14. Autumn Joy’ Purple Spruce

If you are looking for the most sustainable solar plant, this perennial is your best choice.


Plants adapted to the orientation of the porch

Most often, the porch is oriented south-east to south-west for maximum light, which can be tempered in summer with blinds or shutters and good ventilation.


The plants in the porch are therefore mostly full sun plants.

This great luminosity allows for generous flowering and even fruiting that is difficult to obtain in the house.


Plants fearing frost and winter humidity

Even unheated, the porch is a space open to the inside that usually benefits from the warmth of the house. It protects plants from frost and excess winter humidity.


This gentle warmth can be maintained at the desired temperature by an auxiliary heater equipped with a thermostat, especially if it houses exotic plants of tropical origin that hate temperatures below 59°F. If porch life is successful for tropical plants, take care to control their growth or you may feel suffocated.


A citrus fruit porch

Citrus fruits enjoy an unheated porch where they appreciate the brightness, the protection from frost in cold regions or the dry air of the interiors. Calamondin, kumquat or lemon tree will embalm the porch with their many fragrant flowers.


Water them with non-lime-sensitive water. Repot only when they are really cramped for more flowers and therefore more fruit!


Some tips for an unheated porch

  • Use demineralized water or rainwater for all spraying in canopies. This will prevent the glass from staining with limescale, reducing the light available for plants;
  • Be careful that the burning rays of the sun do not burn the foliage of your plants, shade during the hottest hours of the day with blinds or sun curtains ;
  • Refresh your porch by wetting the floor (preferably tiled) every morning, because the temperature tends to rise quickly;
  • Ventilate the conservatory as soon as the outside temperature allows it to avoid a feeling of permanent dampness;
  • The depolluting plants have shown in laboratory studies the ability to capture air pollutants in their tissues. However, this capacity has not been scientifically proven in real-life situations*.
  • In winter, reduce watering (never more than once a week) and stop spraying.



If you are lucky enough to own a porch, turn it into a conservatory. So, even in the middle of the bad season, relax amidst the lush greenery and foliage of tropical plants. In a greenhouse heated in winter, don’t deprive yourself of exotic plants and their spectacular flowering!


In this room, an extension of the house on the garden, or in your greenhouse, the brightness is the strongest. It is in this place that the plants that spend the summer outdoors overwinter. It is also here that you will be able to benefit from flowering and fruiting out of season (if the room is a heated minium).
