Sleeper flowerbed evergreen plants

Hi, I had just had a flowerbed made out of sleepers at the front of my house and is under my living room window. I am looking to plant evergreen plants to make it look modern, what evergreen plants and which positions to plant them? Thanks in advance

 

Hi Caroline, it would be helpful to know how big the bed is (length, width and depth) and whether it is in sun or shade. Also what part of the country you live in - only need a rough idea.

 

As @Escarpment says, we'd need more info so that suggestions are viable @Caroline Pruden. There are huge variations in conditions around the country, and the aspect of the bed is particularly important
Also - what time do you have for maintenance - some plants are quite easy, but others need more work, and how much room is there between the bed and the window? I'd assume you don't want planting covering the window too much.

 

Also, it would be helpful to know what type of soil you have @Caroline Pruden, for example typical loam (easy to dig and retains moisture), dry sandy soil or clay.

 

Hi, thank you all for your responses, I have attached a picture, the soil is top soil. Thanks

 

Is it open at the bottom? What's underneath?

 

Did you fill it with soil yourself @Caroline Pruden? Top soil doesn't describe the make up or structure of the soil itself - it just means it isn't subsoil, which isn't suitable for growing plants.

We still need the other info requested or else we're just guessing, which is also no use to you. You could end up with plants that don't thrive - or even survive.

 

Hi, it is just ground soil underneath. Thanks

 

My Gardener brought the soil in bulk from garden centre

 

Yes open at the top and ground soil underneath. Thanks

 

We still need the other info @Caroline Pruden - aspect, rough location etc.
For example, I could suggest something like Acers, Camassias and Acteas, but if it's a south facing site and you're in the south east of England, those would never be happy, because they need moisture retentive soil and reasonable shade from searing mid day sun. Up here, they can manage more sun, but that's because it isn't as hot here, and we get fewer hours of sun anyway. A cooler, cloudier climate means soil doesn't dry out so quickly, which makes it easier to grow that sort of plant/shrub. Equally, if it's a north facing site, and if it's getting very little sun in summer, and you're in Sutherland, Salvias and other sun lovers would struggle. The house wall can also mean rain doesn't get in easily, so a bed under a window can be much drier than one in a more open site.
Cold, frosty/icy snowy locations in the north will also mean many plants simply won't survive, although it's long term wet cold that causes most problems.
