Reliable here in 5a/b Wisconsin. Beautiful huge blooms, and plant got 4.5' tall and wide. Bigger every year.

Very vigorous hibiscus, and loaded with huge dinner plate sized flowers reliably by August every year. Mine still hasn't been frozen to the ground yet this winter, and it's looking like it won't this year. Last year it grew to 4 feet high, who knows what'll happen this year? The base is getting very large around, it's more like a tree now.

This is an interesting plant. First, I never thought any hibiscus would survive in canada, let alone, here. Second, I bought this labeled as "Hibiscus Syriacus "Luna Red" from home depot last year. I found out that it isnt Syriacus, but Moscheutos ( why they do that ill never know).

My city is usualy regarded as zone 3a but when you break it down, there are narrow bands or warmer zones, the closer to the lake you go. Im lucky enough to be on the border of the warmest zone ( zone say zone 5a!!) and the one next ( 4b) and to get a relitivly reliable deep snow pack ( usualy 3 feet).

This Hibiscus managed to survive here, and is growing like a weed!. I noticed it coming back from the roots a few days ago, after a sort of weird spring ( sort of cool and wet,... read more

Have some different ones from years ago so I had to add these to my collection.. I obtained them from the local Home Depot in 2010 and so far this year I am getting the new shoots coming up the first week of June.. Looks good so far. I have mine surrounded by cages I make using the vinyl coated garden fencing to help them stay up once the flowers arrive which I find is a big help.

This is new series of hibiscus...I added it was Drought-tolerant; suitable for xeriscaping only after it becomes established...This hibiscus grow about 2' tall and 2' wide..with massive flowers from 6 to 7 inches across...Luna is shorter so is great for mass.It's ideal for perennial borders, as hedging and in pots.These plants are heavy feeders,double up on feeding if blooming slows or foliage begins to show yellow.
