Additional Information

Overwatering young plants can be detrimental. Let the compost dry out before re-watering and give plenty of ventilation. Once established, dead-head regularly to encourage further flowering. Slug and rabbit resistant. Cut back in late spring, not autumn, to 25cm to encourage basal growth. For autumn deliveries please pot on 4 weeks and if the weather is good then you can pop then in the garden, with an extra mulch. If cold then please pop in a sheltered spot for overwintering in pots for the winter. Propagate by taking cuttings from non flowering shoots in summer.***Please note that for Penstemon Dark Towers that unlicensed propagation is prohibited. ******* Hardy perennial.

Hardy perennials are happy down to at least -5°C (23°F)
Half hardy perennials can withstand down to around 0°C (32°F)

"Thank you ladies for your beautiful plants.
Praise also, for the Bulrush Compost, of which I have purchased 8 bags during the past six months. It is superb and my garden has flourished.
Bless you,
Kind wishes"
