Petunia 'Ultra Crimson Star'

 

Petunia 'Ultra Crimson Star'

The Petunia flower can come in many different colours including red, white, yellow, blue and fuchsia, they can also be dual coloured or spotted. A most useful tender bedding plant, commonly sold in garden centers as pot and plug plants. You can sow at home but it needs to be started in heat in late winter. There are bush varieties ideal for pots and trailing varieties such as Surfinia and Million Bells which make great basket plants - a well fed Surfinia can cascade over 1 meter. The flowers go over discreetly, although they can be spoilt by heavy rain - pick off faded flowers if they are unsightly. Plant out after all danger of frost is past - late spring in the south to mid-summer in Scotland.
