This past Labor Day holiday weekend, my wife and I enjoyed visiting one of our favorite independent garden centers across town. Although our goal for the day was to find a few new house plants, we had a tremendous time strolling through the entire nursery, and I found some fantastic miniature and dwarf conifers to include in this segment of my ongoing series of Thriller, Filler and Spiller garden design.
As you know, over the past several posts I have been discussing my plans to create a great new garden space with a colorful assortment of conifers and other exciting garden plants. I began with a specific Thriller in mind and have been imagining what other plants I will use to fill space around it.
Be sure to check out those past posts if you have not been following along. Today, I’ll be talking about some of my favorite slower growing dwarf and miniature conifers for filling in more detailed smaller spaces.
Once I have the larger plants in place, I like to get down and dirty as I create small, intimate spaces, filling in with very slow growing plants and other details like interesting rocks or other garden ornaments such as bird baths, etc. I am talking about plants today whose annual growth will be limited to less than an inch or two per year in my Pacific Northwest climate. I love these plants because they have so many great features. My favorites offer slow growth, interesting texture, unique form, great color and sturdy performance.
An all-time favorite, and perhaps one of the larger selections on today’s list is Picea pungens ‘St. Mary’s Broom’, which I chose because of its reliable, light blue color and slow growth. Rated at USDA Zone 2, it is far more winter hardy than I require in my climate, but with well-drained soil and a sunny location, it will perform very well and provide a solid blue color statement on a small scale in the garden.
For a good dark green and unique texture, I’ll include Picea abies ‘Mikulasovice’. This dark green, mounding plant displays needles of a longer length than one might imagine on such a small, slow growing plant empowering it to add a unique texture to the garden. Another good, dark green plant is so slow growing, it might be confused with being a moss covered rock, in fact that is what inspired its name of Chamaecyparis obtusa ‘Greenstone’. The tiny, fine textured foliage covers this small, rounded mound which is perfect in miniature container gardens as well as a small detail in the larger garden as I am including today.
Picea orientalis ‘Tom Thumb’ is a delightful golden yellow miniature conifer with tiny needles covering the small branches which form this slowly spreading, mounding plant. Speaking of bright yellow, I will have to include a Chamaecyparis obtusa ‘Butter Ball’ to this list with its soft textured, lovely golden yellow foliage and slowly mounding and eventual broadly conical habit.
I find with all of the above broadly mounding, and spreading forms I will need to include a few more upright and narrow forms to break up the monotony and add more visual interest to the smaller details of this garden space. One of the first to come to mind is a very fine textured, narrow, compact form of the Dwarf Alberta Spruce called Picea glauca ‘Jean’s Dilly’® This rich, grass-green plant grows very slowly into a narrow, cone shape and will remain in perfect scale with the other miniatures on today’s list. Of course I must include one of my very favorite plants, Picea glauca ‘Pixie Dust’ at this time since it fits the specifications perfectly and adds a bright twinkle of color.
This list could go on and on, depending on how much space I end up with. Next time I will finalize this series with a list of some favorite Spillers which will spill along the ground, filling in and covering open space with year round color!
