I planted mine in the ground and I have no sin of flowers yet either. Maybe next month?

My acidanthera has been blooming since early last week--I planted more two weeks apart, and they should be popping any day now.We've had really high heat--I don't know if that has made a difference. Cathy

I have some planted in the ground that are forming buds, but the ones planted in pots have not formed buds yet. I'm sure they're not far behind.

I have mine planted in pots. Planted at 2 week intervals the very first are blooming. My experience is one day there are no signs of bloom then overnight there are buds. /Abi
