One-seeded Ethionema. FI. Jul. Aug. Clt. 1778. Pl.4to4 ft. 
Cult. The shrubby kinds of this genus should be kept in pots, 
which should be well drained with potsherds and treated like 
other alpine plants. A mixture of sand, loam, and peat suits 
them best, and cuttings planted under a hand-glass in the same 
kind of soil will root readily, or they may be increased by seeds. 
Some of the more hardy species may be planted on rock-work, 
which by their dwarf growth they are well adapted for. The 
annual and biennial species may either be sown on rock-work or 
in the front of the flower-border. A light dry soil suits them 
best. All the species are worth cultivating.

nate with toothed leaflets, but becoming more simple as they

botanic gardens. They only require to be sown in the open 
ground or on rock-work, for which, from their low growth, they 
are well adapted.

of this genus furnishes a blue dye, which is used by dyers in 
various ways. This dye is perfectly like indigo, and is often 
used as a substitute for it, especially that obtained from Zsàtis 
tinctoria.
