Dear all,

A few more plant IDs if you'd be so kind....

Some of these I want to get rid of, others I just want to know what they
are. Sorry - I don't know much about plants....

Photos are he

The first one is two plants growing in a bed. One with coarse leaves, the
other with fine leaves and little white flowers. OK - there's more than 2
different plants growing there, but 2 main ones....

Next up is a big tall gangly thing that looks as if it's about to flower.
Currently the flower tips are about 5 feet high.

For your pleasure, a thistly/ferny looking plant growing well in the rockery
(growing so well, you can't see any rocks....)

Next suspect is a horrible looking thing. Kind of hempy looking long
fingered leaves and an almost segmented looking main stem. Sickly light
green flower heads, but never seems to actually flower. This is quite
invasive, but is pulled up easily.

This one is an almost cactussy looking thing. Thick leaves, almost dusty
green in colour.

Finally, a lovely big purple flowering tree/bush/thing. This looks
spectacular in is about 10 feet tall.

Well - any help gratefully received. I have an RHS plant encyclopedia, but
can seem to identify anything from it - all the pictures show flowers, and
none of these plants have any (apart from the purple tree/bush)..... Is
there an online resource anyone knows of to identify plants just from their
leaves and shape ?
