Visitacion Valley Tree Tour (1-22-22)

 

 

We’ve noted before the inequity in street tree plantings within San Francisco. Today’s walk took us to Visitacion Valley near the city’s southern edge. Once known for its many greenhouses and family-run truck farming operations, this working class neighborhood of modest homes offers little in the way of amenities such as street trees. It does, however, offer the Visitacion Valley Greenway (VVG), which runs through several blocks and is filled with delightful green open spaces, colorful gardens, children’s play areas, and a surprising array of trees. The Greenway is a key part of the 17-Mile Crosstown Trail, which runs from the southeastern corner of the city to Lands End in the northwest corner of the city.  

Today’s walk begins at the entrance to the Hans Schiller Plaza of the Visitacion Valley Greenway, just to the left (west) of 144 Leland Avenue, the site of Mission Blue Cafe—a coffee-lover’s highlight of “downtown” Visitacion Valley. The walk immediately crosses Leland to the south for a couple trees just west of Peabody Street, then loops back to Peabody for a few trees just south of Leland, including two in the parking lot behind 141 Leland. Returning to Leland, the walk heads west one block to Rutland Avenue and the beautiful Visitacion Valley Branch Library. Then, the walk returns on Leland to the entrance to the Greenway and continues uphill through four blocks of the Greenway, ending at Campbell Avenue. This walk is a little more than a mile in length.

Our trio of tree geeks responsible for this tour is the same: Jason Dewees (author of Designing with Palms), Richard Turner (retired editor of Pacific Horticulture), and I’m Mike Sullivan, author of Trees of San Francisco.

 Numbered trees are labeled with common and scientific names and country of origin, all written in white chalk on the sidewalk; accompanying numbers, in blue, run from 1 to 41. White arrows on the pavement provide directions whenever a turn is needed.
