Orchids have two vegetative growth types, monopodial and sympodial. Monopodial growth refers to shoots that grow in only one direction, usually vertical.

The more common growth pattern is sympodial, where the orchid stems grow along the surface and develop multiple growing points.

It is common for this type of orchid to have swollen organs called pseudo-bulbs. These organs store food and water. Generally speaking, orchids that have pseudo-bulbs don't need to be watered as frequently as those without.

The leaves of both of these types of orchid are usually thick and leathery with very few markings.
