Trachycarpus fortunei

























Botanical Name: Trachycarpus fortunei
Common Name: Windmill palm Chinese Windmill palm
Family: Aracaceae ( Palmae )
Type: Broad leaved evergreen palm tree 
Origin/Habitat: Central China Myanmar & Northern India
Leaf Character: Long petiole bare except for two rows of small spines, terminating in a rounded fan of numerous 
leaflets; each leaf is 140–190 cm long, with the petiole 60– 100 cm long, and the leaflets up to 90 cm long
Flower Type: The flowers are yellow (male) and greenish 
(female), about 2–4 mm across, borne in large branched panicles up to 1 m long in spring  it is dioecious, with male and female flowers produced on separate trees.
Fruit:The fruit  is a yellow to blue-black, reniform (kidney-shaped) drupe 10–12 mm long, ripening in mid autumn.
Bark: The trunk is very rough with the persistent leaf bases clasping the stem as layers of coarse fibrous material.
Exposure: Full Sun to light Shade
Water: Regular water 
Remarks: Grows to 12–20 m (39–66 ft) tall on a single stem up to 15–30 cm diameter. Fibers are collected from the leaf bases and made into coats and other items (brooms, brushes, doormats); wax is collected from the fruits; and a hemostatic drug is extracted from the seeds. This species is widely cultivated as an ornamental, especially in cooler climates. Windmill Palm works well as a framing tree, accent, specimen, patio or urn subject. It is ideal for use as an accent in a shady shrub border or by a front entryway. It does well in confined areas and is hardy to 10-degrees F. or lower. 
Management: Windmill Palm should be grown in shade or partial shade on fertile soil to look its best, but it is also tolerant of full sun on well-drained soils when given ample moisture in the northern part of its range. Plants should be watered faithfully. Protection from harsh winds will minimize leaf tearing, but plants can be used successfully close to the shore, being quite tolerant of salt and wind. There are fine examples of mass plantings where palms are spaced six to 10 feet apart around a patio or sitting area. They have also been used very successfully lining an entry walk to a large building. This adds a formal elegance to any structure, especially one with a glass facade.
Propagation: By seed.
Pests: Scales and palm aphids 
Diseases: Root rot, moderately susceptible to lethal yellowing disease, and leaf spots.

Syagrus romanzoffiana















Botanical Name:Syagrus romanzoffiana
Common Name: Queen palm 
Family: Arecaceae (Palmae)
Type: Broad leaved evergreen palm tree
Origin/Habitat: Native to Argentina, Brazil & Bolivia
Leaf Character: Alternate, pinnately compound, up to 15 feet long; individual leaflets, lance shaped and 2 to 3 feet long, dark green, gracefully arching.
Flower Type: Occur on dense, hanging many-branched cluster, creamy yellow-white, appearing in spring.
Fruit: Fleshy drupe, round, 1 inch in diameter, yellow-brown to orange-brown, date-like, occurs in up to 6 feet hanging clusters, may be produced in quantity, ripening late summer to early winter.
Bark: Light grayish brown, ringed, becoming more smooth and cement-like with age.
Exposure: Full Sun to partial shade 
Water: Regular  to ample water
Remarks: Tall, slender, straight tree reaching up to 50 feet tall, gracefully feathery top.
Uses: specimen; deck or patio; parking lot island 100-200 sq ft; parking lot island > 200 sq ft; sidewalk cutout (tree pit); tree lawn 3-4 feet wide; tree lawn 4-6 feet wide; tree lawn > 6 ft wide; highway median
Management: Growing best in full sun, most suited for acidic, well-drained soils and shows severe mineral deficiencies on alkaline soil. This disfigures the palm by stunting the young leaves and can kill it. Unfortunately, Queen Palm is frequently planted in alkaline soil and requires regular preventive applications of manganese and/or iron to help keep the fronds green. Potassium deficiency is also displayed on older fronds in well-drained soils. Quick-growing Queen Palm responds well to ample moisture and fertilizer and is slightly salt-tolerant. After planting Queen Palm in the landscape, growth is rapid. 
Pruning off too many fronds at one time can cause the palm to decline. Growth often slows with new foliage aborting to display distorted leaflets. The trunk is also very susceptible to decay. Prevent injury to the trunk by keeping turf well away from the trunk.
Propagation: is by seed and volunteers will often appear under fruiting trees.
Pests :Palm leaf skeletonizer and scale are problems for Queen Palm.
Diseases: Ganoderma butt rot can kill Queen Palm. It probably enters the trunk most often through wounds in the lower trunk and roots. There is no control for butt rot, only prevention.

