Tasty dwarfs to fill some space

As I continue to explore ideas for designing a new garden space, I am looking at some of my favorite plants to use as Fillers – plants that will fill the space with year-round color, texture and interesting form. Last time I chose three dwarf conifers which might be considered fast growing as they will tend to grow larger in a 10-20 year span of time than the selections I will explore today.

‘Banderica’ is a neat, tidy, slow growing little kiss of a conifer that will add a dandy flavor to the conifer garden.

I began this design project with a great Thriller tree, then I selected a few Japanese Maple Filler plants to pick from depending on how large (or small) my actual future space may be. My next decision was to choose a few larger dwarf conifers that will scale nicely with the maples. Based on those choices, I am ready to scale down the expected size of this next group of dwarf conifers.

This time I will take a look at a few green colored choices, each with its own distinct shade of green and unique textural features. I’ll also include a dwarf blue and a dwarf yellow selection to spice up the color palette a bit.

‘Sea Urchin’ has soft, light green foliage (with a hint of blue) and fills in a small space with other dwarf conifers and other exciting plants.

I love the rich, very dark green color of Pinus leucodermis (heldreichi) ‘Banderica’ which, along with its perfect, slow growing, broadly conical form makes it an excellent, formal looking small tree. Pinus strobus ‘Sea Urchin’ adds a pleasing effect as its rounded, slow growing, soft textured form highlights its bright, light green hues. Picea abies ‘Hildburghausen’ begins the spring season with a flush of bright  green foliage which matures into the medium green color we enjoy most of the year. Its unique mounding, textural form stays neat in the garden while slowly filling in space and looks great with an artfully placed rock nearby.

‘Hildburghausen’ is a sculptural, low, mounding dwarf conifer that fills in space with reliable color and a pleasing form.

One of the slower growers in today’s selection may also have claim to the most interesting color of the group. Chamaecyparis pisifera ‘Blue Moon’ has very soft foliage with responds well to a light trimming should one be inclined to encourage its globe shape. The color of this cultivar is more of a steel blue than other common selections of Sawara Cypress such as ‘Boulevard’, ‘Curly Tops’ or ‘True Blue’. It is also a slower grower than the others which helps it remain a great garden filler plant for many, many years.

‘Blue Moon’ is a delightful, globe shaped, soft textured, steel blue conifer that will provide a dandy color spot where there is a small space to fill.

Finally, I just have to include a Cryptomeria japonica ‘Twinkle Toes’ to this group for its reliably compact growth, its coarsely textured, bright yellow foliage and its informal, mounding, broadly pyramidal form. Plus, I just love to tell folks that I love my ‘Twinkle Toes’ and if they visit my garden, they’ll fall in love too!

The coarse textured, bright yellow foliage of ‘Twinkle Toes’ adds a touch of Zing to the garden!

My imagined garden space is beginning to fill in nicely! I have a few very slow growing dwarf to miniature conifers to add to the list which will complete the Fillers, and then I’ll post some definite selections to choose from for my Spillers, which will be very low growing to prostrate forms that crawl along the ground and fill space between larger plants.

Until next time…

Filling up space with great color, texture and form

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 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.

Thuja plicata ‘Whipcord’ adds good color and a lot of great texture to fill garden space.

Beginning with a large, silvery, bluish-green Thriller specimen (Picea omorika ‘Gotelli’s 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.

Chamaecyparis obtusa ‘Nana Lutea’ is a slow-growing filler that adds a thrill of its own with its great color and superbly graceful form.

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.

Thuja occidentalis ‘Golden Globe’ is a filler with pleasing form, bright color and a lovely scent.

‘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!

Filling with foliage

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.

Richly colored foliage persists all season long on this popular Japanese Maple, Acer palmatum ‘Bloodgood’.

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.

One of the most popular red Japanese maples, ‘Bloodgood’ provides great color and fills in space very nicely.

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.

This deep red filler keeps itself in nice form with its compact, oval shape.

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.

Beautiful, softly colored leaves of Acer palmatum ‘Ukigumo’ can fill your space with floating clouds of foliage.

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.

The North Wind® Maple is a very hardy choice and a great looking tree!

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.

The autumn foliage of North Wind® is worth waiting for each year!

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.

Stay tuned!

Weeping welcomed here

A few posts back I mentioned that I would be sharing some of my ideas for conifer groupings in my future garden. One of the primary features of any plant grouping is the “focal point.” This concept applies to large garden vistas, smaller viewing spaces and all the way down to container gardens. You have probably heard someone use the phrase, “thriller, filler and spiller” when talking about container garden design, and the same basic concept applies to the full-sized garden. Each of the plant groupings that I will share will incorporate this basic design concept in one way or another.

Picea omorika ‘Gotelli Weeping’ – This specimen “thriller” is a brilliant focal point in the garden.

