Uncommon Pollinator Plants

As more and more of us understand the importance of beneficial  insects, we want to host plants in our gardens which welcome and provide food for all of them, plus bees, butterflies and birds. Here is a short list of lesser known plants which add varied ornamental interest as well as lure many more of the good invertebrates into your garden

ascspeCU500Asclepias speciosa

One of the earliest Butterfly Weeds to bloom, Asclepias speciosa, or Showy Milkweed ,has umbels of white to mauve pink flowers in late spring and early summer, with attractive gray linear foliage. Its flowers are a nectar source for all butterflies and its foliage is food for monarchs.  Asclepias speciosa can grow up to 3’ tall and 1-2’ wide. Native to dry uplands of western N. America, it is drought tolerant. Hardy in zones 3-8.

parinteg500

Parthenium integrifolium

Wild Quinine or American Feverfew is a Missouri native with 8-10” tobacco like basal foliage, and  2-3′ stems bearing clusters of white fuzzy yarrow-like flowers in midsummer. Beneficial wasps and butterflies are often seen hovering over its blossoms. Parthenium integrifolium was grown in years past for its medicinal qualities,  and it makes a nice addition to the dry wild border. Hardy in zones 5-9.

pycmut

Pycnanthemum muticum

Mountain Mint spreads, so think of it as a ground cover for butterflies and bees. Beginning in mid summer and continuing into September,  Pycnanthemum muticum displays showy silvery bracts surrounding a central disk rimmed with tiny pale pink/white flowers. Drought tolerant once established, plants will grow 2-3’ tall and are the first pitstop for my honeybees when they leave the hive. Hardy in zones 5-9.

silphiumfl_500

Silphium perfoliatum

“Cup Plant”, so called because water is held in the reservoir created where the stems pierce through the opposite leaves, provides a watering hole for birds, bees, and butterflies. This Sunflower like plant is useful at the back of a border, where it bears yellow daisies on 4-8’ stems during July and August . I particularly like Silphium perfoliatum’s  green seed heads as cut material for fall arrangements. Hardy in zones 4-8.

stolpp500

Stokesia laevis

Stokes’ Aster is a showy native with 23” double lavender blue daises on 18-24” plants. Plants begin to color in late June and early July and carries into August. Beautiful as it is as a cut flower, you may want to leave the blossoms undisturbed to enjoy the dance of the butterflies above them. Grow Stokesia laevis in average to dry soils. Note: It resents winter wetness. Hardy in zones 4-10.

astptarm500

Aster ptarmicoides (formerly Solidago ptarmicoides, and NOW to be botanically correct: Oligoneuron album)

Formerly White Upland Aster or White Goldenrod depending who you askedbut with its new genus classification,  Oligoneuron,  who knows what to nickname it?  Anyway, we first saw this plant at Wave Hill 20 years ago (labeled as Aster ptarmicoides), where it looked crisp and clean on a hot August day. Years later we were finally able to hunt down a seed source for it and now have it in our garden. Tidy plants have 4-5″ dark green linear leaves, and bear sprays of small papery white asters on 15” stems  in mid-late summer through early fall. Yes to bees and butterflies, plus goldfinches love the seeds! Hardy in zones 3-8.

astlbl500

Symphyotrichum (Aster) laeve

We have grown the strain ‘Bluebird’  of Smooth Aster for years, with  its 1-2” orange yellow centered, clear blue daisies born in September and October.  Symphyotrichum laeve is a plant that is very happy in our mixed borders, self seeding here and there, but is easy to relocate should it pop up somewhere where it is not wanted. Plants grow 2.5-3’ tall and are about 18” wide. Happy in average to dry soil in zones 4-9.

