Dahlias should fit the bill. One caveat is that you have to dig them
up for winter, or buy new tubers each spring. If you divide them
after digging up, you get an exponential growth in the number of
plants each year though.

Strong points of dahlias are that they bloom for months and months,
and offer great variety - there's thousands and thousands of very
different cultivars available. Just search for dahlias on
http://images.google.com/ to get an impression. Also, AFAIK there is
a rather active dahlia society in Colorado, which can be a big
benefit (or, at least you know somebody grows the flowers in your
state... ).



Yeah they're gorgeous. I tried some a few years back and they were
great, but didn't dig them up & they died.

What about zone 4 perennial bulbs that can be planted in spring &
bloom in summer.

Arent Crocus Sativus that way here? And they yield the most expensive
and tasty spice in the world - saffron!

It could be a bit cold for them, aren't they grown around the mediterranean
where summers hot and dry and winters cool and damp?
