At the Frelinghuysen – August 16, 2023

Several weeks ago, we featured the lovely Koelreuteria paniculata ‘Rose Lantern’ tree. The delicate yellow flowers have transformed into green “lanterns”; eventually these will dry and hold the next generation’s seeds. Isn’t nature amazing?

At the Arboretum 8/8/23

A pretty Crapemyrtle (Lagerstroemia cv. ‘Acoma’) is blooming along the driveway as you come up from Hanover Avenue, its delicate, crinkly, white flowers floating above the foliage like soft little clouds. The attractive, exfoliating bark offers winter interest once the foliage and flowers have fallen.

A Sampling of Plants from Portugal

Regardless of where my travels may take me, I am always drawn to the plants and flowers typical of the area I’m visiting. A few special ones from my recent trip to Portugal:

High above the Atlantic Ocean at Cabo da Roca (the westernmost point in Europe) I found a feathery yellow flower blooming among its succulent-like leaves, probably a Delosperma (Ice Plant).

In a seaside town, lining the street, the striking red bottlebrush flowers of the Pohutukawa metrosideros excelsa trees (New Zealand Christmas Tree) were putting on quite a show.

Bougainvillea could be found everywhere, draped over walls, fences and buildings and covered in masses of papery magenta flower bracts.

A day trip to the Douro Valley was a wonderful experience; the hillsides of this World Heritage designated area are covered in grapevines as far as the eye can see. The harvest will begin in September followed by the production of the world famous Port wines of Portugal.

Sunday Saunter – 7/30/23

Thanks to frequent contributor, Steve Kanan, for another batch of lovely pictures. He said he enjoyed normal weather so much that he followed up his morning visit with another in the afternoon.

Don’t miss out on summer at the Frelinghuysen — visit the gardens soon.

Photo Highlights from Katharine Boyle

Katharine Boyle visited the Arboretum yesterday and sent this batch of beautiful pictures along with the following note:

…it’s been a while. And to my utter surprise, I spotted a pineapple there! It must have been “welcoming” me back.

Thanks, Katharine, for the lovely images.

Hibiscus Flowers at the Arboretum

There are many varieties of Hibiscus plants; two that are currently in bloom at the Arboretum are Hibiscus moscheutus and Hibiscus syriacus.

Hibiscus moscheutus (Swamp Rose Mallow) is a herbaceous perennial that produces dinner plate sized flowers. The plants can reach 3-7 feet tall by 2-4 feet wide. New growth is slow to emerge in spring, but grows quickly thereafter. Hibiscus moscheutus cv. Kopper King is a pretty shade of pink with a dark pink throat. A bright red Hibiscus moscheutus (possibly ‘Lord Baltimore’) is blooming nearby.

Hibiscus syriacus (Rose of Sharon) is a close relative of H. moscheutus. A native of eastern Asia, it is a vigorous, upright, vase-shaped, multi-stemmed, deciduous shrub which grows to 8-12 feet tall. Currently in bloom at the Arboretum are a white flowered plant, Hibiscus syriacus cv. Diana and the blue flowered H. syriacus ‘Blue Bird’.

Several other varieties are also in bloom, why not visit and check them out for yourself?

HOT FLOWERS IN THE ARBORETUM’S GARDENS

Shades of red, orange and yellow are considered “hot” colors; in the garden, they serve to brighten up a spot, highlight an area and/or provide a focal point to lure you in for a closer look.

The arbor at The Frelinghuysen Arboretum holds a large Trumpet Vine (Campsis radicans), covered at this time of the year with big orange flowers. The Trumpet Vine is a vigorous, deciduous woody vine growing to about 33 feet long, with shiny, dark green, pinnately compound leaves. The flowers are each about 3.5 inches long, trumpet shaped and lacking in scent. After flowering, a six inch long seed capsule forms, dries and splits releasing hundreds of thin, brown, paper-like seeds. It is native to the Eastern United States..

Another name for the plant is Hummingbird Vine because the flowers attract these tiny, jewel-like summer visitors. The vine also attracts a variety of other creatures: Birds nest in the vine and moths, bees, flies and ants feed on the nectar.

A variety of vegetables and fruits are grown in the Barkman Vegetable Garden and this year there is a large bed of Sunflowers (Helianthus) growing against the fence, providing a nice, bright sunny yellow show. Sunflowers are native to the Americas and are said to symbolize long life and lasting happiness.

An interesting fact about Sunflowers is that they track the sun (heliotropism). At night, Sunflowers face east, anticipating the sun’s return and track its progress throughout the day. They do this until they get old and stop moving.

The gardens at The Frelinghuysen Arboretum hold a large variety of hot blooming plants, visit soon and discover them for yourself!

THE BLUE GARDEN AT THE ARBORETUM

Blue in the garden can create a cooling, soothing, restful atmosphere. This can be achieved by using flowers, foliage, garden ornaments, etc., in all shades and hues of blue. The Blue Garden in front of Matilda’s Cottage contains all sorts of blue flowered plants, from annuals such as Fan Flower (Scaevola) to perennials such as Balloon Flower (Platycodon grandiflorus) and the airy, delicate flowers of Love-in-a-Mist (Nigella damascena). Blue metal benches and a tall blue tuteur providing a climbing structure for a Clematis vine, complete this garden.

Visit this lovely garden room soon, sit on one of the blue benches and watch the bees and butterflies as they hover around the many flowers in the garden.

At the Arboretum July 5, 2023

Today we’re featuring the lovely Koelreuteria paniculata ‘Rose Lantern’. This is a dense, rounded, deciduous tree which grows to a height of between 30 and 40 feet with an equal or greater spread. It has pinnate leaves that emerge reddish in the spring, mature to a bright green and turn yellow in the fall. Airy panicles of delicate golden yellow flowers bloom in summer followed by dramatic, rose-pink, bladder-like fruits in the fall.

Known as the Golden Rain Tree, the Arboretum’s specimen can be seen on the left at the end of the first parking bay as you come up the driveway from Hanover Avenue. Make a point of visiting it soon and come back to see the bladder-like fruits in the fall!

At the Arboretum – June 28, 2023

Here are just a few of the unusual plants used in this year’s entrance gardens to the Haggerty Education Center. Plantings made possible by a grant from the Friends of The Frelinghuysen Arboretum. 

Talinum paniculatum ‘Jewels of Opar’: A succulent subshrub commonly known as Fame Flower or Pink Baby’s Breath. The bright lime green leaves and small pink flowers held atop thin dark stems are a lovely addition to the garden bed. The plant is native to much of North and South America and the Caribbean.

Mangave ‘Silver Fox’: A hybrid plant that offers the attractive structure of Agave and the faster growth and colors of Manfreda. It has broad, toothed blades with a thick waxy coating and can tolerate more water than other succulents.

Berkheya purpurea ‘Zulu Warrior’: A deep rooted and drought tolerant South African native perennial. It has single, smoky lavender flowers with dark purple centers held atop flower stalks that can reach 3 feet in height. The plant has spiky silvery green leaves and makes an excellent cut flower.

Ptilotus exaltatus ‘Joey’: A compact, short-lived herbaceous perennial with large, long lasting, conical spikes of feathery flowers. Attracts bees and butterflies and is a good cut flower.
