In other cases , they ’ve been upgraded in meaningful ways that improve the gardening experience — good habit , farseeing flush meter , raise disease resistance . Before you swear off new plant life forever , consider these classical climb .

Expect the same vibrant red flowers on a more compact model

Classic:‘Lord Baltimore’ hardy hibiscus

Hibiscus‘Lord Baltimore ’

Zones:5–9

Upgrade:‘Cranberry Crush’ hibiscus

Hibiscus‘Cranberry Crush ’

Zones:4–9

Size:4 feet tall and wide

Conditions : Full sun ; medium soil

The vivacious red salad days and prolific flower show of ‘ Lord Baltimore ’ hibiscus have wooed gardener since the introduction of the variety in 1955 . I still find specs for that plant at 4 feet marvelous and wide , but my experience puts it more toward 6 animal foot tall and all-inclusive with an uncomfortably open habit . Proactive pruning in early summer can maintain the size and shape without significantly delay the bloom show , but if I leave and prune by and by I can sacrifice more than a few weeks of the floral presentation . ‘ Cranberry Crush ’ hibiscus maxes out at a more manageable sizing . The tighter internode make for a denser plant and an even more telling flower show as well . If red is n’t your thing , check out the other 11 cultivars in the Summerific ® series , each as garden - worthy as the one before it .

A beefy Russian sage that won’t split midway through the party

Classic:Russian sage

Perovskia atriplicifolia

Upgrade: ‘CrazyBlue’ Russian sage

Perovskia‘CrazyBlue ’

Size:2 invertebrate foot tall and broad

weather condition : Full Sunday ; dry to medium soil

Russian salvia make its spot as a classic by flourishing in the heat and drouth of summer without batting an middle . Its silverish green foliation is stunning , but when the purply blue efflorescence show outset in midsummer , wow ! Unfortunately , in the rich soil of many gardens , it ’s not uncommon to regain the whole 5 - foot - grandiloquent - and - wide sweetheart split overt and waste one’s time about unattractively even without a electrical storm . Several dwarf varieties have been release that do n’t open up but that also do n’t have the oomph I lie with about the specie . ‘ CrazyBlue ’ is bigger than the dwarf varieties but smaller than metal money . It begins flower two week before than most Russian sages , and it does n’t fall asunder in late summertime even in a thunderstorm .

Blight and leaf miners are no problem for this naturally resistant evergreen

Classic:Boxwood

genus Buxus sempervirensand cvs .

Zones:5–8

Upgrade:NewGen Independence®boxwood

Buxus‘SB108 ’

Size:3 feet tall and all-inclusive

circumstance : Full sun to full shade ; moist , well - drained soil

Boxwoods are the small ignominious dress of the horticulture world ( they go with everything ) , but if asked about Turkish boxwood change , most gardener would likely only come back American box ( B. sempervirens ) and/or English boxwood ( B. sempervirens‘Suffruticosa ’ ) . There are scads of lesser - known selection that -offer different shapes , sizes , colors , and now problem - lick performance in the landscape painting as well . English boxwood , beloved for tight hedging and posh institution plantings , is very susceptible to boxwood blight , among other things . At 3 pes tall and panoptic in 15 years , NewGen Independence ® is similar in size and shape to English boxwood but is naturally repellent to both boxwood blight and box foliage miners . Where English Turkish boxwood involve some ghost , NewGen Independence ® is evenly happy in full sunshine to full shade .

A sedge for nearly every condition imaginable

Classic:Evercolor®Everest Japanese sedge

Carex oshimensis‘CarFit01 ’

Upgrade:Feather Falls™ sedge

Carex‘ETCRX01 ’

Size:12 to 18 inches marvellous and 24 to 36 inch wide

shape : Full Sunday to full shade ; moist to dry out stain

Evercolor ® Everest Japanese sedge can be classified as a fairly raw classic itself at just over a decennary old . Its livid variegation is so clear , its 10 - inch - tall mound of foliage so soft , and its ground performance so solid that it quickly became a staple . Then come Feather Falls ™ , a beautiful beast that eat its predecessor for breakfast . Like Evercolor ® Everest , Feather Falls ™ has arching white - and - green - striped leaves and a clumping riding habit , but it is two to three time bigger and even more graceful . I ’ve seek it in sun and shade , smashed and dry , in the ground and in containers , but I have n’t found its demarcation line yet .

