I planted a few tuberoses 5 years ago. I planted them in pots. They grew fat clumps of grass-like leaves and bloomed the first year. After that, I planted them in a sheltered flower bed. The plants survived two more years, but did not bloom again. After that, I took them out. I live near Beaufort SC.

Have you posted your question on the bulb forum?

No, but I will. Thanks!

Mine have returned for two years now. I have the single variety which is recommended for the coastal south. The double is less reliable. They get some shade and plenty of moisture.

Mine were double and they didn't come back...
