Perfect for Evening Garden Enjoyment
Here’s where the Colorado four o’clock really shines – it’s designed for evening entertainment. While most flowers close up shop as the sun sets, this beauty is just getting started. The flowers open in late afternoon (hence the four o’clock name) and stay open through the night, making it perfect for gardeners who want to enjoy their outdoor spaces after work or during evening gatherings.
Pollinator Powerhouse
The timing of this plant’s blooms isn’t just convenient for us humans – it’s a lifeline for evening pollinators. Colorado four o’clocks are particularly beloved by sphinx moths and hummingbirds, providing crucial nectar sources during evening and nighttime hours when many other flowers have closed. This makes it an excellent choice for pollinator gardens focused on supporting diverse pollinator communities.
