Paxistima myrsinites aka Mountain Lover

Paxistima myrsinites is a small evergreen shrub in the Celastraceae family. Its common names include Oregon boxwood and mountain lover. Its native range runs from western Canada to northern Mexico. It grows in temperate regions and is native to Oregon. Oregon State describes mountain populations from British Columbia to California. The species is not native to Britain or Ireland.

This shrub grows low and spreads along the ground. Dense branches give it a close, leafy form. Garden plants reach about 0.7–3 feet [0.2–0.9 metres] tall. Some grow taller than this range. Virginia Tech gives an upper height of 4 feet [1.2 metres]. Its account also notes plants just 1 foot [0.3 metres] tall. In woodland, its small size can make it hard to spot. Pruning can help keep plants low in a garden.

The leaves grow in pairs on short stalks. Each leaf is simple, small, leathery, and free of hairs. Leaf shapes range from oval to broader near the tip. The edges may be smooth or have fine teeth. Teeth tend to occur on the upper half. Virginia Tech describes glossy, dark green upper leaf surfaces. The lower sides are dull and paler green. Oregon State describes the foliage as light green. Slender young stems have four angles in cross-section. Their colour ranges from green to reddish brown. Smooth reddish-brown bark bears small pores called lenticels.

Small flowers grow where the leaves meet the stems. Each has four petals, in red to maroon tones. Oregon State describes the flowers as red-brown. Flowering runs from late spring into the middle of summer. Virginia Tech identifies the species as monoecious. Dry capsules form one to two months after flowering. Each capsule opens into two parts as it dries. Oregon State also records white fruit about a third-inch long.

Grow this shrub in sun or partial shade. Plants take on a more compact form in sun. Oregon State recommends light soil with good drainage. It also calls for soil that is slightly acidic. Heavy clay poses a clear risk to plant health. Losses occur in these soils, with root rot suspected. Oregon State lists hardiness to USDA Zone 5. Its low, spreading form and lasting leaves provide garden interest.
