Summer is hydrangea season!  These beautiful flowering shrubs are dotted throughout the Winterthur Garden providing oases of summer color.  The blooms range in shades of white, pink, purple, and blue and vary in shape; mopheads, lacecaps, and panicles.  The leaves are also widely variable as is the overall size and habit of each hydrangea.  All of these attributes are dependent on the species and cultivar of each plant.  There are eight different species of hydrangea in the Winterthur garden, including, Hydrangea anomala subsp. petiolaris (Climbing Hydrangea), Hydrangea arborescens (Smooth Hydrangea), Hydrangea aspera subsp. sargentiana (Sargent Hydrangea), Hydrangea involucrata (Bracted Hydrangea), Hydrangea macrophylla (Big Leaf Hydrangea), Hydrangea paniculata (Panicled Hydrangea), Hydrangea quercifolia (Oakleaf Hydrangea), and Hydrangea serrata (Mountain Hydrangea).  Additionally, there are numerous cultivars among the species.  The extensive number of different hydrangeas often leads to questions of identification.  An accurate label is the best way to gain this information, especially in reference to the cultivars, however, good observation can help identify the species and often times the cultivar.

The type of bloom varies with the species.  In general, hydrangea blooms are either mopheads (also referred to as hortensias), lacecaps, or panicles.  Both mophead and lacecap hydrangeas produce corymbs; flower clusters where the flower stalks are of different lengths creating a ball-shaped or flat-topped bloom.   Mophead hydrangeas produce large rounded flower heads, which consists mostly of showy infertile (sterile) flowers (the “petals” are actually sepals).  Lacecap hydrangeas produce flattened flowers, which consists of showy infertile flowers (again these “petals are actually sepals) radiating around a central cluster of tiny fertile flowers.  Some hydrangeas produce panicles, which are long and tapered and typically have a mix of showy infertile flowers and tiny fertile flowers.

Panicle

In the Winterthur Garden, the hydrangeas with mopheads include Hydrangea arborescens, Hydrangea macrophylla, and Hydrangea serrata; the hydrangeas with lacecaps include Hydrangea anomala subsp. petiolaris, Hydrangea arborescens, Hydrangea aspera subsp. sargentiana, Hydrangea involucrata, Hydrangea macrophylla, and Hydrangea serrata; the hydrangeas with panicles include Hydrangea paniculata and Hydrangea quercifolia.  Growing the different species provides the garden with blooms from June through September and spans the breadth of the garden from the Summer Shrub Area along the front drive (near the Flag Pole) all the way to Sycamore Hill.  The largest plantings can be found in the Summer Shrub Area, near Clenny Run (in proximity to the Museum Store), the Glade, Magnolia Bend, Enchanted Woods, and Sycamore Hill garden areas.

Throughout the bloom, each species will be highlighted individually in upcoming blogs, which will include further information on identification, growing requirements, and pruning tips.

Added this quick video of the hike…

 

This week I chose another trail that takes you in and out of shaded woodland, with an opportunity to see one of our most striking meadows and an absolutely huge tulip poplar. Once again, I linked two trails – Armor Farm and Chandler Woods – to create a large, irregular figure-8 loop that is 2.6 miles long. I have outlined my walk below and provided a photo gallery (by the way, if you would like a PDF version of our hiking map follow this link www.winterthur.org/map). For those tech-savvy walkers I am providing a link to an AllTrails map below that allows you to follow the route with your smartphone. Happy hiking!

Introduction Panel for White Arrow Tour

Winterthur is welcoming guests back into the garden once again on July 1st. Our beautifully choreographed spring display has transitioned to shaded paths, trickling water features and punctuations of summer color. Some of the highlights in the garden right now are hydrangeas, summer perennials such as daylily and Actaea (bugbane) with the purple flowers of Hosta ventricosa filling the woodland landscape within the upcoming week. Wildflowers and wildlife are burgeoning along many of our meadow paths and the woodlands are filled with the sounds of birdsong. Mostly what we can offer is a little respite from the world.

