Penstemon Collection

May is one of the best times to plant Penstemon. Planting them just after the last of the frosts will give them just enough time to establish a good root system before they start putting on flower bud. 

These reliable border perennials have a long flowering season and come in wide range of colours. Rosy has chosen to concentrate on producing many of the older cultivars which have a proven track record.
