James Macfarlane Lilac Featured Plant of The Day

 Syringa x prestoniae 'James Macfarlane'
    Lilac

Type    Shrub, woody plant
Hardy range    3B to 7B
Height    8' to 12' / 2.40m to 3.60m
Spread    8' to 12' / 2.40m to 3.60m
Growth rate    Fast
Form    Rounded and vase shaped
Exposure    Partial shade or partial sun to full sun
Persistence    Deciduous

Bloom Color    Pink
Bloom Time    Spring

The flowers are fragrant and very showy.

 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 slightly alkaline (less than 6.8 to 7.7) soil.

Leaf Color    Green
Fall Color    No change in fall color

 Culture Notes
Lilac is a common flowering shrub that grows best in a sunny location.  The plant will grow in shade but flowering is poor and powdery mildew is likely to be severe.  The growth rate is rapid and the plant produces many suckers. Pruning should be completed after flowering and by late spring to ensure next year's flower buds are not removed. Pollen bothers certain people.

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.

True Lavender, Featured Plant of The Day

Lavandula angustifolia 'Hidcote'
    English Lavender,  True Lavender

Type    Shrub, woody plant

Persistence    Deciduous and semi-evergreen

 
Bloom Color    Purple
Bloom Time    Spring and Summer

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

 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 a neutral to slightly alkaline (6.8 to 7.7) soil.

 Leaf Color    Green and silvery
Fall Color    No change in fall color
This plant has attractive foliage and fragrant foliage.

 Culture Notes
Prune plant after flowers bloom to keep it compact and to promote vegetative growth.  Shear back in spring to create denser plants.  In the spring, remove dead foliage only.  Deadhead spent flowers after blooming. Lavandula angustifolias lose their vigor after several years and will need to be replaced with new plants.  Plants prefer a well-drained, sunny position.  Plants go well with: Santolina, Dianthus, Armeria, Lychnis, and Thymus sp.  Plants serve as butterfly nectar sources.

If there is a lot of winter damage, cut plant back by 1/3.

Amity Wilson Japanese Camellia, Featured Plant of The Day


Camellia japonica 'Amity Wilson'
    Japanese Camellia


Type    Shrub, woody plant
Hardy range    7A to 9A
Height    10' to 15' / 3.00m to 4.60m
Spread    6' to 10' / 1.80m to 3.00m
Growth rate    Slow
Form    Oval
Exposure    Partial shade or partial sun to full sun
Persistence    Evergreen

Bloom Color    Pink
Bloom Time    Spring and Fall

The flowers are very showy.

Environment
This plant tolerates some drought and a little salt.
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    Green
Fall Color    No change in fall color
This plant has attractive foliage.

Culture Notes
Camellia is the state flower of Alabama.  It is natural for some flower buds to drop, and it should not cause too much concern, because Camellias set more buds than they can open.  Sometimes bud drop can be caused by overwatering, but even more by underwatering, especially during summer, or by spells of very low humidity. Excess fertilizer can prolong the growth period and make the plant more susceptible to cold damage. However, best performance of plants occurs with regular applications up to four times per year. Soil with a pH less than 7.0 is best. Camellia pollen causes few if any allergy problems.

Maintain adequate mulch area

Clear all turf away from beneath the branches and mulch to the drip line, especially on young trees, to reduce competition with turf and weeds. This will allow roots to become well established and keep plants healthier. Prune the tree so trunks and branches will not rub each other.  Remove some secondary branches on main branches with included bark.  This reduces the likelihood of the main branch splitting from the tree later when it has grown to become an important part of the landscape.  Locate the tree properly, taking into account the ultimate size, since the tree looks best if it is not pruned to control size. The tree can enhance any landscape with its delightful spring flush of foliage. It can be the centerpiece of your landscape if properly located.

Transplant in winter during full bloom when the other parts of the plant are dormant.

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.
