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.
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.
