Blue Oat Grass

Helictotrichon sempervirens
A handsome, non invasive clumping, evergreen grass with stiff, light blue-gray foliage and golden oat like blooms in summer. It reaches up to 2 x 4 feet ( with flowers up to 4 feet in height ). Blue Oat Grass is native to mountains from southeast France to northern Italy. The foliage is fast to emerge in spring.
Prefers full sun in cool climates, partial sun in hot climates and is best in deep, alkaline to slightly acidic well drained soil. Hardy zones 3 to 8 and tolerant of drought, hail, heat, salt as well as wind & is not eaten by deer. Unfortunately excessive winter moisture can cause rot. Great for harsh climates, the Blue Oat Grass even grows in Winnipeg. Cut back before new growth begins during spring. New plants should be installed during early spring and kept moist until established.

Currants and Gooseberries

Ribes

A massive genus of around 150 species of shrubs native to northern temperate regions around the world. Many species are grown commerically for their fruit.
A tea can be made from boiling the leaves in 5 minutes. The newly emerging shoots during spring can be eaten raw.
The fruits of Currents are very rich in Pectin, Vitamin A, C, Calcum, Cooper, Iron and Potassium. Ssome of the better tasting species are good eaten fresh or in salads.
Cooking improves the taste of some types of Currents and they can be used in pies, muffins, juices, preserves and bread. A number of Ribes species are not self fertile and need to be planted in groups for good fruit production.
Currents prefer partial shade ( prefer light shade during the hottest part of the day ) on fertile, deep, cool, moist, well drained soil. Currents do not like hot soil and mulch is essential where soil bakes in the sun. Propagation is from seed, hardwood cuttings ( 10 inch lengths ) taken during autumn and layering. New plants should be installed during mid to late autumn or early spring while still dormant. Old leggy plants can be cut to the ground during early spring to renovate.
Many species are prone to a rust fungus that can also infect and kill species of White Pines. Due to Blister Rust disease, the Currents have been deliberately killed and in many places nearing extinction where White Pine is a commercial timber crop. The White Pine Blister Rust was accidently imported to North America during the early 1900s on shipments of White Pine seedlings that were interestinly grown in Europe. Close to 1.5 billion Currant plants have been destroyed over the past century in the panic to control White Pine Blister Rust. Some states still ban the cultivation of either all or certain species of Currants. Fortunately there are newer cultivars that are resistant to Blister Rust ( recommended article for Currant growers in New England...http://www.nhdfl.org/forest-health/white-pine-blister.aspx ).

Ribes x gordonianum ( Gordon's Currant )
The hybrid of Ribes odoratum & R. sanguineum. A tough, deciduous shrub, reaching up to 8 x 8 ( rarely over 5 x 6 ) feet.
The toothed, 3 or 5 lobed leaves, up to 2 inches in length, are deep green, turning to orangish-yellow in fall.

Ribes grossularia ( Garden Gooseberry )
The hybrids between Ribes uva-crispa & the mildew resistant native Ribes hirtellum.
The flowers are self-fertile so that multiple cultivars are not required for fruit set.
The tasty, succulent fruits are are great used in pies and cooking the fruits make the spines disappear. Plants mature quickly and up to 5 pounds of fruit can be expected during the third year.
Hardy zones 4 to 7 in full sun or partial shade in cool, moist, well drained soil ( their tolerance of partial shade makes them ideal for intercropping between fruit trees in orchards ). Their shallow, spreading rootsystem can get easily damaged by turf/weeds competition or vigorous cultivation so an organic mulch covering is preferred. Shredded hardwood mulch, chopped leaves or pine needles all make a good mulch. It is resistant to Gooseberry Mildew disease which devastates Ribes uva-crispa even in Europe where accidentally introduced. It is therefore valuable in breeding commercial Gooseberry hybrids. Pruning is generally done during the winter and is similar to pruning required for most bigleaf hydrangeas in removing stems 3 years or older at the base to make room for newer, more vigorous growth. Gooseberries should be planted at approximately 5 feet apart during the fall as growth is quick to begin during the spring. Propagation is done by layering of 10 inch branch cuttings. The cuttings are inserted in the soil with only the top bud left exposed.

Also called Ribes silvestre. An upright, deciduous shrub, reaching a maximum size of 6.5 x 5 ( rarely over 5 ) feet, that is native to western Europe ( from Netherlands & Belgium to Poland; south to Portugal to northern Italy ). It is locally naturalized in eastern North America to as far north as Sault Ste Marie and Tobermory, Ontario. Red Currants are good looking landscape plants and are the epitome of edible landscaping.

The yellowish-green flowers are borne in racemes, up to 3.2 inches in length, during spring. They are quickly followed by edible, translucent, scarlet-red fruits, up to 0.5 inches across, during mid to late summer. Each cluster contains from 3 to 10 berries. A single plant can produce up to 7 pounds of berries in a season. The plants are self pollinating so a single lone plant will bear fruit.
The stems are smooth and unarmed. The fruits are rich in Antioxidents, Vitamin B1, Vitamin c, Copper, Iron, Manganese, Phosphorus, Potassium. They can be eaten fresh, dried and are great used in jams, jellies, juices, sodas and tart fillings. Currant jelly can even by used as an antiseptic for cuts and burns.
Cultivars of Ribes rubrum make up most of the commercially grown Red Currents grown today. Birds also like the berries and netting may be necessary to protect your crop.
Hardy zones 3 to 7 ( tolerating as low as -40 F ) in full sun to partial shade on fertile, well drained soil with a preferred PH of 5.5 to 6.8. It is recommend to plant during early spring or autumn while dormant and mulch deeply during the first winter to protect from frost heaving.
Plants generally take about 4 years to fully establish and bear fruit heavily.
Pruning is generally to keep the plants compact and thin out enough to prevent leaf fungus, esp. mildew. Ribes rubrum is prone to White Pine Blister Rust and it may be illegal to plant it in areas where White Pine are commercial timber crops or a large part of the urban forest canopy.
Propagation of cultivars is from softwood and hardwood cuttings ( take cuttings during autumn, stick them in the ground, and they root by the following spring - very easy ). Another option is taking foot long cuttings of dormant wood during late winter, dipping in rooting hormone and potting in ordinary potting soil. The cuttings root quickly. Layering is also an option.
