Comparing Tillandsia Ionantha varieties — notes from growing several

I've grown several varieties within the Tillandsia Ionantha family and have some observations to share. surprisingly tough once watering rhythm is established varies noticeably between them, more than catalogue descriptions suggest. The care fundamentals are shared — misting more frequently in hot dry indoor conditions applies across all of them.

bleaching and burning from direct summer sun affects some more than others, particularly in adverse conditions. I grow mine in a glass globe or terrarium with open ventilation which works well for most varieties. most vigorous growth in warm humid summer months is the clearest moment of differentiation between varieties — that's when the character of each comes through. Worth growing a few side by side if you have the space.
