Last time I briefly discussed the Thriller, Filler and Spiller concept of garden design and how I plan to use this basic technique to pre-design some spaces for whatever new garden I may have in the future. I am expecting to have a garden space very typical of today’s smaller gardens. By pre-designing some garden spaces, I will be able to mix and match as needed when I do find my new place. Being a gardening addict, and I need to stay hooked up any way I can!
I chose Picea omorika ‘Gotelli’s Weeping’ as my Thriller plant for this first space. I love its tall, majestic form, its sweeping, weeping branches and its shimmering bluish green foliage. This time I will discuss a few candidates to use as fillers in the imaginary garden space. One thing is for sure, I will be using a Red Japanese Maple as a filler with this tree. Whether I choose a weeping type with finely dissected leaves or a more tree-like form with broader leaves, I will love space being filled with red foliage as a very nice complement to the color of ‘Gotelli’s Weeping’ plus, being deciduous, it will open up the space during the winter for a different view altogether. Choosing just the right cultivar may be the greatest challenge so far.
There are several factors that I will consider about the space when I do make my final decision and plant the trees. The size of the space will play a big role in determining which cultivar will be the best fit. I will also need to consider the existing light and how it might change over time with nearby trees already in place or on neighboring property.
If I have the space for a larger tree then Acer palmatum ‘Bloodgood’ is at the top of my list. It is an old standard these days and is hard to beat for fantastic, rich, dark purple/red color that lasts all season long. During the winter, when the leaves have been shed, its dark purple branches add interest to the colder landscape.
Another favorite red foliage specimen is Acer palmatum ‘Twombly’s Red Sentinel’. This very well-mannered, small tree has a unique, compact habit that grows into a very nice oval shaped form. Like ‘Bloodgood’ its rich red foliage lasts all season. In autumn the red brightens to an intense scarlet. I may choose this one if space is somewhat limited.
If the space is a little shady, I may choose the uniquely colored Acer palmatum ‘Ukigumo’. With near white, pink and green variegated leaves it could be a Thriller itself. The softer color will complement the foliage of the Thriller nicely and will add a lot of interest because of its unusual variegation. Any shade it receives will help protect its more delicate foliage from sunburn during the summer.
One more Filler possibility should be a thrill for my friends in the colder regions. Acer x pseudosieboldianum North Wind® is an extremely hardy hybrid of Japanese and Korean maples that has been proven to thrive in some pretty nasty Zone 4 conditions! Fortunately for me, we do not get anywhere near that cold where I live, but this selection is more than just a tough guy, it’s gorgeous too! Soft reddish orange spring foliage turns green through the summer. Colorful red seed clusters and intense red and orange autumn foliage make for a long and exciting season of color and interest.
As I have been writing my thoughts, I have come to realize that there is no reason why I couldn’t choose both an upright tree form and a weeping lace-leaf form to use in this space. In fact, I suspect by the time I begin to consider plants for the Spillers, a nice lace-leaf Japanese maple will make it on the list. For now, I will need to contemplate other filler plants to use with the above maples in each of their unique, possible situations.
