Phlox paniculata ‘Jeana’

July 12, 2020 Katherine Tracey 5 Comments

I’ll give you 3 reasons why you should have ‘Jeana’, a Summer Panicle Phlox, in your garden.

1. Long-blooming tresses of many small lilac sized florets, on 4-5′ stems, adorn this plant from mid July-September.

2. The foliage is highly resistant to mildew.

3. Butterflies favored ‘Jeana’ over all other Phlox paniculata selections in the trial gardens at the Mt. Cuba Center.

Phlox paniculata ‘Jeana’ is hardy in zones 4-8 and enjoys full sun. For a pleasing midsummer vignette, combine with white coneflowers or the yellow daisies of tall Rudbeckia nitida ‘Autumn Sun’, as well as the blue spires of mid-sized Agastache ‘Blue Fortune’ and for the front of the border airy and pollinator friendly Calamintha nepeta ssp nepeta.

A Versatile Fall Aster

September 18, 2019 Katherine Tracey Leave a comment

Heath Aster planted itself in the dappled shade of our oak tree.

I take no credit for planting the occasional surprise of native Symphyotrichum ericoides (heath aster) in our gardens…they just appear and often in just the right spot. Unobtrusive all summer, but a delightful accent when flowers form in mid-September, Heath Aster presents 1-2′ stems bearing hundreds of tiny white daisies with yellow centers, creating a frothy foam in both sunny and even somewhat shady areas.

There are selected forms out there….‘Snow Flurry’ stays quite low at 6-8″ with 2′ branches that hug the earth, making it a useful native ground cover for the edge of a border or in the rock garden. A new selection ‘Bridal Veil’, introduced by the Chicago Botanic Garden, is believed to be a naturally occurring cross of ericoides and “?”. It produces strong 2′ arching stems with copious amounts of blossoms and forms vigorous clumps.

All forms of Heath Aster prefer well-drained soil and are quite drought tolerant once established. As I mentioned we’ve had plants pop up in even shady situations, but I think you get more flower power with full sun. Deer resistant and pollinator-friendly and hardy in zones 5-8…yay!

Two Plants to add a little Fall Excitement

September 9, 2019 Katherine Tracey 4 Comments

All summer long Plectranthus ciliatus masquerades as a khaki-colored Coleus. Come early autumn, all of a sudden floral spikes extend and open up into chunky spires of lavender-blue flowers. It does need to be protected from frost. but we’ve solved this problem by covering plants with a blanket on those pre-Indian Summer nights when the temperatures dip. Easy peasy to grow indoors for the winter, as it can get by with indoor lighting.

Folks always admire this succulent Senecio early in the season for its display of blue-gray tufts of foliage. However, when late summer rolls around flowering stalks emerge and open up to showy 1″ red-orange buttons. Use Senecio ‘Blazing Glory in a pot by itself or mix with other succulent goodies. Yes, it is a plant that needs protection from frosts., but it is super easy indoors on a sunny window sill.

Vernonia x ‘Southern Cross’

July 26, 2018 Katherine Tracey 3 Comments

Do you have room in your garden for a late summer/early fall blooming perennial that attracts butterflies galore? This Ironweed has dreamy clouds of composite purple flower clusters on sturdy stems 3-4’ tall beginning in August and its handsome narrow foliage looks fresh all season long. Discovered by Brent Horvath of Intrinsic Perennials, ‘Southern Cross’ obviously has the species lettermannii in its heritage. This selection combines beautifully with ornamental grasses such as Sorghastrum, Schizachyrium and Eragrostis.

‘Southern Cross’ appears to like extra moisture the first season but becomes more drought tolerant once it is established. Plants are hardy in zones 4-8 and should be deer resistant.

Glows in the Shade: Tricyrtis ‘Autumn Glow’

July 9, 2018 Katherine Tracey Leave a comment

We are always looking for summer blooming perennials for shade, and here’s one you should consider. Many of us notice plants when their blossoms present themselves , and indeed Tricyrtis ‘Autumn Glow’ does captivate with its purple-blue orchid like flowers. I say that this form of Toad Lily deserves attention for its large and bold golden edged foliage. Ovate leaves grow to 6″ long and 3” wide and plants enjoy a rich, somewhat moist but well drained soil. Plants spread by stolons and clump up quite quickly, growing to 2’ tall and up to 3’ wide in dappled shade. ‘Autumn Glow’ is reliably winter hardy in zones 5-8.

Tricyrtis ‘Autumn Glow’ still showing off in early October

The flowers, born in sprays from late July into early October, are lovely as cut flowers and do attract butterflies. Pair Tricyrtis ‘Autumn Glow’ with ferns, such as Athyrium otophorum, or golden leaved Hosta for a nice shady vignette.

