In the real BDSM (bees, dirt, seeds, and manure) world of plants, there are some vegetative members who are by nature dominating and others, submissive.
These characteristics, as in the real world of animals, may be quite covert.
So, before you bring that plant home from your blind date at the garden store, a little research may be in order.
Plant tag and catalog descriptions may only prove more confusing: water plant, attracts hummingbirds, prefers sharply drained soil, heat tolerant, prefers shade, spreading habit, use slow-releasing fertilizer – oh my!
In the end, there are plants who grow slowly and steadily, and if in the right location, will thrive. There are others that, given their druthers, will stomp out all others – dominating their territory. Beware – Campanula glamorata “Christian”, no matter how compelling.
