Fritillaria imperialis 'Aureomarginata' is an unusual and highly distinctive form of Crown Imperial, combining dramatic orange flowers with striking variegated foliage. Its tall, dark flower stems carry a crown of large, downward-facing orange bells, topped by a characteristic tuft of narrow leaves edged with creamy yellow.
Flowering in April and reaching around 60-90cm tall, 'Aureomarginata' makes an impressive architectural feature in spring borders. Unlike ordinary Crown Imperials, the foliage is an attraction in its own right, with each green leaf picked out by a contrasting yellow margin.

About Fritillaria 'Aureomarginata'
Crown Imperials are among the most dramatic of spring-flowering bulbs, and 'Aureomarginata' adds an extra dimension with its colourful foliage. Strong upright stems emerge in spring, developing a ring of large, pendant orange flowers near the top. Above the flowers sits a conspicuous crown of narrow leaves that gives Fritillaria imperialis its familiar common name.
The deep orange flowers contrast particularly well with the dark stems and bright variegated foliage. Planted amongst lower spring bulbs and perennials, the tall stems create a strong vertical accent above the surrounding planting.
Striking Variegated Foliage
The foliage is what really sets 'Aureomarginata' apart. Its long, narrow green leaves have prominent creamy-yellow to golden margins, producing a much brighter appearance than the plain green foliage of typical Crown Imperials.
The variegation occurs both on the leaves arranged around the stems and on the distinctive leafy crown above the flowers. This means the plant remains visually interesting even before its orange flowers fully open.
Where to Grow Crown Imperial 'Aureomarginata'
Choose a warm, sunny position with fertile, well-drained soil. Light partial shade is also suitable, but good light helps encourage strong growth and flowering. Crown Imperials dislike sitting in cold, waterlogged ground, particularly while the bulbs are dormant.
Their height makes them particularly effective towards the middle or back of a spring border. Planting several bulbs together creates a dramatic display, while individual plants can be used as architectural accents amongst tulips, narcissi and other spring-flowering plants.
How to Plant Fritillaria imperialis Bulbs
Plant the large bulbs in autumn at approximately 15-20cm deep, allowing around 20-30cm between bulbs. Crown Imperial bulbs have a natural hollow or depression in their centre. Planting them slightly on their side can help prevent excess moisture from collecting in this hollow during wet weather.
Improve heavy soils with grit and organic matter before planting to provide good drainage. Once planted, the bulbs are generally best left undisturbed so they can establish and return each spring.
Height and Spread
Fritillaria imperialis 'Aureomarginata' grows approximately 60-90cm tall with a spread of around 20-30cm. Its upright habit means it provides considerable height without occupying a large amount of border space.
After Flowering
Once flowering has finished, leave the stems and foliage in place until they have yellowed and died back naturally. This allows the leaves to continue feeding the bulb and helps build up energy for the following year's display.
The plant then becomes dormant below ground during summer. Avoid excessive watering around dormant bulbs, particularly in soils that are naturally heavy or slow to drain.