One of my favorite larger “thriller” plants is a beautiful form of the Serbian Spruce. This cultivar was admired many years ago growing in the National Arboretum with the name, Picea omorika ‘Pendula’ and was propagated and sold for many years with that name. In 1979 a respected conifer enthusiast and grower gave it a distinct cultivar name because it appeared to have unique characteristics and it was believed to be important to keep clones of this distinct tree separate from the assorted other pendulous forms that had been marketed under the name ‘Pendula’. Unfortunately, it has taken many years for that name change to take place throughout the world of conifers (including conifer growers) so this magnificent cultivar may still be found in US garden centers under the name P.o. ‘Pendula’.

‘Gotelli Weeping’ is a large tree pushing out a foot or two of new leader growth per year, depending on its cultural conditions. The young graft I had in my past garden pushed 15 to 18 inches of terminal growth the last two years in my care. At the time of this writing, the specimen pictured here is over 22 feet tall. It was 12 feet tall when it was planted in the Jean Iseli Memorial Garden in 2008.

I will plant ‘Gotelli Weeping’ as a specimen focal point and then add dwarf conifers, Japanese Maples and other ornamental plants to fill in space and add color and texture. “Spillers” in this case may be a combination of ground covering conifers, perennial plants and annual flowers. I my case, I expect that my future garden will be confined to a smaller suburban space, so I will want to plan carefully where I place any larger trees. When planting my ‘Gotelli Weeping’ I will want to provide ample space for it to grow large and to be viewed from all angles.

Next time I will discuss some of the “filler” plants that are high on my list to plant near this fine specimen.

The thrill of spring!

After our unusually dry and mild winter, we have entered into the spring season with cooler temperatures, more clouds, more cold rain and even brief, scattered hail showers. We seem to be back to our “normal” now and many plants are beginning  to push a bit of their new growth. Most of the early Japanese Maples have flushed their first push of fresh colorful new growth. Along with this first push of foliage, we also see tiny, delicate looking flowers, many with bright red or burgundy bracts that are very showy in the green foliage types and almost invisible in the cultivars pushing red new growth.

Bright, fresh, new foliage may be observed to be accompanied by tiny, delicate looking flowers, by those who look closely.

The Ginkgos have pushed some new foliar growth as well, although not near as much as many of the maples. Ginkgo biloba ‘Mariken’ is a very nice dwarf selection and its very tiny, new, bright yellow-green leaves are just beginning to emerge from buds along golden-tan branches.

Ginkgo biloba ‘Mariken’ holds stray water droplets captive in its tiny, emerging spring foliage.

Picea bicolor (alcoquiana) ‘Howell’s Dwarf’ is in beautiful color right now as both the male and female cones are rich purple-pink in color and look gorgeous against the bi-colored foliage of this very attractive small tree. Growing as a wide spreading shrub when young, the small garden tree will eventually set a leader and grow into an upright form. Light green needles with their waxy striations give the plant its distinctive bi-colored look.

The amazing spring color display of Picea bicolor (alcoquiana) ‘Howell’s Dwarf’.

Another exciting selection with bi-colored foliage just beginning to emerge is the low, wide spreading Abies veitchii ‘Heddergott’. Like ‘Howell’s Dwarf’ this slow growing dwarf conifer will eventually begin to grow into a broad upright shape. Its light yellow-green foliage is coated on one side with a thick white wax which is very effective at reflecting light and makes this dwarf fir shine bright in the garden.

Swelling buds are just beginning to break with the emerging new foliage of Abies veitchii ‘Heddergott’.

Intense color that cannot be missed this time of year is when the Abies pinsapo ‘Aurea’ is clustered full of bright purple-pink male pollen cones against the yellow, short, thick, succulent needles on this large garden tree.

Clusters of richly colored pollen cones adorn the short, succulent, yellow-green needles of Abies pinsapo ‘Area’.

I also particularly enjoy the mature, dry cones of Pseudotsuga menziesii ‘Waggin Tails’. This tree seems to set cone at a fairly young age and displays many cone clusters creating a delightful ornamentation to this already unique and appealing, slow growing form of Douglas fir.

Making me nostalgic for Christmas-time, the mature cones and foliage of Pseudotsuga menziesii ‘Waggin Tails’ ornament the gardens beautifully.

What description of spring in the conifer garden would be complete without the reddish-pink new candle growth of Pinus parviflora ‘Tanima no yuki? The newly extending candles of future foliage are always a pleasing sight against the mature, creamy white and green variegated, fine textured foliage of this stunning dwarf Japanese White pine.

Always a favorite sight in the spring are the pink extending candles of Pinus parviflora ‘Tanima no yuki’.

Last on my list of early spring garden stunners are the nearly pure white, bottle-brush flowers of Fothergilla gardenii. This pleasing, small, broad-leaved plant begins its spring season covered with sweet smelling, delicate looking flower spikes. During the summer, its green foliage reminds me of Clark Kent, unassumingly doing their job before the Superman of autumn color explodes onto the scene with mighty shades of red, orange and purple.

The thrilling, white, bottle-brush flowers of Fothergilla gardenii are the first exciting feature of this multi-season plant.

Springtime is a refreshing time of renewal. I hope you have time to stroll through your gardens and be enthralled and energized by all of the activity going on there, wherever you are.
