Petunias are popular bedding plants often spotted in enormous hanging baskets adorning pubs and and lamp posts.
Most bedding petunias are classed as either Multifloras or Grandifloras. Multifloras have a large number of smaller flowers that tend to fare better in inclement weather. Grandifloras have fewer blooms that are large and floppy, so are better grown in a sheltered spot where they’re less vulnerable to wind and rain.
There are hundreds of petunias to grow in a dazzling array of hues and patterns, so there are lots of combinations to be had with other plants. Several varieties of petunia are often seen combined with bidens and trailing lobelias.