Eucomis comosa ‘Oakhurst’, Hardy Pineapple Lily

eucomis_oakhurstpot500

For the first few years that we grew Pineapple Lilies, we understood that the hardiness range was zones 7-10  for most forms. And that was okay. We would grow it in containers or dig the corms up after a killing frost.

eucomis_oakhurstsq500

Then we heard that some forms of Pineapple  Lily were proving to be quite hardy, especially a purple leaved variety, Eucomis ‘Oakhurst‘.  Not wanting to perpetuate “fake news”, we needed to be sure this was in fact true. Four years ago  we planted several plants in our zone 6A garden in average, well drained soil where they get 6 hours of sun.  ‘Oakhurst’ has not only returned dutifully each year, it has produced offsets as well as viable seed, which have germinated easily giving us many dark leaved progeny. Some folks are even reporting that is equally hardy in zone 5 in  a protected spot.

eucomis_oakhurst500

Eucomis comosa  ‘Oakhurst’s  strap like leaves are an especially dark wine in cooler temperatures, and green up a bit during summer heat. In late July and early August. ‘Oakhurst’ produces spires of pinky white starry blossoms  on 20-24″ stems. Seed heads remain attractive, and you can leave them  for the seed to mature if you like, or remove them to send more energy to the bulbs below ground.

Magnolia ‘Sunsation’

magnolia_sunsation500

I am just smitten with this Magnolia’s nuanced loveliness….chalices of buttery yellow petals infused with plum and pink appear here in early May, waiting for the last frost to come and go.  Yes, it blooms before the leaves unfurl, providing that magic of color against bare wood.

Bred by the late Dr. Augie Kerr, MagnoliaSunsation’ is a hybrid of ‘Elizabeth’ and ‘Woodsman’, and is considered hardy in zones 4-9. ‘Sunsation’ blooms precociously … very young plants try to put on a show which pleases those of us who tend to be impatient.  Her form is upright and pyramidal, reaching heights of 25-30′.

Grow ‘Sunsation‘ in a rich well drained soil in sun or partial shade.

Hygge…& Celebrating Winter’s Gifts

chokecherries2

Aronia arbutifolia “Brilliantissima’ with the first snowfall

Last week’s arctic blast brought temperatures in the single digits and truly announced that winter had arrived. Ready or not, garden chores were a wrap and the time had come for most of us to give ourselves permission to chill…indoors! 

We gardeners are naturally inclined to follow the rhythm of the seasons, and the shorter days of winter are a check for us to slow down and restore our energies. You, like I, may resist going into full hibernation mode, but why not take cues from Scandinavian folks, who endure even shorter days than we do. For example, the Danes practice hygge (pronounced hoo-guh) as part of daily life. Hygge can’t be translated into English with a single word, but imagine feelings or activities that promote coziness enhanced by candles or firelight….think warm socks and woolen sweaters, friendly gatherings before a roaring fire, warm beverages in your hands, looking dreamily at snowy scenes through frosted window panes, and late afternoon nature walks to catch the last rays of light.

The words of many secular Christmas carols promote feelings of hygge. There is no need to stop at the Yuletide’s end; we should make it our practice to continue hygge through the long winter. Take back the darkness by continuing to light candles or drape strands of white lights, then sit in your most comfy chair under a coverlet and lose oneself in a good book or listen to music, or finish knitting that scarf you started last year. All too soon spring will arrive, and the garden will beckon.

What interpretations of  hygge do you practice in winter? Would you like to share?

Now Revealed

weetamoo_berries2There is much to observe in the winter landscapes surrounding us here in New England. This past Sunday, Chris and I revisited nearby Weetamoo Woods in Tiverton RI. The deciduous trees have mostly let go of their leaves, and what is now revealed might go unnoticed earlier in the season or be at a totally different stage.  For example, above, the pesky green briar offers subtle beauty with its zigzag lines and blue black orbs of fruit against the waning light.weetamoo_woods_bark_moss_lichen_stone500Now, without the distraction of spring’s brilliant greens or autumn’s blazing red and gold tones, natural stone, tree trunks and moss become the main attractions…weetamoo_woods_stone500Look at this end of a wall formation embossed with aged lichen and liverwortsweetamoo_woods_ferninrock500There are colorful surprises…even at some distance, this olive green Rock Fern, happily embedded in a fissure of this sculpted stone, stood out.weetamoe_woods_ferninrock_detail500A closer view of the fern’s habitat.weetamoo_woods_stonewall500A dry laid stone wall still stands proudly and has developed a patina money can’t buy.weetamoo_woods_stream500Life and sounds emanating from this creek announced the remains of an old saw mill nearby.

