Longlobe Four O’Clock: A Desert Native That Blooms When Others Sleep
If you’re looking for a low-maintenance native plant that puts on a show when most flowers are calling it quits for the day, meet the longlobe four o’clock (Mirabilis tenuiloba). This charming desert native has figured out that the best parties happen after dark – and it’s ready to prove it in your garden!

What Makes Longlobe Four O’Clock Special?
The longlobe four o’clock is a true southwestern native, calling Arizona and California home. As a perennial member of the four o’clock family, this plant has adapted beautifully to desert life, staying compact and tough while still managing to be absolutely delightful.
This little charmer grows as a low shrub, typically staying under 1.5 feet tall and never getting taller than 3 feet even at full maturity. Think of it as the perfect front row plant – it won’t block your view of taller beauties behind it, but it definitely deserves a starring role in your landscape.
Evening Entertainment: The Four O’Clock Show
Here’s where things get interesting (and slightly magical). While most flowers are photogenic during the day, longlobe four o’clock saves its best performance for late afternoon and evening. The small, funnel-shaped flowers – usually dressed in lovely pink to magenta tones – open as the day cools down, creating a sunset spectacle right in your garden.
This evening routine isn’t just for show. Those night-blooming flowers are perfectly timed to attract moths and other nocturnal pollinators, making your garden a bustling hub of nighttime activity. It’s like having a secret pollinator party that most gardeners never get to witness!
Perfect for Desert and Xeriscape Gardens
If you’re working with a desert landscape, rock garden, or trying your hand at xeriscaping, longlobe four o’clock should definitely be on your plant list. This native knows how to handle the heat, drought, and challenging soils that make many other plants throw in the trowel.
Use it as:
- Ground cover in desert-themed gardens
- Border plantings along pathways
- Rock garden specimens
- Native plant garden features
- Low-maintenance landscape accents
Growing Conditions: Easy Does It
One of the best things about longlobe four o’clock is how little fuss it requires once you understand its preferences. This plant thrives in USDA hardiness zones 8-10, making it perfect for warmer climate gardeners.
Here’s what makes this native happy:
- Sunlight: Full sun – the more, the merrier
- Soil: Well-draining sandy or rocky soils (clay soil will make it cranky)
- Water: Drought tolerant once established – less is definitely more
- Drainage: Essential – soggy feet are this plant’s biggest enemy
Planting and Care Tips
Getting longlobe four o’clock established is refreshingly straightforward. Plant in fall or spring when temperatures are moderate, and choose a spot with excellent drainage – think of it as preferring a sandy beach over a muddy pond.
The golden rule with this native is simple: when in doubt, water less. Once established, it can handle long periods without supplemental watering, making it perfect for water-wise gardens. Overwatering is more likely to cause problems than underwatering, so err on the side of caution.
Why Choose This Native?

As a true native of the Southwest, it supports local ecosystems and provides habitat for native wildlife, particularly those night-flying pollinators that often get overlooked in garden planning.
