There was a little drama getting onto WordPress for Tuesday Treats, but hopefully I’ll get this finished!
The answers to last week’s Tuesday Treats have been added in – they’re here, if you want to check:

It’s time for this week’s mystery plants. See what you make of these.
1
Edited to add: A red hot poker, of course, almost certainly Kniphofia ‘Atlanta’, named for the hotel in Cornwall where it was first found. A very reliable May-flowerer.

2 The pink-flowered shrub
Edited to add: Weigela, believed to bee ‘Bristol Ruby’

3 The orange flowers
Edited to add: Papaver orientale ‘Brilliant’. And it is!

4 The purple flowers
Edited to add: the lovely Allium ‘Purple Sensation’.

5
Edited to add: A Dutch Iris, probably ‘White Magic’

6 Yes, this plant. Also, name the type of inflorescence, for Brownie points.
Edited to add: Arum italicum ssp italicum ‘Marmoratum’. It used to be called Arum italicum ‘Pictum’, which means ‘painted’, like the Picts. ‘Marmoratum’ means ‘marbled’.
The inflorescence – it has a hooded spathe which contains the flowers on a club-like spadix. If you got that, have a nice cup of tea and a good sit down.

7 The white flowers in the centre foreground.
Edited to add: Camassia leichtlinii ‘Alba’. Named for Max Leichtlin who founded a botanical garden in Baden-Baden, and specialized in the cultivation and propagation of bulbous plants.

8
Edited to add: Nectaroscordum siculum, the Sicilian honey garlic. ‘Siculum’, unsurprisingly, means ‘of Sicily’, although it ranges across Southern Europe.

Best of luck!