Note to self: How simple, how peaceful.weetamoo_woods_wall1_500Dry laid stone walls, like this handsome and still structurally sound example in Weetamoo Woods,  acted as boundaries for livestock in earlier days, and now mark “rooms” throughout the property. Here and there, a tree might take root at its base, but a caregiver has seen to it that bramble hasn’t obscured its presence.

We can all be thankful for the simple beauty of our local woodlands, preserved with sensitive editing by the stewards who care for them. Imperfections, such as a wall slightly tumbled, may not be tolerated in some of our more cultivated gardens but are celebrated where the natural landscape rules.

Is there a special woodland walk near you which you find restorative? Perhaps you would like to share a special place with our readers.

From my window…

2016_nov_16outmywindow2webI love an autumn that lingers, that gently let’s go of leaf and blossom, that holds onto color made more vivid against a changing gray sky. A day or two or three of mild temperatures can make us forget that the naked garden of December and January awaits.  Right now I am enjoying this picture from my window, as it about to change, and yet will continue to offer interest in the cold months ahead.

What do you see when you look out your window? Are you pleased with your view? Does it include evergreen plants which add bold mass and keeps some color happening? Is there a nicely pruned tree whose silhouette can show off the tracings of winter snow? And do you notice branches that take on red or gold or purple pigments when temperatures drop, adding subtle hues, (but color nonetheless).

Do your plantings also invite the activity of birds? Will you catch the scarlet flash of a cardinal, who finds refuge in a dense evergreen, or the business of chickadees, who flit from one branch to the next, waiting for safe moments to descend upon the feeder.

From my window, the Hinoki Cypress, Chamaecyparis obtusa compacta, provides a dark green screen from the road, and the winterberry, Ilex verticillata, adds brilliance for at least another month. The Japanese Maple, Acer palmatum ‘Katsura’ will let go any day now, but we’ll suspend a feeder from its branches for the birds. The Forest Grass, Hakonechloa macra, will change from gold to tan. And then in late winter, the scene will flush anew reminding  me that spring is on its way, with color from early bulbs and Hellebores.

Early November Journal

I began keeping this blog as a garden journal, documenting what is in color at particular times of year,  and capturing the surprises along the way. As we begin November, the show continues.ilex_wpeacockmaple72Despite the drought, there is a very good berry set on Ilex verticillata, with the Peacock Maple, Acer japonica aconitifolium echoing red in the background.enkianthus_showyl500Enkianthus ‘Showy Lanterns’ can’t decide which color to turn and is simultaneously taking on shades of yellow, orange, red and maroon.cotoneaster500Cotoneaster franchetti (grown from seed shared through a seed exchange) has a good fruit set this year.euonymus_sp500Prettiest time is now for  Euonymus carnosus, Chinese Spindle Treeaster_ageratoides_ezo500Aster ageratoides ‘Ezo Murasaki’ (or has the name changed to Kalimeris?) has already put up with 28F temperatures and is still offering color.

As summer ends…

stonewall2_500

A+ rating for drought tolerance…Yucca ‘Color Guard’ with Jackman’s Blue Rue, Succulents, Sedums and dwarf conifers. Oh yes, and the amazing yet vicious Solanum quitoense.

Not sure if I am truly sorry to see the summer of 2016 end. There have been days that I’ve thought that an early frost would be a blessing as I dragged hoses about, trying to coax vibrancy into a garden getting more tarnished looking by the day. The forecast for rain never proved to be true, and the number of very hot days set a record. Still, the optimistic gardener within always wins out. Yesterday, I walked about the garden to see what plantings held their own despite the cursed weather. Here’s what I saw.

hydrangea_peewee500

The Oakleaf Hydrangea ‘Peewee’, with flowers aging to russet brown, but with fresh foliage, despite no irrigation.

crambe_maritima91916-1

Crambe maritima (Sea Kale) thrived, and swallowed up the younger plants nearby.

