Maybe mine is not the wild type. The roots will not survive and grow back the next Spring.
The seeds will overtake my garden area, very invasive here. Spent 2 years to finally get rid of them. They have the white flowers not yellow.
One year they bloomed all Spring long and no bees on them at all. Why? Because there are better options out
there for my bees. The wild mustard and other fruit trees provide more that they cannot resist. I ruled out the
rocket since. Dumped 2 big seed bags into the compost hole. Borage is invasive too that the bees like only in the summer dearth. When the wild mustard is blooming they don't even go near the blooming nearby Borage. The yellow blooming oxalis that others have seen bees on, mine will not work on those either as they have better options out there now. I can see that during a dearth the bees will work on what they have nearby. Try to grow some wild mustard in your garden and see if your bees will even go near the Arugula. If you need the wild mustard seeds I can send you some too.
Don't mix foreign bees into a virgin hive. She might get balled 100% of the time! When will you ever learn, huh?
