Inca.rvillea< — One of the most interesting and beautiful 
of hardy perennials is I. Delavayi, a plant with tuberous roots, 
elegantly cut foliage, and lovely rosy-carmine, trumpet-shaped 
flowers borne in racemes in May and June. The plant grows 
about 2ft. high, is a native of China, and belongs to the Big- 
nonia family (Bignonraceae). An exceedingly handsome plant 
for a well-drained sunny and choice perennial border. I. grandi- 
flora, rich carmine, 1 ft. , and I. g. brevipes, deep crimson, a 
new kind from China, are both charming additions to the 
genus. They require a deep, rich, loamy, well-drained soil and 
a sunny position. Plant in March. In severe winters protect 
the crowns with bracken, litter, or a layer of ashes. Increased 
by seeds sowm in gentle heat in March, planting out the seed- 
lings in June ; also by division of the roots in March. All 
summer-flowering. The very pretty, fern-like foliage adds 
very greatly to the charm of these plants when in flower. 
Inula (Elecampane).— Hardy herbaceous perennials, be- 
longing to the Daisy order. They are all yellow^ or orange

They are, moreover, showy border plants. The best species
