Lilac Bloom Oxalis Bulbs

Oxalis triangularis — Lilac Bloom. Standard purple shamrock flowers sparingly — a couple at a time, easily lost against the foliage. This selection carries noticeably more open flowers at once, and they are a shade paler, so they register.

Flowering starts a little earlier in the season too, which matters if you are growing it for a specific date rather than for the foliage alone.

The leaves are the usual deep violet triangles, so you are not trading foliage quality for the flower count — you are getting both.

What you get

• Free flowering — several pale lilac blooms open together.
• Earlier to flower than standard purple shamrock.
• Deep violet triangular leaves retained underneath.
• 6–12 in, indoors or outdoors in zones 8–11.
• Dormant corms, cleaned and 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.
