2 Identifications please. The first (with blue flower) is quite tall - about 3 - 4 ft. I've probably planted it myself but the label has gone awol.
The second one (long grass) is quite attractive but became quite invasive last year. I thought I'd cleared it all but obviously not! I'd be happy to leave it if it wouldn't spread so much.
Thanks a lot.

first one is alkanet, a native wild flower related to borage. can be invasive.
second looks like one of the carex genus but may be wrong.

Spot on! Just looked them both up on the net and yes, the first one is Alkanet (Borage) and the second one is Pendulous Sedge. Thank you so much for that.

Carex pendula is the bottom one...a complete garden thug

Carex pendula, Never been allowed to set seed in this garden, but still we get plants coming up every year. Get rid as soon as possible.

your welcome! my spelling abit wrong though!

Thanks again to everyone. Yes, I think I'll get rid of the Carex Pendula - which seems a shame as it really is quite attractive.

Previous question
first one a member of the borage family, and second one looks like pendulums sedge i may be corrected on both but i think i might be close with both.
