Buxus microphylla var. japonica 'Green Beauty' (Japanese Littleleaf Boxwood)

April 2026

The 'Green Beauty' cultivar is a selected variety of Buxus microphylla var. japonica, which is native to the islands of Japan. While its wild ancestors thrived in the mountainous regions of East Asia, this specific cultivar was developed for its superior ability to maintain a deep, emerald-green hue even in the face of summer heat and winter chills—conditions that often cause other boxwoods to turn a brassy orange

Before the advent of high-strength plastics and alloys, Boxwood was the gold standard for engineering. Because the wood is incredibly dense and fine-grained (it actually sinks in water!), it was the primary material used for carving printing blocks, chess pieces, and scientific instruments like slide rules and scales.

Care & Keeping
  • Thrives in full sun to partial shade. In extremely hot climates, afternoon shade prevents leaf scorch.
  • Requires regular watering during the first growing season to establish a deep root system. Once established, it is moderately drought-tolerant.
  • Prefers well-drained, neutral to slightly alkaline soil. Avoid "wet feet" to prevent root rot.
  • Best pruned in late spring after the first flush of new growth. Thinning the interior branches occasionally helps improve air circulation.
  • Apply a balanced, slow-release fertilizer in early spring before new growth appears.
Boxwood is often referred to as "Man’s Oldest Garden Ornamental." It was so popular in ancient Rome that Pliny the Younger famously wrote about his Tuscan villa, describing his boxwood hedges clipped into the shapes of letters spelling out his own name—the first century version of a personalized lawn sign!

The photo shows the Buxus after initial pruning for shape & style, but still seated in the nursery "can" that it came in. The plan for this plant is to let it rest & acclimate for awhile, but  re-potting before hot weather.

The Boxwood  has a good headstart on developing a canopy, so I decided to pot him-on. The photo shows him in a full-size training tray, which I had to use to accommodate a large & well-developed root system, which required a root reduction technique, best described as "close your eyes & hack-away". The 'rule of thumb' is to remove no more than about 30% of a root system, at a time..I think I took about 50% of the buxus's root ball.

One of the things that attracted me to this specimen was the "nebari"..the base of the trunk where, as the plant grows & matures, slowly reveals & exposes the juncture of the tree & his roots.



The trunk has the "weathered" look, as if he were much older; part of this is because it IS older than you would think..I am told that it takes 7 years to grow the typical boxwood for retail sale.











This little tree is healthy, strong & seemingly up for anything, so it will be fun to watch how he develops over the next few months.
