Is it a root or a stem on my orchid?
An orchid’s stem is its core body, the part where the leaves meet the roots. It can grow roots, flower spikes, or keikis. When it grows a new root, its top will be a bright yellowy-green surrounded by a bright reddish purple; the color varies, but it’s colorful, at least. A flower spike on the other hand is purely a light green, and has a top that has two triangle-shaped spikes stuck together. A basal keiki, i.e. one emanating from the stem, is like a tiny orchid with tiny leaves and roots.
