Elegy for the Lebanon Cedar For the last several decades, our majestic cedar of Lebanon trees ( Cedrus libani ) have struggled to survive our changing weather. In 1887, when John and Lydia started their Compton Estate, Lebanon cedar was considered a well-adapted plant for the Philadelphia region and was often planted as a featured specimen. We have had several Lebanon cedars in our collection, but only two remain from the original garden. Image Cedar of Lebanon ( Cedrus libani ) that was once located in between Exuberant Blooms and the Springhouse in the Azalea Meadow. For the last several decades, our majestic cedar of Lebanon trees ( Cedrus libani ) have struggled to survive our changing weather. This evergreen conifer is native to  the  mountainous regions of Lebanon, Syria, and Turkey. Young trees grow as strong, upright sentinels. As they age, they develop massive trunks, broad spreading crowns, and distinctive horizontal branching, making them magnificent specimens for parks and arboreta. In 1887, when John and Lydia started their Compton Estate, Lebanon cedar was considered a well-adapted plant for the Philadelphia region and was often planted as a featured specimen. We have had several Lebanon cedars in our collection, but only two remain from the original garden. Lebanon cedars, like many higher elevation conifers, have evolved a survival strategy of markedly slowing their growth and respiration rates during cool nights. This ability allows them to make maximum use of warm daylight temperatures to produce sugars and essentially go dormant during cool nights to conserve energy. This mechanism allows the trees to build up a surplus of stored energy over time. This energy, in the form of sugars, is then used to produce vigorous growth in what would normally be inhospitable environments. This strategy works in a high elevation environment where there are reliable cold nights, but it also predisposes this species to heat stress. When nighttime temperatures are …

Liddon Pennock Jr. Horticulture Apprentice Image “I like the Springhouse because it’s a piece of Morris history that makes me imagine what it would have been like to live on the estate.

It’s maintained as a natural landscape, and is a fantastic place to see and hear all sorts of wildlife. As a birder, I love checking in to see which birds are stopping by for  the season—it’s where I saw my first indigo bunting last summer. Don't miss out on this Morris gem!” – Megan Nguyen, Education Administrative Assistant Image “My hidden gem is the weeping European beech (Fagus sylvatica f. pendula) across the way from Two Lines sculpture. In the middle of the weeping branches is a dead log that seems out of place at first glance, but it's actually the decaying remains of the original tree. The trees that are around are the rooted layers of the original mother tree. [Despite appearing as separate trunks, all these trees are individual parts of a single organism, sharing a network of interconnected roots underground.] Sitting here …
