Hydrangea Paniculata

Native to China and Japan, this tough, deciduous shrub grows to a height of 15 feet and a width of 8 feet or more and looks spectacular when grown in mass plantings and hedges.

New York City can get cold

Of all the hydrangea varieties growing in Theodore Roosevelt Park, Hydrangea paniculata is best able to tolerate low temperatures. Although most hydrangeas prefer partial shade, the hydrangea paniculata tolerates full sun in northern growing areas.  This shrub prefers loamy, well-drained soil.

Blossoms on 81st street

Hydrangea paniculata flowers will bloom all summer long.  They form pyramid-shaped clusters, 6 to 8 inches long, of creamy-white blossoms that turn pinkish-purple at maturity.

Panicle hydrangeas grow in several gardens along the northern end of Roosevelt Park, at 81st Street between Central Park West  and Columbus Avenue.

What determines the color of hydrangea flowers?

Hydrangea grow in many of the gardens in Theodore Roosevelt Park. Their colors range from indigo blue to purple to bright pink. Hydrangea macrophylla, a plant that is native to China and Japan, produces different colored flowers depending on the soil pH.

Acidic or alkaline soil

 When the soil is acidic, meaning the pH is below 7, Hydrangea macrophylla produces flowers that are closer to blue. Hydrangea growing in alkaline soil (pH above 7) produce flowers in the pink and lilac color range.

Long-blooming flowers

Hydrangea Macrophylla will bloom until late autumn, and they can grow six feet tall. These plants can do well in full sun or partial shade. Look for these beautiful flowers in our gardens at the 81st Street side of the park, near Central Park West and Columbus Avenue, and in front of the Hayden Planetarium and the Bull Moose dog run.

It’s never too soon to plan for fall!

While our visitors are luxuriating in the summer warmth and enjoying the current blooms, gardeners must plan ahead. The Friends of Roosevelt Park have purchased 3,500 flowering plant bulbs for our fall planting.

What are the most colorful flowers on the Upper West Side?

Expect four weeks of color with the addition of Spanish Blue belles; white bell-shaped snowflakes; white winged snowdrops; yellow, white and golden yellow daffodils; red, yellow and purple tulips, and lilac-pink alliums.

Sigma Delta Tau volunteers help us create a new garden

On June 24th, 2017, Theodore Roosevelt Park held one of its largest volunteer events of the year. More than 100 volunteers from Sigma Delta Tau, a national sorority, visited the Upper West Side to join Partnership for Parks personnel, GreenLife Interns, and NYC Parks & Recreation gardening staff in cleaning, weeding, and creating a new flower garden at Columbus Avenue and 81st Street.

Hundreds of new flowering plants

The Sigma Delta Tau volunteers donated hundreds of new plants, including heuchera, hosta, hellebore, hydrangea, mahonia, anemone, and Japanese forest grass. Volunteers also weeded extensively throughout the park. In addition to being one of the largest volunteer events this year, it was one of the most productive.

What is Sigma Delta Tau?

Sigma Delta Tau is a national sorority with more than 60,000 members. They are committed to empowering women, and as observed last week, dedicated to beautifying parks.

AzaleasAzalea (Rhododendron sp.) flower blossoms are lighting up Theodore Roosevelt Park with brilliant hues of pinks and reds.

AzaleasThe colors of late spring

Flowering in late spring, and after tulips, daffodils and cherry blossoms have faded, azaleas brighten Roosevelt Park with splashes of dazzling color that last for weeks.

The showy, funnel-shaped flowers can be seen growing under dappled shade along Columbus Avenue and 79th Street, and in front of the Planetarium.

Around the world and the Upper West Side

Azalea shrubs are hardy, shade-loving perennials, native to North America, China and Japan that grow well in acidic, moist soil with good drainage – growing conditions available throughout our park.

Spring Sun Brings Tulip Blooms

The tulip (Tulipa) is an upright herbaceous perennial bulbous plant in the lily family, growing from 4 to 24 inches in height.  Native to Central Asia and cultivated in Holland, tulips are one of the most beloved and recognizable flowers in the world.

Flowering from early April to May, tulips have no rivals for providing springtime carpets of pure, intense, vibrant color.  Gorgeous blooms, usually one flower per stem, are available in almost any color except blue and black.

