Half Hardy Annual
Blue. Flowers August.
A rather tender half hard annual of six species,
which may be raised under glass, and planted out
where it is to flower.
It is safer to grow it altogether as a pot plant,
and the beginner in flower-growing from seed may
very well leave it alone until he has made the
acquaintance of most other kinds.
Dwarf varieties are recommended for pots and hanging
baskets are Marine bells (deep blue), silver Bells
(white) and sky bells (light blue)
Tender annuals of the Nightshade family and native
Browallia americana (syn. Browallia demissa and Browallia elata) reaches
about one foot with oval leaves two inches long,
and tubular flowers, half an inch long and half
an inch across the mouth, of blue or violet colouring
borne in the leaf axils.
Somewhat similar is Browallia grandiflora (syn. Browallia roezlii),
two feet, with smooth green leaves and five-lobed
flowers of bright sky-blue with yellow calyx tubes.
Being somewhat tender and often grown as greenhouse
plants, these delightful species may quite easily
be grown out of doors if planted out in June from
Seed should be sown under glass in March, the
seedlings pricked off singly into pots and nursed
under glass until planted outdoors in their flowering
quarters in June. They should enjoy full sun and
the soil must be well drained.
Propagation is from seed.
The flowering season is from midsummer onwards.
