Investigate specimens that reflect, absorb or bring light into the garden.

Host Jamie Durie visits the renowned Ruth Bancroft Garden in Walnut Creek, California, to take a closer look at specimens that reflect light, absorb light or bring light into the garden. Meanwhile, gardening correspondent Paul Epsom is in New York City searching for a cleaner, greener Big Apple. The city is attempting to shrink its carbon footprint, and one of the ways it’s succeeding is through the “Million Trees” initiative. The New York Restoration Project is behind this effort — planting trees one at a time — and it’s starting to make a real difference. Finally, Chef Michel Nischan creates a delicious, healthy “three sisters” succotash featuring beans, corn and pumpkin.
