The differences that matter
Pet safety
This is the difference that matters most. Kentia palm is listed non-toxic to cats and dogs; Dragon tree is toxic (saponins). If the two are sold under the same name, a mislabelled plant is a genuine risk in a house with animals.
Mature size
Kentia palm reaches about 120 inches; Dragon tree tops out near 96. Buying the wrong one for a shelf means rehoming it in a year.
Habit
Dragon tree grows upright; Kentia palm grows clumping. That decides where each one physically works.

Dragon tree is Asparagaceae, Kentia palm is Arecaceae. They share a shop label and nothing else — different families, different continents, different care.
Which should you buy?
- With a cat or dog in the house, take Kentia palm. The other is toxic, and if the shop label is wrong you will not know which you have brought home.
- In a dim room, take either — both have a low light floor.
- If you forget to water, take Dragon tree, which goes 14 days between drinks.
- If it is your first plant, take Kentia palm, at 1 of 5.
- For a small shelf, take Dragon tree, which stops around 96 inches.
