What does Orange lily look like?

The orange lily grows from an underground bulb and stands between 20 and 90 cm tall, sometimes reaching up to 120 cm. Its leaves are narrow and pointed, and the upright stem holds one to five flowers. Each flower is bright yellow-orange with reddish-brown spots, about 4–6 cm long, and has six upright petals. The flowers are scentless, and the plant produces small bulbs along the stem in some varieties.

Where does Orange lily come from?

This lily is native to a wide stretch of Europe, from Spain through Finland and Ukraine. It thrives in sunny, grassy places on hillsides and in mountain meadows, often where the soil contains lime. The species name 'bulbiferum' refers to the plant’s habit of forming extra bulbs on its stem, which help it spread. Over time, local forms have been described in regions like the Maritime Alps and near Naples.

When and how Orange lily blooms

The orange lily flowers from May to July. It prefers warm, sunny spots and can grow in both calcareous and slightly acidic soils, often at elevations between 500 and 1,900 meters. The plant can be propagated by collecting the small stem bulbs, called bulbils, which fall to the ground and mature over a few years. These bulbils can also be removed by hand and planted elsewhere.

How Orange lily is used

People grow the orange lily in gardens for its striking flowers. It is also used as a symbol in Northern Ireland. However, the plant is highly toxic to cats, and even small amounts can be fatal if ingested or if pollen is licked from their fur. Caution is advised in homes and gardens with cats.

Kinds of Orange lily

There are two main forms: one in western Europe (var. croceum) and one in the east (var. bulbiferum), with the eastern type always producing stem bulbils. Smaller plants from the Maritime Alps and larger ones from near Naples are now seen as local forms of the western variety.

What Orange lily means

The orange lily carries symbolic meaning in Northern Ireland, where it is associated with the Orange Order. Its bright color and bold appearance have made it a recognizable emblem in that context. The plant’s toxicity to cats is also well known, making it a plant to avoid for pet owners.
