Cardinal Flower or South American Devil's Tobaccois a broad
genus with numerous annual to herbaceous perennial species.
Several species have ornamental, bright colored flowers. All
Lobelia species are easily cultivated in any rich, well drained
soil in a preferably sunny spot. They are very robust and adopt
very well to various soil types. Perennial high altitude species
from Chile in South America are reasonably winter hardy in
Central Europe with some extra winter protection (i.e. a dry
mulch layer). Sow the dust like seeds on top of any humus-rich,
well drained, slightly moist soil. Keep pots in a sunny,
protected spot outside. Several species require a cooling period
of several months prior to germination. If these species are
sowed late in the year, they do not germinate before spring in
the following year. Carefully transplant perennial species to
the final spot in the garden as soon as seedlings are strong
enough. All are USDA Climate Zone 6. 50 seeds per package.
