Usages médicinaux

• Cardiac, stomachic [61].

Culture

• Succeeds in most soils[175] but it prefers a light very well-drained porous soil with plenty of leaf-mould [200].
• Requires plenty of moisture during the growing season but it needs to be kept dry in the winter [1, 200].
• Another report says that it is drought resistant when established [190].
• It only flowers freely when growing in a very sunny position [175].
• Plants succeed in maritime gardens [233].
• Plants are probably hardy to about -15°c[187], but are best if given a good mulch should temperatures lower than -5°c occur [200].
• Some plants growing in Essex have their leaves killed by the first frosts of the autumn but the clumps are unharmed [190].
• Hybridizes very freely with other members of this genus - some botanists say there is only one very variable species of Agapanthus [200].
• A number of named varieties have been selected for their ornamental value [187].
• Les plantes ne semblent pas attaquées par les lapins [233].
• The flowering stems lean towards the sun [175].

Propagation

• Seed - best sown in a greenhouse as soon as it is ripe[200], it can also be sown in a greenhouse in March/April [133].
• The seed usually germinates in 1 - 3 months at 18°c[133], do not sow it too thickly so that it is possible to grow the seedlings on in their pot without disturbing them for their first year of growth .
• Give occasional liquid feeds to make sure they do not become nutrient deficient .
• Divide the seedlings up into individual pots in the spring following germination, grow them on for a further year in the greenhouse and then plant them out into their permanent positions in late spring or early summer .
• Seedlings take 2 - 3 years to flower [133].
• Division of offsets in April/May .
• Do not move plants between October and March [175].
• Division is very easy in the growing season, the divisions can be planed straight out into their permanent positions if required .
