Pot Size: 2 litre (deep) Price: £20.00 Description: A glorious large architectural perennial, which we came across in Umbria Italy, growing in close proximity to a river, but well raised by gravel to avail the heat required to ripen the seed of this plant. Where many of the wide mound forming plants had grown into tall single stemmed plants to 2.5m, grey-green glaucous with few branches subtended by large inflated sheathes. With few linear leaves almost thread-like and large terminal umbels of flat seed, which were the result of the earlier yellow flowers. Easily grown in good drained fertile soils in good light, sometimes monocarpic.
