Whereabouts are you in the country and what is the cardinal orientation of your garden?
If you are in a sheltered area and you get a lot of sun, you could easily create a tropical garden that will have a real wow factor. Think hardy palms, bananas, cannas, ferns, colocasia, and climbing plants like star jasmine, morning glories, passion flower and clematis. Then once the structure is in place, add flowers like dahlias, crocosmia, trycirtis, hedychiums, or anything really - I also have lots of salvias, verbena bonariensis, nicotianas, zinnias and they all blend together.
I started my tropical style garden in spring 2023 and it has totally come into its own this year. We also entertain a lot and I get lots of compliments (and questions!) about it.
You can look for inspiration on YouTube, the channels of George’s Jungle Garden (he’s in Lincolnshire), Yorkshire Kris and Craig from Grow Paradise are all informative (though George waffles on a bit - but I’ve learned a lot from him). Or come over to the MN jungle garden thread, we’re very friendly ☺️🌴
