#90YearsofMorris: Opening Day, 1933 Ninety years ago today, the gates of the Morris, the estate formerly known as Compton, swung open to the public for the first time. That week in June 1933, eighteen months after Lydia Morris's death, marked the transition from private estate to public garden amidst great fanfare and publicity. Ninety years ago today, the gates of the Morris, the estate formerly known as Compton, swung open to the public for the first time. That week in June 1933, eighteen months after Lydia Morris's death, marked the transition from private estate to public garden amidst great fanfare and publicity. The Philadelphia Bulletin  reported that 10,000 visitors enjoyed the Morris on that first day. The Philadelphia Record  heralded the news with a large photo and the front-page headline, "Morris Arboretum Goes to Posterity." Image Maurice Bower Saul, '05L .,'07C.

The Philadelphia Ledger reported, "The Arboretum's gardens are said to rival the Arnold Gardens in Boston, the Kew Gardens of London or the Jardin d'Acclimation of Paris," and The New York Times  described the opening as "An El Dorado of horticultural treasure." Once the Morris became part of the University of Pennsylvania, the focus shifted from that of an aesthetic landscape garden …

Garden Railway: Chugging Along Since 1998 The Garden Railway is celebrating 25 years with a new addition—300 feet of track! The Garden Railway is celebrating 25 years at the Morris Arboretum & Gardens with a new addition—300 feet of track! This is the largest expansion of the Garden Railway since it was installed in 1998. The new looping section of track extends the total model rail trackage to a third of a mile, making it one of the largest outdoor model train displays in the country.  Image The extension of the Garden Railway in progress.

Giving Thanks to the Great Oak of North Coventry Township Morris Arboretum & Gardens’ Urban Forestry Consultants recently visited North Coventry Township in Chester County to inspect a white oak ( Quercus alba ) known locally as the “Great Oak.” The tree’s owner and the arborist caring for it became concerned about the biological health when many branches on half of the tree failed to leaf out this spring. Morris Arboretum & Gardens’ Urban Forestry Consultants recently visited North Coventry Township in Chester County to inspect a white oak ( Quercus alba ) known locally as the “Great Oak.” The tree’s owner and the arborist caring for it became concerned about the biological health when many branches on half of the tree failed to leaf out this spring. Considered a “William Penn Tree,” the Great Oak is one of 100 or so living trees in the region that were alive around the time William Penn landed in Pennsylvania in 1682. While the tree’s exact age is unknown, estimates range from 400–600 years old, well before Penn’s landing. We arrived on the scene to assess why this ancient tree was declining after all these centuries. We started by measuring the tree. Although not exceptionally tall at 60 feet, the Great Oak has a 76-inch diameter and a massive canopy spread of about 115 feet. From there we inspected the entire tree from branches to trunk flare. There was deadwood, branch wounds, and old pruning wounds all over the tree, which showed its resilience through the centuries. About half of the canopy was either dead or struggling to put out leaves. Around the Great Oak’s base, we found that the trunk had been buried quite a bit by mulch or dirt over time. Tree trunks are adapted to grow above ground, and burying the trunk creates moist conditions that invite fungi and other organisms to attack and decay the now buried trunk. We found the bark on the buried buttress roots was decayed, which was compromising the connection between the roots and canopy, along with the …

Plant Names and Provenance: Fothergilla spp. Fothergilla spp . are in the witchhazel family, and attract pollinators with the showy stamens of its male flowers. Named for Dr. John Fothergill (1712–1780), an English physician with a thriving medical practice, the Morris hosts a range of these plants including fothergillia ʻMt. Airy’ ( F . × intermedia ʻMt. Airy’). Image 1993-153-A Fothergilla × intermedia ʻMt. Airyʻ. Spikes of flowers lack petals but attract insects with scent and prominent  stamens composed of  creamy white filaments tipped with yellow anthers. Photo by Clara Roth,  McClean Contributionship Youth & Visitor Education Intern. Fothergilla spp. are in the witchhazel family, with leaves and fruits similar to those of Hamamelis (witchhazel), but quite different flowers: Hamamelis has colorful petals, while the apetalous (having no petals) fothergilla attracts pollinators with the showy stamens of its male flowers. Fothergilla is named for Dr. John Fothergill (1712–1780), an English physician with a thriving medical practice subsequent to his fame for writing a book carefully describing serious forms of sore throats, or what we now call diphtheria and scarlet fever. In fact, Fothergill had a strong friendship with Benjamin Franklin, whom he treated when he fell ill on a trip to London as well as supported Franklin’s work in establishing Pennsylvania Hospital by sending seven cases of anatomic drawings and three plaster casts of pregnant women to be used as teaching aids. (These casts can be seen on pre-arranged, guided tours of the historic Pine Building on the Hospital campus.)
