Plant Details

A woody Penstemon which forms a low mound absolutely smothered in flowers throughout summer. The flower colour is predominantly blue, but overlaid with tints of pink and can occasionally be shades of purple and pink. Ideal for front of border or rockery situation.

Penstemons really are fantastic plants for any garden. They don't seem to suffer from any pest or disease and even the slugs avoid them. On top of that, they flower for months on end, right into autumn when many other plants have given up for the winter. They look equally at home in a traditional cottage garden, or a stylish modern design.

The flowers of 'Heavenly Blue' can vary in depth of blue depending on the light levels (i.e. on a sunny day the blue is not as strong as on a cloudy day). Also, poor soil tends to bring out a deeper blue in the flower than very rich soil. 

Loved by bees.

Happy in full sun but will tolerate partial shade without problems and this situation may increase the quality of the flowers. Most soil types are fine, including quite dry.

Height: 30cm



All our plants are supplied in 9x10cm pots unless otherwise specified. Plants in this size pot establish quickly in the garden and often outpace plants in bigger pots planted at the same time. We do not sell 'plug plants' because those need to be grown on before planting. Our potted plants can be planted immediately, unless otherwise noted, or you can leave them in their pots until you are ready to plant. We grow everything we sell ourselves, in our nursery in the Buckinghamshire countryside.
