Last time I focused on some of my favorite broad-leaved foliage Fillers. As you may recall, I am pre-planning some ideas for a new garden space without actually having that space. A couple of posts back I chose a great Thriller plant to work with in this potential design and then I added to the plan a few different colors and forms of Japanese maple that I think will fill in nicely with their multi-seasons of colorful foliage. But, I certainly cannot fill the space with broadleaves alone – I also need to add an assortment of colorful and interesting dwarf conifers. This time I will mention some plants that I think will work well together based on their sizes, shapes and their growth rates.
Beginning with a large, silvery, bluish-green Thriller specimen (Picea omorika ‘Gotelli Weeping’) and then adding a deep red Filler (Acer palmatum ‘Twombly’s Red Sentinel’) I can continue to fill space with some very nice color and texture. One plant that will add both a unique texture and a pleasing green color is Thuja plicata ‘Whipcord’. This very popular dwarf conifer will slowly fill space with its coarse cords of light green foliage. Growing into a mounding form with branches which arch upward, out and droop toward the ground creates a very nice complement to the upward growing branches and red foliage of the ‘Twombly’s Red Sentinel’. It will also make a nice background plant to smaller fill-plants and other dwarf and miniatures that I will discuss later.
The next two dwarf conifers that I want to consider for my imaginary space, yet-to-be are Chamaecyparis obtusa ‘Nana Lutea’ and Thuja occidentalis ‘Golden Globe’. Although both are plants with yellow foliage, they are quite different shades of yellow and each has its own unique foliage and growth habit. ‘Nana Lutea’ is the classic Dwarf Golden Hinoki and had been very popularly used in gardens for the past 50 years. It grows very slowly into a pyramidal shape with tightly held sprays of golden yellow foliage that become more intensely colored with increased hours of sunlight. It may need some protection from the hot afternoon sun in some locations to prevent its near white portions of foliage from scalding. A mix of sun and shade should provide beautiful color.
‘Golden Globe’ on the other hand, is a more vigorous grower with more muted yellow tones. It responds very well to light shearing, and I prefer to keep mine in a neat globe shape by running the shears over the new foliage once per year. This practice not only helps keep the plant in tip-top form, but releases its magnificent perfume and makes shearing less a task and more of a real pleasure. Depending on the overall space, I may use one or both of these in my future design.
Ahhh… my imaginary new garden space is beginning to fill in nicely. Be sure to come back next time for more of my dreamy Fillers!
