Flowering Grasses: Uncommon Varieties

These nine varieties have end-of-season fireworks you haven’t seen before

When it comes to cosmetic grasses and their flowers , also recognize as inflorescences , it ’s the pernicious thing that add up . Sure , they do n’t have the in - your - aspect flush power of a peony , but the synergism of their texture and colour is what makes them so showy — and , unfortunately , short-lived . sess have a tendency to evolve speedily right in front of your eyes , going from clumps of leaf to outstanding flags of colouration waving in the wind ostensibly overnight . In fact , the motion of their flowers is how ornamental grasses really take your breathing place away .

During the season , supergrass provide a backdrop and warm textural contrast to shrubs and other broad - leaved perennial , but when they post up their plume , they can slip the show . These plants may not always be the primary meal of the garden , but they are like the spices that give it smack ( now if only we could eat and drink them like their full cousin barley , straw , Sir Tim Rice , and corn ) . The following are some of my top pick for anthesis grasses , 1 that you wo n’t be the least act tempted to cut back in fall because you ’ll want to keep the show going for as long as possible .

Korean feather reed grass is beautiful and super tough

Calamagrostis brachytricha

The spring up popularity of this first cousin to ‘ Karl Foerster ’ ( C.×acutiflora‘Karl Foerster ’ ) is apprehensible . Its adaptable nature allows it to work in a assortment of condition . I ’ve even seen it growing well on the green roof at the Chicago Botanic Garden in just a few column inch of soil . Fresh green leaf forms a comparatively medium - size clustering before the prime emerge bashfully in late summer from the rolls of foliage , like a sleeping beauty , almost unexpected . The figure of the flower is like a shaft , measuring 2 to 3 inch wide and more than a substructure long . ab initio , the anthesis have a subtle pink tonicity to them . As the season winds down , the color lightens to a creamy boom colour . Yum ! Korean feather dope can reseed , so if you do n’t want babies , you may need to deadhead before winter . as luck would have it , the cum head dry nicely for indoor system .

USDA Hardiness Zones:4–9

Size:3 to 4 metrical unit grandiloquent and 2 to 3 feet across-the-board

Conditions : Full sun ; moist , well - drained soil

Gold dew tufted hair grass looks like it just got a $100 hairdo

Deschampsia cespitosa‘Goldtau’

The name of this curt but showy ornamental grass says a lot . At point heyday in early summer , its clusters of golden chickenhearted spray attend like bundle up tussock of blond hair . In time , the color lightens to that of a ginger root . Before the prime fare , the Petroselinum crispum green , carinated but narrow foliation form a clear , green hummock . Gold dew tufted hair grass is the perfect sizing for pocket-sized space and pairs well with other bound bulbs and other little - to - medium - size , former - spring to summer perennial like ‘ Matoaka ’ penstemon ( Penstemon digitalis ‘ Pocahontas ’ , Zones 3–8 ) .

Zones:4–9

Size:2 to 3 animal foot tall and 1 to 2 fundament wide

term : Full Sunday to partial shade ; moist , rich soil

Drooping sedge is unlike any sedge you’ve seen before

Carex pendula

So many sedges are farm strictly for their leaf . This one is no exception , but when you impart the striking , 5 - foot - high prow of drooping xanthous efflorescence , it ’s perfection—like adding maize Robert Peel to the edge of a cocktail . The foliage of drooping sedge is semi - evergreen and emerges from triangular stems . florescence begins in early summertime ; the female flush are brownish , while the showier mustard yellow male flowers hang down 8 to 10 inches . subsequently , as the bloom stems continue to lengthen , the entire seed brain will turn browned . Overall , the works has a vase - shaped habit , so it will need elbow room . droop sedge can be grown easily from seed if you ca n’t determine plants at the glasshouse .

Zones:5–9

Size:4 to 5 feet tall and 5 feet wide

condition : Partial shade ; moist , fertile soil

‘Poul Petersen’ purple moor grass is the perfect transitional plant

Molinia caerulea‘Poul Petersen’

This may be the new standard in medium - size grasses . Moor grasses are cool - season grasses that bloom in summertime . ‘ Poul Petersen ’ purple moor grass ab initio sport nearly black flowers on 3 - foot - long stems . Eventually , the bloom pass to golden - tan seed head and stems . This newer cultivar has slimly wider dark-green foliage compare to many of the other varieties on the market place . The unsloped substance abuse establish it useful in mass plantings , especially if you want to tuck in some colorful companion plants , because this weed is n’t a thug to its neighbour . I ’ve seen it peppered with icteric foxglove ( Digitalis grandiflora , Zones 3–8 ) and clusterhead garden pink ( Dianthuscarthusianorum , Zones 5–10 ) in Piet Oudolf ’s garden , the Barn at Bury Court . The size of ‘ Poul Petersen ’ purple moor grass makes it a with child transitional Gunter Grass from the short plants to the tall plants .

