Great discussion!

Since I'm fairly new to the Hydrangea scene, I'm really only into macrophylla mopheads and lacecaps.

I just purchased these that I'm very excited about -

Macrophylla Mopheads : 'Konigstein'
'Lemmonhoff'
'Invincible Spirit'
'Nikko Blue'

Macrophylla Lacecaps: 'Rotdrossel'
'Larnath White'

and Involucrata Tama Azisai. and one of my all time fav is Macrophylla mophead 'Sabrina'.

I can't wait to see them all in bloom!

Wow - I guess I have quite a bit!

I do no have 'Konigstein' or 'Lemmonhof' but I have been eyeing them up! I need more high-quality reds/pinks. Invincibelle is actually an H. arborescens so there you go....you didn't know you were into arborescens did you?! I just planted one in the fall so I am looking forward to it blooming this June based on all of the good things I have heard and seen. 'Nikko' is special since it was my (and millions of other people before 'Endless Summer' came out) first hydrangea: definitely a favorite and incredibly dependable; just about the best all around mac after Endless Summer...you will be happy :)

I wish I could have more lacecaps but most of them aren't too keen on growing in 6A/5B. The ones I do have are in big pots and they are awesome, just awesome but big pots are expensive (and so are hydrangeas). I am going to buy one or two Twist-N-Shouts this year but I am super partial to the Teller lacecaps, one look at them and you are hooked ('Nachtigall' is my favorite but I also enjoy 'Blaumeise' and 'Eisvogel' which are nearly identical but 'Nachtigall' has the best leaves of the Tellers in my opinion). It is a total shame that Tellers aren't more cold hardy.

I need an involucrata; thinking about 'Blue Bunny' from Proven Winners just because I am not an involucrata expert whatsoever and need something dependable (I guess you could say "Proven").

My tentative new additions for 2011:
--'Twist-N-Shout' macrophylla lacecap x2
--'Kardinal' macrophylla lacecap (Teller Red) x1
--somehow I always manage another 'Endless Summer' x?
--an involucrata x1
--another quercifolia; thinking 'Little Honey' x1
