Heuchera 'Purple Petticoats' · also called Coral Bells 'Purple Petticoats', Alumroot 'Purple Petticoats' · flowering

Heuchera 'Purple Petticoats' is a striking evergreen perennial with deeply ruffled, heavily frilled dark purple leaves that hold their colour through winter. It produces small cream to white flowers on tall stems in summer. Its dramatic ruffled foliage makes it an excellent edging and container plant. Non-toxic to pets per the ASPCA.

Mature size: 25-35 cm tall, 30-45 cm wide

Growth rate and years to mature
