Have you ever grown an amarylis? I reckon they're amazing! I'm so convinced that I see it growing that I've put a marker in, to check its daily growth rate. I know that the bulb is huge, but the energy inside is tremendous.
Off down the garden first thing, to water the seeds I sowed last night. I hope they don't grow quite as fast as my indoor plant, though! Probably some sharp frosts still to come before these babies can venture into the great outdoors.
PS After 8 hours the amarylis has grown an inch!
