But for some gardeners, the dream of those glorious yellow trumpets remains that, just a dream, and all they get are the long spikey green leaves.
Why is that? Why do daffodils fail to grow and what causes daffodil blindness? RHS, the Royal Horticultural Society has some sympathy with the disappointment caused by clumps of daffodils that have previously grown and flowered well but then begin to decline in flowering.

The RHS says daffodils need water and if the conditions are too dry, the growth will die down before the bulb is able to replenish. Leaves should not be removed too soon either, as this stops the bulb building up food reserves for the future.
In poorer, light soils, performance may rapidly decline without some additional nutrition. Shallow planting encourages bulbs to divide, which means the bulbs become too small to flower. Overcrowding can also lead to poor flowering.
The RHS suggest trying feeding the bulbs. If overcrowded groups of daffodils are not flowering, lift them when the foliage dies back in the summer. Improve the soil with organic matter and fertiliser and then re-plant with a good gap.