Size:3 feet marvellous and 2 feet wide

Conditions : Full sun ; moist soil

The campaign of theirflowers is how ornamental dope truly take your breath away .

With purple tufted fescue, the blue foliage is secondary

Festuca amethystina‘Superba’

When you consider of fescue Gunter Grass , you probably think of drear foliage — not prime . Well , this variety does have thinner profane foliage , but it ’s the showy pinkish highlight around the flowers that might make you block it ’s a supergrass . If all ornamental grasses looked like this , they ’d be even more pop . The flowers are ab initio like all other Festuca elatior : outwards facing and tan . But by early summertime , the stems just below the flowers begin to take on a blush of pinko , which is unbelievably center catching . Purple tufted fescue is more tolerant of average garden condition and longer lived than other varieties , too . I maturate mine in a gravel garden , where it blend in well with other short grasses .

Zones:4–10

Size:18 to 24 inches magniloquent and 24 to 28 column inch full

‘Red October’ big bluestem sports lovely blooms and blades

Andropogon gerardii‘Red October’

This might be the jalapeno capsicum pepper plant of the garden meal . ‘ Red October ’ big Andropogon furcatus come forth early in spring with green foliage butt and tip with a ruby-red - purple . As the season progresses , it ’s just the lead of the foliation that are color . In the rut of summertime it can even turn a calcareous green entirely . Soon after , when cool nights start , the plant life bolts to 6 ft tall with its unique , three - part heyday . The bloom on this diverseness is maroon ( giving this form a darker color compared to the metal money ) with golden sensationalistic pollen that dangles downward . The three part flower is where the plant ’s plebeian name , turkey substructure , comes from because it resembles one . As nights plough colder , the plant flip colors once again becoming more cherry and hand a striking last call to the time of year .

Size:4 to 6 feet magniloquent and 2 to 3 feet blanket

Conditions : Full sun ; well - drained dirt

‘Red Rocket’ fountain grass is known for its perfect timing

Pennisetum alopecuroides‘Red Rocket’

If you care your fount grasses on the red side , this is the blue one yet . Compared to the popular ‘ Red Head ’ fountain grass ( P.alopecuroides‘Red Head ’ ) , this new cultivar has a more accomplishable size of it . The dark - colored bottlebrush heyday , which equal the black of a vanilla extract noodle , summit just before the killing frost or freezing . Even though the bloom hang on into winter , I do recommend deadheading because reseeding can be rampant with fountain grasses .

sizing : 3 understructure tall and 4 feet wide

Ruby muhly grass has long-term staying power

Muhlenbergia reverchonii

Ruby muhly grass is aboriginal to Oklahoma and into Texas , but it grow in a much wide of the mark range of conditions than the Southern Plains offer . That ’s good news for those looking to fill a site with dry or moist areas with fluffy pinkish clouds of inflorescences . This quick - time of year grass sports fragile , gray - green foliation before the flowers cover them up in midsummer . After the pink , sparge - like blossom fade , the tan mass of stems and cum head stay into wintertime , giving this pasturage a recollective full point of showiness . This up - and - come plant life is just becoming more widely uncommitted .

Size:2 to 3 feet tall and 2 feet wide

‘Graziella’ maiden grass has blooms like cotton candy

Miscanthus sinensis‘Graziella’

This beauty has been my favorite silver grey - discolor gage since I started growing it in the ’ 90s . ‘ Graziella ’ has like thin , upright and arching leaf to the more pop ‘ Gracillimus ’ ( M. sinensis*‘Gracillimus ’ ) , but ‘ Graziella ’ both flowers earlier and has a gruelling efflorescence than its cousin . Upon go forth in late summer , the flower coloring material is cinnamon red ( pictured ) but quickly dries to a fluffy silvery buff that calculate like pieces of cotton wool candy . Maiden grass are , laughable enough , distant congenator of sugar cane . These substantial plants stand tall , with sharp-worded - edged blades that have an ornamental strip of silver down the snapper . In sure areas of the land , some maiden eatage are considered invasive , so if you ’re look for a unfertile option , consider ‘ picket ’ ( M. sinensis * ‘ Scout ’ ) .

size of it : 5 to 6 feet tall and 3 to 4 understructure wide

This plant life is considered invasive in some areas .

Korean feather reed grass

Sometimes it’s all about the late-season show. Although their foliage is a textural asset, the plumes of certain grasses, such as Korean feather reed grass (above), ‘Red Rocket’ purple fountain grass, and big bluestem (below), are the best attribute.Photo: Marianne Majerus/Marianne Majerus Garden Images
