Agree with manure and Bob's thoughts about alkalinity. It does seem likely that acid lovers will not be suitable there
i would plant annuals for this year...after manuring...and use the summer for sketching and researching what plants you would like there. Try to get shapes......spikey plants as well as mounded .....foliage colours and some evergreens for structure. Not forgetting height too of herbaceous plants. An opportunity to get to "know" your plot and see how things grow.
Ex lawns often contain soil pests during their first year of planting so annuals are expendable enough this summer.
aim for early autumn planting of major shrubs
