Last summer I became fascinated with pictures of stunning Hardy Hibiscus (Rose Mallow) totally covered in huge blooms. My search began to find the best hardy hibiscus for my own garden. Searching the internet and joining a hardy hibiscus group on social media led to my obsession with these beauties. If you like eye catching ‘stop in your tracks’ ‘gotta have it’ blooms, I think you will appreciate the findings of my research.
The perennial Hibiscus moscheutos and its hybrids are hardy in USDA Zones 4 to 9. They die back to the ground each winter and sprout from the roots in May. Blooms, ranging from 5- to 12-inches, are displayedmid- summer to fall.
Tall cultivars are 4 – 5 feet, medium 3 – 4 feet, and short 2 – 3 feet reaching full size in three years. Width may be more or less than the height.
Current trend is short or medium compact cultivars with flowers produced along the entire length of the stem, not just the tip.
Hardy Hibiscus requires well-drained, enriched soil, consistently moist, but not waterlogged, and at least 6 to 8 hours of sunlight. Spacing requirements differ for each cultivar. Cultivars should be pruned to about 3” early spring.
Luna and Disco Belle Series and other compact cultivars do well in containers. We will look at a few current favorites in each color category.
White
There are several choices of solid white blooms. ‘Blue River II’ is a tall cultivar with 10” blooms. The 6” blooms of ‘Marshmallow Moon’ are known for their resilience. The slightly cupped 7” blooms of Summerific ‘Cookies and Cream’ contrast its purple- black foliage.
If you prefer white with red eyes, take a look at ‘Disco Belle White’, ‘Luna White’, Summerific ‘Angel Eyes’, Summerific ‘Mocha Moon’, or Summerific ‘French Vanilla’, a near white with ruffled edges.
The 7” bloom of Summerific ‘Ballet Slippers’ (med) is dainty white, slightly ruffled petals with a seductive pink blush, accompanied by a deep red eye.
Purple
‘Lilac Crush,’ (tall), ‘Berry Awesome’ (med), and ‘Berrylicious’ (med), all Summerific series, are various shades of purple.
Pink
Pinks are always popular. Summerific ‘Edge of Night’ (med) has 8” blooms, with overlapping bubblegum pink petals and dark pink veining, against jet black foliage. ‘Watermelon Ruffles’ (tall) has 7” magenta blooms and heavily ruffled petals, a texture you are tempted to reach out and touch.
More popular pinks are ‘Luna Pink Swirl’, ‘Summer Carnival’, ‘Kopper King’, ‘Moy Grande’, and the following Summerific cultivars: ‘Evening Rose’, ‘Airbrush Effect’, ‘All Eyes on Me’ and ‘Candy Crush’.
Red
My favorites are the true deep reds. Scarlet blooms of ‘Midnight Marvel’ (tall) are set against wine-purple foliage. Summerific ‘Holy Grail’ (Med) boasts deep red textured blooms set against near black foliage, with a tight, dense growth habit. Both create a stunning display with 9” blooms.
Additional reds are ‘Luna Red’, ‘Mars Madness’ , ‘Head over Heals ‘Desire’, ‘Carousel Red Wine’, ‘Carousel Giant Red’, ‘Lord Baltimore’, ‘Big Red’ and Summerific ‘Valentine’s Crush.’
Show stoppers
Here are some white and pink combinations of Summerific cultivars. Many of them are show-stoppers.
‘Spinderella’ (tall) features 8” white blooms with pink accented edges forming a pinwheel with a dark red eye. ‘Perfect Storm’, although short in stature, begs for attention with 7-8” blush pink blooms, and a brilliant red eye.
‘Starry Starry Night’ (med) features 8” blooms with white overlapping and turning petals marked and streaked with shades of pink. Foliage is nearly black.
‘Cherry Choco Latte’ (med) features 9” pinkblushed white blooms with intense deep pink veins and a dark cherry-red eye. Foliage is olive green.
Blooms of ‘Dark Mystery’ (tall) are similar colors, but a different pattern. Foliage is wine-purple.
New colors
New colors have arrived, never before seen in hardy hibiscus — ‘Amaretto’ coral-salmon, ‘Ambrosia’, fuchsia with white eye, ‘Bleu Brulee’, obviously blue, and more, part of the Summer Spice series.
These hybrids of Texas A& M AgriLife deserve a separate article, hopefully to be published later this year.
