Floraison
>12h de lumière/jour
📅 Mars – Avril
Floraison déclenchée par les jours longs (>12 h) en mars–avril après la sortie de dormance. Les hampes florales émergent avant les nouvelles feuilles — signe que la dormance a été respectée.
Dormance nécessaire
Dormance hivernale obligatoire de novembre à février. Réduire l'arrosage, maintenir le substrat légèrement humide. Températures nocturnes proches de 0 °C tolérées et bénéfiques.
pH du sol / substrat
Très acide — n'utiliser que tourbe, sphagnum ou substrats acides spécialisés.
Types de substrat (milieu naturel)
Mélange classique : 50 % tourbe de sphaigne blonde non fertilisée + 50 % sable de quartz lavé (0–2 mm). Sphagnum vivant en couverture de surface recommandé. Éviter tout substrat calcaire ou fertilisé.
Hybrides impliquant Sarracenia leucophylla
Sarracenia × aerolata
Natural hybrid from the western Gulf coastal plain where both parents overlap in Alabama and Mississippi. Produces tall pitchers with a pale yellowish reticulated upper section — intermediate between the white top of leucophylla and the plain top of alata.
Sarracenia × excellens
Produces semi-erect pitchers with white reticulated tops and the narrow tube of S. minor. Hooding is intermediate — less than minor but more than leucophylla. Named for its excellent ornamental qualities.
Sarracenia × readii
Natural hybrid producing narrow pitchers with white reticulated tops flushed with red from S. rubra. Very attractive combination. Named in honour of John Read.
Sarracenia × wrigleyana
Rare and unusual natural hybrid combining the white reticulated top of S. leucophylla with the recumbent parrot-hooded form of S. psittacina. Produces semi-recumbent pitchers with a partially hooded white top. Named in honour of Wilfrid Wrigley.
Sarracenia × mitchelliana
Attractive hybrid combining the recumbent purplish body of S. purpurea with the white reticulated top of S. leucophylla. One of the showiest natural hybrids. Named in honour of John Mitchell.
Sarracenia × moorei
Tall, stately hybrid combining the height of S. flava with the white reticulated top of S. leucophylla. One of the most ornamental natural hybrids. Variable — some forms tend toward flava, others toward leucophylla. Named in honour of Thomas Moore.
Sarracenia alata × leucophylla
S. × moorei (alata form) — where ranges overlap in Alabama and Mississippi Gulf coast. Pale yellowish reticulated top.
Sarracenia flava × leucophylla
Naturally occurring where ranges overlap in Alabama and the Florida panhandle. Intermediate yellow-white reticulated tops. Extremely variable.
Sarracenia purpurea × leucophylla
Attractive hybrid combining the recumbent purplish body of S. purpurea with the white reticulated top of S. leucophylla.
Sarracenia rubra × leucophylla
Natural hybrid producing narrow pitchers with white reticulated tops flushed with red. Very attractive.
