Deciduous Shrub Of The Day

Abeliophyllum distichum
White Forsythia
Type Shrub, woody plant
Hardy range 5A to 9A
Height 36" to 5' / 90cm to 1.60m
Spread 6' to 8' / 1.80m to 2.40m
Growth rate Average
Form Spreading or horizontal and vase shaped
Exposure Partial shade or partial sun to full sun
Persistence Deciduous

Bloom Color White
Bloom Time Spring and Winter
The flowers are very showy.

Environment This plant will grow in moist soil.
Suitable soil is well-drained/loamy or sandy.
The pH preference is an acidic to alkaline (less than 6.8 to more than 7.7) soil.

Leaf Color Green

Culture Notes In cool coastal areas, plant near a warm wall to encourage flowering. Prune as soon as flowers fade to maintain vigor and encourage bloom. Every few years prune hard nearly to the ground. Plants in sun or partial shade grow and flower respectfully. Flowers are light pink appearing almost white on twigs produced a year earlier; you may want to wait to do any substantial pruning until after you enjoy the flower display. Flower pollen can cause allergy in some people. Twigs often root as they touch the ground.


Planting and establishing shrubs
The most common cause of young plant failure is planting too deep. Plant the root ball no deeper than it was in the nursery. In most instances, the root flare zone (point where the top-most root in the root ball originates from the trunk) should be located just above the landscape soil surface.
Sometimes plants come from the nursery with soil over the root flare. If there is soil over this area, scrape it off. The planting hole should be at least twice the width of the root ball, preferably wider. In all but exceptional circumstances where the soil is very poor, there is no need to incorporate anything into the backfill soil except the loosened soil that came out of the planting hole. Never place ANY soil over the root ball. If a row or grouping of plants is to be installed, excavating or loosening the soil in the entire bed and incorporating organic matter enhances root growth and establishment rate.

Weed suppression during establishment is essential. Apply a 3-inch thick layer of mulch around the plant to help control weed growth. Keep it at least 10 inches from the trunk. If you apply it over the root ball, apply only a one or two inch layer. This allows rainwater and air to easily enter the root ball and keeps the trunk dry. Placing mulch against the trunk or applying too thick a layer above the root ball can kill the plant by oxygen starvation, death of bark, stem and root diseases, prevention of hardening off for winter, vole and other rodent damage to the trunk, keeping soil too wet, or repelling water. Regular irrigation through the first growing season after planting encourages rapid root growth, which is essential for quick plant establishment.

Deciduous Shrub Of The Day

 
Philadelphus x lemoinei
Mock Orange

Type Shrub, woody plant
Hardy range 5A to 8A
Height 4' to 8' / 1.20m to 2.40m
Spread 8' to 12' / 2.40m to 3.60m
Growth rate Average
Form Rounded and upright or erect
Exposure Partial shade or partial sun to full sun
Persistence Deciduous

Bloom Color White
Bloom Time Spring

The flowers are fragrant and very showy.

Environment This plant tolerates some drought.
This plant will grow in dry soil.
Suitable soil is well-drained/loamy, sandy or clay.
The pH preference is an acidic to slightly alkaline (less than 6.8 to 7.7) soil.

Leaf Color Green
Fall Color No change in fall color



Culture Notes A sight to behold and smell in full bloom, plants perform best in full sun in moist soil. Like many garden plants, those supplied with some organic matter in the root zone before planting make the best growth. Plants offer little after they flower. Might be best located in a shrub border where the plant in smelled but not seen for most of the year. Flowers are extremely fragrant compared to other Philadelphus. This plant is considered mostly allergy free and causes little or no allergy problems in most people.

Philadelphus will not flower following annual hard pruning because plants flower on last year's growth.

Perennial Of The Day

 
 
Galanthus nivalis
Common Snowdrop

Type Perennial
Hardy range 3A to 9A
Height 4" to 6" / 10cm to 15cm
Spread 6" to 10" / 15cm to 25cm
Growth rate Average
Form Upright or erect
Exposure Partial shade or partial sun to full sun
Persistence Deciduous

Bloom Color White
Bloom Time Spring and Winter
The flowers are fragrant.

Environment This plant will grow in moist soil.
Suitable soil is well-drained/loamy or sandy.
The pH preference is an acidic to neutral (less than 6.8 to 7.2) soil.

Leaf Color Green

Culture Notes Plant in sun to partial sun, avoid wet soils, and do not allow the soil to stay dry during the summer. Usually plant in groups or large masses. Fall is the time to plant new bulbs, and just after the honey-scented flowers fade is the time to divide and move the plants. A good winter chill is important for good growth and blooms.
