Iris - Native to Alaska Iris setosa Description This perennial wild Iris is also called Beachhead, Knik Germplasm, and Blue Flag. These Irises bloom in June and July and the flower doesn’t have a scent. Established wild Irises produce 3 to 4 blooms on each stalk annually. Prefers moist soils and will grow well in ditches; and along streambanks, and ponds. Form Grows up to 12-24” tall Vibrant violet flowers June-July Zone 3-9 Plant Characteristics and maintenance Use in revegetation and erosion control-root stalks hold soil firmly Vigorous seedlings that increase naturally with little maintenance Takes 2-3 years from seed to blooming adult plant Attracts pollinators Antonovka Apple – Non-Native Species Malus pumila Antonovka Description This disease resistant heirloom variety produces a high acidic (tart) yellow apple, but is complimented with its intense sweetness. Good for eating fresh when fully ripe (yellow, not green). Also good for baking, cider, sauces and even apple wine. This tree has the ability to sustain long harsh winters typical of Northern Europe and Russia, its place of origin. Superior fruit preservation qualities (3 months under refrigeration), allowing fruit to “sweeten up” during storage. Form Grows up to 25-35’ tall Produces white flowers in April A fairly large, bright greenish-yellow apple, often with russeting. Russeting is a patch of the apple’s skin that is a different color (golden brown, burnt amber, grey) from the rest of the apple, and also has a sandpapery texture. Extremely cold hardy for Fairbanks, AK Seeds can be sown to produce non-hybrid trees (plants that look and function the same as the parent plant). Plant Characteristics and Maintenance Plant in well-drained soil, can grow in heavy clay soil, requires moist soil Needs 12-15 gallons of water per week May-Sept. Can grow in semi-shade Plant each tree 12-16’ apart Requires protection from moose Winter mulch protection during early growing years Requires different variety with same bloom period for adequate pollination Can prune in summer to maintain 8ft Zone 3-9 Kiska Raspberry – Non-Native Species Rubus idaeus Description This Interior Alaska cultivar is very cold hardy, however it has lower quality fruit as it is a hybrid between wild raspberry and Rubus Cuthbert. It is a summer bearing red raspberry variety that produces sweet fruit. Plants begin to bear fruit during their second year. Summer bearing raspberries tend to have good eating and freezing characteristics. Plants are spiny and produce many suckers. Very cold hardy cultivar, a good selection for Interior Alaska. Keep this cultivar away from wild raspberries as insects bring diseases from the wild raspberries to the Kiska. Form Growth Habit – perennial trailing plant Height – up to 6 feet Width – up to 3 feet Spacing – about 2 ½ feet apart in rows. Rows 8 feet apart Plant Characteristics and Maintenance Flowers early summer Fruiting in late summer and requires moist soil conditions during this time (1” per week) Soil requirements: slightly acidic (6.0) fertile and well drained soils Lighting: tolerates full sun but prefers part sun part shade during fruiting Maintenance: Requires trellising that increases yield of berries. Fertilize early with a balanced fertilizer and again with high Nitrogen fertilizer early bloom at 1 pound per 100 square feet. Care and Pruning: Floricanes (fruit bearing canes) die after they are fruited and should be removed once they turn brown in the fall. Also remove all but about 6 live canes per linear foot, keeping the larger ones. Must thin if to continue producing. Zone 2 Roseroot (Rhodiola) – Non-Native Species Rhodiola rosea Description Roseroot is a tough but beautiful artic succulent that requires little care. It is a perennial herb with a rose-like fragrance that arises from its yellow flowers and has historically been used in perfumes. Roseroot can be used as an ornamental which tolerates rocky soil. Female flowers can turn orange and red, adding to its visual appeal. Because of our long summers, one plant can produce multiple cycles of flowers. Its young succulent leaves and shoots can be eaten raw or