Q. Who is Mr. Smarty Plants?

Title: Will frozen non-native agapanthus come back from freeze in Austin?
Answered by: Barbara Medford

QUESTION:

I don't know if its a native plant, but my agapanthus got frozen in our recent cold weather. Will they come back; should I trim off the tops?

ANSWER:

From Botany. com, we found this article on Agapanthus - African Lily. The common name probably gives you a good clue; this plant is native to South Africa. It is apparently semi-evergreen in mild climates, but the recent quick freeze in Austin does not represent "mild."

From Easy to Grow Bulbs.com we found an article on planting and caring for agapanthus, which included this phrase:

"In cold areas, bring your plants indoors when night temperatures begin to drop to the low 40s."

Sadly for your plants, this illustrates once more the principle behind the recommendations of the Lady Bird Johnson Wildflower Center for planting only those plants native not only to North America but to the area in which they are being grown. Even in very mild winters, Austin will have temperatures below 40 deg. numerous times.
