Indoor/House Plants : If you're reading this you're human (presumably) and if you're human, you may have a room that you think of as warm, comfortable and light. A plant might disagree with you. It'll probably think your room is dark, dry and not particularly comfortable. Living in a pot in a house is no place for a self respecting plant but fortunately there are a few that don't mind. Some are just incredibly tough (Phoenix canariensis, Agave americana) but most are forest floor plants with large leaves (an adaptation to low light) such as Alocasia, Zantedeschia and Gunnera. Some people are surprised by our suggestions but with skill and space, any plant that's adapted to low light is worth trying as a house plant. Some can get quite big but they either need a large house or office or atrium or they need to get cut back from time to time. Two commonly used 'Indoor/House Plants' are Kentia Palms (Howea forsteriana) and Yucca (Yucca elephantipes). Left to their own devices, Kentias can grow to over 30ft and Yuccas to over 20ft.
Bearing in mind the important understanding that there's no such thing as an Indoor/House Plant (or Conservatory Plant, or Pot Plant or Wall Shrub for that matter), much can be learnt by observing the behaviour of plants indoors. Some might respond to electric lights nearby (the wavelength of light used by plants is little understood), some might enjoy a spell outside from time to time, some will do better by a window, all might get bugs (see Pests and Diseases on this page), all will benefit from having their leaves dusted and all need a saucer to sit in to stop the floor getting wet.
Like most establishments, the House Plant Industry is conservative. Understandably, they stick with what they know but experience has shown us that there are huge numbers of plants worth trying and occasionally one is genuinely surprised at what works and what doesn't. The plants we list in this category have all been tried with conditional (obviously) success. There are more possibilities than Swiss Cheese Plants, Rubber Plants, Ficus benjamina and Poinsettias.

General Point about Plant Hardiness: The commonly held belief that it's better to 'plant small' is perfectly true with herbaceous plants, but not necessarily true with woody plants. They need some 'wood' on them to survive severe cold - so plants of marginal hardiness in very cold areas should really be planted LARGER, rather than smaller, wherever possible.
