You won’t pay much attention to Blood Twig Dogwood in spring and summer. The ordinary green foliage is attractive enough, but it does not sing “Here I am!”. It’s not until autumn, when Cornus sanguinea ‘Arctic Sun’ starts to make music in clear apricot tones with the changing fall foliage. Colder temperatures transform its green branches into stalks of vibrant yellow, orange and red which glow in an otherwise increasingly dull landscape.
‘Arctic Sun’ (a.k.a. Cornus sanguinea ‘Cato’) is a compact clone of Blood Twig Dogwood, reaching only 4-5′ tall as opposed to 8-10′, and this size is useful in smaller gardens. It thrives in average to moist soil in full sun or part shade, is deer resistant, and is hardy in zones 4-7, which means it will take temperatures to minus 30F, but probably won?t be happy in mild winter climates. We recommend planting ‘Arctic Sun’ in a location so that the dazzling winter stems can be viewed from an inside perch, perhaps where you sit with your morning coffee, or where you might pass by as you enter and leave your home. You’ll enjoy the show all winter, and may even be inspired to cut a few branches for decoration.
One thing you should note is that the best color on twig dogwoods is displayed on young wood. Every two or three years you should “stool” yours plants in early-mid spring. Stooling is a simple pruning technique where you cut back the entire shrub to about 6′ above ground. The new growth will provide a more colorful display when late fall and winter arrives.
We seldom use the phrase “to die for” (such a price!) but this is an apt descriptive phrase for the gorgeous Paeonia ‘Bartzella’. It is one of the Intersectional or Itoh hybrids, named for the hybridizer Toichi Itoh who was the first to create crosses of tree peonies with herbaceous ones. The resulting plants are herbaceous, but with foliage and flower forms characteristic of tree peonies. They command a pretty price because supplies are limited.
‘Bartzella’ boasts large (to 9″) semi double to double warm yellow blossoms with just a hint of red at the base of some of the petals in late spring. The blossoms emit a spicy scent and are borne on sturdy stems that do their best to support such humungous bounty. The foliage remarkably remains fresh and clean all summer. Eventual height and spread should be about 3′. Plants appreciate a well drained neutral soil in full sun or partial shade (some shade is preferable in warmer climates). Care should be taken when planting the roots that the eyes should face upwards and not more than an inch below the soil surface (including mulch). Plants may take a year to bloom, but we were ecstatic when we were blessed with at least a half dozen blossoms the first year after planting. Hardiness range is zones 4-7.
Peonies are available barefoot in mid autumn, and grown in containers at better nurseries for year round sale.
Fall blooming Anemones are the prima donnas of the autumn garden. This selection, commonly called Grape Leaved Anemone, begins her performance in late August. Simple and beautiful saucer shaped blossoms, consisting of 5 dusky pink petals, surround orange yellow centers on 2-3′ sturdy stems. The dance continues through September.
Some folks complain that they have trouble establishing Anemones. This is not because they are not hardy, for they can easily tough out winters through zone 5, if not 4. However, they do not want to be wet in winter, so be sure you situate them in a well drained soil. They do appreciate even moisture during the growing season, however, so irrigate as necessary, and spread mulch over their roots which will aid in keeping the soil moist. In hot summer areas, grow where some afternoon shade is available. Some people complain it spreads too much!
Another tip: Anemones prefer a neutral or slightly alkaline soil. If you’re unsure of your soil’s alkalinity, test the pH, and add ground limestone in the fall if your soil proves to be acidic. Where they are happy Anemones spread, and can be divided in spring every 3-5 years. Anemones often break dormancy late, so be sure to mark where they have been planted so you do not mistakenly unearth the sleeping roots, thinking you have a big empty hole to fill.
Hayes Starburst Hydrangea is a floral arranger’s dream. This chance discovery, by Hayes Jackson of Anniston, Alabama, differs from the species by its showy display of clustered greenish white, multi sepaled star shaped flowers. It is a form of Hydrangea arborescens, also known as Smooth Hydrangea or Hills of Snow, and although native to the southeastern U.S., is cold hardy into zone 4.
Hydrangea arborescens ‘Hayes Starburst’ blooms on new wood, so there is little danger of winter damage to flower buds. We recommend cutting back the woody stems to 12″ in early spring to keep the plants tidy. Hydrangea arborescens prefers to grow in full to half day sun and in a well drained soil that still gets adequate moisture. If there is a common complaint about this species it would be that the flower clusters are so heavy that they weigh down the supporting stems. Some consider this an addition to the plant’s charm, and if it is sited on a slope or above a retaining wall, you could take advantage of its cascading habit. If an upright habit is preferred, situate a large tomato cage over the cut back stalks in spring, which will lend support. The height and spread of this shrub can remain a manageable 3′ x 3′, if pruned annually.
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.
