Yes, an Aluminum Plant ( Pilea cadierei) can be grown outdoors, but only under specific climate conditions.
Outdoor Cultivation of Aluminum Plants
According to plant care guidelines, the Aluminum Plant is suitable for outdoor planting primarily in warmer regions. Specifically, Aluminum Plant can be grown outdoors in USDA Hardiness Zones 11a-12b.
Understanding USDA Hardiness Zones
USDA Hardiness Zones are a standard used to determine which plants are most likely to thrive at a location. They are based on the average annual extreme minimum temperature of a region.
- Zone 11a: Minimum temperature range is 40 to 45°F (4.4 to 7.2°C).
- Zone 11b: Minimum temperature range is 45 to 50°F (7.2 to 10°C).
- Zone 12a: Minimum temperature range is 50 to 55°F (10 to 12.8°C).
- Zone 12b: Minimum temperature range is 55 to 60°F (12.8 to 15.6°C).
These zones represent tropical or subtropical climates where temperatures rarely, if ever, drop below 40°F (4.4°C). The Aluminum Plant is sensitive to cold and will not survive freezing temperatures.
Finding Your Local Hardiness Zone
To determine if you can grow an Aluminum Plant outdoors, you need to know your local hardiness zone. You can typically find this information by:
- Searching online for "USDA Hardiness Zone map" or "What is my hardiness zone?"
- Entering your zip code on a hardiness zone finder tool provided by agricultural extensions or plant nurseries.
If your location falls within USDA Zones 11a through 12b, you can successfully grow Aluminum Plants outside year-round.
Conditions for Outdoor Growth
When grown outdoors in suitable zones, Aluminum Plants require:
- Sunlight: They prefer bright, indirect light or partial shade. Too much direct sun can scorch their leaves.
- Water: Consistent moisture is key. Water regularly, especially in hot weather, but ensure the soil drains well to prevent root rot.
- Soil: Well-draining soil is essential.
With the right amount of sunlight and water, you may also see your Aluminum Plant bloom outdoors. The plant grows vertically, with new growth emerging from the top.
In regions outside of Zones 11a-12b, Aluminum Plants are typically grown as houseplants or treated as annuals outdoors, being brought inside before cold weather arrives.
