that was sifted to a thickness of about 40 cm. The rest on a mound where the earth has not been sifted but simply cleared of the largest pebbles.
I put a handful of compost at the planting of each rhizome.
Photo of the irises planted along the wall in a thickness of 40 cm of sieved earth:
Iris in sieved earth.
Photo of the irises planted on the mound of "raw" earth, soil which is already better than the original soil:

The smartphone gives the scale.
Irises planted in the mound of raw earth never bloomed. They are 3 at 4 times less high.
There's no picture ... To each his way of doing things.
the same but upside down ...
I planted lavender in dry, stony soil and it's like a charm ...
I planted it in peat and it vegetates ...
The same at the place?
I planted ferns in a dry and stony ground and she vegetates
I planted it in moorland and its fronds are beautiful ...
The irises love the light earth and even worse it develops almost on nothing, I recovered in species of carpet of grass and leaves with a layer of symbolic earth and they were giant ...
In short if you put them in the right place they will develop better than if you put them in a less favorable place It makes sense
Just below the house there is a big mound of stone with a few cm of soil filled with iris ... these are not the most fantastic ones I've seen but there are nevertheless dozens of them develop in the state ... say wild since they are nobody (photo to come)
Many things can grow in clay with pebbles and without tillage.
I've often illustrated salads that grow in hard-foot like concrete.
In short the pebbles have been removed, now only to put them back to improve the drainage and decompaction of the clay .... I'm joking.
