A photo from “Native Plants for New England Gardens” by Mark Richardson and Dan Jaffe. Pictured: Blue lobelia (Lobelia siphilitica), once wrongly touted as a cure for syphllis, is a true blue flower, It’s shape gives bees a place to land, and it does well in moist to wet soils. What to do this week: Water Christmas trees daily. A humidifier is good for both plants and people. Outdoor lighting at night can disrupt the night/day cycles of owls and other wildlife, so install a timer to turn them off at bedtime.

A bestseller, this book tells you the best flowers for cutting and their needs, which can be very different than landscape plants’. “Seasonal Flower Arranging: Fill Your Home With Blooms, Branches, and Foraged Materials All Year Round’’ (Ten Speed Press, $25) by Ariella Chezar and Julie Michaels. Michaels is a former Boston Globe editor, and Chezar is an arranger and flower grower who also has pioneered the trend toward more fragile locally sourced bouquets as a “green’’ alternative to the overly familiar and rather stiff mass-produced flowers air-freighted […]
