Zone 7 crinums?
My dad bought a whole "bulb" bundle kit that had some crinums in it from earlier in the summer that we didn't get a chance to plant. I've read some crinums are hardy to zone 7, which we technically are, though Maryland in general I would say is more of a 6b-7a cusp. I don't know if they're the hardier type, but is fall an okay time to plant them? I'd hate for them to rot/dry out and go to waste. Is rule of thumb plant deep and mulch well?
Also, the ideas of crinums in general seem fascinating, not many bulbs repeat bloom or bloom more like a perennial. Any named varieties of crinum that do particularly well in the Mid-Atlantic region or are worth mentioning? Thanks!
