Fernleaf Peony, Perennial Of The Day

Paeonia tenuifolia 'Rubra Flora Plena'
Fernleaf Peony


Type Perennial
Hardy range 3A to 8A
Height 12" to 15" / 30cm to 40cm
Spread 12" to 24" / 30cm to 60cm
Growth rate Average
Form Rounded
Exposure Partial shade or partial sun to full sun

Bloom Color Red
Bloom Time Spring

The flowers are fragrant, very showy, suitable for cut flowers and suitable for dried flowers.

Environment
This plant will grow in moist soil.
Suitable soil is well-drained/loamy or sandy.
The pH preference is a neutral soil.

Leaf Color Green

This plant has attractive foliage.

Culture Notes
When planting Paeonia, place the "eyes" of the roots between 1"-2" below the surface. Needs partial shade in hotter climates. Some of these plants that have heavy blooms may need staking to support the blooms. The buds of this plant attract ants, and it is thought that the ants help the buds open. Peonies should be planted in areas with good air circulation. However, established plants are best left undisturbed. Avoid watering overhead when the plants are setting buds. Removal of the lateral buds on the stem will allow the single flower to grow larger. Remove flower heads as soon as they start to fade. In autumn remove foliage to ground and destroy it. Do not compost this to prevent the spread of disease. When preparing the planting bed, incorporate equal amounts of composted oak leaf mulch and coarse sand to your soil. Some plants will want a small amount of lime added to the soil.

'Rubra Flora Plena' has deep red, double flowers and fernlike, deep green foliage.

Planting Ideas For 2011

Rhododendron (subgenus Rhododendron) 'Kristin Marie'
Rhododendron

Type Shrub, woody plant
Hardy range 5B to 7B
Height 6' to 8' / 1.80m to 2.40m
Spread 6' to 10' / 1.80m to 3.00m
Growth rate Slow
Form Rounded
Exposure Partial shade or partial sun
Persistence Evergreen
Bloom Color Pink and white
Bloom Time Spring and Summer
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 (less than 6.8) soil.

Leaf Color Green
Fall Color No change in fall color

Culture Notes 

Partially shaded location gives good growth, provided drainage is adequate. Roots rot in soil that drains poorly. I (Dr. Gilman) have had no trouble transplanting these plants balled in burlap, although many are grown in containers. Pinch back the flowers after they have faded to eliminate the brown developing fruit if you wish. However, this is not essential for good flowering the following year. After all, these plants have been flowering quite nicely without our intervention. This plant is considered mostly allergy free and causes little or no allergy problems in most people. Organic amendments in the backfill help establish plants quickly by encouraging roots to grow out of the container and into backfill soil.

Rhododendrons are ornamental, ericaceous, broad-leaved evergreens. Azaleas belong to this genus, but many are not evergreen. They grow best in shade or partial shade. A south or southwest exposure increases the chance of winter injury to evergreen types when grown in northern climates. Plant in an acidic, moist, well-drained soil with a pH between 4.5 and 6.5. Transplanting balled and burlapped or potted plants is most successful. The shallow root systems are easily injured by deep cultivation, but benefit from mulching.
Plants fail to absorb iron and have yellow leaves with green veins if the soil is not sufficiently acidic. Finely ground sulphur can be added to the soil to increase acidity. Have the soil tested before planting in order to determine the pH. Apply a 2:1:1 N:P:K ratio fertilizer two or three times each year before and after blooming and perhaps again as plants enter dormancy - timing is not as critical as previously believed. Prevent winter burn in northern climates by avoiding exposed planting sites and by shading during winter.

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.



Acer palmatum 'Pixie'
Japanese Maple
Type Shrub, woody plant
Hardy range 5B to 8A
Height 8' to 12' / 2.40m to 3.60m
Spread 10' to 15' / 3.00m to 4.60m
Growth rate Slow
Form Rounded and spreading or horizontal
Exposure Partial shade or partial sun to full sun
Persistence Deciduous

Bloom Color Red
Bloom Time Spring

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 (less than 6.8) soil.

Leaf Color Purple
Fall Color Red

This plant has attractive foliage and attractive fall colors.

