There was a recent comment about staking amaryllis. Last year, I bought some end-of-season "Double Record" bulbs that were in rather wretched shape. I potted up four of them in a communal pot. They produced flowers before they produced roots and when they got so topheavy they started bailing out of the pot, I staked them with standard orchid stakes, pushed deeply into the soil. It worked well to keep them upright through bloom - see below. The stakes are easily replicated with welding rod wrapped around a broom handle, by the way.
