Mukdenia should be grown in more gardens and I will speculate why it is not; it has had the misfortune of having more than one Latin name, which gets confusing. For awhile the taxonomists declared it should be called Aceriphyllum rossii, which makes sense (Acer = maple) and the foliage does have exquisite rounded maple like leaves. The cultivar name has a translation that would be easy to remember as well, ‘Crimson Fans’.
I am sweet on its blossoms. In mid spring, Mukdenia produces sturdy 15-18 stems bearing rounded panicles of starry white flowers, just before and as the foliage appears, welcoming the bees into the garden. Mukdenia makes pleasant company for early blooming bulbs and Epimedium. The somewhat glossy, somewhat velvety, dark green foliage forms tight clumps to 12 tall, keeping their good looks all summer, then change vividly to brilliant shades of red when cool temperatures arrive in autumn. Weve found that Mukdenia grows best with afternoon shade in a soil that has good drainage yet is fertile and adequately moist. You will be pleased to know it is hardy in zones 4-8 and is also deer resistant.
Tricyrtis hirta ‘Tojen’
A must have plant for the late summer/fall shade garden is Tricyrtis hirta, commonly known as Japanese Orchid or Toad Lily. There are numerous cultivars; one I am especially fond of is the selection ’Tojen’ , with has unspotted lavender, orchid like flowers held in loose sprays on sturdy stems above large lush foliage.
Toad Lilies enjoys a rich welled drained soil that stays adequately moist in the growing season. ’Tojen’ is more forgiving of drier soils than other cultivars, but I recommended keeping the soil irrigated to keep plants at their best in late summer when they really show off. ‘Tojen‘ grows 24-30” tall by 30” wide and is hardy in zones 5-8. Some great companion plants are Kirengeshoma palmata, Begonia grandis and late blooming Hosta such as ’Red October’.
Aster oblongifolius ‘Raydon’s Favorite’
Just look at this plant in mid October!
A mass of bright lavender blue flowers reward those who have patience and foresight, since Aromatic Aster (its common name) is not much to look at in May and June. Still, it is undemanding all summer long, tolerating dry soil and neglect. In late September, you begin to notice the buds develop color and in a few weeks, it is a sight to behold.
Botancially speaking this Aster has been reclassified as Symphyotrichon, but the gardening public seems to be ignoring this name. ‘Raydon’s Favorite’ typically grows 2-3′ tall, and 3′ wide. It has a little brother, the selection ‘October Skies’ which stays more compact (under 2′) if you are in need of a selection with less height. Aster oblongifolius is super hardy, tolerating even the cold climate of zone 3. It can be dusted with a bit of frost and still look unfazed.
Aster ‘Raydon’s Favorite’ is a perfect compliment to all the oranges and golds of autumn, especially the perennial mum, Dendranthema ‘Sheffield Apricot’ and the colorful Dwarf Witch Alder, Fothergilla ‘Blue Shadow’.
Garden designers may bypass this late blooming hardy impatiens for bolder showier forms, but gardeners with a curious streak will want to try little Impatiens omeiana. Growing only 6-8″ tall for us, I hear it gets to a robust height (12-15″) in milder climates. Apricot yellow flowers with red speckled throats appear in September and October. The notched narrow elliptical dark green leaves have a striking white midline, and since this plant is stoloniferous, it can become a handsome ground cover whether it is in bloom or not. Plants prefer partial to full shade and a soil that is moist during the growing season but require good drainage to winter over. It is native to Mt Omei, China and would make a good companion plant with Tricyrtis, Tiarella and dwarf Rhododendrons.
Just took a break from fall cleanup chores and went to grab my camera to capture a few images. I went to upload into my November 2012 image folder, and noticed the November 2011 folder right next to it, so I had to look. Same day, same garden, different year. Yes, we did some garden editing this spring, but what struck me is the dramatic color difference in the Japanese Maple Acer palmatum ‘Katsura’.

It would be a difficult choice, but if I had to select one deciduous tree for my garden, it would have to be the Korean form of Stewartia pseudocamellia, and this is why: here is a small tree (25-30′) with striking interest in all 4 seasons. In winter, a mature Stewartia pseudocamellia var koreana shows off its handsome narrow pyramidal shape, which broadens a bit with age, and lovely exfoliating bark, exposing shades of tan, pink and gray. In spring, it breaks anew with fresh dark green elliptical leaves, arranged alternately along its branches. In early summer, lovely 3″ white camellia like flowers are displayed. Each blossom only lasts a short time, but there are so many produced over several weeks that you never feel it is not performing. In autumn, Stewartia pseudocamellia is truly mesmerizing, flashing you with foliage in shades of brilliant red, orange, gold and green.
Stewartia pseudocamellia is native to Japan and Korea, and the Korean form is generally considered a bit hardier. The Korean form tends to have a more narrow pyramidal shape than the species found in Japan. In its native habitat, it is found growing with Clethra barbinervis and Enkianthus campanulatus, both exceptional large shrubs or small trees, with multi season interest. Stewartia pseudacamellia var. koreana grows best in sun or partial shade in a humus rich but well drained soil, out of strong wind. It is hardy to minus 20F and grows well in zones 5-8.