Tulip gardening in the park

Tulips in Roosevelt Park

Garden near E 81 St. and Central Park West

It’s difficult to get tulips to produce blooms year after year. At Roosevelt Park, we maximize tulip flower bloom by choosing sites with well-drained soil in full sun, we plant bulbs deep, (8”) in late fall, water-in bulbs after planting, and purchase bulbs that naturalize well (Darwin hybrids and species tulips).

Tulips will tolerate light shade, but the flower bloom will not be as spectacular, nor will the flowers bloom as well the following spring.  Tulips grow poorly in heavy shade.

Full sun allows the greatest amount of carbohydrates to translocate in the flower bulb, providing necessary nutrients for flower bloom the following spring.  Leaves should be allowed to remain on the stems until turning yellow (about 8 weeks).

NYC is good for tulips!

Tulips in Roosevelt Park

Garden in front of Hayden Planetarium flagpoles.

Tulips require a chilling period of 12 to 16 weeks at soil temperatures around 40 degrees F. and therefore do not grow well in warm climates.  Tulips thrive in New York City weather.

How long should tulips last?

The majority of tulip bulbs in Roosevelt Park were planted last fall. With the right growing conditions, tulips can bloom for three or more seasons, so we expect our current tulips to bloom at least until 2019.

Cherry tree

Have you seen the flowering cherry trees, now in spectacular full bloom in Theodore Roosevelt Park?  An absolutely jaw-dropping display of marvelously formed, delicate pink blossoms, cascading over bent branches.   Pink petals float through the air, carpeting the walkways.

Beautiful blossoms are well-suited to New York City

Cherry BlossomFlowering cherry trees grow well at Theodore Roosevelt Park and have few rivals for sheer beauty.  Cherry trees need full sun and well-drained soil for optimum health, and their location in Roosevelt Park provides these conditions. Flowering cherry trees are grown throughout New York City, including in Central Park, Brooklyn Botanic Garden, and New York Botanical Garden.

New York Cares volunteers

On Saturday, April 22nd, 70 volunteer gardeners and 7 Greenlife interns joined New York Cares team leaders and New York City Parks Department staff to lend their passion and horticulture skills to clean up and plant flowers in Theodore Roosevelt Park. As volunteers assembled in front of the Hayden Planetarium, one woman said that she and her group of 15 high school students had traveled 4,000 miles, from Denmark, to volunteer at the park during their New York City visit! Volunteers worked steadily for three hours, in spite of the chilly, intermittent rain.

Spring cleaning and planting

Planting flowersThe gardens in front of the Bull Moose Dog Run were cleaned of dried leaves and weeded, and the pathways were swept clean.  Volunteers planted redosier dogwood (Cornus sericea), lavender (lavandula grosso,) and blazing star (liatris spicata).  These shrubs and perennials will provide desirable color, texture and form to our favorite Upper West Side park.

Lavandula grosso (lavender)

Lavender is a French hybrid with gray-green foliage. It grows into a shrubby mound 30 inches tall, and produces abundant fragrant, dark blue flower spikes in mid-summer.

Greenlife Interns

Cornus sericea (redosier dogwood)

Redosier dogwood is an upright, spreading shrub that can grow up to 10 feet tall. Small white fragrant flowers bloom in late spring, and fruit is produced the following summer, attracting birds. In the winter, stems turn bright red, an attractive contrast to a snowy background.

Liatris spicata (blazing star)

Blazing star is a clump-forming perennial, growing to 2 – 4 feet tall. It forms terminal spikes of purple flower heads in the summer.

The benefits of volunteering

Volunteers in Roosevelt ParkJudging from their smiles and friendly conversations, all of the volunteers enjoyed their work, admired their horticultural accomplishments, and felt proud to be able to contribute to the beautification of Theodore Roosevelt Park. Stop by the park in a few weeks to see how the flowers are coming along!

Earth Day

Roosevelt Park Trees and Flowers

The first Earth Day was celebrated on April 22, 1970. Conceived by Wisconsin Senator Gaylord Nelson, Earth Day was intended to increase awareness of threats to the environment.

Roosevelt Park NYC bare dirtTwenty years after the first Earth Day, The Friends of Roosevelt Park were a newly formed group, dedicated to the restoration of Roosevelt Park. The park had been neglected, resulting in stretches of bare dirt broken interspersed with dead plants. It was a stressed environment.

Today, Earth Day has become an international observance, and Roosevelt Park has been restored to a welcoming slice of nature in the city. Its 10 acres are filled with trees, grass, and flowers. This Earth Day, come sit on one of our benches and celebrate how far the park has come!
