New Orchid Owner: Identifying Dendrobium vs. Phalaenopsis

Beginner Orchid Care: Dendrobium or Phalaenopsis?

Michelle received an orchid, no info. Blooms quarter-sized, multiple like lily of the valley. 8-oz container, under a foot tall. Main cane (flowering) and two side canes (one almost as thick). Asks: separate canes into new containers? How to separate without harm? Roots like being bound? Light requirements? Window or table okay? North and south windows, light but not much sun. Cats—can orchid make them sick?

Expert Response

Michelle, most common cane-growing orchid is Dendrobium. Dendrobiums grow leaves on canes and flower on them. Phalaenopsis (moth orchid) has all leaves from potting mix, flowers on stems from leaves. Dendrobiums like tight potting; Phalaenopsis do not. Dendrobiums need more light than Phalaenopsis and a rest period with little/no water—just enough to keep cane from shriveling. Water when new canes emerge. South window okay in winter. Send photo for confirmation. These two types need very different conditions.
