Once houseplants become more of a consuming hobby than a passing pleasure, you will begin to look for more ways to feed your passion. One option is to start a collection of a particular type of plant, whether a large and diverse groups such as cacti, or a smaller interesting group like African Violets (shown).
Start by grouping your plants to find an arrangement that pleases you.
The design will look more interesting if you can create a cascade effect using florist's foam to build up different levels. Build up the back of the display with the foam first. Fill in the spaces in front in steps. Try the plants for size so that you can use more foam beneath the pots if needed.
Arrange the plants to look as though they could be growing as a natural group and not in straight rows. Fill the spaces between the pots with moss.
When selecting a container you have many options. Match the color of the pot to the accent colors in the room. Do you have bright red pillows? Then select a bright red planter to compliment and draw your attention to the brightness. Do you have a rattan table? Then use a bamboo theme planter. Is everything natural with neutral colors? Stick with a clay terracotta planter. It's a natural product that is lovely with sun baked terracotta color tones.
To find the best range of plants do not go to just one garden nursery. Hunt for specialists for imaginative and superior items not seen everywhere else. Plant early in spring when the selections are the best.
