'Sixteen Candles' is a new cultivar that is a dwarf, bushy selection. It bears good-sized flower spikes about 6 inches long for 4 to 6 weeks in mid-summer. It has a sturdy branching habit and does not droop over as 'Hummingbird' can. Many nurseries prefer 'Sixteen Candles to 'Hummingbird' because of its neater, more upright habit.
