H. macrophylla Next Generation Almost Heaven - Ball Hort

size: 2-3', zones 5-9

"A compact, comtinuously blooming mophead variety. Begins to bloom in early summer and carries on right through until frost"

H. macrophylla Peppermint Swirl - Van Essen

size: 3x3', zone 5-9

"Sensational ornamental shrubs with dazzling blooms will jazz up your landscape. Pink or blue mophead flowers, displaying a very unique “peppermint candy” variegation."

H. macrophylla Blarney Stone ('SMHMSV') - Proven Winners

size: 2-3', zones 5-9

"Soft pink or blue flowers look beautiful against the chartreuse and green variegated foliage, and appear every year on this reliable reblooming hydrangea. Soil pH will affect flower color. Fresh and green as the Emerald Isle, its variegated foliage is a first for reblooming hydrangeas. Add it to gardens for months of beautiful color."

H. arborescens Lime Rickey (SMNHALR) - Proven Winners

H. macrophylla Double Hot Pink - Van Essen

size: 2-3x3-5', zones 5-9, reblooming

H. macrophylla Electric Rouge - Van Essen

size: 5x5', zones 5-9, Reblooming

I'm sure all are pretty hardy, except maybe Cabbage Patch.

Those new pink/red ones look fairly promising, as people have had trouble getting things like Maltisse and Red Sensation to work well for them.

And it seems like Blarney Stone might be a good upgrade to Lemon Daddy (for those who continue to have trouble with it).

Also, I continue to be impressed by the work of Tim Wood at Spring Meadow Nurseries as he continues to cross many neat new varieties for Proven Winners (about half of the above work is his).

Later, as I come across more new things, I will post them in this thread. The Japanese have contributed some entries too as of late, although a bit more obscure.

To be continued...

H. paniculata Pillow Talk (SMHPZIND) - Proven Winners / Spring Meadow

Size: 6-8', zone 4-9

"Watch a delightful parade of color changes as bright lime green flowers mature to pure white, then blush with pink as summer progresses. Large, full panicles are held upright on sturdy stems."

H. quercifolia Jetstream (PIIHQ-I) - First Editions / Plant Introductions

Size: 5-6'x4-5', zone 5-8

"A quantum leap in H. quercifolia introductions with dense compact non-flopping habit. The lustrous dark green foliage is resistant to leaf spot and turns a fantastic orange-red in autumn. Flowers held high on strong stems are a beautiful white aging to pink. Classic native flowering shrub for the garden, grouping and massing. Peeling rich tawny-brown bark adds winter interest."

Forever & Ever might soon be marketing 'Black Together' as Midnight Magic. Another Irie hybrid, a US Patent was issued for it in 2013 under the name BTI.

There is a page for the plant on F&E but it's not yet listed in their catalog.
