Butterfly bush is a very hardy and woody shrub. It grows at a fairly fast rate if it's happy in it's environment. Ordinary garden soil should be fine. The old fashioned purple butterfly bush is very hardy and drought tolerant and blooms from spring on through late summer in either full sun or part shade. I have several varieties of butterfly bushes and find the yellow butterfly bush is the slowest growing. The old fashioned purple is about 5 years old is about 6-7 feet tall. The yellow is still the same height as when I bought it about 3 years ago. I live in the upper south and prune the butterfly bush in the early spring, about when the forsythia blooms. It seems to produce healthy, long lasting flowers and is a favorite in my garden with butterflies and hummingbirds. I think in good garden conditions, you'll see a moderately fast grower, about 3-4 in diameter, if not more.
The Butterfly bush is Buddleia.
The plant you might be referring to is the Cleome, also known as spider flower. It features tall, upright growth with purple blooms that resemble those of a butterfly bush. Cleome does not have the same arching habit as butterfly bush but can offer a similar pop of color and height in the garden.

The Butterfly Bush or Buddliea does not have to be pruned for repeat flowering but to keep it compact and tidy you can prune it as hard as you like in early spring.
No. The butterfly bush flowers, but only in the right conditions (obviously). It also depends on the type of bush.
