I use artemesia Powis Castle as a foil for bulbs and other taller plants here in Zone 7. The aretmesia forms a nice 6-7 inch tall, lacey grey ground cover that lets the bulbs grow through. And it's evergreen (grey-green actually) here in zone7. Currently in bloom are some very light, almost white daffodils poking their heads over the gray lace of the atemesia. Later there will be various lillies and the datura will eventually wake up too. I have to re-plant moonflowers every year, and I usually put them near the back where they can mix-it-up with a honeysuckle I have growing on my back wall. I use a mix of lillies so there's almost always some in bloom from spring to fall. They're also good flowers to use for dedication gardens as they symbolize purity and innocence, and the restored innocence of the soul at death. Best wishes

To me a moon garden would consist of white, fragrant, plants like Moonflower (impomea) vine, the fragrant nicotiana, maybe some grasses if you have lots of space like gayfeather, abelia, and so on. I don't have a lot of space so I mostly stick to the moonflower vine with its heavenly scent (blooms late in day and stays till morning) bacopia which spreads nicely and is problem-free.

Hi HW, you said it: It is difficult to choose just one. If I may choose just one from different categories, ha ha ha..always trying to stretch it. spring bulbs: Calgary Tulips..large flowered, low to the ground and heavy substance, lasts a long time. Shrub: dwarf Minnisota Snowflake Mock Orange..long bloomtime, covered with double white extremely fragrant white flowers. Summer bulbs: it would have to be any of the lilies, candidum, trumpet, asiatic, species, turks cap, Oriental, formanosanum. They all last a good while and most are very fragrant too. The large flowers make a good impact. perennial is really tough...I'm probably going to say Carolina Phlox Miss Lingard...early and long blooming, fragrant. vine: tough again, but I'd have to say moonflower. annuals..ha ha ha..too tough to pick just one. Really, so for this post I'll say zinna white profusion.. but there really are so many that I wouldn't do without. I can't seem to find plumbago here locally. I know it isn't hardy here, but I'd still like to try it. I don't have much of a shock value white, maybe the Blue River II Hibiscus, for sheer flower size. Same is true of the dinner plate white dahlias. Thanks for the post, it makes me realize, I don't have an absolute favorite..way too many..peonies, iris, lilac, yikes, I feel guilty not mentioning half of the garden..ha ha ha...enjoy...JoAnn

Well I don't know much about Wales, but here in Columbus, Ohio, my east facing garden with a house right next door does very well. Basically, it's a garden designed for night interests, plants that are white or deep purple, night blooming plants, night scented plants. Tell us more about Wales and the conditions you face. That would help a bit.
