The names I have written in Capital letters are the cultivar name, while most of the names you have given are the trademark or marketing name. Annabelle is the cultivar name, and is also used for marketing since unlike many of the others, it is reasonably easy to remember. It is only relatively recently that plants have been patented under one name that often is not something that trips off the tongue, though it may contain some indication of the breeder's name, and then sold under a trademark.

'Geoffrey Chadbund' (not Chadbury) is also known as 'Möwe'. Like Blaumeise, It is also part of the Teller series, bred in Switzerland in the early 60's, all lacecaps and all named after birds. ('Möwe' translates to seagull).

Wedding Gown is the tradename for 'Dancing Snow', part of the Double Delights series.

White Wave is officially 'Mariesii Grandiflora'

Ayesha has several alternate names : Uzu Ajisai, Silver Slipper and Flieder

Pink Sensation is the tradename for 'Agrihydravijf'

Peacock is the tradename for 'Zulu' (part of the Onyx series). Zebra is also part of the Onyx series but Zebra is both the tradename and the patented cultivar name.

There are a number of hydrangeas with Mariesii as part of the name: Mariesii, Mariesii Perfecta, Mariesii Variegata, Mariesii Lilacina and Mariesii Grandiflora.

Tiny Tuff Stuff is the tradename for Hydrangea serrata 'MAK20'

Abracadabra is the tradename for 'Horabstra'

'Blaumeise' is also part of the Teller series and is translated to English as Blue Tit or Blue Titmouse. Also known as Teller Blue, Blue Sky or Armore

Magical Flame is the tradename for Hydrangea paniculata 'Bokratorch'

The Gatsby series are a collection of oakleaf hydrangeas bred by Douglas and Brenda Hill of Cleveland, Alabama. They are all tradenames.......each has a patented cultivar name as well.

Just a note: in correct plant nomenclature, cultivar or patented names are always presented in single quotes.......tradenames are not.
