| So you have part sun / part shade, but open to the sky - that's good - sandy soil - pretty easy to work with. There are hundreds of plants that could fit the bill, holly alone comes in many forms. I like to mix evergreens for an informal hedge. It is nice to have color contrasts & different flowers &/or fruit IMHO. Given your site I am tempted to say plant camellias and michelias. They are not the most forgiving plants, but the payoff is fantastic - lush evergreens with flowers that will blow your mind. Michelias are kin to magnolias, but most are more compact & smell great. Upright holly is about as easy as it gets, and you can mix leaf color, size, & shape, even berries - most are red, but some are yellow or black. Osmanthus - false holly & tea olive - are all cool. Osmanthus heterophyllus 'Goshiki' - a bright variegated version is a standout. Speaking of variegated, Aucuba japonica is a good one for shade areas. Mahonia bealei also likes shade, and has a unique look. Ternstroemia gymnanthera - Cleyera is a nice well-behaved evergreen, new leaves are a deep glossy red, then turn dark green. You should have Illicium parviflorum - Anise shrub. Chindo Viburnum - magic. Evergreen Azaleas - just pick a color. Podocarpus macrophyllus - another unique, upright evergreen. Pittosporum tobira - variegated or solid green, common, but they smell great & no fuss. These are just some ideas for a starting point. You could add some smaller plants under / between these, mix in some other flowering shrubs or deciduous trees for contrast, groundcovers, flower beds in front, etc, etc... It may take a while to find what you want & get it together, but it is SO worth it when it clicks. Please don't rush out and plant some ho-hum Home Depot junk. Hold out for interesting, quality plants & you'll be glad in the long run. Think of something new in bloom each week, birds in the bushes, etc. Way better than a straight bland hedge. Just my 2 ¢ Oh, lastly, you may want a soil test before you plant anything. One of the harshest mistakes is killing expensive plants in poor soil that could have been fixed with a few bags of something, or using the wrong plants for a site. My guess is your lot is fine, but better to make sure. |