cooked like spinach. After 5 years, the roots can be harvested for their medicinal value! The roots are packed with adaptogens which help humans counteract stress and depression, and enhance physical and mental performance. Roots are harvested, washed, chipped and then dried. Roots can be divided and replanted as long as root piece contains part of the plant crown, and a rhizome with root hairs. Form Growth Habit – creeping ground cover to erect Height – up to 18” tall Spacing – 1’ x 1’, perhaps even 1.5’ x 1.5’ Plant Characteristics and Maintenance Planting tip: wait to plant into ground until 1-2” tall. Consider potting for the first year, than transplanting into the ground the second year for added root growth and plant vigor. Flowers May-August Soil requirements: moist fertile well drained soils of various textures and pH, can tolerate drought, however consider watering during extended drought periods. Maintenance: relatively low. Lighting: Cannot grow in the shade Hardy to Zone 2 Red Osier Dogwood – Native to Alaska Conrus sericea Description A deciduous medium-sized ornamental shrub forming a thicket of coral red stems that provide beautiful winter color. Its rapid growing (>24” per year) ability allows for a quick filler of space. A fibrous root system allows Dogwood to be an effective erosion control on banks and slopes. It produces small white clusters of flowers in the spring followed by pea-sized drupes or berries in late summer. Form Growth Habit – Thicket-forming Height – up to 9 feet Width – up to 10 feet at maturity Spacing – 3 to 4 feet to make a hedge Plant Characteristics and Maintenance Flowers during Spring, produces coral red stems Soil requirements: Myriad of conditions, including wet soil. However, does not tolerate excessively dry soil. Lighting: partial to full sun, minimum of 4 hours of unfiltered sunlight daily Maintenance: needs regular watering during first year of growth. Easy to transplant. Needs to be pruned once a year. Can be cut back to the ground regularly for the red color of the younger stems to be more prevalent. Zone 2-7 BEARBERRY also known as Kinnikinnick –Native to Alaska Arctosaphylos uva-ursi Description Pure stands of bearberry can be extremely dense, with heights rarely taller than 6 inches. Erect branching twigs emerge from long flexible prostrate stems, which are produced by single roots. The finely textured velvety branches are initially white to pale green, becoming smooth and red-brown with maturity. The leathery dark green leaves are an inch long and have rounded tips tapering back to the base. In fall, the leaves begin changing from a dark green to a reddish-green to purple. Terminal clusters of small urn-shaped flowers bloom from May to June. The perfect flowers are white to pink, and bear round, fleshy or mealy, bright red to pink fruits. This smooth, glossy skinned fruit will range from 1/4 to 1/2 inch in diameter. The fruit will persist on the plant into early winter. Form Growth Habit – dense mat Height – 2-8” tall Width – 3-9’ Physical Characteristics and Maintenance Lighting: Prefers full sun but has been found growing in the forest under a 50 – 75% canopy. Maintenance: This shrub species requires very little maintenance once it has been established. Fertilization: Annual spring applications of 10-10-10 will increase the growth rate of bearberry. Weed control: Weed growth must be controlled to sustain healthy stands of bearberry Zone 2-6 Landscape Attributes and Uses Bearberry serves a dual role on sandy soils, as both a beautification plant as well as a critical area stabilizer. Bearberry is a very popular ground cover. The fruit it produces is eaten by a few species of songbirds and game animals. Silverberry – Native to Alaska Elaeagnus commutata Description A rounded, twiggy shrub, 1- 7 ft. tall, with narrow, silvery leaves on grayish-red branches. Small clusters of inconspicuous, cone-shaped flowers are spicily perfumed with a heavy, sweet scent. The fruit is a dry, mealy, whitish berry. It is fast-growing, long-lived, and resistant to disease, insect problems and drought. Silverberry transplants well, due to a shallow