I'm new to gardening and completely clueless have bought some plants I like but no idea how to arrange or space them have attached pics of border and plants to help. Any advice is much appreciated.

First, we have to know where you live and what exposure (faces south, east, west, north?) this garden has. Are you taking up the lawn? How many hours a day of sunshine does this spot get. How cold does your climate get? How hot?

You have Hibiscus which takes full sun and a lot of water. What does the name on the tag say (Tropical Hibiscus, Rose of Sharon)? What tempurature does the tag say its hardy to?

The other two are Dusty Miller and Dianthus. Do they have labels?

The labels in the pots should help you with temp. range, sun/shade requirements and suggested spacing. We can help you decipher and decide what to do.

I see from the dustbin that you're in Staffordshire, UK. Are you planting these in the whole L-shaped bed? There don't seem to be a lot of plants for the whole thing, but you could plant the ones on the blue dustbin in groups at about 9" inch spacing within the group if you're growing them as annuals, although they may be perennial in your climate. I know the silver one is perennial there (used to be called Senecio cineraria but that might have changed - I don't recall the common name in the UK being dusty miller like it is in North America). If you're planting it as a perennial the spacing should be wider. Does the pink-flowered individual plant have a label? It does look like a hibiscus/mallow/lavatera....
