Anne here, and today I'm talking about growing plants inside, in pots. Even though I've always had an outdoor garden, I've still loved growing pot plants indoors. And every winter, the cheerful splash of color from indoor flowering plants makes me smile. The color here is from a cyclamen, and each year I buy one or two that are about to start flowering, and their vivid blooms keep me feeling cheerful all through the gloom of winter. (This photo was taken last winter.)

For centuries people from all sorts of cultures have valued scented and flowering plants —Hanging Gardens of Babylon, anyone?— and bringing them indoors so that their fragrance and blooms could be enjoyed, perhaps also masking unpleasant smells.
From the 15th century, European explorers and colonizers brought home all kinds of "treasure" from the Americas, Africa, Asia, and Oceania — including botanical specimens — though few of these survived except under special conditions.
But as technology advanced to the point where whole buildings could be made of glass and steel, plants unsuited to cold Northern European climates — plants such as oranges, lemons, pineapples, and other delicate fruits — could be grown under glass.

By the 17th century, citrus trees were a status symbol among the wealthiest in society, and greenhouses and orangeries were built to protect these highly coveted specimens during winter. They might be called conservatories, orangeries, succession houses, or ferneries, depending on what they were growing. (The photo on the left is a gorgeous modern version of the Victorian style conservatory, from this site.)
Flowering spring bulbs, such as narcissi, hyacinths and tulips, grown in pots, could easily be brought indoors when in flower. By the end of the 17th century, these were being ‘forced’ to flower early in winter by starting off the bulbs in the warmth of indoors. Hyacinths, with their heady fragrance were particularly popular.
