Perennial Of The Day

Tricyrtis hirta 'Miyazaki'
Toad Lily, Japanese Toad Lily

Type Perennial
Hardy range 4A to 8A
Height 24" to 36" / 60cm to 90cm
Spread 18" to 24" / 45cm to 60cm
Growth rate Average
Form Upright or erect
Exposure Full shade to partial sun
Persistence Deciduous

Bloom Color Purple and white

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

Leaf Color Green

This plant has attractive foliage.

Culture Notes Toad lilies are grown primarily for their unusual spotted blossoms. They self-sow easily, and stem cuttings taken in the summer are easily rooted. These plants prefer a moist, well-drained soil and are able to tolerate a half day of sun. In the spring, cut away dead foliage only. Deadhead spent flowers after blooming and, in the fall, cut back to the ground. 'Miyazaki' is noted for its white lily-like blossoms that are heavily spotted in purple. This is an excellent plant for those shaded areas of the garden.

Vine Of The Day



Campsis grandiflora
Trumpet Vine

Type Vine
Hardy range 7A to 10A
Height 25' to 50' / 7.60m to 15.20m
Spread 40' to 50' / 12.20m to 15.20m
Growth rate Fast
Form Spreading or horizontal, variable height and variable spread
Exposure Partial shade or partial sun to full sun
Persistence Deciduous

Bloom Color Orange and yellow
Bloom Time Summer

The flowers are very showy.


Environment This plant tolerates drought and occasional wetness.
This plant will grow in very dry to occasionally wet 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 Yellow


Culture Notes Like many vines, Trumpet Vine flowers best in a full sun location. It grows but flowers poorly in a shaded location. It will do fine in any soil except those kept continually wet and flooded. Trumpet Vine climbs to 30 feet or more when given support. The brilliant orange flowers are borne in summer and are often visited by hummingbirds. They will hang down from an arbor or trellis making a wonder "wall" or "ceiling" in a garden. Rapid growth makes training easy, but regular pinching and pruning is required to establish this vine on a structure. This hybrid is wonderful in flower.

This plant is related to the native Campsis but is much less aggressive. 'Morning Calm' bears coral flowers. This plant is considered mostly allergy free and causes little or no allergy problems in most people.

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. 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.

Day Of The Clematis Vine

Clematis (lanuginosa x group)(n) 'General Sikorski'
Clematis
Type Perennial, vine
Hardy range 3B to 9A
Height 8' to 10' / 2.40m to 3.00m
Growth rate Average
Form Upright or erect
Exposure Partial shade or partial sun to full sun
Persistence Deciduous

Bloom Color Lavender
Bloom Time Summer and Fall

The flowers are showy.

EnvironmentThis plant tolerates some drought.
This plant will grow in moist soil.
Suitable soil is well-drained/loamy or sandy.
The pH preference is a neutral to slightly alkaline (6.8 to 7.7) soil.

Leaf Color Green
Fall Color No change in fall color


Culture NotesThese vines prefer cool, rich, moist, relatively acidic, well-drained soils, and one should never allow these plants to become too dry. They need to be placed in an area of the landscape that receives full sun. These plants will do better if they are mulched with a shallow-rooted ground cover.
If being used on a trellis, it's best if, in the spring, you add compost or cow manure to the base of this plant. Also add a water soluble fertilizer (15-30-15) every two weeks through May, June and July.


 
Clematis (patens x group)(n) 'Bee's Jubilee'
Clematis  
Type Perennial, vine
Hardy range 4A to 8A
Height 8' to 15' / 2.40m to 4.60m
Spread 8' to 12' / 2.40m to 3.60m
Growth rate Slow
Form Spreading or horizontal and variable spread
Exposure Partial shade or partial sun to full sun
Persistence Deciduous

Bloom Color Blue and pink
Bloom Time Spring and Summer

The flowers are showy and suitable for cut flowers.


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


Leaf Color Green

Culture Notes Most Clematis are hybridized and do not come true from seed. Stem cuttings can be taken early summer. Removing spent flowers often increases the blooming period. 'Bee's Jubilee' requires no pruning. Plant so that the roots are shaded.

Since Clematis do not climb by tendrils or aerial roots, their leaf petioles will twine around anything close by (including themselves) for support. Clematis are beautiful specimens climbing up (with proper support wires, etc.) a fence, trellis, lamp post or wall. It's best not to plant Clematis in an area where it would have to fight for its water supply, such as next to the roots of a tree. 'Bee's Jubilee' is a woody climber and shows good performance if its exposure is facing south and west. Although a weak climber, its blooms remain even when the plant begins browning. The 6-8" blooms of 'Bee's Jubilee' are a mauve bluish-pink, with a darker pink stripe running through each petal. This makes for a beautiful flower.



Clematis 'Multi Blue'
Hybrid Clematis

Type Perennial, vine
Hardy range 3B to 9A
Height 8' to 12' / 2.40m to 3.60m
Growth rate Average
Form Spreading or horizontal and variable spread
Exposure Partial shade or partial sun to full sun
Persistence Deciduous

Bloom Color Purple
Bloom Time Spring through Fall

The flowers are fragrant and showy.

Environment This plant tolerates some drought.
This plant will grow in moist soil.
Suitable soil is well-drained/loamy.
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 Multi Blue has fully double blooms, nearly 5 inches across. These vines prefer cool, rich, moist, relatively acidic, well-drained soils, and one should never allow these plants to become too dry. Many need to be placed in an area of the landscape that receives full sun but allows the roots to remain cool. To keep the roots cool, spread several inches of an organic mulch for several feet around the main stem. Prune these vines after flowering, if desired, to maintain the plant's general shape.

They can be planted at the base of any support. The best time to plant in the north is spring. Cutting back young plants about one-half will encourage branching and lead to larger flowers. Prune spring flowering plants (those that bloom on previous season's growth) only to remove dead branches and to control the plants size.
