  One of the most popular varieties of pink, and also hailed as one of the longest flowering. 'Gran's Favourite' is a 'laced' variety, which means the scented flowers are made up of two colours - with a contrasting centre and edge to the petals. This one has ruffled white petals with a splotch of deep purple-red in the centre and edge. It is sturdy and compact, and is best planted towards the front of a perennial border or rock garden - or in a pot.
  
  
• Garden care: Incorporate lots of well-rotted manure or garden compost into the planting hole. Apply a balanced fertiliser in spring and deadhead to prolong flowering.
