Anyone else growing broms outside in z8b/9a?
Last year I planted out a few Billbergia nutans in a microclimate area and they sailed through winter with zero damage. Our lowest temp was 23.8F. This year I have two big Billbergia pyramidalis planted out in the same area to see how they do. What are others growing outdoors in z8b/9a? What is the lowest temp they have been exposed to?
