Tillandsia reuteri
Peter Tristram 12/11, approx 70cm diam.
Chris Larson 12/14. From Amazonian side of Andes in Nth Peru ~1800m.

Chris Larson 01/16 ... "This plant has been in the kitchen for months. It lasts a good while. I have had one in the greenhouse unheated over the last winter so it is hardy.
I posted a pic of this plant last year which did not have this colour at that time. It can, like other Peruvian tillandsias, continue to spike over 2 seasons. This is what happened to the one that produced the dead spike on the bench. The latest flowering plant here has produced a flower at a much smaller size, and therefore it has not flowered with as many branches or as large as some others I’ve flowered previously."

Peter Tristram ... "One of the more recently introduced tank species is T. reuteri. These came from either Heidelberg BG in Germany (Heid on my tags) like this clone, or as seedlings that I purchased from Jeff Kent (JK on my tags) in 2012. It’s a lovely species and quite hardy too."
Geoff Beech ... "T. reuteri getting by in Melbourne but it doesn’t like the colder months."
Peter Tristram ... "Despite having to tough out winter in Victoria, your plant looks great. When mine bloom over summer, like this hot one, there isn’t the intensity of colour unfortunately."
Bruce Dunstan 12/21
Chris Larson ... "Lovely, Bruce. Very slow here. But well worth the wait.
Those pale tones contrasting with the stronger colours at the tips are even better in real life.
One thing I'd like to bring up with culture: I have this same issue with the browning of the leaf ends - which I have always associated with a lack of nutrient, so the lower leaves are utilised by the plant - at least, I assume this when growing other plants. However, whichever method I grow T. reuteri under - pot vs mounted - high fert vs low fert - this still happens. There are a few other large tank - mainly cliff dwellers - which all do the same.
Anyone with any ideas on how to counter this? Or know the reason why this happens?"
Bruce Dunstan ... "Peter Paroz suggested the tip dying off on T. australis may be linked to a defficiency in Calcium."

T. reuteri is similar in habit to a dwarf form of T. glauca found by Rauh in North Peru. It differs in the sharp, acuminate, almost bent hooked floral bract. Is also related to T. stenoura.
