    It is a super easy-to-grow plant and its superb silvery purple flowers will fit into absolutely every plant collection in little to no time.

    If the Star of Persia stole your heart from the very first glance, you must wait for the autumn to come before adding it to your garden. This plant shows up in garden stores only at the end of this season, as it goes dormant during the summer and autumn months. You might also want to look for the Allium albopilosum since some shops still sell it under this name.

    • Like most bulb plants, the Star of Persia is pretty toxic to animals.

    When it goes dormant, usually in summer and autumn, the Star of Persia will appreciate a general dry period. Because of this, it would be wise to keep it indoors if you live in an area with frequent rainfalls during its dormant season.

    In terms of pest infestations and fungal diseases, luckily, you will not encounter serious problems with your Star of Persia. Even if this plant can get a few diseases like rot or downy mildew, you can easily prevent them from occurring.

    All you need to do is avoid watering your Star of Persia from above as the water remaining on them can help diseases to show up. And in case an infection has already appeared on your plant, you should remove the infected bulbs right away.

    Some intruders that might visit your Star of Persia include slugs, snails, and leaf miners. However, these pests do not particularly affect the leaves of this plant so badly. The foliage of Star of Persia does not generally last very long, so a bit of damage on it should not worry you too much.


    Planting Star of Persia

    Without a doubt, the ideal time to plant your Star of Persia is in autumn when it typically ends its dormant period. This is the season when you will most likely find Star of Persia, and its close relative Ornamental Onion, and other type of bulb plants in garden shops, nurseries, or markets, so you should look for them if you have fallen in love with this beauty.

    The Allium cristophii bulbs should be planted fairly deeply because this plant does not like to compete with other plants. Most members of this genus are intolerant of competition from other growing plants.

    A very interesting feature of the Star of Persia is its ability to grow in absolutely any type of soil. Keep in mind, though, that it will do so only if the substrate comes along with excellent drainage. Besides the well-draining characteristic, the Star of Persia also prefers a soil pH that is more on the acidic side, with values around 5.5 to 6.5.

    If your garden soil does not have very good drainage, you can add a generous amount of organic matter to it before planting your Star of Persia. Likewise, the organic matter will ensure enough water reaches the bulb.

    In case you opt for amending the soil with organic matter regularly, you can skip fertilizing your Star of Persia for good. But if not and you grow this plant in poor soil, a touch of fertilizer might be more than helpful for it. Once it begins to set flowers, feed your Star of Persia with an all-purpose balanced fertilizer. This yearly application will give your plant enough energy to use for blooming.

    When the flowering period of your Star of Persia has ended, pruning would be more than welcome in its caring routine. In other words, trimming the flower stalks down when the time is right will move the plant’s focus to store its energy in the bulb.

    This process is beneficial for your plant but is not mandatory. Some gardeners choose to leave the dried flower heads where they are and enjoy their splendour on the plant for as long as they stay on it.

    Watering Star of Persia

    By now, you might have noticed that the Star of Persia rewards gardeners with its super low-demanding nature. But wait to see how perfect this plant is thanks to its minimal requirements when it comes to watering!

    If you live in a location with regular rainfalls, you can even forget that this plant exists in your garden, as it will get the needed moisture from Mother Nature. What can be more satisfying and easy-going than this?

    In general, the Star of Persia does well with infrequent watering. It does not really matter how often you water this plant as long as its soil remains damp to the touch. Some gardeners prefer to water their Star of Persia plants once every three to five days.

    Still, the frequency of watering might be different for you depending on the weather and other growing conditions.


    Propagating Star of Persia

    The Star of Persia emerges from bulbs that can make for a wonderful propagation material if you want to obtain more specimens. This plant is worth all the time and tiny effort you put in growing and caring for it and it is only natural to dream of a garden full of it.

    And if some of your family members or friends have seen your Star of Persia and still have it in their minds, even better! You can make a few for them and ease their minds in just a few steps.

    The best time to propagate your Star of Persia is in autumn, as this is also the suggested time to plant the bulbs. Before getting into action, you must know that this bulb-growing plant multiplies relatively slowly. But once your plant begins to form small offsets on its bulb, nothing can stop you!

    When the Star of Persia has ended its blooming season, you can lift the bulbs and remove the tiny offsets from it. After this, replant the offsets immediately wherever you want. The depth of planting must be two to three times the diameter of each bulb in particular.

    Make sure you water the offsets well after you plant them and cross your fingers until the next spring. And promise us you will not get sad when you see that the new specimens do not produce any flowers. It may take a couple of years before the young Star of Persia plants bloom.

    In Conclusion

    If your garden is lacking a dash of purple and you have absolutely no idea what plant to add to it next, the Star of Persia can be the perfect candidate for it. The fabulous appearance of this plant mixed with its almost independent nature can turn it into one of your favourite ornamental companions out there.

    You can grow it alongside many different flowering plants and even in your vegetable garden (just not near legumes) and you can also grow it in your cutting garden. Allium cristophii, commonly known as Star of Persia, will easily self-propagate through bulbs and will return to your garden every spring if the environmental conditions are good. If you make this versatile ornamental onion a member of your plant family, your garden will surely be more full of life!
