 Deciduous tree, up to 4m (cultivars) or 12m (wild) tall. "The tree originated in Central Asia, where its wild ancestor, Malus sieversii, is still found today. Apples have been grown for thousands of years in Asia and Europe, and were brought to North America by European colonists... There are more than 7,500 known cultivars of apples, resulting in a range of desired characteristics." [[http://en.wikipedia.org/wiki/Apple]] Deciduous tree, up to 4m (cultivars) or 12m (wild) tall.

 +"The extract of ‘Redgold’ flowers, which is one of apple cultivars, was fractionated by column chromatography and analysed with GC and GC-MS. Seventy-seven compounds were identified and cis-hex-3-en-1-ol, benzyl alcohol, 2-phenylethyl alcohol, cinnamyl alcohol, nonanal, octanol and indole were found to make a major contribution to the odour of apple flowers." \\

 Main compound in the headspace of apple flowers was benzaldehyde (13%), followed by geranial (7%) and neral (7%), limonene (5%), 3-carene, α-pinene, terpinolene, benzylalcohol, geraniol,  cinnamaldehyde (4% resp.), and α-humulene, 2-phenylethylalcohol, benzyl acetate, and 2-phenylethyl acetate (3% resp.). Minor but olfactory important components were eugenol (1.1%), hexanol, 3-hexenol, linalool, menthol, thymol, vanillin (trace), decanal, β-ionone, bornyl acetate, geranyl acetate, hexyl acetate and 3-hexenyl acetate. \\ [Buchbauer, Gerhard, et al.

 +"Headspace solid-phase microextraction (HS-SPME) combined with gas chromatographymass spectrometry (GC-MS) was applied to measure and analyze the volatile components of live flowers after anther dehiscence during apple blossom... Benzyl alcohol, cis-3-hexenol, linalool, and neryl nitrile were the main volatile components in Fuji apple flowers." \\
