Lucky us – we found some tiny Daffodils still in flower on the top of the hills en route to Manteigas, Portugal – growing at 1450m in practically pure rock. Growing with them were tiny alpine bluebells.
It just goes to show that when all the books tell you to put grit underneath your bulbs when planting – it’s because they really like very good drainage and choose to grow right on PURE grit given the chance! In NZ the best thing to use in your pots or garden would be small, sharp gravel or pumice.
