While searching on the net came across Penning's Hippeastrum Assortment.
I've been on the site before but to my great delight found it updated and new varieties added. I was thrilled to find 'Barbados' and 'Diva' there too for those two were amongst my newest acquirements.
'Maestro' and 'Twinkle Star' oh how could I get them?! RC are you reading this...!!
