We had a huge Pinus radiata in our garden, now gone, with a deep thatch of pine needles and 'duff' (decomposed needles). We had a pot of Cyc. repandum underneath which dropped its seeds over-board unknown to me. Now the seedlings have spread into a generous colony, not so big as Alisdair's but very pleasing. Looking about we find seedlings in our mown grass 'lawns', in paths and under old camellias. Elsewhere coum and hedrifolium have spread widely and I have planted out seed raised africanum, cyprium, corsicum, libanoticum, pelopponesiacum and pelopps lividum. All seem to be settling quite happily.
