Unlike other dahlia's I grow D. imperialis does not appear to go dormant with respect to day length, it wants to grow all year. Only extreme cold will stop it. The canes are not annual, growth begins from the existing canes in the Spring. It is also apparently immune to powdery mildew - another trait it could pass on...

I just went out on my greenhouse balcony to see how mine is doing.
It's still growing new leaves - no buds in view.  This is the first
time I've grown it, so I don't know what to expect.  It is almost 300
cm tall (about 10 feet) but still has 100 cm or so of room before it
touches the glass.
