Just When the Garden Needs a Punch of Color, Summer Phlox Delivers

IMG_0590

 

In the hot, humid days of the Philadelphia summer, there are dry, brown plants with bleached out colors. My July and August garden was boring. But, then I planted Summer Phlox (Phlox paniculata).

Summer Phlox is naturally a deep pink, but there are white varieties, too. In May, I trim it back to half  it’s height.  When it flowers, the plant it isn’t so tall it flops over.

Insects visit the plant for its nectar. I have found tiny bees and flies roaming around the flower petals.

Summer Phlox is a tough plant, blooming in dry, sun-drenched spots. I am so glad I planted it in my garden.

Phlox Paniculata

Zones: 3 to 9

Soil: moist

Sun: full sun to partial sun

Height: 36 to 60 inches tall

Growing: apparently grows easily from seed and will probably reproduce the species instead of the various colors of cultivated varieties

Natural range: southern New York to northern Georgia, west to Illinois, Missouri and Arkansas

 

 

 

 

 

 

 

 

 

 

Pollinator Syndromes: How to Predict Which Flowers Insects Will Like

Pollinators are those animals that give the invaluable service of helping plants reproduce and create seed or fruit that humans and others eat.

There are many pollinators including bats, bees, beetles, birds and butterflies.

The flower type, shape, color, odor, nectar, and structure vary and attract different pollinators according to the pollinators likes and needs. Such characteristics are pollination syndromes.

With this information you can predict which animals are most like to visit which plant.

Pollinator syndromes aren’t always correct but are used as a starting place to predict interactions. Apparently, only one-third of plants can be accurately classified according to pollinator syndromes.

Here is an example.

Great Spangled Fritillary on Purple Coneflower

Butterflies tend to visit flat blossoms with many nectar sources or small flowers. The flatness of the blossom provides a nice stable landing pad. Butterflies like asters, sedums, milkweeds and coneflowers for those reasons.

False Indigo (Baptisia australis)

Bees like blossoms that give plenty of nectar and lure the bees in with a sweet fragrance. They tend to visit flowers white or blue. Hummingbirds tend to visit red, tubular shaped flowers.

Use the chart below to  help explain why certain plants attract bees, butterflies or other animals.

A Magnificent Magnolia

Magnolia virginiana L. 'Sweet Bay Magnolia

Sweetbay Magnolia has began to bloom early this spring. In the dark shade of a woods, the tall shrub glows with the soft white creaminess of large blossoms that seemly float in mid-air.

I went to Temple University’s Ambler campus arboretum especially to see who was blooming. The Magnolia virginiana L., along the walkway, was just beginning to flower. And and it’s sweet, fruity scent filled the late afternoon air. It is commonly called, ‘Sweetbay’.

I had to put my nose  deep in a blossom and breathed in. After a winter of bare trees and chilly temperatures, this heady first scent of spring was intoxicating.

Sweetbay is the most heavily scented of the magnolias. The fragrant flowers attract beetles and perhaps moths. The flowers scent is strongest in the afternoon, all the better to attract dusk-flying moths.

The bowl-shaped flowers are classic “beetle flowers”,with their large solitary flowers which are dull white to green, strongly fragrant and open during the day.

The flowers open a few at a time over a span of a month or more. So, we get to enjoy its ephemeral beauty from late spring into June.

Sweetbay is easily my favorite magnolia. Most often you hear of southern magnolias, but magnolias grow naturally around the Philadelphia area.

This multi-stemmed slender shrub is native to Philadelphia. New York and Connecticut are the northernmost part of the range. Depending on the climate, this magnolia can be evergreen, partial evergreen or deciduous.

Sweetbay is a rare and threatened plant here in southeastern Pennsylvania. It is a treat to find it growing in the sandy wetlands of the Atlantic Coastal Plain and drier upland forests of the Piedmont.

The Sweetbay Magnolia grows beneath the canopy of the oaks, hickories and Tulip tree of the local forests.

Except for the Cucumber Tree (Magnolia acuminata) all the native magnolias are understory trees. This makes magnolia a small tree good for planting in gardens.

'Sweet Bay', get lost in the sweetness

Sweetbay has perfect flowers, meaning the blossom contains both male and female parts. The flowers bloom before the leaves open. After the flowers are fertilized, the seeds develop and are dispersed by mammals, birds, heavy rains and/or gusty winds.

Magnolia x soulangiana, 'Saucer magnolia'

Magnolia x soulangiana, 'Saucer magnolia', a non-native

I watched the showy Saucer Magnolia bloom early and end early. It’s blooms were finished as the Sweetbay began. Saucer Magnolia is not a North American native but an import from Asia. It blooms before many North American magnolias. Saucer Magnolia blooms so early, the flowers can be killed by frosts.

I have taken some gorgeous close-up shots of  it’s blossoms. The large pink and white blooms of Saucer Magnolia look somewhat artificial, like cheap plastic flowers you would find in a dollar store.

I look forward to the blooming of the magnolias. The elegance of Sweetbay is reminiscent of a well-dressed lady. Tasteful and refined but with a beauty the draws you to stop and rudely stare at someone so lovely.