Culture Notes 

This large shrub or small tree tends to leaf out early, so it may be injured by spring frosts. Protect them from drying winds and direct sun by providing exposure to partial or filtered shade and well-drained, acid soil with plenty of organic matter, particularly in the southern part of its range. Leaves often scorch in hot summer weather in USDA hardiness zones 7b and 8, unless they are in some shade or irrigated during dry weather. More direct sun can be tolerated in the northern part of the range.

Be sure drainage is maintained and never allow water to stand around the roots. Grows fine on clay soils as long as the ground is sloped so water does not accumulate in the soil. Responds well to several inches of mulch placed beneath the canopy. Not for western Texas or western Oklahoma but grows well in the shade in Dallas/Fort Worth.

Maintain adequate mulch area


Solenostemon x syn. Coleus x hybridus 'Kaleidoscope'
Coleus
Type Perennial
Hardy range 9B to 11
Height 12" to 18" / 30cm to 45cm
Spread 8" to 12" / 20cm to 30cm
Growth rate Fast
Form Upright or erect
Exposure Full shade to partial sun
Persistence Evergreen

Bloom Color Blue and white

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

Leaf Color Green, pink, purple and variegated
Fall Color No change in fall color

This plant has attractive foliage.

Culture Notes

 These plants are usually grown as annuals in cooler zones, but can be perennials in frost free areas. Flowers can be left on these plants, but removing them will help the plant maintain its bright foliage. Once plants begin to flower, even the new shoots that develop after pinching produce flowers. This signals that it is time to begin thinking about replacing the plants with new ones. The foliage of Coleus plants looks great when arranged with freshly cut flowers.


Cryptomeria japonica 'Globosa Nana'
Japanese Cedar, Sugi
Type Tree, woody plant
Hardy range 6A to 8A
Height 6' to 8' / 1.80m to 2.40m
Spread 4' to 8' / 1.20m to 2.40m
Growth rate Slow
Form Oval and pyramidal
Exposure Full sun
Persistence Evergreen

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

Leaf Color Blue and green
Fall Color Copper

Crown, Branch and Twig

This plant is symmetrical with a fine texture and has a dense crown.
This plant's bark is showy.
Branches or twigs are of medium thickness.
This plant is often grown with multiple trunks.

Culture Notes

 Provide an acid soil and protection from winter winds. Locate the tree so air circulation is good, particularly during summer to help prevent leaf blight. Best with afternoon shade in southern part of its range. A number of cultivars are available varying in growth habit and ability to hold green foliage color in the winter. This one is very slow growing, and remains small and mostly green in winter.
 
Cryptomeriais tolerant of compacted soil and performs well in parking lots and other tough, urban sites with some irrigation in drought. It makes a wonderful accent, screen, or border tree for larger properties. This one remains small so it is well suited for residential landscapes.
Planting and establishing shrubsThe 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.

Hyacinthus orientalis 'Jan Bos'
Hyacinth

Type Perennial
Hardy range 3A to 7A
Height 6" to 10" / 15cm to 25cm
Spread 3" to 5" / 8cm to 13cm
Growth rate Slow
Form Upright or erect
Exposure Full sun
Persistence Deciduous

Bloom Time Spring

The flowers are fragrant and suitable for cut flowers.

Environment 
This plant will grow in dry to moist soil.
Suitable soil is well-drained/loamy or sandy.
The pH preference is a neutral soil.

Leaf Color Green

Culture Notes 

Bulbs should be purchased and planted in late autumn. Once the tubular flowers are finished in the spring, they should be removed. Feed the bulb generously until the foliage goes dormant in the summer. In colder climates, mulch to protect from the cold winters. Often the bulbs will not bloom as well in later seasons. Hyacinths are more commonly used as forced plants, and the plants are discarded after the plant goes dormant.

Culture Notes
Purple Trumpet Tree is one of the most beautiful trees in flower in the world!  Its bright blooms fill the sky in spring with a gentile pink color for several weeks.  All foliage drops from the tree just before it flowers.  This is normal and is not a cause for concern.  Plants flowers and grow best in full sun.  Branches often form included bark in the crotches.  This can cause the branch to split from the trunk as it grows older.

Purple Trumpet Tree can be grown in full sun or partial shade on any reasonably fertile soil with moderate moisture.  Trees should be protected from frost.It is one of the most beautiful trees in flower which has a place in most landscapes. This tree appears to tolerate urban conditions well having survived in parking lot islands, buffer strips, and in other areas with limited soil space.  Trees are well suited for planting in parking lot islands and other small soil spaces. Once trees are established trees in Florida (50 - 65 inches of rainfall each year) they have grown fine without irrigation. Trees are considered fairly good compartmentalizers of decay.