root system. A very hardy species for cold climates. Form Growth Habit - Narrow, upright Crown Height – up to 7 feet Crown Width – up to 6 feet Suckers profusely Physical Characteristics and Maintenance Moisture: Prefers subsoil moisture as opposed to water-logged or ponded sites. Drought tolerant. Light: Full sun or light shade. Hardy to Zone 2 Uses and Landscape Attributes Good as massed for color accent on grounds/landscape Dense thickets provide cover for many wildlife species. The thorny shrubs also provide good nesting sites for birds. Fruit used as food for song and game birds. Hoofed browsers may feed on leaves and twigs. This species is used as food plants by Lepidoptera (moths and butterflies). Nitrogen fixation: Many Elaeagnus species harbor nitrogen fixing organisms in their roots, and are therefore able to grow well in low-nitrogen soil. The extra availability of fixed nitrogen in the plant makes its leaves more nutritious. White Spruce – Native to Alaska Picea glauca Description A conifer with four sided evergreen needles that grows up to one hundred feet tall. The branches grow in a conical shape so the snow will fall off. The bark is brown, thin and scaly. The cones are short and fat. They generally live to between 100 and 200 years old. Form Slow growth A straight, tall tree easily recognized by its needles. Cones always hang down. Beautiful year-round color. Grows to 100' tall Grow to 15' wide (spread) Physical Characteristics and Maintenance It is a northern tree which can tolerate cold climates. It has a shallow root system that spreads outwards rather that going down as an adaptation to cold climates. Soil Requirements: Tolerates most soil conditions. Zone 2 Uses and landscape Attributes Good shelter/habitat for wildlife. Native Alaskan plant. Low maintenance Alaska Birch – Native to Alaska Betula neoalaskana Description A native deciduous tree of Alaska. It is a slender tree with smooth and creamy white bark which tears off in papery layers. It has simple leaves that are triangular shaped with serrated edges. It has a shallow root system. It is a northern tree that has adapted to cold climates. It is found in areas with short cool summers and long cold winters.

Low maintenance Zone 3 Uses and Landscape Attributes This is a relatively low maintenance tree, and should only be pruned in summer after the leaves have fully developed, as it may 'bleed' sap if pruned in late winter or early spring. Saskatoon Serviceberry –Native to Alaska Amelanchier alnifolia Description This serviceberry cultivar is a compact, deciduous, early-flowering small shrub. 5-petaled, showy, slightly fragrant, white flowers appear before the leaves emerge in early spring. Flowers give way to abundant, small, roundish, green berries which mature to a dark purple in early summer (typically July). Edible berries resemble blueberries in size and color and are often used in jams, jellies and pies. Finely toothed, rounded, dark green leaves change to variable shades of yellow and red in autumn. Form Height: 4 to 10 feet Spread: 4 to 6 feet Bloom Description: White Flowers: Showy Flowers Leaves: Good Fall Color Fruit: Showy, Edible Fruit Plant Characteristics and Maintenance Lighting: Full sun to part shade Water: Medium Easily grown in average, well-drained soil Soil Requirements: Tolerant of a somewhat wide range of soils. Root suckers are common, and if not removed, will result in a shrubby growth habit for the plant. Maintenance: Low Zone 2 Uses and Landscape Attributes Wildlife: Attracts Birds Dwarf Russian Almond – Non-Native Species Prunus tenella Description: Bountiful, early spring flowers are rose-red and quite striking. Dark green leaves turn yellow-orange in fall. The shrub is self-pollinating and can produce velvety, oval fruit about 3/4" long. The nutty, grayyellow-tan fruit make this a good small shrub for wildlife browsing. This shrub is very dense which also provides excellent cover for birds and rabbits. Typically, the fruits/nuts are left for the wildlife to enjoy, but the nuts are edible. However, avoid nuts that have a bitter taste as they become toxic if eaten in abundance.

