What plants look good with alliums?

In addition to the mentioned plants, alliums also showcase their beauty when paired with ornamental grasses and salvias. The tall, architectural form of alliums complements the fine texture and graceful movement of grasses, such as Panicum virgatum (Switchgrass) or Pennisetum (Fountain Grass). Meanwhile, the vibrant shades of salvias provide a striking contrast to the delicate blooms of alliums, creating an eye-catching display in the garden.

How do I arrange alliums in my garden?

To arrange alliums in your garden, it is important to consider the size of the bulbs. For small allium bulbs, they can be scattered into wide and shallow holes, with a spacing of around 5cm. This scattering technique creates a beautiful and natural-looking cluster of alliums, adding a vibrant touch to your garden. On the other hand, for large allium bulbs, it is recommended to plant them individually, allowing for a spacing of about twice the bulb’s width between each plant. This method ensures that each allium has ample space to grow and showcase its unique beauty, creating an organized and visually appealing arrangement in your garden.

What can I plant with allium bulbs in pots?

One great option for planting with allium bulbs in pots is to combine them with colorful tulips. Tulips also bloom in spring and come in a wide range of vibrant hues, making them a perfect complement to alliums. Additionally, consider adding other spring-blooming plants like daisies or pansies for a diverse and captivating display in your containers. These additions will further contribute to extending the period of interest and create an eye-catching arrangement of flowers in your pots.

How many allium bulbs should I plant together?

To achieve a more naturalistic display with smaller allium bulbs, it is recommended to plant them 7-10cm apart. However, for taller species, it is best to space them around 20cm apart. It is important to note that if the soil is already moist, watering them in may not be necessary.
