Description How to Grow More Info Delivery
Sumptuous, tubular, blackcurrant blooms rise in elegant spikes above clumps of narrow foliage for literally months on end. Penstemon 'Raven' is a striking cultivar, particularly when teamed with pale flowered perennials such as anthemis and gypsophila. Like all penstemon it is a magnet for pollinating insects earning it a place in wildlife areas too. This semi evergreen perennial is easy to grow and holds an RHS AGM for its garden performance. Height: 90cm (36"). Spread: 30cm (12").

Flowering Months
Feed and water penstemons regularly until they are fully established. Once established they are reasonably tolerant of drought and will require little maintenance. Deadhead faded penstemon flowers to maintain the plant's vigour and encourage further blooms to be produced. In cold areas apply a dry mulch of bark chips of straw around the crown of each plant in autumn. Leave the old foliage intact until spring to protect plants during winter.
Grow penstemon in a sunny or semi shaded position on fertile, well drained soil. Penstemons can tolerate dry soils once established but dislike heavy soils that are particularly cold and wet in winter. Improve heavy soils by adding plenty of coarse grit prior to planting.
