Hippeastrum aulicum  una specie del sud del Brasile (in particolare

                                                                                                                                                                                     della zona di Sao Paulo).

 

                                                                                                                                          E' una specie a fioritura invernale, rustica all'aperto

                                                                                                                                          nell'Italia meridionale sulla fascia costiera. I fiori possono

                                                                                                                                          essere danneggiati dal gelo, se non protetti. Di norma è

                                                                                                                                          sempreverde, ma le piante hanno un periodo di riposo in

                                                                                                                                          estate e possono perdere le foglie, se innaffiate poco. Queste 

                                                                                                                                          riappaiono in ottobre con le prime piogge, mentre i fusti fioriferi

                                                                                                                                          spuntano a fine novembre per sbocciare nel periodo natalizio.

                                                                                                                                          La coltivazione è alquanto semplice, necessitano di un substrato

                                                                                                                                          ricco di humus (è una specie di foresta) con il giusto drenaggio,

                                                                                                                                          ma a differenza degli ibridi questa specie non necessita di

                                                                                                                                          forzatura per fiorire in inverno.

                                                                                                                                                         Hippeastrum vittatum : specie di origine andina (Perù, Ecuador).

                                                                                                                                          Si tratta di una specie generalmente decidua, con fiori di colore 

                                                                                                                                          piuttosto variabile. E' uno dei principali progenitori degli ibridi a

                                                                                                                                          grandi fiori oggi in commercio. Di facile coltura, ma difficile

                                                                                                                                          reperimento.

 

                                                                                                                   Hippeastrum x johnsonii : uno dei più antichi ibridi (H.reginae x H.vittatum ).

                                                                                                                                          Viene ancora occasionalmente coltivato. E' caratterizzato da fiori

                                                                                                                                          delicatamente profumati in tarda primavera e foglie decidue

                                                                                                                                           in inverno, con un margine rossastro se coltivato in pieno sole.

                                                                                                                                           E' considerato uno dei più rustici, capace di sopportare

                                                                                                                                           temperature di diversi gradi sottozero. In piena terra, con gli anni 

                                                                                                                                           si moltiplica  formando esemplari spettacolari. Pianta robusta e

                                                                                                                                           facile, di  notevole longevità.
