Dear Mary Sue , Thank you for your informations , I have not a problem with treatment this bulbs -they grow ( for me ) very easy - I give them the same treatment like my Cacti from the argentian and bolivian andes - because they grow on the same locations . This plants grow succsessfull and flowering quick raised from seed . A problem ( for me ) is more the treatment of the wintergrowing bulbs . I will send soon some pictures more from the Andes ( if Susan have time to help me ) . I try in this time to send a E- mail to John Bryan - but all my mails come back ( Mail delivery failed ) , has anybody a idea what is wrong ? Many greetings from Germany Hans
