My experiment worked! In the same bed as I planted daffodil bulbs, I put some nerine bulbs, thinking that since daffodils are spring-flowering and nerines are autumn-flowering, they might co-exist and provide colour in the garden twice a year.
I love bulbs poking their little heads through and coming up on their stalks to then reveal their true beauty as they come into bloom.
The same area in spring looked like this:
From the golden yellow of the daffodil we now have the contrasting hot pink of the nerine.
