The Primrose Path

What happier choice of blossoms to start a spring garden than primroses? Even the Latin name comes from primus, meaning the first. This is a large family of plants having 400 to 500 species, mostly occurring in the Northern Hemisphere. Some are hardy garden species and others are only for heated greenhouses. Only a few are well adapted to the long, hot, dry summers of most parts of California.

The most popular are the polyantha hybrids, often called “English primroses”, which do very well in this area. Planted in a good location, they will come back year after year, larger and more floriferous each time! Flowers have just about the widest range of colors possible: white, yellow, gold, orange, pink, red, maroon, blue or purple, and often have yellow centers, called eyes. Planted as a mixture they are a dazzling display for three or four months of the year: January through April.

All primroses have leaves that stay close to the ground and are arranged in a circle and in the center is a flower stems that rise up above the leaves. The new ‘SuperNova’ primroses flower atop 6-8-inch-tall stems with a cluster of bright-colored flowers. Individual flowers are an inch across and clusters contain a dozen or more. A colorful new line of primroses are called ‘Primlet’. They features clusters of smaller double flowers that are tightly held like rosebuds, leading to the common name rosebud primrose. They are a fine choice for a small container.

Primroses are best appreciated right at your feet, where you can enjoy their perfection at close range. Plant them along a path for a colorful walkway. Suitable primrose companions for a moist, partly shaded spot include astilbes, ferns, hostas, forget-me-nots, and Bethlehem sage.

Provide primroses with rich, woodsy soil enriched with compost, humus, peat moss and well-rotted manure. Choose a place in the shade, in a woodland garden, or in a spot that gets sun in the winter and shade from trees in the summer. Make sure you can water them throughout the summer. A little mulch will help keep the soil moist beneath them. Under native oaks, it is better to plant them in flower boxes or barrels so that you don’t overwater the oak trees in the summer.

Cut off old flower stems as flowers fade and trim off tattered leaves to keep your primroses looking their best. Plants will continue to produce new flowers through April. Give them a light feeding after bloom to strengthen the plants, and mulch them through the summer. When the clumps become thick and overgrown, divide them in May, every 3 or 4 years.

If you don’t want to use primroses as perennials, they also make lovely annual bedding plants. They are available during the winter and spring months and make a colorful display.

Disease-Resistant Fruits

Wet spring weather is prime time for diseases of all kinds, which can make leaves unsightly and even damage flowers. But it is especially hard on fruit trees causing diseases that last into the summer and damage the fruit as well as the foliage.

Spraying is typically done through the springtime to inhibit disease spores, but an even more successful way is to plant disease-resistant varieties. This is particularly beneficial for apples, which are prone to scab and cedar-apple rust; pears, which are prone to fireblight; peaches, which are prone to peach leaf curl; and apricots, which are prone to brown rot.

One of the best apple varieties for disease resistance is ‘Liberty’. This dark red apple has yellowish flesh that is crisp, juicy and fine flavored. It is primarily a dessert apple and it makes a fine pinkish applesauce. It is not susceptible to scab and very resistant to other apple diseases.

Other apples that are resistant to scab are ‘Golden Russet’, with crisp, aromatic, creamy yellow flesh and excellent sweet flavor; and ‘York Imperial’, a crisp, juicy apple with semi-sweet flavor that is a good keeper. ‘Empire’, a sweet and juicy red apple, and ‘Spartan’, with pure white, crisp, juicy flesh, are resistant to both fireblight and scab. ‘Stayman Winesap’, a late red apple with a lively flavor, is resistant to fireblight. ‘Honeycrisp’, a sweet, crisp apple, has some resistance to scab.

Some years, when the weather is just right, we can have a bad problem with fireblight on pears. It is a good idea to plant at least one resistant variety. Look for ‘Harrow Delight‘, with fruit similar to ‘Bartlett’, and ‘Warren’, whose smooth flesh is juicy and buttery with superb flavor. ‘Magness’, with soft, juicy, sweet flesh, and ‘Moonglow’, a large fruit for fresh use or canning, are also fireblight resistant.

