Evening Primrose. See Œnothera.
Exacum. Gentianeæ.
Seeds should be sown in spring, in bottom heat.
Exochorda. Rosaceæ.
Grown from seeds, layers, cuttings and suckers. Seeds are difficult to procure. Layering in June is a common practice. Various kinds of cuttings are employed, but the best results follow short, soft cuttings, taken from forced plants and set deep in shallow flats of sand. They require a very strong bottom heat, a close frame, and the water should be applied in a spray upon the foliage. Cuttings are sometimes grafted upon pieces of roots. It is regarded as a difficult plant to propagate.
Fabiana. Solanaceæ.
Readily increased by seeds and cuttings.
Commonly grown from the nuts, which should be stratified and sown very early in spring. They may be sown immediately after they are gathered, if they can be protected from vermin. The named varieties are grafted upon the European or American species.
Fair Maids of France. See [Ranunculus].
