How to keep Verbena Incompta.
Light
Purpletop vervain is a perennial herbaceous plant that prefers sunny sites and comes from open habitats, commonly growing in meadows and grasslands. It favors full sun but can also tolerate partial sun.
Water
Purpletop vervain needs regular watering throughout the spring and summer months. As the seasons change to fall and winter, you can reduce the frequency. During hot weather, check the plant daily. If the soil feels dry or the plant starts to wilt, it's time to water. Water the plant at its base in the morning to protect its delicate petals from damage.
Temperature
Purpletop vervain can tolerate a broad range of temperature conditions, but its distribution may still be limited by different combinations of water and heat. It does best in warm summer climates with adequate rainfall or regular watering. Extended periods of cloudy, rainy weather or sustained high temperatures can raise the chances of Purpletop vervain dying. In winter, protecting the plant from cold can improve its survival rate.
Fertilizer
The best time to fertilize Purpletop vervain is in early spring, when it is coming out of dormancy and starting active growth. Fertilization supplies essential nutrients for healthy development. Although Purpletop vervain needs relatively little fertilizer, an annual application can improve its survival and encourage better, longer-lasting blooms.
Pruning
Purpletop vervain typically grows to a height of 10 cm to 140 cm and can spread up to 2 meters wide. It blooms from early summer until mid-winter. To maintain its shape and encourage blooming, prune the plant monthly during the summer and twice each season at other times. Trim back 1 to 2 inches during each pruning, but avoid removing more than a third of the plant at once.