Spring Color, Trees and Shrubs

Stachyurus chinensis ‘Celina’

March 26, 2018 Katherine Tracey 3 Comments

Shrubs and trees which flower on old wood, just before the leaves unfurl, have a special charm. Think Witchhazel, Native Dogwood, Redbud. One that we especially love and isn’t so well known is Stachyurus chinensis ‘Celina’. This shrub bears pendant racemes of creamy white/yellow flowers in early spring (April for us). We have ‘Celina’ planted in a sheltered spot from winter winds, which can desiccate the flower buds. This area is shaded by a Japanese Maple and gets 4-6 hours of sun. Our 7 year old plant is about 4′ tall with arching branches from the base, reaching to about 6′ in width. We expect it will grow to 8′ x 10′ eventually. Fall color varies year to year, but we’ve seen it take on yellow and orange tones. hardy in zones 6-9.

Containers 2017…the before shots

July 1, 2017 Katherine Tracey 4 Comments

Here it is the end of June, and the most of our containers are planted. These are low maintenance ensembles: the goal is to have them still looking fine at September’s end, with minimal care during the summer. As you might expect, foliage plants, especially succulents, play a big role because of their reliable good looks.

You’ve seen this pot before, but each year I vary the ingredients. This year the 36″ Zen Bowl has an interesting collection of Graptoveria, Aeonium, Euphorbia, Sedum and Senecio.

The green drum pot boasts a specimen Aeonium hybrid with x Sedeveria ‘Harry Butterfield’ and Senecio rowleyensis (String of Pearls).

Again, the tall cylinder pot in front of the garage has a repeat performance with a few of last year’s plants…Kalanchoe behartii, Aeonium ‘Cyclops’ , Echeveria ‘Swirl’, x Graptosedum ‘California Sunset‘, Senecio ‘Mini Blue’, a Rhipsalis and silver leaved Dichondra.

For a sunny spot….some tender perennials with flower power. Digiplexis ‘Illumination Flame’ is not hardy for us in the ground, but it is a long summer bloomer in pots. Ruellia ‘Purple Showers’ adds some dark contrast with foliage plants Euphorbia ‘Ascot Rainbow’, Heuchera ‘Caramel’, and Hedera ‘Amber Waves’ adding long season interest. The smaller pot to the right has Heuchera ‘Cherry Cola’, Phormium ‘Sundowner‘, and Euphorbia ‘Diamond Frost’, with a matching Hedera.

This 20″ wide Grecian urn is in quite a bit of shade, so I’ve used the variegated dwarf Papyrus Cyperus ‘Starburst’, with dark purple leaved Oxalis, Begonia ‘Art Hodes’, Sansevieria ‘Moonshine‘ and trailing over the sides, Callisia congesta variegata

New pot, new spot. Green, silver and black color scheme. Dappled shade all day. Used Maidenhair Fern Adiantum pedatum, with Sansevieria ‘Moonshine’, Black Mondo Grass Ophiopogon planiscapes Nigrescens, Begonia grandis, which will get big and add height as the summer goes on, and I’m trying out Dichondra in the shade. We shall see…

The 14″ green planter has both a green and a variegated dwarf papyrus, with Ornamental Oregano Origanum rotundifolium ‘Kent Beauty’ and Callisia congesta variegata. The dusky plum leaved plant on the right is Tradescantia ‘Pale Puma’ .

The False Agave Beschoneria ‘Flamingo Glow’ is accented with ivies and oxalis…Hedera ‘Amber Waves’ and congestifolia, plus Oxalis ‘Iron Cross’ in the iron urns which get only 3 hours of afternoon sun.

A simple planting of hardy Sempervivum ‘Pacific Blue Ice’ with teensy creeping Sedum sexangulare are just the right plants for the small planting cavity of this face pot.
I can just tell this brown terra cotta bowl is going to be outrageous when fall arrives…the succulents used include Sticks on Fire Euphorbia tirucalli rosea, Senecio ‘Blazing Glory’, Crassula ‘Hummel’s Sunset’ Sedum ‘Firestorm’, and String of Pearls, Senecio rowleyensis.

Uncommon Pollinator Plants

June 19, 2017 Katherine Tracey Leave a comment

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

Asclepias 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.

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.

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.

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.

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.

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

Formerly White Upland Aster or White Goldenrod depending who you asked, but 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.

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

June 5, 2017 Katherine Tracey 1 Comment

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.

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 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’

May 9, 2017 Katherine Tracey 2 Comments

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, Magnolia ‘Sunsation’ 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.