Foliage Color - Dark Green Features - Showy Flowers Flowering Season - Spring Growth Rate - Moderate Flower Color Group: Pink Plant Characteristics and Maintenance Light Needs: Full Sun (Flowers best in full sun) Water Needs - Low, Moderate (Fairly drought tolerant) Zone 3 Uses and Landscape Attributes Natural Garden Shrub Border Massing This a good small shrub for wildlife browsing. This shrub is very dense which provides excellent cover for birds and rabbits. Red Rugosa Rose – Non-Native Species Rosa rugosa Description: These roses are valued for their great hardiness and fragrant, recurrent blooms. Their characteristic foliage is deeply veined and crinkly green. They produce red flowers, 3-4 inches wide with a strong fragrance. Fall foliage color is orange/red. Large orange/red fruit display in fall. Form Mature Height: 5-7 Feet Width: 4 feet to 6 feet Bloom Season: late June - August Bloom Color: Red Extremely hardy Zone 2 Physical Characteristics and Maintenance Light: Prefers full sun but can handle partial shade Moisture: Prefers a moist, well-drained soil, but can tolerate dryness Soil Requirements: Rugosa roses prefer a rich, well-draining soil with slight acidity of around 5.6 to 6.5 soil pH. However they are very forgiving and can tolerate poor soil, clay and all kinds of abuse. Planting: Rugosa roses establish best when there is little competition from weeds and nearby plants. They adapt best if planted in the spring and kept well watered. Maintenance: They are known as “rugged” roses because they can be virtually maintenance free. The durable Rugosas have little need for fungicides; it is better to avoid spraying and possible damage to the foliage. Pruning: Prune in spring. How much to prune Rugosa roses depends on how large you want them to be. You can prune them to almost ground level in the spring if you want to keep it small. If you want a large, natural looking bush, you can do minimal pruning of old wood and suckers. As with all roses, don’t prune if a frost is anticipated within 6 weeks, to avoid winter dieback Uses and Landscape Attributes They can be grown as attractive hedges as their dense foliage develops nice fall color and most varieties carry large hips through the winter Attracts honeybees and other pollinators Siberian Larch – Non-Native Species Larix sibirica Description Larches are conifers in the genus Larix, in the family Pinaceae (Pine Family). The needles turn yellow and fall in the late autumn, leaving the trees leafless through the winter. It is a medium to tall size deciduous tree, with a straight, gradually tapering trunk and narrow open crown of many irregularly arranged, slender, somewhat horizontal branches. Form Tree grows up to 80 ft tall Needles: deciduous (fall off during winter) Bark: scaly, resembling that of a spruce tree, but the inner bark of larch is a vivid reddish purple. Fall Color: needles turn yellow in fall before dropping off Plant Characteristics and Maintenance It is hardy to zone 1 and is not frost tender. Soil Requirements: Adaptable to most soil types and pH levels, although it prefers an open airy position in well-drained soil. Lighting: It can grow in semi-shade (light woodland) or full sun. Watering Needs: It prefers moist soil. Plants are intolerant of badly drained soils Plants transplant well, even when coming into growth in the spring The Siberian Larch can live up to 100 years. Tundra Rose – Native to Alaska Potentilla fruticosa Description The Tundra Rose is a small, dense, deciduous shrub with numerous upright branches. The plant leafs out in the early spring. It produces yellow 1”-1.5” buttercup flowers from June until first frost, attracting pollinators all summer long. In the fall, the foliage turns a yellow-brown color, providing a variety of visual appeal. The Tundra Rose grows relatively slowly and is very hardy. Form Mature Height: 3-4 feet Width: 3-4 feet Bloom Season: June-first frost Bloom Color: Yellow Zone 2 Plant Characteristics and Maintenance Easy to grow Easily transplanted Soil requirements: adaptable to many types of soil Does well in extremely cold temperatures Lighting: full sun is best, tolerates partial shade Maintenance: to keep dense round habit, remove canes during winter or cut to ground Uses and landscape Attributes Wildlife: Attracts Butterflies
