seed sown as soon as it is ripe; if left till spring before it is sown
it will probably not come up till the second year. The perennials are
increased by dividing the roots. Both of the latter kinds do best in
a dry, sandy soil. Gentiana Acaulis, or Gentianella, is very suitable
for edgings, or for rock-work; it is an evergreen creeper, and bears
large trumpet-shaped flowers of rich ultramarine blue. All the
Gentians need plenty of free air, and some of them moisture at the
roots. Bloom in July. Height, 4 in. to 2 ft.
