Trees - Misc

The goal of this list is species that can be trimmed to look like scale trees. Many of these need trimming to be started early on. As usual, controlling the size of the root ball can control the size and growth rate of the "tree"

Rosmarinus officinalis
Rosemaries

can look like desert tree or chaparral - has flowers (what time of year?)

Rosemary is a long-lived, semi-woody, tender perennial herb that can become a bonsai in a single year with a minimum of effort. Rosemary can reach a maximum height of 48" if field grown in only three years and live as a bonsai for over 30 years. Since the Rosemary's leaves are needle-like, the plant is most often grown in the same classic bonsai styles as the pine.

Rosemary has been long cultivated as an herb and ornamental. The herb now is available in an astounding number of cultivars (24!) with an abundance of flower colors (Blue, Violet, Pink, White), scents (Pine, lemon), and growth habits (upright, twisting, creeping). There's even a variegated cultivar. With some cultivar hardy to zone 7, Rosemary can be grown out-of-doors all year round. In colder climes, the herb can successfully be overwintered indoors under lights.

Lighting and Temperature

Full Sun in all zones, a minimum of 6 hours of direct sunlight per day during spring/summer/autumn. When overwintering indoors, give it 14 hours under full-spectrum lamps or a sunny spot with direct morning sun.

Rosemary is a tender perennial in zones 11-7 and an annual in zones 6-3. For a bonsai, bring indoors before first frost date. A single light frost is unlikely to kill any cultivar of rosemary. A properly hardened off Rosemary (of the hardier cultivar) can withstand brief 20F temperatures if field planted. During indoor wintering, give it cool days (~70F) and cooler nights (65-60F)with lots of morning sun, no afternoon sun, and lots of air circulation.

Water and Fertilizer

Rosemary does not like wet feet. It can survive dry soil for a day or two. Best to let the soil dry out almost completely then water. Use a chopstick to determine soil moisture. When the chopstick is pulled out and feels totally dry (cannot smear mud on dry paper), then water. Only water in the morning to prevent the roots from sitting in water overnight.

Humidity should be maintained at over 50% (relative) with the use of a humidifier or humidity tray.

Use 20:20:20 non-acidic liquid fertilizer every other week as long as day temperatures are above 50F. While wintering indoors, reduce feeding to once monthly. Watch for nitrogen deficiency, especially with the organic mix given below. Time released Oscomote (36:18:12) also has proven to work well. There is no need to dilute fertilizer past the manufacturers recommendation.

Repotting

Repot every other year in very well drained mix of 50% organics such as screened fir or pine bark and 50% inorganics (pumice, perlite, haydite, etc). Add limestone or dolomite to the soil mix to buffer the pH of the soil mix. Do not use peat moss.

Try to limit any root pruning to the early spring, before the new growth gets too advanced. Never root prune by more than 1/3 during any year.

Styling

Rosemary comes in both upright and prostrate varieties. Rosmarinus officinalis forms itself into a striking formal upright with minimum effort. The prostrate varieties can be formed into everything from informal upright cascade to windswept. The only style that the species does not lend itself to is root over rock.

Clip and grow is the best styling method since the wood, once hardened, is impossible to bend without splintering. You can pinch new growth after the first sets of leaves completely open. Start midsummer by cutting back top foliage to old wood to encourage some of the lower and finer branches to expand and thicken.

Propagation, Pest and Diseases

Usually grown from softwood and semi-hardwood cuttings in summer using low IBA rooting hormone. Rootone TM, or Hormex #1 or #3 TM or Dip and Grow TM at 20:1 dilution are sufficient. Cuttings are placed in sterile media and root in 2-4 weeks.

Rosemary is subject to root rot in poorly draining soils or when grown in inadequate light.

Snow Rose

also "Pink Princess" variety, can "Cherry Blossom" variety

 Serissa Foetida also known as White Swan?

Foetida likes partial sun, crassiramea likes full sun. The growth is sensitive to light, too little will not give you the nice compact growth, changes in light upsets the Snow Rose.
Likes slightly acid soil, tolerates USDA zone 9, full sun moderate water

The snow rose or tree of a thousand stars (Serissa foetida (L.f.) Poiret ex Lamarck) is a unique member of the Rubiaceae, the madder family. Native to open woodlands of Southeast Asia, China, Taiwan, and southern Japan, the snow rose is a small evergreen shrub with tiny opposite leaves and petite funnelform flowers. Like its cousin, the coffee, the plant bears berries with 2 seeds.

succlent - move!!

full sun, light to moderate water

Ulmus
Elms

most elms like moderate water and full to moderate sun

Ulmus neri
Cork Bark Elm

The Neri Elm has small serrated green leaves with good fall color. It has a striking gnarled corky bark appearance hence the name Cork Bark Elm. Deciduous.

Ulmus parvifolia 'hokkaido'
Hokkaido Elm

Native to Japan and Korea, the Hokkaido Elm is a Chinese Elm, not troubled by the Dutch Elm disease that has destroyed so many other species. It is extremely slow growing and will grow only to about 18" tall. The Hokkaido forms a rugged trunk with a corky bark that flakes off in rounded plates. This cultivar of ulmus has the tiniest leaf of all Elms (only 3/8" long)and they are short-stalked, oval with a slightly pointed tip and toothed margins, bright green on the upper surface, lighter green underneath. Very nice fall color. Deciduous. Temperate. Protect from frost. Full sun, moderate water

Ulmus parvifolia 'seiju'
seiju Elm

Ulmus x hollandica 'Jacqueline Hillier'
Jacquline Hillier Dwarf Elm -

Formerly called Ulmus x elegantissima 'Jacqueline Hillier,' & still commonly sold by that name. Because of a long period of uncertainty about its parentage, it is still sometimes sold as U. minor or the synonymous U. carpinifolia.

'Jacquelline Hillier' is a beautiful dwarf elm that can be grown in the garden as a shrub or dwarf tree, or in containers, or as bonsai. Because the leaves are micro versions of a full-sized elm, it is a particularly good visual choice for bonsai, as it can truly look like a miniature of a gigantic elm.
They are very winter-hardy to minus ten degrees F. or even colder, & go through all the expected seasonal changes of a temperate deciduous tree, though holding their tiny leaves until the start of winter, growing them back come April.
