Valentine treat: Mid -Winter in a Greenhouse

Deer tracks in the snow show where a hungry buck gazed wistfully through the glass at the tasty-looking green plants inside your greenhouse. Squirrel and rabbit tracks betray the presence of other wistful watchers that would envoy your greenery even more than you. That’s why they’re called greenhouses – because in winter they remain green […]

Timing is everything: in life and in seed starting

In February, a gardener’s fancy turns to starting seeds under lights: cabbages that can be transplanted into the garden in early spring; the earliest annuals, such as violas and snapdragons; and those that take a really long time, like petunias.

The Duchess of Northumbria, Lady Charlotte Percy (nee Clive) first succeeded in getting them to flower there, so the genus was called Clivia in her honor.
