Uncommonly Common

Juniperus communis is a common landscape juniper with a wide natural distribution…one of the widest of any woody plant in the entire world.

In the North American part of its range, it’s widespread throughout the Western US, and across the northern tier of the country all the way to Maine. East of the Mississippi River, however, it’s virtually not-existent south of the Great Lakes.

Patrick McMillan had been telling us about a population he rediscovered from an earlier Henry William Ravenel (1814-1887) documentation of a single clone growing naturally in Aiken, South Carolina. Last week, we made the 4 hour drive to visit this ancient living fossil. Here is all that remains, growing in an amazing nature park, known as Hitchcock Woods, where it grows surrounded by a forest of Kalmia (mountain laurel).

We have this propagated and growing at JLBG, and hopefully in the future, when our plants get larger, we can share these amazing genetics with a wider audience.

A Golden Native

Here’s a photo this week of one of our favorite North American native plants, Juniperus horizontalis ‘Copper Harbor’. This would certainly add significant year round color interest to any native plant garden. In our trials, this is far and away the best of the golden Juniperus horizontalis cultivars. We offered this selection for a couple of years, but there seemed to be little interest.

Kaizuka! Bless you.

I first met Juniperus chinensis ‘Kaizuka’ on a mid 1970s student field trip to Florida with the late JC Raulston. As our caravan of University vans crossed from Georgia into Florida, these junipers suddenly appeared everywhere. Although, I was unfamiliar with this architecturally fascinating specimen, I was in love….despite it being common as the proverbial dirt in Florida landscapes. Everywhere from gas stations to the poorest home seemed to have at least one. Most locals know Juniperus ‘Kaizuka’ as either Juniperus ‘Torulosa’ or Hollywood Juniper…a common name it gained due to its ubiquitous presence around Los Angeles. It turns out that Juniperus ‘Kaizuka’ was an introduction from Japan’s Yokohama Nursery prior to 1920. Our oldest plants at JLBG are now 33 years old, and now measure 24′ tall x 16′ wide. The one pictured below is a new 5 year old planting in a new section of the garden. Forty-five years later and still in love!

Proud to be a Siberian

We don’t have many Siberian plants which thrive in the southeast US, so we get pretty excited when we find one that does. I was introduced to Microbiota decussata by the late JC Raulston, back in the mid 1970s, and actually still have one of my original plants that’s still alive. Many years later, a much improved form came to market under the name Microbiota decussata ‘Prides’.

Microbiota is a monotypic genus of conifer that has a textural appearance somewhere between a Juniper and a Selaginella.  In the wild, Microbiota can only be found in one small region of the Sikhote-Alin mountains, which is about 500 miles north of Vladovostok, Russia, where it occurs between 6,500′ and 7,000′ elevation.

Although Microbiota was officially discovered in 1921, and published in 1923, the Russian government, long-known for its secrecy, kept it completely under wraps until the early 1970s.

Unlike most junipers, which need sun to thrive, microbiota prefers shade to only part sun. Consequently, it you like this texture and don’t have full sun, this is the plant for you. For us, it matures at 18″ tall x 6′ wide.

Green Eggs and ….pancakes?

Most everyone is familiar with Blue rug juniper…aka: Juniperus horizontalis ‘Wiltonii’, but few people know its dwarf cousin, Juniperus horizontalis ‘Pancake’. This amazing selection of the North American native groundcover is much slower growing, shorter, and with much finer textured foliage. Here is a recent photo of this amazing plant in the gardens at JLBG. Why is it that we never see Juniperus horizontalis touted for native plant gardens…hmmm?
