The best selection of Woodland Phlox, in our opinion, is this lovely cultivar introduced by Bill Cullina, of Coastal Maine Botanical Garden. Abundant deep sky blue flowers on 12″ stems perfume the May garden, and when planted en masse create ethereal drifts. It makes an excellent companion for woodland poppies and late blooming narcissus
‘Blue Moon’ grows best in light shade in a rich humusy soil that is moist yet well drained, forming clumps 2-3′ across. After the blossoms fade, cut back the spent flowering stems for a neater appearance. It is hardy in zone 4-8.
Here on High Hill Road, much of the winter is spent searching for sources of the most promising new plants available in the horticultural market. We’re always optimistic, but we hold all newcomers to the standards set by great plants introduced in the past. Clematis macropetala ‘Lagoon’ introduced in 1958 by George Jackman and Son, has been on the market 52 years. Wow! This is comparable to the career of BB King and just as blue, but “the thrill is not gone”.
We planted Clematis m. ‘Lagoon’ at the base of a mop-headed silver leaved Capulin Cherry, Prunus salicifolia. That “bad-hair-day” cherry’s branches bowed down and insisted on giving ‘Lagoon’ a ride. As early as April, this vigorous clematis beguiles nursery visitors with blue blossoms as it adorns the branches of its silvery companion. “What is that blue flowering tree out near the parking area?” we are asked. You won’t need a tree to enjoy this 6 to 10′ vine, as it would do equally well climbing a trellis or arbor.
Clematis macropetala ‘Lagoon?’ needs little pruning. If it does get too rambunctious where it is planted, it can be pruned back in late June or July, after it has finished flowering, since it blooms early on old wood. Clematis like a slightly alkaline soil, so scratching in a handful of dolomitic limestone will keep it happy if your soils tend to be acidic. It is very hardy, growing well in USDA hardiness zones 3-8.
Gardeners in northern climates have been disappointed by Hydrangea macrophylla in the past….lots of healthy foliage, but few or no blossoms. This recent introduction of Mophead Hydrangea truly blooms on both old and new wood, and is being marketed as ‘Forever and Ever Red Sensation’ ( Tra-la-la…those clever marketers read a lot of fairy tales).
What you really need to know is that this vigorous selection produces lots of blooms on new growth, making it a great candidate for colder zone 5 and 6 gardens. In hot climates the large trusses of blossoms will be in softer shades of rosy pink when grown in neutral to slightly alkaline soil. Colder temperatures will cause the flower color to deeper red shades. If your garden soil happens to be more acidic, ‘Red Sensation’ will change color and thus need a new name, as it will take on bluer tones. The flowers age to smoky violet. Stems and fall foliage color have a dark burgundy cast.
‘Red Sensation’ grow 2-3′ tall and 3-4’wide, and require full sun or partial shade. Hydrangea macrophylla appreciate a moist, rich and fertile soil. May we suggest combining ‘Red Sensation’ with the always attractive Periscaria ‘Golden Arrow’?
What has spring time blue flowers, grows 4-6″ tall, spreads by creeping runners, thrives in partial shade or shade in moist or drier soil? Meehania cordata, commonly known as Meehan’s Mint! This versatile and underused Northeast native is a good substitute groundcover for Lamium and Ajuga. It blooms in May and June with violet blue lipped tubular blossoms and would make a lovely underplanting for golden leaved Hosta and Hakonechloa (Japanese Forest Grass).
Although it is especially vigorous in moist soil, and would be a good choice for carpeting along a pond or stream, it will also grow well but more slowly in drier spots. It is hardy in zones 5-8 and would be a welcomed addition to a wildflower garden.
We have fallen in love with the New England forest. It happened several decades ago, but it seems like only yesterday that the spell of fall was cast upon us. We know it’s the maples celebrating, in a festival of color, their happy home. A selection of Japanese Maple, Acer palmatum ‘Orange Dream’ begins this celebration in spring, with leaves emerging orange, unfurling to lemon-yellow with orange margins and finally settling in with yellow-green tones through the summer. Fall harkens ‘Orange Dream’ with a glorious display of yellow-gold. As winter peels off her leaves, the architectural intricacies of this small tree are revealed. Each season bring forth a new song from the branches of Acer palmatum ‘Orange Dream’.
