Bahia Trolliifolia.--This hardy herbaceous perennial will grow in any
kind of soil. It flowers in August, and can be increased by division.
Height, 1 ft.

Balsams.--The seeds of these tender annuals require to be sown in
early spring in a hot-house or a warm frame having a temperature of 65
to 75 degrees. When 2 or 3 in. high, or large enough to handle, prick
off singly into small pots, shade them till they are established, and
re-pot as they advance in strength in a compost of loam, leaf-mould,
sand, and old manure. Give them air when the weather is favourable.
The last shift should be into 24-sized pots. Supply them with an
abundance of liquid manure, admit as much air as possible, and syringe
freely. They must never be allowed to get dry. Secure their stems
firmly to sticks. They will flower in the open early in September.
Height, 1-1/2 ft. to 2 ft.
