Description
Oxalis spiralis ssp. vulcanicola ‘Zinfandel’ (Zinfandel™ Volcanic Sorrel)
Bring dramatic color and year‑round interest to containers, hanging baskets, or as a low‑growing groundcover with Zinfandel™—a stunning oxalis cultivar prized for its rich plum‑purple foliage and bright yellow blooms. Zinfandel™ features deep wine‑red to nearly black shamrock‑shaped leaves that hold their intense color in part‑sun to full‑sun exposure, forming a dense, cascading mound 6–10″ tall by 10–12″ wide. Delicate five‑petaled yellow flowers appear intermittently from spring through summer, rising just above the foliage on slender stalks—no deadheading required.

Care Guide
- Light: Bright, indirect light to morning sun. In hotter climates, shield from harsh afternoon rays to prevent leaf scorch.
- Water: Keep the soil evenly moist but never water‑logged. Allow the top ¼″ of soil to dry before watering again.
- Soil: A well‑draining, organic‑rich mix (peat‑based or coco‑coir blend) ensures tubers don’t sit in water.
- Temperature: Thrives between 60–75 °F (16–24 °C); tolerant down to 28 °F when kept dry.
- Humidity: Prefers moderate humidity (40–60%); tolerates average home levels.
- Fertilizer: Feed monthly during active growth (spring–summer) with a balanced, water‑soluble fertilizer at half strength.
- Propagation: Divide tuber clusters in spring or early fall—each segment with at least one growth eye will form a new clump.
- Maintenance: Remove spent flower stalks to tidy appearance; divide clumps every 2–3 years to rejuvenate foliage color and vigor.
Uses & Styling
Ideal as a vibrant filler in mixed containers, a trailing element in hanging baskets, or a striking border plant under warm‑season shrubs. Its sterile, non‑invasive habit makes it garden‑friendly and maintenance‑free.

How do you ship your plants?
We carefully package each plant with love by hand right from our shop in Brooklyn. Extra steps are taken to ensure that every leaf arrives in pristine shape by using polyfill and encapsulating the plant in a protective paper sleeve. The soil is also hydrated before shipping so that the plant has plenty of water for it's travel to your doorstep. We offer several shipping speeds, so please choose the one that you feel comfortable with depending on your location.
Will my plant look like the one on the website?
Will my plant look like the one on the website?
Awesome question, we're glad you asked. Given the nature of our plant shop, we're constantly moving plants in and out of the shop, making it difficult and borderline impossible to keep an exact picture of each plant. In addition to the constantly rotating crop, we often grow in batches of 6, 12, or sometimes more! With this quantity we are unable to take a photo of each and every plant. The photos that we attach to each product listing is going to be of a plant that represents the average size and fullness of that set of plants. Some may be slightly larger or smaller, but in general, similar.
Do you include heat packs with your plants?
Do you include heat packs with your plants?
We offer Heat Packs for sale separately from the plants in 40, 60 and 72 hour increments. Please add a heat pack or two to your order if you live in an area where your order may be affected during transit by cold temperatures. We are not responsible for orders that are placed and damage is incurred to the plant if a heat pack is not purchased.
Which heat pack should I choose?
Which heat pack should I choose?
Heat packs come in three different increments, so please choose the appropriate hour increment depending on the speed of shipping that you choose during checkout. For example, if you choose a cheaper shipping option that will take longer, please select the 72 hour heat pack. If you've chosen a shorter method of shipping, the 40 or 60 hour increment would work! We like to encourage our customers to always get more than you need, just to be on the safe side!
