Re: Guerilla bee gardening
Both the blue and white flower type Borage are invasive. I've been trying to get rid of them for almost
4 years now. Every early Spring time they would bloom and can be overwintered quite easily here. Frost cannot
kill the young seedlings. Our environment is perfect for them invading every corner of the backyard if you let them.
The worst part are the tiny transparent skin poking needle like fine hairs. You would be asking for hours of itchiness if
you don't have a pairs of thick gloves to remove the dead plants. Imagine when a little dog or innocent kid playing at the
public land to be in contact with those innocent looking beautiful blooming plants. The seeds not in contact with sunlight will
stay dormant for years under the ground. Now I don't till the soil anymore instead to cover them with more compost making a raised bed. They are blooming nicely now and the bees are all over them. And so are the tiny 4 little seeds that come with every seed pods attached. I too like you have consider spreading them to the local creek and open fields. But after thinking about it further it is too invasive because of the many seeds one plant can produce in a season's growth. No other animals or insects will eat the plants either. They are drought resistant to an extent too. One month without any water they're still blooming and going strong. Just too many qualification to be on the invasive species list if it so qualify. Will be getting rid of them for good after the purple tansy and clovers got established this year.
Don't mix foreign bees into a virgin hive. She might get balled 100% of the time! When will you ever learn, huh?
