Planting scheme?
Hello folks
With my apologies for the rudimentary drawing, I have this space in a newly-designed garden:

At the 'top' of the diagram is a patio which is overlooked, the whale-shaped blue is a cascade and pond. The 'bottom' of the diagram is lawn.
In order to screen the patio from particular windows, I've bought 3x calamagrostis and 3x molinea. Aside from that, I've bought 1x dryopteris (which I had in mind for next to, and overhanging, the cascade), 1x rodgersia, 3x rudbeckia little goldstar, 2x allium purple sensation. My questions are, if you'd be so kind:
1. Can the calamagrostis and molinea be interplanted or am I better off planting them, say, with the calamagrostis on the 4.5m length and molinea on the 2.5m length?
2. Between rudbeckia, verbena and allium, which would you recommend for planting with each of the grasses, or could I, say, plant allium with either grass? If so, I'd be inclined to put verbena in amongst all the grasses to give some continuity between the two beds (the black circle which separates them is the pond filter).
3. Where would you place the rodgersia and the dryopteris to look good with the grasses? I was going to plant both near the top of the 'whale's tail', one on either side to frame the cascade with greenery. What do you think?
Thanks for any help. This is really my first garden!

Rodgersia likes moist soil, so should be near water.
When you don't even know who's in the team
S.Yorkshire/Derbyshire border
The pond filter currently has a rock cover over it, 'though that may go as I think it makes more of an eyesore of it than without.
The molinia is Windspiel.
As the greatest need for the screening is in a line between the furniture and the sedges, I'll probably put the calamagrostis there if it's more reliably upright and then put the molinia in the smaller 2.5m gap where it isn't such an acute need for screening from next door. There is plenty of moisture because that bed gets the run off from the patio.
@B3, thank you. It was my project for pretty much all last year. It's getting to be quite different from what I inherited when we bought the house...
Alliums if soil is wet I would put a layer of grit in the planting hole.
Rogersia you will need to water this if conditions are dry
Rudbeckia will be fine in a retentive soil.
Dryoptreis is not a plant you I would normally grow with grasses they have very different natural growing conditions but I understand why you have bought this.
Verbena bonariensis? like all verbenas need good drainage if they are happy you will have lots of seedlings, plant with some grit.
Gardening is a matter of trial and error everyone gets stuff wrong and other things make you happy .You have a mix of plants which will tell you all you need to know about the environment and soil they are growing in. Don't plant into soil that is frozen or waterlogged.
