This Lobelia suffers from a kind of rust, which fastens on the main fleshy roots when the plants are at rest, and rots them.
Pratia - P. angulata is a pretty plant for the rock garden, creeping over the soil like the Fruiting Duckweed; the flowers white, and like a dwarf Lobelia, numerous in autumn, giving place to violet-colored berries about the size of Peas.
Certain herbs such as lobelia, ephedra and others with strong side effects are restricted to licensed, trained herbalists only.

The Alternantheras, Amaranthuses, Iresines and Coleus Verschaffelti furnish high and warm colours; while Pyrethrum Parthenium aureum yields greenish-yellow; Thymus citriodorus aureus, yellowish; Mesembryanthemum cordifolium variegatum, creamy yellow; Centaureas and others, white; Lobelia Erinus, blue; and the succulent Echeverias and Sempervivums, glaucous rosettes, which last add much to the general effect.
Frequently the leaves powdered together with equal quantities of the powdered leaves of the Cannabis Indica and lobelia mixed with potassium nitrate are burned in an open dish.
The stamens may cohere by their anthers, and become syngenesious, as in composite flowers, and in lobelia, jasione, &c.
