I didn’t let summer’s final gasp of heat and humidity deter me from a walk in the Arboretum on Wednesday, although, after a month-long break in 90-degree heat, I felt like I was experiencing the first hot day of the season. I spotted a nursery web spider (Pisaurina mira) biding its time under a leaf. Note how it rests with its two front legs touching each other.
This spider has a dark stripe running down the middle that is bordered by a white margin, which undulates along its abdomen. Also note the white hairs along its body and the black spines on its legs.
Can Southern magnolia trees survive in Boston? I thought not. Even the Arboretum’s own Bulletin of Popular Information, didn’t think so, saying in May of 1911 that Magnolia grandiflora is “not hardy at the north.” That changed in 1983, when a tree was planted behind the Visitor Center. More accessible, however, is a tree just off Meadow Road behind a red maple. Planted in 1998, this cultivar — Bracken’s Brown Beauty — is doing very well.
I took photos of a wealth of natural life at the Arnold Arboretum yesterday. Among the birds, dragonflies, frogs, and plants, only one of the subjects was accessioned: Wilson’s spiraea (Spiraea wilsonii).