Asian pears, which have round, juicy, crisp-like-an-apple fruit, can also be attacked by fireblight. ‘20th Century’, with sweet, mild-flavored fruit, and ‘Shinko’, with sweet, flavorful fruit, are both resistant to fireblight.

Peach trees can be severely damaged by peach leaf curl. ‘Frost’ peach is a delicious, medium-sized yellow freestone that is very resistant. So is ‘Q-1-8’, a semi-freestone white peach that is sweet and juicy with a sprightly flavor, and ‘Indian Free’, a white peach with red streaks through the fruit. It is tart until fully ripe when it develops a rich, distinctive flavor.

Apricots can have trouble with brown rot, which causes fruit to rot on the tree forming mummies. It is a problem when we have moderate temperatures and moist weather during bloom. ‘Harcot’, which has medium to large fruit with a sweet, rich flavor, is resistant to this disease.

Your orchard will be easier to maintain if you choose disease-resistant varieties whenever you can.

Berry Cousins

Lingonberries have been a gourmet staple in Sweden, Norway and Germany since the time of the Vikings. Europeans are wild about lingonberry jams, juices, syrups and liqueurs. For a pancake syrup, their flavor is excellent. Also known as mountain cranberry or foxberry, this berry is little known in this country.

The pea-sized fruits have a strong red color and a tasty, tart flavor. They have unusually good keeping qualities, up to 8 weeks under refrigeration. Berries and leaves of the bush are used for medicinal purposes and, eaten raw, they are good for the digestion.

The lingonberry, Vaccinium vitis-idaea, is a wonderful ornamental plant. The bright red berries and bright evergreen foliage make it attractive year-round. It is a creeping, ground-cover plant growing 12 to 16 inches tall. It needs constant moisture and partial shade and will make a handsome ground-cover under rhododendrons. They are closely related to cranberries and blueberries.

In Northern Europe the lingonberry is found commonly growing in the pine forests. It is very hardy, and prefers a cool location. They also like an acid and gritty soil with a pH of 4 to 5. When planting, amend the soil with generous amounts of peat moss and sand and be sure the soil is well-drained. When given the right conditions, they will form a solid mat which shades the ground and provides its own mulch.

The pinkish white, bell-shaped flowers come in clusters in early spring and produce dark red berries which ripen by late spring or early summer. The plants are very disease-resistant.

Lingonberries also make attractive container plants. As a potted ornamental, it fruits in the fall of the year, and the red berries set against the green foliage are very showy. Find a spot in your garden for this intriguing, edible landscape plant.

A close cousin to the lingonberry is our native huckleberry, Vaccinium ovatum. This lovely shrub has small shiny leaves that are dark green above and pale green underneath, with copper-colored new growth. The spring flowers are particularly attractive. They hang like clusters of pink, urn-shaped bells very much like heather or manzanita blossoms, to which they are related.

Huckleberries make excellent landscaping plants since they have such attractive, glossy, evergreen foliage and showy edible fruit. They are good for anchoring soil and flourish in sun or shade with some summer watering and good drainage. They like acidic soil that is low in organic matter, and tolerate everything from sandy soils to clay, and are drought tolerant once established. One inch of organic mulch will keep them happy.

Evergreen huckleberries are excellent plants for creating wildlife habitats. The flowers attract butterflies and the berries are eaten by scarlet tanagers, bluebirds, thrushes, and other songbirds. Deer and rabbit browse freely on the plants. Because of their food value to wildlife and their dense shrubby growth, evergreen huckleberry is a good addition to hedgerows.

In fall, the plants are covered with delicious, juicy, purplish-black berries. They are delicious fresh and also make excellent jelly, pies, pancakes and muffins. They can also be frozen and used for up to 6 months.

Edible plants can be important additions to your landscape, providing beauty as well as tasty and healthy treats for your family.
