This is a giant form of Tillandsia pruinosa from Colombia. It is like the smaller or regular forms except that it is larger and does not color up at anthesis as some forms do. It grows to nearly 12 inches tall with a thick base. It might resemble a slightly more slender Tillandsia seleriana due to its size but is a pruinosa for sure. Up right leaves and a bulbous base, all covered with heavy trichomes. Nice.
