Spring wildflowers of Van Cortlandt Park, Bronx

Fordham Gneiss, one of the oldest rock formations on Earth, characterizes Van Cortlandt’s dramatic cliffs in the Northwest Forest. We'll explore the oak-hickory forest on rocky heights overlooking valleys dominated by tulip trees (Liriodendron tulipifera) and century-old oaks, with early lowbush blueberry (Vaccinium angustifolium). Ground layer wildflowers are extraordinarily diverse in the Northwest Forest. There is bloodroot (Sanguinaria canadensis), trout lily (Erythronium americanum), Dutchman's breeches (Dicentra cucullaria), and wood rush (Luzula multiflora).

We'll walk eastward to Croton Woods, stopping to see Mayapple (Podophyllum peltatum) to the woodsy wildflower slope with wild ginger (Asarum canadense), cut-leaved toothwort (Cardamine concatenata) - see above pic -, and more bloodroot (Sanguinaria canadensis). We'll ford a brook and walk to the old Aqueduct Trail to see smooth yellow violet (Viola eriocarpa) and Canada violet (Viola canadensis) and try to relocate the red mulberry (Morus rubra) I saw 10 years ago.
