From our perspective, we spider plants (Chlorophytum comosum) are a resilient and adaptable species, but we have our origins in the coastal forests of South Africa. This means we are fundamentally a tender perennial, thriving in warm, stable conditions with dappled sunlight. Our ideal temperature range is a cozy 70-90°F (21-32°C) during the day and not much below 50-55°F (10-13°C) at night. We are not equipped with a natural defense against frost; our succulent roots and leaves are highly susceptible to freezing, which causes irreparable cellular damage. Therefore, our ability to live outdoors in the US is entirely dependent on your specific local climate and the time of year.
For many of us living as houseplants across the US, moving outdoors for the summer is a delightful treat. Once nighttime temperatures are consistently above 50°F, you can safely move us outside. We will flourish in a location that mimics our natural understory habitat: bright, indirect light. A shaded patio, a spot under a tree with a high canopy, or a north-facing porch is perfect. Direct, harsh afternoon sun will scorch our leaves, leaving unsightly brown marks as we lack the protective coatings that true sun-loving plants possess. The increased air circulation outdoors often helps us grow more vigorously, and our famous "spiderettes" or "pups" may proliferate with even greater enthusiasm.
The vastness of the US climate presents a clear yes, no, and sometimes answer to this question. In USDA Hardiness Zones 9-11, which include parts of California, Florida, and the Gulf Coast, we can potentially live outdoors year-round as perennial evergreens if planted in a sheltered location. However, even these zones can experience unexpected cold snaps that would require us to be protected or brought inside. In Zones 7-8, it is a significant gamble, and we would require heavy mulching for root protection, though survival is not guaranteed. For Zones 6 and below, we absolutely cannot survive the winter outdoors. The freezing temperatures would be fatal. Furthermore, in all regions, we must be mindful of heavy rain and wind, which can physically damage our leaves and waterlog our roots, leading to rot.
To ensure we not only survive but thrive outdoors, a few key considerations must be met. Firstly, the light must be right—always filtered or indirect. Secondly, our potting mix must be exceptionally well-draining. While we appreciate consistent moisture, our roots abhor sitting in water. A pot with ample drainage holes is non-negotiable. You may find we require more frequent watering outdoors due to wind and heat, but always check the soil first. Finally, please be vigilant for pests. While we are largely trouble-free indoors, outside we can become a target for aphids, spider mites, and mealybugs. A regular visual inspection of our leaves, especially the undersides, will help keep us healthy.
