Wine Dark Oxalis Bulbs

Oxalis triangularis — Wine Dark. Most purple shamrocks sulk in strong sun and bleach toward green. This one does the opposite: given four or five hours of direct light the foliage warms into a glowing magenta-wine.

It is the same species, just a selection that holds colour under more light, which makes it the practical choice for a south-facing sill or a sunny patio where the softer forms wash out.

The pink flowers open flat and wide in sun and close by afternoon, so the best display is mid-morning.

What you get

• Magenta-wine foliage that intensifies in direct sun.
• Sun-tolerant — holds colour where other forms fade to green.
• Wide-opening pink flowers, best in morning light.
• 8–12 in, good for a south-facing windowsill.
• Dormant corms, graded before dispatch.

How to grow it

• Plant: 1–2 in / 3–5 cm deep, pointed end up, 3–4 in apart in a pot with drainage. Soak the corms for an hour first — they wake up faster.
• Light: bright, indirect light or a few hours of morning sun. Strong light keeps the purple deep; deep shade turns the leaves green.
• Water: keep evenly moist while growing, then let the top inch dry between waterings. Never leave the pot standing in water.
• Temperature: 60–75°F indoors. Hardy outdoors in USDA zones 8–11; elsewhere grow it in a pot and bring it in before frost.
• Dormancy: the leaves die back every few months — that is normal, not death. Stop watering for 4–6 weeks, then start again and it regrows from the corms.

Shipped dormant as graded corms, cleaned and ready to plant. Dispatch in 5–7 working days. Leaf colour and flower shade vary with light, season and the age of the corm — the first flush after planting is usually the darkest. Keep away from cats and dogs: oxalis is high in oxalic acid and is not pet-safe if chewed.