Use as a street tree

Thinking Landscape






Walkways in Design

By Steve Chepurny*

            Walkways and or pathways require careful consideration when contemplating an entrance approach or a simple means of egress to a point of interest or activity.  A path that is too long immediately will give the impression to your guests as overwhelming and uncomfortable.  We all appreciate curb appeal, and the entrance walk is the first approach or perhaps the exterior hallway to a property.  A comfortable walk that takes into account the average person’s stride and how steps are carefully integrated into the journey are critical components in a person’s perception of a home. Often steps are carelessly placed and blind spots exist, which creates an internal sense of discomfort.  Human nature wants to have a firm understanding of how to get from point “A” to point “B’ with a sense of ease, safety and most of all comfort. 
 
            Lighting is a critical component to make the journey safe and enjoyable.  It’s best to avoid hot spots in lighting unless safety is a critical concern.  An entrance lamppost with an address posted can create a sense of identity while providing a quaint feel to the property. When possible, integrate soft lighting from above, possibly mounted 25’ to 35’ high in a tree to create a soft moonlight feel with dappled shadows as soft accents.  If mature trees don’t exist, try mounting low profile lights in the soffit of the home, which can be directed to guide a person along the walk.  It’s important to have the light vary in intensity from very soft to brighter where needed at points of interest or change of grade.  Avoid the runway effect at all costs, however, which means far too much lighting. If energy efficiency is desired, try using an LED lighting system, which has a tremendous lamp life expectancy and very low energy consumption.  However, the initial cost can add 15 percent to 25 percent to the cost of project, but it’s less expensive in the long run. 

            Balance is key to deciding the width of a walk, and should take into consideration the house first, property size second and lastly the surrounding landscape. There is no right or wrong choice, but a feeling of comfort within the space is the desired goal. Typically, I recommended width of a walk should be no less than 48” for two people comfortably and should expand or vary in width at points of congregation, entrance ways, or points of interest.  A change in material selection at the entrance or point of interest is a great way to create some diversity in the walk and pattern.  I typically recommend the walk entrance be approximately 6’ to 8’ and gradually taper to a width of no less than 4’.   
           
           Drainage should also be a careful consideration in designing a walk.  If the walk collects or holds water after a rain, it’s been poorly designed.  Often flower beds line a walk with little consideration on how to move water off of the walk.  This problem can turn very quickly into a liability for the homeowner and landscape architect or designer if the water freezes and ices over in the winter.  Deicers can be used but often will quickly degrade a surface, including concrete, if used in excess.  Landscape and plantings can abut a path and add tremendous interest if sited appropriately to accommodate water runoff without impeding site lines. A surface with some texture will always perform better in both rain and snow than a product that’s smooth with little texture. 
           
           The choice of the material is yet another critical design factor in any walkway.  I typically like to have the walkway integrated with the architectural materials that are used on the home. If integration isn’t possible, a product that has a soft compliment as opposed to a glaring contrast will typically create a pleasant approach with a sense of visual pleasure to those strolling.  In choosing and selecting materials, favor local stone products such as bluestone or a classic brick. Natural materials are often timeless and the best choices. Some good examples: Clay brick is offered in a multitude of color ranges and styles so it adds a warm feel to any path; concrete pavers offer great selections in size, colors, and texture. Cost and budget always plays a critical component in selection.  A typical walk in concrete pavers can average about $15 per square foot to $16 under normal conditions. Clay products are typically in line with concrete products.  Natural stones may cost anywhere from $2 a square foot to $4 in addition to pavers. Having a budget upfront is key! You don’t want to waste time considering products that are just too expensive or high maintenance.  A knowledgeable landscape architect or designer will help you navigate through this maze.  By the same token, don’t settle for a product that won’t achieve all the above needs and possibly become a negative down the road. Wait, if need be, until your budget affords the proper designer, material and installation contractor.  

            Always consult a licensed professional to design and construct your walk.  It’s the first approach to your home and will add character and warmth for years to come.  A carefully blended walk with flowering shrubs, perennials, grasses and perhaps a small water feature will incorporate a harmonious path in your yard that will bring visitors to your door or patio with a big smile.
