The blue shrimp plant is known by many names: pride of Gibraltar, honey wort, wax flower and Cehrinth major purpurascens. This unique plant is also known by many changing colors. Its flowers are supported by large bracts which change in color from green to purple to blue as the annual matures. Its rounded leaves can also range from green to blue depending on the temperature outside. This plant is popular among gardeners not only because of its color characteristics, but because of relative ease of cultivation. However, for the best results, blue shrimp’s moisture-needy seeds should be germinated indoors and transplanted when they reach a few inches in height and are more drought tolerant.
Soak blue shrimp plant seeds in a bowl of water for 24 hours.
Fill a multi-cell planting tray with a quality seed-starting soil mix.
Water the tray so that the soil is moist but not soaking.
Plant one to two blue shrimp plant seeds 3/4 inch deep in each cell of the planting tray.
Cover the planting tray, and keep it indoors in a location with temperatures around 70 degrees F in a place where it will receive 8 full hours of indirect sunlight.
Uncover the planting tray when the seed germinates in one to three weeks. Keep growing conditions consistent and the soil moist with supplemental watering.
Transplant the juvenile blue shrimp plants when they reach 5 inches in height (in four to six weeks) and all danger of frost has passed.
