hibiscus red eye

Morning guys I was lucky to pick up two sticky label plants for 50p each , they are in in 2litre pots and about 18inches tall about six stems .  I know it's not their season hence the price. Has anyone any ideas where's best to plant them I'm pretty open minded but will possibly keep them pruned because the only place I have for a large shrub/tree is under the Alder boundary or against next doors garage . I'm making a wide bed for smaller shrubs but it is north facing  .  Other beds are open in the middle of the garden with the exception of the front garden  which I'm hoping to make a tad formal  this faces SW .Sticky labels always give me problems  I've looked on web tips but they seem to prefer containers and I definitely don't need more of them  they do have a promiscurity problem  and increase in number in the blink of an eye
