Snow Fountain' and 'Giant White' are larger-flowered, modern strains. The annual gypsophilas have smaller, usually single flowers, but are otherwise similar and can be easily grown in the cutting garden. Seeds are sown directly where the plants are to grow and thinned to 15-20 cm apart. Baby's breath can be grown as a filler in borders, but the short season limits its use. Sown in bulb beds it can be used to hide unsightly fading leaves in the summer.
