Three years ago I harvested some nasturtium seeds and threw them in the front yard. I haven’t watered them this year given that we are in a severe drought. This week they were in full bloom and contrasting nicely against an old brick wall. These flowers drop seeds which, in turn, produce more nasturtiums; however, in the current dry conditions the growth of new flowers is limited to shady areas.
While nasturtiums aren’t first choice of our honey bees–they prefer lavender and ivy–they will collect nectar from them as it is a short fly from these flowers to the hive.