Rhapis excelsa










Botanical Name: Rhapis excelsa
Common Name: Broadleaf Lady Palm
Family: Arecaceae
Type:  Broad leaved deciduous shrub/palm tree
Origin/Habitat: Southern China and Taiwan.
Leaf Character: Glossy, palmate leaves divided into broad, ribbed segments. Leaf segments are single or few in young plants and increase to a dozen or more in mature plants; segments are divided to the petiole. Leaf-ends are sawtoothed unlike most other palms, occurring on slender petioles ranging from 20 to 60 cm in length.
Flower Type: small inflorescence at the top of the plant with spirally arranged, fleshy flowers containing three petals fused at the base.
Fruit: Ripe fruit are fleshy and white  1 to 3 inches  
Exposure: Some shade, bright indirect light 
Water: regular water
Remarks: It is not known in the wild; all known plants come from cultivated groups in China. They were first collected by the Japanese for Tokugawa shogunate palaces, then popularity spread to Europe, and later to America where its low light and humidity requirements make it a common feature in malls and offices. grows up to 4 m in height and 30 mm in diameter in multi stemmed clumps.
Management: Forms dense clumps of bamboo-like stalks topped with very dark green, broad, fan-shaped leaves  Performing well in north-side foundation plantings or other shady locations, slow-growing lady palm is also ideal for containers. They lend a rich tropical look to the landscape. Lady palms can be effective accents in a shrub border or near an entryway. Plant on three- to four-foot centers to create a mass effect.
Management:  Needs partial to deep shade and fertile organic soil to look its best but will tolerate the poor light, dust, and drought usual of indoor container culture. Be sure that drainage is adequate for indoor use.
Pest:  Scale, palm aphids, sooty mold, and caterpillars, 

Propagation: Spreading slowly by underground rhizomes & offshoots, is usually propagated by division

Phoenix roebelenii



















Botanical Name: Phoenix roebelenii
Common Name:  Pygmy date palm or miniature date palm
Family: Arecaceae (Palmae)
Type:  Broad leaved evergreen palm tree
Origin/Habitat: Southeastern Asia, from southwestern China (Yunnan Province), northern Laos and northern Vietnam
Leaf Character: The leaves are 60–120 cm (24–47 in) long, pinnate, with around 100 leaflets arranged in a single plane Each leaflet is 15–25 cm (6–10 in)1525 cm long and 1 cm broad, slightly drooping, and grey green in color with scurfy pubescence below.
Flower Type: The flowers are small, yellowish, produced on a 45 cm (18 in) inflorescence
Fruit: The fruit is an edible 1 cm drupe resembling a small, thin fleshed date
Exposure: Full to partial Sun, parial shade
Water: Regular Water
Remarks: small to medium sized, slow growing slender tree growing to 2–3 metres (6.6–9.8 ft) tall. is a popular ornamental plant in gardens in tropical to warm temperate climate areas. With a minimum temperature requirement of 10–16 °C (50–61 °F), in cooler areas it is grown under glass or as a houseplant.  Has an upright or curving, single trunk topped with a dense, full crown of gracefully arching, leaves. Pygmy Date Palm is quite popular as a specimen planting or in containers, especially attractive at poolside. It is usually used as a single specimen although it is also effective in groups of three or more
Management: Pygmy Date Palm should only be grown in frost-free areas in sun or shade on well-drained soils. Plants should be regularly watered. Magnesium or potassium deficiency symptoms (chlorotic and spotted older fronds) often develop on the older leaves when grown in soils with a pH above 7. It has some salt tolerance, surviving on the inland side of coastal condominiums.
Propagation: By seed.
Pest: Palm leaf skeletonizer and a large number of scales can infest this palm.
Diseases: Leaf spot and bud rot are two diseases which can infect this palm.
Cultivars:  
P.canariensis Canary Island Date Palm
P. dactylifera Date Palm
P. reclinata Senegal Date Palm
P. roebelenii Pygmy Date Palm
P. rupicola Cliff Date Palm

P. sylvestris Silver Date Palm
