Highly ornamental climbers or twining plants, introduced from South America. They are among the most useful of our annual-flowering plants, requiring very little attention and thriving in any soil. For quickly covering arbors or anything which is unsightly, the tall-growing species are not easily surpassed. The dwarf bushy species are excellent for planting as a groundwork among shrubs, or for filling beds in semi-dry situations as they continue to bloom quite late in Summer if the ground is well cultivated and mulched with a top dressing of manure, leaf-mold or other loose fertilizing material.

Sow the seeds, one-quarter of an inch deep, where they are wanted, at any season between the first rains and March in the frostless belt, and as soon as danger from frost is over in other districts. Nasturtiums should not be sown in rich soil as in such they grow too much to leaves and stems, flowering more profusely if their growth is not too strong.

Tropasolum tuberosum, Tropasolum speciosum and other tuberous-rooted species do not seem to take kindly to California, although no good reason has yet been given for their failure; being natives of Chile and the cooler districts of Peru, they ought to do splendidly. They are all handsome climbers and no doubt they will yet give good results when the proper conditions are found for them.