Here is a little plant that is versatile, super hardy and foolproof (as long as you grow it in sun and well drained soil). It hasn’t been in the US very long, but already has acquired the common names of “Chinese Stonecrop”, as it hails from Asia, and “Coral Reef” , (still not sure what the Coral Reef reference is). Sedum tetractinum grows only 1-2″ tall, and spreads modestly, rooting into the soil as it creeps along. It is especially dramatic spilling over edges: retaining walls, pottery, troughs, you name it.
Sedum tetractinum is also lovely enough to use in mixed succulent planters. Its rounded olive green leaves turn a lovely copper bronze shade in the autumn, and this color change contrasts well with other shades of succulent foliage. In the planter you see here it is paired with tender Sedum adophii and Euphorbia tirucalli, but it could easily accent hardy Sedum ‘Angelina‘ and Sempervivum. Pale yellow flowers appear in summer, but the blossoms are not the highlight. “Chinese Stonecrop” takes temperatures as cold as minus 30F (zones 4-9).
Viburnum dilatatum ‘Michael Dodge’
Meet ‘Michael Dodge‘, a golden berried hybrid of Linden Viburnum. He is a cheerful fellow, who shows off in late spring with a bevy of white lacey flowers and then later develops clusters of showy yellow fruit, which is a sight in our garden right now. The birds are leaving the fruit alone, but that is fine with me because the fruit bearing stems are perfect additions to autumn floral arrangements.
I received a nice note from the plant’s breeder, Mr. Michael Dodge himself. He informed me that he made a deliberate cross between V. dilatatum and V. d. Xanthocarpum in hopes of getting a larger fruited yellow form in his days working at Wintherthur in Delaware. Mr. Dodge left Winterthur not long after, but was notified that there were some very nice clones from the seedlings he planted. Harold Bruce, the garden curator at that time, named the best yellow fruited clone after him.
Viburnun dilatatum is of Asian ancestry and although it looks perfectly at home in a naturalistic border, it is not as favored by birds and wildlife (plant V. dentatum and other native viburnum species). What it does do is provide dramatic color in the autumn landscape. Something you should note is that in order for a good berry set you need another cultivar of V. dilatatum nearby. This may sound confusing, so I should clarify. You should plant a different clone for good cross pollination, and Mr Dodge specifically recommends Viburnum dilatatum ‘Cardinal Candy‘, who will put on a show of its own with bright red fruit.
Viburnum dilatatum ‘Michael Dodge‘ will grow 8-10′ tall and wide. He is not fussy about soil, but will certainly appreciate a fertile loam and grows best in full sun or partial shade. ‘Michael Dodge is hardy through zone 5.
The longer we garden the more we appreciate both subtlety and contrast… especially when a plant makes you do a double take because of some extraordinary features. Boehmeria platanifolia is one of these plants: unique foliage, size, with late summer pale green flowers. This species of Boehmeria has large sycamore shaped green leaves (up to 5″) with serrated edges and covered with tiny hairs giving the plant a soft glow. The leaves attach to the sturdy stems with contrasting red petioles. Green tassel flowers emerge from the branch tips in August and continue to droop into the fall.
Boehemeria platanifolia performs best in partial shade, in a soil that is evenly moist. Established plants can grow to 5′ tall and 4′ wide. It is a Japanese member of the Nettle family, Urticaceae, and this particular species is quite hardy…reports say to zone 4, but we’ll play it safe in saying it will grow well in zones 5-8.
Combines well with Tricyrtis (toadliles), Begonia grandis (Hardy Begonia) and Leucoseptrum (Japanese Wood Mint) in the fall shade garden.
Those of us in northern climates are suspicious when we’re told showy evergreen Euphorbia are hardy for us (zone 6), with good reason. Arctic winds and lack of snow cover often dessicate the foliage and those the early blooms. Well we’ve had mixed results with the fabulous Euphorbia ‘Ascot Rainbow’, and what we’ve learned is it’s all about siting. That being said, we’d grow this plant regardless of winter hardiness because it looks good for the entire growing season, from early spring into December.
Euphorbia ‘Ascot Rainbow’ is a selection of E. x martinii. It boasts beautiful gold and green variegated foliage tinged with coral red, especially on the new growth and when temps are cooler. Multiple red stemmed branches form 18-24″ mounds. Euphorbia ‘Ascot Rainbow’ blooms on new and old growth, with adorable variegated bracts exposing tiny red flowers. I’ll say this again, this plant looks fabulous the entire growing season here in New England, and because of this it is equally as wonderful in containers as it is in open ground.
Now in regards to siting: we used Ascot Rainbow in container plantings at an urban restaurant, where they looked so fabulous at the end of the winter that we left them in for the spring display. Really! In this protected spot, surrounded by buildings radiating heat, the Euphorbs were quite happy. In open ground we’ve had mixed results. In a raised bed with good drainage the plants came through, although we had to cut back the sad looking evergreen foliage after the winter. Snow covered much of the ground during the winter of 2010 and 2012 and our plantings came through unscathed. The recommendation: good drainage, protection from wind, in sun or partial shade.
