More weeds in the garden!
Oenothera, we called them "night blooms", can be a major weed. When I was very young my best friend and I grew them in our gardens. He passed to the other side many years ago. I keep them in the garden (under control!). When the flowers open in the evening giving their wonderful fragrance I am reminded of a wonderful fishing companion!
Verbena bonariensis, also a weed, attracts beneficial insects to the farm and are very drought and heat tolerant. They bloom all summer so they stay around.
Origanum microphyllum, not a weed, but good cover for dormant bulbs in our garden.
