This unusual biennial makes a big rosette in the first year, flowers the second year and then dies BUT leaves behind seedlings. So while it's not strictly a Perennial, it does reproduce itself. It has spikes of deep rose-red flowers. The foliage is dark green with a coarsely hairy surface and these are like a 5 star restaurant to bees and butterflies. Said to be hardy to -20C, it is most important to plant them where the ground is sharply drained & stony as more succumb to wet than cold. If in doubt, start them off indoors for their first year and plant them out in the second. H 2-3' 2 litre pot.

This charming perennial wallflower was discovered originally in the garden at Greenway, Agatha Christie's Devon home. It was given to us by Poppet Heaton, a niece of Agatha's son in law. Poppet died suddenly in 2009 and her death was a great blow to her dozens of friends, among whom were several nurserymen who knew her as an expert and avid gardener. Those of us to whom she gave this agreed to name it in her memory. A holder of the National Collection has confirmed that this is a hitherto unknown variety.

Given to us by a friend who had worked on a local estate, we're still trying to identify positively this Eucomis. It's tall, it's stately and it looks fabulous in urns and pots. Dies down in winter, resurges every year in this garden. 2l.pot
