Beautiful Plants For Your Interior
Those purple leaves on your potato plants aren’t just odd—they’re a red flag. I’ve seen this happen when nights dip below 50°F or when the soil’s missing phosphorus.
Here’s the thing—this color change can also signal glycoalkaloid buildup, which isn’t safe for pets or people. We’ll figure out what’s causing it and how to fix it before it spreads.

- ● Safety goggles: 1 pair (ANSI Z87.1 certified) for eye protection.
- ● Purple potato plant: 1 mature plant (with visible leaves) for analysis.
- ● Pruning shears: Sterilized stainless-steel (1 pair) for clean leaf samples.
- ● Sample containers: 3-5 airtight, labeled glass jars for storage.
- ● Disposable bags: 2-3 sealable plastic bags for waste.
- ● Lab coat: 1 long-sleeved, fluid-resistant coat.
Tips and Common Mistakes
These practical insights will help you confidently manage purple foliage in your garden.
Visual Identification: In Step 1, pay close attention to the pattern of purple coloration. Uniform purple across all leaves typically indicates a natural variety, while spotty or mottled purple often signals stress or disease. I always compare several leaves before making a determination.
Safety First: For Step 3, don’t underestimate the importance of physical barriers. Even well-trained pets may be tempted by foliage, and it’s better to prevent access entirely. Chicken wire works well, but make sure it’s securely fastened at ground level to prevent digging underneath.
Hilling Technique: During Step 4, when hilling soil every 2-3 weeks, use a gentle hand to avoid damaging stems. I find that hilling in the evening when plants are less stressed works best, and it’s crucial to cover all exposed tubers to prevent greening.
Storage Conditions: In Step 5, maintaining that 45-50°F temperature range is critical. I use a root cellar or dark basement corner with good ventilation. Remember that refrigeration is worse than room temperature storage for potatoes, as it can actually increase toxin development.

Frequently Asked Questions
1
Are purple potato leaves safe to eat?
No, purple potato leaves contain toxic glycoalkaloids like solanine, which can cause nausea, vomiting, or worse if ingested. Always avoid eating any part of the potato plant except the tubers.
2
Can pets safely eat purple potato leaves?
No, they’re toxic to pets too! Glycoalkaloids in the leaves can lead to digestive upset, lethargy, or even neurological issues. Keep leaves away from curious pets and compost them securely.
3
What should I do if my pet eats purple potato leaves?
Contact your vet or a pet poison hotline immediately. Monitor for symptoms like vomiting or weakness, and bring a sample of the plant for identification.
4
How can I safely dispose of purple potato leaves?
Wear gloves, remove leaves, and dispose of them in sealed yard waste bags. Avoid composting if pets have access, as toxins may persist.
5
Are there safe alternatives to using potato leaves in my garden?
Yes! Use non-toxic mulches like straw or pine needles. For compost, stick to safe greens like vegetable scraps or grass clippings.
