Solanum pyracanthos (Porcupine Tomato) [10 Seeds]

(1 customer review)


Germination Information: Sow the seeds 1/8 to 1/4 inch deep in a warm, bright place in early spring. In 2021, I sowed seeds from 2019 on March 16 on a heat mat under lights, and the first sprouts appeared on April 5. In 2022, seeds I sowed on March 6 (under lights but not on a heat mat) started sprouting on March 22, with more seedlings appearing over the next 2 weeks. Transplant to your garden after your last frost date. I usually wait until nights are at least 50°F, as getting chilled can really slow down the plants’ growth. If your plants have time to produce fruits and ripen them fully before frost, you might find some self-sown seedlings the following year.

Porcupine tomato (Solanum pyracanthos, or S. pyracanthum, or S. pyracanthon, depending on which authority you follow) is a real plant-geek’s plant. It does have ornamental, rich purple flowers, but its key feature is the bright orange spines that adorn the lobed, gray-green leaves and the slender, branching stems. The flowers develop into yellowish green, marble-sized fruits topped with a spiny cap. Though “tomato” is in the common name, this isn’t something you’d grow to eat. Porcupine tomato usually gets 2 to 3 feet tall in my garden or a mixed container planting, but when it gets pampered with regular watering and fertilizing in a pot by itself, it can get 4 to 5 feet tall if not kept smaller with careful pruning. Full sun. Usually grown as an annual (it’s perennial only in frost-free areas).

Collected starting in late August 2022. At least 10 seeds. One packet per customer. Shipping to US addresses only.
