Maybe an odd request. I'm new to gardening. I'd like to put in a flower garden in a sunny area of my yard. I have an assortment of seeds and plants. I drew out a design so I can visualize where everything will go. Would this work? So you see any red flags? The sizing should account for full grown spacing needs. Thanks!

Flowers/seeds I have-

Golden yarrow

Zinnia (annual)

Maltese Cross

Red Yarrow

Blacked Eyed Susan's

Gloriosa Daisies

Walker's Low Catmint (plant)

Yellow reflowering daylilies (12-24" tall) (plant)
