Which tall flowers bloom after mid summer and are perennial and re-seed?

Question

how long do they bloom for and when exactly?

Thanks for your answers!

Answer 1

cannas are the best flower for your description.

great leaves and some come in lots of colors. ther flowers can also be many colors according to the type of canna. they have dwarf cannas in which the foliage grows to 3 feet and then a large stalk with a flower comes up 4 feet high, but some grow up to 5 feet tall with flowers up to 7 feet high about 2 feet above the foliage.

blooms fom july all the way till the night before frost. blooms are very plentiful with the most occuring in full sun around the month of august.

will come up year after year if temps are above 10 in the winter and kept dry. some get them to survive to 0 by putting a garbage can lid on the area  where the plant was, and then putting lots of leaves on top of the lid.

once the plant dies at frost cut to the ground.

if you live in an area that is colder than this wait till frost and cut the palnt. then dig the bulb up, wash the bulb, and make it dry ans store in a cold area with temps no higher or lower than 50 degrees

Answer 2

verbena bonariensis

very tall and feathery

last in bloom for ages

and...re-seed all over the place!

Answer 3

Depends on where u live.  Some plants that are perennials in some zones are annuals in others....and vice versa.

I like Echinecea ( cone flower ).  It blooms from now until early fall if treated right.  

My Russian Sage still has some color on the plant and blooms from June til August.....

Also.....one of my favorites...Liatris.  A really cool tall plant with brush looking tall blooms.  Check it out.  It's a really cool plant.  

I also plant Obedience Plant.  It blooms in August ( in zone 5....midwest) but looks pretty good beforehand.  

good luck
