Sapphire flower is a type of annual flower that blooms heavily from early spring until the fall frost and throughout the year in sunny windows or greenhouses. They thrive best in cool or coastal gardens, but with partial shade or an eastern exposure, they will grow consistently well in other areas.

B. speciosa varieties of Sapphire flowers grow in a loose mound, reaching 18 inches in height and width, allowing them to trail. The most commonly planted variety of B. viscosa (Sapphire) is a stiff, compact plant that does not trail.

To grow Sapphire flowers, plant them in rich, well-drained soil, but keep the soil moist. Larger varieties should be spaced 10 inches apart, while dwarf ones should be spaced 6 inches apart. Browallia is an excellent shade plant, although with a looser habit and sparser flowers. Fertilize lightly on a biweekly schedule, or incorporate a summer-long, slow-release fertilizer in the soil at planting.

Sapphire flowers can be propagated by seeds or cuttings. Start seeds indoors 6 to 8 weeks before planting out after the last frost. Seeds require light to germinate, so do not cover them. At temperatures of 70 to 75 degrees Fahrenheit, they will take 14 to 21 days to germinate. Softwood cuttings taken in the spring or fall root promptly. To grow larger plants in 10-inch hanging baskets, add 4 weeks to the growing period.

Sapphire flowers are great for beds, borders, or rock gardens. Compact plants make good edges for tall borders. They are also excellent container plants.

The most commonly planted speciosa Sapphire flower varieties are the Bells: Blue Bells Improved, mid-blue and most popular, Marine Bells, a deep indigo blue, Sky Bells, a clear azure blue, and Silver Bells, pure white. Viscosa varieties include Sapphire, a deep blue with a white eye, Blue Troll, a mid-blue dwarf variety, and its counterpart, White Troll.

The scientific name of Sapphire flower is Browallia speciosa, viscosa.
