Half-hardy annual
THIS beautiful South African annual is remarkable for its floriferous
character, long duration of bloom, and diversity of colour. Since we
introduced it to this country in 1888 it has attained great popularity
as a pot plant for table decoration, and some
of the most resplendent
bedding effects in public parks and gardens have been secured with this
flower.
For an early show of bloom sow in pots or pans in March under glass,
using a compost consisting largely of good fibrous loam, with the
addition of a small proportion of wood ashes. No more heat than
necessary should be used, and when the seedlings are large enough to
handle prick them off and gradually harden for planting out in May.
Other sowings may be made in May and June, and at this period of the
year the seed germinates most quickly in boxes placed in a cool shady
spot out of doors. In early summer seed may also be sown in the open
border, and by thinning to a distance of six or eight inches sturdy
plants will be secured, which will remain in bloom until quite late in
autumn.
For winter and early spring flowering in pots seed should be sown in
August or September. There must be no attempt at forcing, or attenuated
worthless plants will result. A further sowing may be made in January
for blooming in the later spring months.
Like the seed of Verbena, Furze, and some other subjects, the
germination of Nemesia under artificial conditions is somewhat
capricious, but no difficulty will be experienced with open-air sowings.
