Companion Planting with Dianthus
When it comes to dianthus plant companions, look for plants that share the same growing conditions. For example, dianthus prefers bright sunlight and well-drained, dry soil, so plants that like shade and moist soil aren’t good companion plants for dianthus. Often, other old-fashioned flowers, like roses or verbena, complement dianthus beautifully. Mild-scented flowers, such as lavender or scented geraniums, work well, but be careful of strong-scented plants that may detract from the aroma of dianthus. Consider color as well, and what combinations are pleasing to your eye. The red, pink, white, and purple shades of dianthus may be overpowered by bright orange marigolds or intensely colored Kniphofia (red hot pokers). However, this is a matter of personal preference. Otherwise, if you like the appearance and color of a plant, go ahead and give it a try. Chances are, you’ll find a number of choices that work well with dianthus.
