All Plants Great and Small

I often fall in love with plants. Then I realize their mature size is more than what a space can handle. The good news is, plant breeders are always hard at work. New plant introductions include columnar and dwarf forms for smaller spaces. If you have an expansive space, no worries. Massive plants that really make a statement are still readily available. But if you have the need for something more petite, there are options for you as well. When it comes to plants, there is something for everyone’s landscape.

Metasequoia glyptostroboides (Dawn Redwood)

The dawn redwood is a fast-growing deciduous conifer. When you think of redwood trees you don’t think dwarf. You probably think of the forests in California with massive trees over hundred and fifty feet tall. If you have the space for a larger specimen, consider planting one of the newer cultivars like ‘Soul Fire’ which comes to life in the spring with lime-green needles tinged with salmon and holds a chartreuse hue through the heat of the summer. If you need something smaller, look for ‘Northlight.’ ‘Northlight’ was discovered in Europe as a witches’ broom mutation. While the ultimate size is unknown, experts anticipate the plant will peak at five to six feet tall.

Prunus (Cherry)

Weeping cherry trees (Prunus subhirtella) have graced gardens for decades. One that seeded into my garden years ago draws visitors into my back yard and demands admiration when in bloom. Recently, I was introduced to a dwarf cherry tree called Zuzu®. Zuzu® (Prunus incisa) maxes out at about eight feet tall and up to five feet wide. A great selection for a small space.

For a small space, like along this driveway, consider Prunus Zuzu® which will reward you with gorgeous spring blooms on a small stature.

Hamamelis (Witch Hazel)

Hamamelis × intermedia ‘Barmstedt Gold’ stands out in my garden in February when it’s in bloom. In addition to the stunning, long-lasting blooms, the fragrance perfumes my entire back yard. The twelve feet tall and wide form demands attention. If you don’t have room for such an expansive specimen, consider planting ‘Quasimodo’ which only grows about four feet tall.

Gingko

I recently saw a mature Gingko at an arboretum in New England that was probably sixty feet tall. During the same visit, I fell in love with a dwarf Gingko at O’Brien’s Nursery. ‘Everton Broom’ grows to about three feet tall in ten years. Gingkos are known for their spectacular, yet fleeting, yellow fall color and fan-shaped leaves. ‘Elmwood Pillar’ is another form that grows taller but stays narrow. Whatever space you have, I’m confident you’ll find a type of Gingko that will work in your garden.

Vernonia (Ironweed)

Vernonia ‘Jonesboro Giant’ is a perennial that grows twelve feet tall and proves that woody plants aren’t the only ones that offer ‘great and small’ options. For a smaller size, consider Vernonia ‘Iron Butterfly’ which grows three feet tall.

I’ve only highlighted a small number of plants offered in the trade in large and dwarf sizes. I’d love to know your favorites worthy of gardens great and small and look forward to learning what choices you make for your own gardens.

Layering in the Garden

Most of you are probably familiar with my friend David Culp’s book The Layered Garden that describes masterful techniques for succession planting. David’s guidance helps to ensure a garden space is always interesting in texture and/or color from season to season. There is another kind of layering too, and it’s a way to propagate our beloved plants.

Some plants layer on their own which makes them effective for erosion control and bank stabilization. Lonicera, Deutzia, Aronia ‘Ground Hug’, Stephanandra, and Symphoricarpos are all good choices for this.

Symphoricarpos layers itself in the landscape, gladly expanding its reach.

Other plants can be layered with some effort like Aesculus, Hydrangeas and many others. Air layering is a technique for tricking a branch into rooting when it’s not in contact with the soil. First you scratch a stem on the plant to expose the cambium. Then you mix some moist potting soil and rooting hormone together in plastic wrap and mold it around the scratched stem, sealing the plastic wrap around the stem to contain the moisture and maximize the stem to soil contact. To eliminate exposure to light, wrap the plastic soil packet with foil. Then wait.

The foil packet looks odd, but conceals a magic process

While the foil package may look a bit suspect to garden visitors, hopefully it will reward you with a clone of your favorite plant. Just like you would check a foil wrapped baked potato in the oven for doneness, after a few weeks unwrap the package to see if roots have developed. If you don’t see roots, seal up the package and check again in a few more weeks. Sometimes the process can take months.

If you are interested in an easier form of layering, take a branch low to the ground on your favorite shrub and place it in contact with the soil. Bury it slightly in the soil and hold it in place with a landscape pin or a rock. With luck you’ll see roots after a few weeks. Sometimes as we work in other people’s gardens, we see layering occur when lower branches have been inadvertently trapped by over-mulching.

A rooted cutting planted and ready for the garden or a friend

Once you see roots on a layered plant, you can cut the branch off the plant and place the rooted cutting in a container to grow it on for a bit until you are ready to place it in the garden or gift it to a friend. I hope you’ll try layering as a technique to share plants or create more of those you want to reproduce. The process is economical, fun and rewarding.
