Whirling butterfly plant, also known as Gaura lindheimeri, is a beautiful and low-maintenance perennial that produces delicate, butterfly-like flowers that sway in the breeze. This plant is easy to grow and looks great in beds, borders, and containers. Here’s everything you need to know about growing whirling butterfly plant outdoors.
Whirling butterfly plant thrives in full sun and well-draining soil. Choose a spot that receives at least six hours of direct sunlight per day. The soil should be well-draining and not too heavy or clay-like. If your soil is heavy, amend it with organic matter like compost or peat moss to improve drainage.
Plant whirling butterfly plant in the spring after the last frost date for your area. Dig a hole that is twice as wide as the root ball and just as deep. Place the plant in the hole and backfill with soil, pressing down firmly around the base of the plant to remove any air pockets. Water thoroughly after planting.
Whirling butterfly plant is drought-tolerant once established, but it still needs regular watering during the first growing season to get established. Water deeply once or twice per week, depending on weather conditions. Do not overwater, as this can lead to root rot.
Whirling butterfly plant does not require much fertilizer. You can apply a balanced fertilizer (10-10-10) once in early spring before new growth appears. Avoid fertilizing after midsummer, as this can stimulate new growth that may not have time to harden off before winter.
