Acoelorrhaphe wrightii (Paurotis Palm, Saw Cabbage Palm)
Multi-stemmed thin trunks. Taller than European Fan palms. Thorns grow in every direction, leaves palmately lobed and have circular indentation. Fibrous trunk
Chamaerops humilis (European Fan Palm)
Flat, palmately lobed leaves, with deeply bifurcated (split) leaflets. This palm has a leathery joint at base of leaf (hastula--see in picture). Thorns point towards leaves.
Livistona chinensis (Chinese Fan Palm)
Petiole (stem) extends halfway through leaf, causing a SLIGHT curling. Spines point towards base/trunk of tree
Rhapidophyllum hystrix (Needle Palm)
Needles at base, very skinny petiole (stem) with no spines. Leaves deeply bifurcated (split) with "hair" on underside of leaf (feels like rough texture)
Rhapis excelsa (Lady Palm)
Very thin trunks, pink infloresence (blooms) Deeply bifurcated leaves (look like lady fingers cookies...kind of rectangular). Serrated margin
Sabal minor (Dwarf Palmetto, Blue Palm)
About 4ft tall. bluish, waxy coating on leaves. Petiole has no spines
Sabal palmetto (Cabbage Palm)
Petiole extends all the way to the leaf tips, causing leaf to curl (see picture). Round canopy shape. Easily confused with Washington Palm.
Serenoa repens (Saw Palmetto)
Very sharp, serrated petiole (like a saw). Bifurcated tips of leaves, waxy bluish coating (glaucus). Fibrous base.
Trachycarpus fortunei (Windmill Palm)
Can grow large, but very slow grower. deeply bifricated lobes on flat, fan shaped leaves. Very dense fiber that extends off trunk. Skinny petioles. Solitary grower, distinct canopy shape.
Washingtonia robusta (Washington Palm)
Easily confused with Sabal palmetto (Cabbage Palm). The difference is that these leaves are flat and do not curl like the cabbage palm's, and the trunk and boots retain a reddish bronze color.
Butia capitata (Pindo Palm, Jelly Palm)
Bluish color to leaves, downward-cupped leaflets. Pseudo spikes on petiole--actually fibrous hairs.
Phoenix canariensis (Canary Island Date Palm)
Distinct canopy shape. Stout trunk. Yellow infloresence.
Phoenix reclinata (Senegal Date Palm)
Multi-trunked tree. Some trunks lean (recline, "reclinata") Have upward-cupped leaflets that revert to spines towards trunk.
Syagrus romanzoffiana (Queen Palm)
Single trunk, distinct clasping leaf base
Nerium oleander (Oleander)
latex sap, can be causitc. Lancelate leaf, lateral veins form 90 degree angle with midvein. Whirled leaf arrangement like mandevilla which is in the same family.
Trachelospermum asiaticum (Small-leaf confederate jasmine)
latex sap, can be caustic. New growth has smaller leaves. groundcover plant with elliptical leaves and brown, wiry stems
Hedera helix (English Ivy)
Vining habit, uses wrapping stems and adventitous roots to climb. Juvenile leaves have 3 lobes, adult more rounded. Distinct white veination pattern
Fatsia japonica (Fatsia, False Castor Oil Plant)
Palmate lobes, very long petioles, clasping leaf base
Buxus microphylla (Boxwood)
small oval leaves with spine on tip and white midrib on older leaves. dense growth, with lighter green new growth.
