Penstemon 'Pensham Amelia Jane'
- Position: full sun or partial shade
- Soil: fertile, well-drained soil
- Rate of growth: average
- Flowering period: July to October
- Flower colour: red with a white throat
- Hardiness: borderline hardy (may need winter protection)
Originally bred by Edward Wilson, of Pershire Plant Raisers, the Pensham Penstemons were bred to withstand lower temperatures and inclement weather, as well as produce beautifully coloured flowers for a longer period than most of the other varieties. This is one of the most popular forms, with large, white-throated, cherry-red flowers, that appear on upright stems for many months from midsummer. It looks spectacular when planted in swathes through a late summer border, where its sizzling colour will add oomph to 'hot' themed beds.
- Garden care: Remove the faded blooms regularly to prolong flowering. Apply a dry mulch around the base of the plant to protect the roots from frost damage in autumn. Leave the old foliage to protect the new shoots from frost and then cut it back by a third in spring.

Q:Powdery mildew on my plants
Hi, I wonder if your plant doctor may be able to answer a query for me. I have bought a few Verbenas from yourselves and they all seem to have suffered the dreaded powder mildew problem. I have sprayed with a recommended product and discarded the affected leaves but don't know if I have sorted the problem or not sufficiently? I read that this often affects plants that are under stress, - I did keep all the plants potted up (although some in larger pots than at purchase) close to each other for some time. I wonder if that might be why this happened ? Any advice would be welcome. They are now all in the garden and hopefully will thrive. SueAsked on 9/3/2009 by Sue Hulkes
A:Hello Sue, Powdery Mildew is caused by the plants being too dry and having poor air circulation, which are usually made worse when the plants are growing in pots. It sounds as of you have tackled it correctly, so they should improve.