If you are unfamiliar with way-finding in the garden, the “white arrow tour”, usually reserved for highlighting the spring flowering progression, is up and will guide guests throughout the garden, getting a taste of each garden area and featuring some of the best vistas on the property. The tour begins and ends at the same location at the far end of the Visitors Parking Lot near the Picnic House. At a leisurely pace, it takes about 45 minutes but you will likely want to sit and take in some of the views along he way. The loop, end to end, (without meandering distractions) is about 1.5 miles.

For more information on tickets and protocol, please visit our website https://www.winterthur.org/ . We welcome you back to the garden and hope that you find serenity among the many beautiful nooks and wide-open spaces.

Nursery Woods Trail 

As many of you have discovered, Winterthur has several miles of walking trails worth exploring. With close to 1,000 acres available for guests and members to walk, there is so much to discover, photograph, and enjoy on the estate. I recently chose to hike two of our trails, linking them together to create a 2.6 mile walk. I started at the Visitors Parking Lot and walked to the beginning of the Nursery Woods trail. I followed that to our Point to Point course and then followed Old Gatehouse Road to the Sawmill Woods trail and used that to walk back into the core of the property. I have outlined my walk below and provided a photo gallery (by the way, if you would like a PDF version of our hiking map follow this link www.winterthur.org/map). I have also made a short video of the walk and provided a link – for those tech-savvy walkers – to an AllTrails map that would allow you to follow along with your smartphone. Happy hiking!

More Rhododendrons!

Rhododendrons continue to color the Winterthur Garden in white, pinks and lavenders. Rosebay Rhododendron, (R. maximum) is a large broadleaf rhododendron native to eastern North America. Its flowers are just now opening and you can find them near the lower Peony Garden, the Visitor Center’s entrance and the March Bank. They traditionally flower in either white or a soft pink.

 

 

 

 

 

 

 

 

 

 

 

 

‘Mr. Bluestem’ is a cultivar that was selected and named by Rarefind Nursery. Its rosy flowers open slightly earlier than our maximum.  We have a few young plants in flower on the west side of the museum.

Rhododendron ‘Mr. Bluestem’

 

R. maximum generally flowers later than our other native broadleaf rhododendron, R. catawbiense but their flowering times can overlap depending on location so hybrids with intermediate flowering times are available.  You will find a corridor of these at the Vista Ending Arch. One of our native hydrangeas, H. arborescens ‘Grandiflora’ is the first to come into flower and brightens that rhododendron path.

H. arborescens ‘Grandiflora’

Rhododendron hybrid

 

 

 

 

 

 

 

 

 

 

Martagon hybrid lilies are another excellent addition to the early summer shade garden. These lilies can take dappled shade to full sun. Their key characteristics include whorled leaves, small downward facing flowers and recurved petals. From our plant records, we know they were in the Winterthur garden by at least the 1960s and continue to thrive in Azalea Woods and Enchanted Woods.

 

 

 

 

 

 

 

 

 

 

 

 

 

Recent additions to expand the collection and color palette include ‘Claude Strine’ and tsingtauense.  Plan your visit for early this week to catch these in flower.

b: Some bloom
fb: Full Bloom
pf: Petals falling/drying
pb: Past bloom (few remain)
ber: Berries, fruits
.
Check these out:
 Don’t miss the lilies (Lilium martagon) that are in full bloom in Azalea Woods and Icewell Terrace. Their show doesn’t last very long.
 Enjoy the lovely drifts of white foxglove beardtongue (Penstemon digitalis) that can be seen in the meadow below Brown’s Woods while walking along Garden Lane past the Pinetum.
 The candelabra primroses (Primula japonica) in the Quarry Garden are still colorful.
 Sycamore Hill has great displays of mountain laurel, roses, red weigelia, deutzia, and leptodermis.

