Gilia (gil-ia, after Seiior Gilio. Ord. Polernoniaceae). The most 

 popular members of this small genus are the hardy annuals tricolor 

 and alba, which grow about a foot high and bloom in summer; but 

 there is a much finer plant in the old species coronopifolia, which 

 grows about 30 ins. high and produces beautiful rosy flowers in 

 summer. It is best treated as a biennial (see Biennials). Tricolor 

 is illustrated in the Botanical Magazine, t. 3463.

 foliage resembling that of the Maidenhair Fern. It does not grow 

 rapidly, and may therefore be used as a lawn tree in small gardens. 

 It thrives near towns, and will grow in any well-drained fertile soil. 

 It may be planted in autumn or spring. Propagation is by seeds 

 sown in heat in spring. There are several garden forms of it, such 

 as laciniata, fastigiata, and pyramidalis.
