Penstemon barbatus ‘Iron Maiden’ is a half-hardy perennial penstemon, with tall stems bearing bright scarlet flowers from midsummer to early autumn. As they’re not fully hardy, it’s advisable to avoid cutting back the old growth, which will provide extra protection, until the worst winter weather is over, usually around February and March. You can then cut it back hard to make way for fresh growth.
When planting, give them a light feed but don’t feed again – overfeeding will result in lots of leafy growth at the expense of flowers. To prolong flowering, cut back spent flower stems.
For best results, grow Penstemon barbatus ‘Iron Maiden’ in light, well-drained soil in full sun.