agastache_blackaddeer540

Agastache ‘Black Adder’, with nearby Amsonia hubrictii beginning to turn golden for fall.

lespedeza_gibralter_fall2016-1

Deep rooted Lespedeza ‘Gibralter’ could have cared less about the drought.

eucomisdarkstar540

Little Eucomis ‘Dark Star’, petty in flower and in leaf, with nearby red Heuchera

signpot1_540

Succulents by the road fended for themselves admirably

giant_pumpkin_fall2016-1

Fruit finally formed during  the 3rd week of August on the giant pumpkin. We’ll see…..

cutflowers_fall2016-1

Our overly ambitious cut flower garden….did I know I wouldn’t have extra time for fresh arrangements, ands  planted Celosia and Gomphrena which could also be cut and then dried?

zinnia_queenlime_fall2016-1

You are not seeing the mildewed foliage (intentionally), of the lovely Queen Red Lime Zinnia…

dahlia_detail-1

The blush pink beauty of Dahlia ‘Cafe au Lait’

And so, as I prepare for fall, certainly all was not lost. The garden gave us butterflies and bees, and yes, beauty, in addition to many challenges.  I am game for next year…are you?

Conoclinium coelestinum ‘Cory’

eupcoecory

A new name for the Hardy Ageratum. Formerly Eupatorium coelestinum, the plant taxonomists have bestowed the name Con-oh-clin-i-um on this late summer into fall blooming plant. The species name co-el-est-in-um means heavenly. Clusters of heavenly sky blue flowers atop 18-30″ stems bloom in August and September, attracting butterflies and pollinators. Conoclinium enjoy average, evenly moist soil conditions and spreads by stolons, creating a healthy patch where happy. It makes a lovely cut flower and is hardy in zones 5-8.

Summer Meadow Rues

As the 4th of July rolls around, the early June show of Baptisia, Peonies, Iris and Cranesbill is fading, and its time to focus on high summer performers. I could not be without the dreamy clouds of  the summer blooming Meadow Rues, or botanically speaking Thalictrum, with their sprays of dainty small blossoms on tall stems, creating a seductive haze above the knee high plants in the garden.

thalictrum_splendide2 (1 of 1)

Thalictrum ‘Splendide’

First there is ‘Splendide’, the first of the French breeder Thierry Delabroye’s introductions with its slightly larger soft lavender flowers. ‘Splendide’ is statuesque…it can reach 7′ in a rich soil, and may need staking when the branched stems are heavy with buds.

thalictrum_splendide_white500

Thalictrum ‘Splendide ‘White’

Thalictrum ‘Splendide Whiteis perhaps my favorite. Another selection from Thierry Delabroye, this white selection takes the place of Baby’s Breath in the border with its 3′ to 4 .5′ stems above delicate Columbine like foliage. Sprays of pearly buds  burst into 1/2″ 5 petaled blossoms with greenish white stamens. Blossoms continue for weeks, and make exquisite cut flowers.

thadelhd (1 of 1)

Thalcitrum delavayi ”Hewitt’s Double’

And then there is this older form of the species, T. delavayi,  ‘Hewitt’s Double’, which bears its inflorescence on 3-4′ stems above dainty Maidenhair fern like foliage. It has shown a preference for excellent soil drainage in winter, but enjoys an evenly moist soil during the summer months.

thalictrum_rochebrunianum500

Thalictrum rochebrunanium

Last but not least, is the most familiar form Thalictrum rochebrunanum ‘Lavender Mist’ which can easily grow 4-6′ tall in a rich somewhat moist soil.  Sprays of lavender buds open to show 4-5 petaled blossoms with prominent yellow stamens in July and August.  T. rochebrunianum can self sow where it is content.

Thalictrum are members of the Ranunculus family which includes, Anemones and Buttercups. They enjoy average to rich soil with ample moisture during the growing season and full or half day sun. T. delavayi is hardy in zones 5-8, and the rest are more cold tolerant and are hardy in zones 4-8.  And oh, yes, they are not favored by deer or bunnies.
