Palm trees are popular landscaping plants in tropical regions, especially in coastal areas. They are resistant to storm winds, while offering a tropical ambiance to the landscape they are located in.[1]Planting one can be a daunting job, so this article may help understand what it takes.

It is a herbaceous perennial plant growing to 1.5–3 metres (4 ft 10 in–9 ft 10 in) tall with opposite leaves on the upper part of the stem but alternate below.[3] The leaves have a rough, hairy texture and the larger leaves on the lower stem are broad ovoid-acute and can be up to 30 centimetres (12 in) long, and the higher leaves smaller and narrower.
The flowers are yellow and produced in capitate flowerheads, which are 5–10 centimetres (2.0–3.9 in) in diameter, with 10–20 ray florets.
The tubers are elongated and uneven, typically 7.5–10 centimetres (3.0–3.9 in) long and 3–5 centimetres (1.2–2.0 in) thick, and vaguely resembling ginger root, with a crisp texture when raw. They vary in colour from pale brown to white, red, or purple.[2][4]
The artichoke contains about 10% protein, no oil, and a surprising lack of starch. However, it is rich in the carbohydrate inulin (76%), which is a polymer of the monosaccharide fructose. Tubers that are stored for any length of time will digest their inulin into its component fructose. Jerusalem artichokes have an underlying sweet taste because of the fructose, which is about one and a half times sweeter than sucrose.[5]
Jerusalem artichokes have also been promoted as a healthy choice for diabetics. This is because fructose is better tolerated by people that are diabetic. It has also been reported as a folk remedy for diabetes.[5] Temperature variances have been shown to affect the amount of inulin the Jerusalem artichoke can produce. When not in tropical regions, it has been shown to make less inulin than when it is in a warmer region