A heuchera with a heartier disposition

Classic:‘Palace Purple’ heuchera

Heuchera’Palace Purple ’

Upgrade:Northern Exposure™ Black heuchera

Heuchera‘TNHEUNB ’

Size:10 inch tall and 28 inches wide

Conditions : fond to full subtlety ; moist , well - drained soil

‘ Palace Purple ’ heuchera was such a breakthrough upon its release that the Perennial Plant Association select it as the second - ever Perennial Plant of the Year ® in 1991 . Unfortunately , its genetics have roam over time , due in part to seedling variability , so the plant you find for sale now as ‘ PalacePurple ’ is n’t the same as it once was . NorthernExposure ™ Black may not go like a honest alternate due to colouring differences , but ‘ Palace Purple ’ is n’t as purple as its name imply , and Northern Exposure ™ Black is n’t as black . Bred to be more cold audacious , the Northern Exposure ™ series turns out to be incredibly large-minded of heat and humidness as well . Northern Exposure ™ Black heuchera also wield besotted clay admirably — which is a demise knell for many Heuchera .

Vivid™ Bright Light dianthus

Upgrade:Vivid™ Bright Light dianthus

Dianthus‘Uribest52 ’

Size:8 to 10 inch tall and 14 inches wide

status : Full sunshine ; well - enfeeble ground

For many years , Firewitch dianthus was the cultivar by which all others were measured . It ’s reliable , just , and has intensely fragrant , neon pink efflorescence over dusty blue foliage in late spring . Vivid ™ Bright Light raises that saloon with a flower show beginning in midspring — earlier than Firewitch — and keep flower powerful through the hot summertime nights into spill . It forge a compact mound of dispirited - green foliage , and the tall flower stem are sturdy enough that they do n’t fall flat . A midsummer shearing is n’t necessary to keep the flower show going , but it does remove the accumulated spent blossom stems , which are so numerous that they can fool you into thinking the blue - gullible foliage has turned browned .

Powdery mildew? Not on this new phlox

Phlox paniculata‘David ’

Zones:4–8

Strong electric resistance to powdery mildew help ‘ David ’ garden phlox originate to classic status and win the Perennial Plant of the Year ® honour in 2002 . However , it has become difficult to find in recent years , and in the plant test conduct at my workplace , it seemed to have turn a loss much of its mildew resistance . Enter ‘ Fashionably Early Crystal ’ phlox . As an interspecific cross , it convey some of the best attributes of other specie , such as sooner blooming ( two or more week before anyP. paniculata ) andoutstanding resistance to powdery mildew . We had it in our test for three year before date any mildew , and even then it was slight . It ’s a just bit shorter than the 4 - foot - tall ‘ David ’ , but the earlier blossom sentence and increase mold resistance offer plentiful compensation .

Same graceful appearance without the invasive tendency

Classic:‘Gracillimus’ miscanthus

Miscanthus sinensis‘Gracillimus ’

Upgrade:Scout™ miscanthus

Miscanthus sinensis‘Tift M77 ’

Size:6 feet tall and 3 feet wide

It does n’t get disease and the deer do n’t consume it , so it ’s an gentle pick for a plant life - it - and - leave - it perennial in full sun . But as many of us have come to realize , miscanthus has a reseeding job . In many parts of the nation , this has become a major proceeds . The come are break up by wind , stand for they can — and do — go impressive distances beyond your garden borders . talent scout ™ miscanthus put up a very similar look to ‘ Gracillimus ’ , but it ’s nonfertile , so you’re able to constitute it in in effect sense of right and wrong . Topping out at 6 feet tall before efflorescence , it ’s about a fundament shorter than ‘ Gracillimus ’ , and in our trials it bloomed several week before .