 Found throughout the gardens but mentioned only here:
o Look up to see the remaining green & orange tulip tree (Liriodendron tulipifera) flowers – or down on the paths to see flowers or pieces of flowers throughout the gardens.
o The tiny white, sometimes pale pink, daisies of fleabane (Erigeron annuus) are scattered throughout the meadows & gardens.
o White clover (Trifolium repens) in the fields and lawns is providing nectar and pollen for the pollinators and nitrogen for the soil.

Bloom Report Presented by:
Pauline Myers

It has been wonderful to see our members back, once again, walking the garden. Each day we learn a little more about how best to provide access while managing the needs for physical distancing and hygiene. We thank you for your patience!

Some of you have discovered our recently published trail map, that provides an overview of the entire estate. For a letter-sized version follow this link (TrailMap060120208x11) or visit www.winterthur.org/map.

Here are some tips for “walking Winterthur.”

For those of you who have visited, you realize there are some restrictions and that most of our buildings are closed, but that we are doing our best to make it safe and comfortable for walking and taking in the scenery.

Reservations
In order to walk at Winterthur our members need to make reservations for one of five time slots available each day. Through this process we can manage the numbers of guests on site. We will announce any updates to this process through member e-blasts.

Restrooms
Currently, the Picnic House restrooms, 1750 House restroom, and Reflecting Pool restrooms are open. We will keep you updated if there are changes! Water bottle fillers are active at the 1750 House, Quarry restrooms, and Reflecting Pool restrooms.

Maps
This is the fun part! Our mapping specialist and our Natural Lands team have been hard at work drafting a trail map (pictured above). We have posted this near the Picnic House and have also made it available online. Our garden map can also be found at the link www.winterthur.org/map and there are paper copies of the garden map available in the Picnic House. In addition, our Mapping Specialist has updated Google Maps to give an accurate representation of the roads and facilities throughout the estate if you want to use your phone to navigate with a live ‘you-are-here’ symbol. She is exploring the options of having a live, clickable, map available for your smartphone and of including our map information in the popular AllTrails app. More to come…

Rhododendrons continue to brighten and perfume the Winterthur garden. We don’t know the stories behind all the cultivars but one is particularly telling in respect for Mr. du Pont’s prestige in the horticulture field.  Joseph Gable, one of the pioneering azalea and rhododendron hybridizers of the early twentieth century wrote the following to H.F. du Pont in June 1955.

“The plant of Rhododendron “Gable’s Pink #2” – (until it is introduced and I find a better name for it) was settled for by Mrs. Dean and Mrs. Ross when they were here and is their gift to you though it is a plant not yet released to the trade and I made something of a special dispensation in allowing them to have it for you.”

Rhododendron ‘Robert Allison’

Mr. Gable did find a better name for it and called it Rhododendron ‘Robert Allison’. It has lovely, fragrant pink flowers in bloom now on a tall plant, easily reaching 10’.  Its sister seedling is named ‘Cadis’ and also offers fragrant pink flowers in early June.

Rhododendron ‘Cadis’

You can find additional early June flowering broadleaf rhododendrons by other breeders in Azalea Woods and near the museum store. Colors will vary from lavenders, pinks, red and white.  Another wonderful way to extend the season of color in the garden.

Rhododendron hybrid soft mauve is just opening this week and also offers good evergreen foliage which covers the entire plant.  You will find it at the entrance to the Visitor Center and above the Museum Store on Clenny Run.

We received ‘Lady Eleanor Cathcart in 1955.  It tends to be more open but the space below can be used to grow shade loving perennials such as ferns.

‘Mrs. Charles S. Sargent’ was probably in the garden at least by the mid-1960s and is one of our shorter broadleaf rhododendrons. It can be found in Azalea Woods.

Rhododendron ‘Chionoides’

Rhododendron ‘Chionoides’  arrived in 1965 and is now one of our largest and widest rhododendrons. Discover it in Azalea Woods just past ‘Lady Eleanor  Cathcart’.  Rhododendron discolor and Rhododendron maximum will soon join the show and extend the color through the month of June.
