NOLANA. 
Nolanas arc trailing, hardy annuals. Prefer a light 
soil. Seed may be sown in the border where the flowers 
are desired, or in a seed-bed to be transplanted as need¬ 
ed. Excellent for rock-work, baskets, etc. Treatment 
like the Portulaca, which it resembles in many respects. 
Flowers cup-formed, something like those of the Morn¬ 
ing Glory.

Hispanica, large-flowered; very fine; one fopt, 5 
Fontanesiana, much like N. Hispanica, but 
blooms two weeks earlier,. ... 5 
NEMOPHILA. 
The Nemophilas are pretty, delicate, hardy annuals. 
The flowers arc mainly blue and white. They do best 
if sown in a frame and transplanted early, as the hot sun 
injures the flowers ; but do finely all summer, if planted 
in a rather cool, shaded place. Set about six inches 
apart. A few plants set early among spring flowering 
bulbs in Autumn, or seeds scattered over the beds, will 
give a good account of themselves in early spring. 
Nemophila, mixed varieties,. e 
NIEREMBERGIA. 
The Nierembcrgias have whitish flowers, tinted with 
lilac, with a deep purplish lilac blotch in the center. 
Tender perennials, suitable for house culture, or may be 
treated as tender annuals. For baskets, vases, etc., we 
cannot recommend them too highly. Plants slender, with 
abundance of flowers, and almost perpetually in bloom. 
Nierembergia gracilis, plant very branching, 
spreading; fine for pots, or the border, . ... 10 
frutescens, taller and of more erect habit than 
preceding, with flowers larger and more open, 10 
OBELISCARI A. 
A 
The Obeliscarias are coarse plants with showy flowers. 
The ray flowers are of a rich velvety crimson, edged 
with yellow. The central cone, or disk, is brown until 
the florets expand, and then is bright yellow. Flowers 
on long stems, plants eighteen inches in height. It re- 
| sembles somewhat the wild flower of our meadows, 
j Rudbeckia hirta, or Cone Flower. 
Obeliscaria pulcherrima,. 5

nual, neat in habit, branching, about eighteen inches in
