AGERATUM - "Floss-Flower" - While for practical purposes it is possible to treat not a few perennial plants as Annuals, it is also possible to so treat some Annuals that to all intents they become Perennials. Such is the "art that doth mend Nature, change it rather." The Ageratums are mostly Half-hardy Annuals, natives of Central and South America, but if they are not allowed to ripen seeds (and this they rarely do in our climate), they may be propagated from cuttings year after year, the stock plants being lifted and potted in the Autumn and kept in a Greenhouse during the Winter. Early in the year these plants begin to grow freely and provide a quantity of cuttings that may be rooted easily in sandy soil in a temperature of from 60° to 70°. It is by this means that the specially dwarf strains are frequently cultivated for Summer bedding, but so well are many of the best forms fixed, that seed-raised stocks show little variation in height and even less in the colour of their flower clusters.

Sowing under glass should take place in February or March, the usual processes of pricking off and hardening off being followed so that sturdy plants are available for planting early in June. A sowing on a warm border early in April will provide excellent material, especially if there is no special need for plants to flower at the earliest possible moment.
The parent of the garden race of Ageratums is A. mexicana, a species that grows about 18 inches high, and produces small Composite heads of lilac-blue flowers, borne in dense clusters and in the greatest profusion. Numerous varieties are catalogued - and some of the best are Blue Star, 6 inches, light blue; Imperial Dwarf, 8 inches, deep lavender-blue; Little Dorrit, 6 inches, lavender; Snowflake, 9 inches, white; Swanley Blue, 9 inches, deep blue; Victoria Louise, 6 inches, light blue with whitish centre; and Lavender Band, 5 inches, soft lavender.
