Convolvulus minor. - Dwarf Convolvulus. - A beautiful hardy annual, easily cultivated, affording a large mass of beauty from July to October. The plant spreads out much in every direction from the centre, so that a bed of them, with the plants two feet distant from each other, will interlock. It is not exceeded in elegance by any plant, when profusely covered with blue and yellow flowers, which open in the morning, and continue the greater part of the day, if the sun is not powerfully hot, in which case they often fade by noon. The seed should be sown in April.

C. major. - Morning Glory. - A well-known annual, of easy culture, and suitable for covering arbors or shading windows, consisting of many varieties, as white, rose, purple, and striped.