‘Orange Dream’ appreciates an eastern exposure, where her feet will stay cool through the summer. She grows only a few inches a year, but will eventually find her way to 10′ x 10′. Site in a small garden or as an understory and you will fall in love too.
So many of the earliest spring bloomers are diminutive in size, and invite you to kneel or even lie on your belly for the best viewing. Blooming with the early Crocus, the lovely and demure Iris ‘Katharine Hodgkin’ first appears as a pale yellow-green shoot, and then begins to unfurl to display falls and standards in the most ethereal shade of pale aqua etched with baby blue. Pastel orange-yellow markings accent the falls, and as her flower ages, ‘Katharine Hodgkin’ fades to delicious shades of blue-gray.
Although it is often sold as I. reticulata, Iris ‘Katharine Hodgkin’ is in fact a cross between 2 species, I. histroides, native to Turkey and I. winogradowii native to the Caucasus. She is a hardy soul, surviving in zones 4-9, and grows 4-8″ tall, preferring a well drained sunny situation that gets adequate moisture in late winter and dryness in summer. Planting and dividing is best done in the fall, but mark then spot, because she goes dormant in early summer.
There are rare colors in the plant world, and black is certainly one of them. This new selection of Lenten Rose, from the hybridizing efforts of Ernie and Marietta O’Byrne, is one of the darkest shades we’ve seen. New growth emerges in early March here in New England, gradually sending forth flowering shoots as kinder weather warms the earth. The nodding single rose shaped flowers begin to fade in early May, after which the swollen ovules will burst, dispersing the ripened seed. Seed most likely will not germinate until the following spring, and the seedlings will likely differ in color from the parent plant, as this is a hybrid. New foliage will continue to develop as the flowers fade and the handsome leathery leaves persist through the winter.
Hellebores appreciate being grown in a partially shaded, well drained, fertile, slightly alkaline soil (pH of 7-6). Individual plants usually grow 18-20″ tall, forming sizable clumps over the years, and will withstand temperatures to -20 degrees F.
Perhaps you first noticed this primrose depicted in one of those classic 17th c. still life paintings, one of many plants in an opulent ensemble that one would never find blooming all at once in nature. Primula auricula in its purest form is native to the alpine regions of central Europe, growing in sharply drained soil on craggy slopes, enhanced by moist mountain air. The species often display cheerful yellow flowers that extend on 4-6″ stems and are hardy through zone 4.
British gardeners have made collecting and growing Primula auricula a springtime passion and, over the years, have hybridized and selected forms with larger flowers, sturdier stems, and unusual colors ranging from mustard, tan, yellow and green through red, purple and almost black, sometimes accented with white picotee edges. Often a powdering coating called “meal” dusts the flowers, leaves and stems. These “show hybrids” are best grown in pots rather than open ground, where their need for well drained soil that still remains adequately hydrated can more easily be met.
There is something especially striking about flowers which adorn bare branches before any signs of leaf growth appear. Hamamelis x ‘Feuerzauber’, a German hybrid selection of Withchazel (translation Fire Dragon), is hardy in zones 5-8 and boasts showy orange to red fragrant flowers in late February and March, which are as lovely cut for indoor arrangements as they are gracing the late winter landscape.
We recommend situating ‘Feuerzauber’ where you can enjoy its display from an indoor window. In fact, why not plant early blooming Crocus or yellow Narcissus ‘February Gold’ near its base for one of the first colorful ensembles of spring. ‘Feuerzauber’ will form a large shrub (15-18) with a pleasing upward spreading habit. It may not sing loudly in summer but it will celebrate Autumn with an amazing symphony of orange, yellow and red foliage.
