Allium Cristophii

Allium Cristophii – is also known as Star of Persia. The large metallic silver-lilac heads reach up to 20cm in diameter. They are made up of many tiny star shaped flowers on long stems. Unlike many alliums, the flowers are not as tightly packed. The large stars make a transparent frame work for a truly unique focal part in the garden bed.

The foliage is large and broad, it begins to die back once the the flowers appear. Fortunately, it stays out of sight under the long stem of the flower which reaches to 60cm tall. They begin to flower in late May-June and fill the gap between spring and summer. Try pairing with Camassia or Gladiolus Byzantinus.

Allium Cristophii continues to look extremely intriguing when the seed heads are dried.

Allium bulbs are related to onions, shallots and garlic and sometimes referred to as Ornamental Onions. They are hardy and easy to grow, with tall elegant stems that don’t overcrowd an area, making them a versatile addition to any garden.

Where do I plant Allium bulbs?

Allium bulbs are remarkably tough, drought-resistant, they grow best in full sun in borders. They can be clumped together for blocks of colour, mixed in with other plants and flowers to add depth and texture.

Plant in mid-Autumn in well-composted, free-draining soil that is slightly acidic. Plant Allium Cristophii bulbs 15cm deep and 20cm apart (at least). Water regularly during dry spells but take care not to over-water as this may cause the bulbs to rot.

Avoid planting allium bulbs in areas that are regularly cultivated as it is easy to damage them when digging.

Alliums are quite easy to grow. Plant them in well draining soil, they don’t like to be soaked. Keep them moist once they start to emerge. Plant the bulbs 15cm deep and 20cm apart (at least). They need to be in a sunny position.

How do I look after Alliums?

After flowering, you can remove the deadheads, but you don’t have to as they still look attractive. Leave as many leaves as possible to produce food for the bulb for the following season. You can lift allium bulbs if you choose, but you don’t have to, they are hardy and don’t need any special care over winter. Alliums are fairly slow to multiply, any offset bulbs should be replanted immediately, although it may take a couple of years for these to mature enough to flower.
