My Aloe 'Doran Black' has produced its single bloom stalk. It is not uncommon for it to have a stalk several times throughout the year. Its variegated leafs are quite attractive (though mine still show damage from last year's golf ball-sized hail).
The 1.5 foot stalk is quite thin and I have found it best to give it additional support, otherwise wind or rain will cause it to snap.
The stalk is crowned by a spread of small red flowers that will, at best, only barely open at their tip, but are quite attractive anyway.
