A genus of hardy plants, Gentians belong to the order Gentianaceae. They have a bitter taste, and one species, G. lutea, is largely used as a bitter tonic in medicine. Gentians are not easy plants to establish in a garden, on account of their need of root moisture and their dislike of root disturbance. It is best to raise them from seed, although slow to germinate. The most commonly cultivated Gentian is the Alpine G. acaulis, with large, deep-blue flowers on a dwarfed plant.

Geum urbanum is a member of the genus Geum, a genus of hardy plants (Rosaceae). Not usually used decoratively, their five-parted flowers being borne singly at the ends of much-branching stems. The leaves are generally odd-pinnate, often with small leaflets scattered among larger ones. The style is persistent in the fruit and is often plumose, as in the purple avens (G. ciliatum), which has violet flowers. The white avens (G. canadense) has a prickly receptacle, as has the G. flavum. Among the most common species are the yellow G. strictum and the G. vernum, both found in shady, damp places.

British Golden-rod is a member of the large composite genus Solidago, which is chiefly North American. The golden-rods are erect plants, little branched, and often somewhat woody at the base. The foliage is various, usually somewhat lanceolate in shape, and sometimes conspicuously veined. The tiny heads have one series of white or yellow ray-flowers, and are gathered into various forms of inflorescence, often of a massive character; they appear in late summer and early autumn. Although of no commercial value (except as forage for sheep) the golden-rods are conspicuous for their bright color, especially as they are apt to grow in huge colonies in fields and along roadsides.

Larch, or Larix, is a genus of hardy, deciduous, coniferous trees of very graceful habit. They bear monoecious flowers, the male catkins being small and oval, whilst the female ones are much longer. The leaves are bright green, linear, soft, and usually produced in short bundles on each side of the spray. They appear very early in the spring. The timber, which is very hard and tough, is much used in shipbuilding and for railway sleepers, and in cabinet work is capable of taking a very high polish. The species most commonly planted is 'L. europaea', whcich grows to about 100 ft in height. Other species are 'L. occidentalis', a tall and handsome American tree and 'L. laricina', the tamarack, or hackmatack, of North America. This is a straggling tree, most common in swampy soils, with smaller cones than has the the European species. It reaches a height of 70 ft., and the wood is valuable for the same purposes  as that of other larches.
