The many flowers that bloom in June nearly defy listing. The warmth, sunlight and precipitation of June make it a perfect time for many plants to start flowering. Among the plants that bloom in June are ajuga, bugloss, columbine, varieties of anemone, basket-of-gold, dianthus, foxglove, iris, peonies, soapwort, meadow rue and others.
Ajuga is often used as a ground cover because it forms mats of pretty, heart-shaped leaves topped by flowers that grow on erect stems. The flowers can be white, pink, violet or blue. The leaves themselves can be different colors ranging from deep green to cream mottled with pink. Ajuga thrives in acidic, loamy soil that is well-drained and in full sun to light shade.
Bugloss has beautiful blue, pink or white clusters of flowers that shoot up above tongue-shaped leaves. The blossoms can last for over a month. The plant, which can grow from 3 1/2 to 5 feet tall, can have a second blooming. Taller varieties of bugloss may need to be staked. This plant should be placed in loam that is very well-drained and in full sun to light shade.
Dianthus are also called pinks or carnations. The flowers are fragrant and fringed, and they can be white, pink or red. Dianthus thrives in well-drained, somewhat alkaline loam and full sun.
