'Big Brother' has very large, light yellow flowers.
As for digging bulbs, well it depends... on how many I have (if I have many it's okay to destroy some) and how deep down they are.
For shallowly planted bulbs a digging fork works reasonably well, but if the bulbs are deep down, I often dig sort of a "mining shaft" at the side of the group and a little deeper than the bulbs are. The "mining shaft" helps in getting the digging fork further down into the soil and therefore reduces the risk of "spearing" the bulbs.
If I want to be really careful I use my hands to push the soil from around the bulbs down the "mining shaft". When the "mining shaft" is full I empty it and repeat the procedure. When I finally uncovered the bulbs, I can either use my hands to lift them or a digging fork. Of course I have light soil, so this makes for easy digging!
