Searching through the posts, seems a few of you have been growing this for a year or so now. What do you think? Like gardengal, wasn't predisposed to like Pistachio, but find myself thoroughly intrigued by its charms in person. You can tell - one followed me home from Lowes in a large 2.25 gallon pot for $27 with the Forever & Ever label.
The "red" at this point is more a rosy pink with coral tones - not what I'd tag red at all. The "lime" green is what I think of as "new leaf" green or "Spring green", not approaching lime or chartreuse as some of the growers' photos show. The opening buds are pale green with the rosy coral pink radiating from the center & ribboning the edges. One of the heads is developing a lavender pincushion center. Expecting the coloration to deepen as advertised as the blooms age, but the colorway is currently much softer than anticipated & quite fetching with pink & coral roses blooming nearby. Like all these chameleons, Pistachio's coloring once established in acidic soil here a mystery unsolved till time tells.
Most impressive is the number of blooms unfolding - no less than 2 dozen, with as many more buds already swelling. Tiny buds uncounted just beginning to show on stem & branch growth at every node. Never seen a mophead this young so full of vitality, so eager to grow & bloom. Been sitting out in full sun the last week, daytime temps peaking between 70 & 90, without the slightest sign of wilt, fresh as the proverbial daisy. High hopes spinning here...
Previously released in Europe as Schloss Wackerbarth, can understand why its been renamed Pistachio here & Glam Rock in the UK, though Horwack is its registration name. Seems Forever & Ever as well as Ball under its Next Generation (Next Gen) line are the licensees in the US. Advertised as growing 3-4 x 3-5', reblooming (blooming on old & new growth) from June to October (till frost?) & hardy to zone 5.
So tell me the skinny - what's not to like?
