Q.Flowering New Zealand Flax in Sacramento California
Hi, here are pics of our flowering Flax in sunny, hot Sacramento California! This is the first time the flax have flowered. The plants may be 20 years old, they get as you can see full afternoon sun next to the green house. It appears there are both male and female parts, some yellow and some white. We are quite happy to see the huge tall flower stalks, some at least 4-5 feet long and the hummingbirds had quite a feast. Hope you enjoy our pics. There is still dried flowers that could be harvested if you want some. JJ 916-224-1402 email4JJ@yahoo.com
