When grown in urban settings Carex eburnean can be used to fill spaces where most plants fail – under shady trees, lands that are not frequently irrigated, and soil that is too sandy to grow your favorite plants.

Alliums: The Ornamental Onions

Alliums, commonly known as Ornamental Onions, are popular perennials among gardeners because of their graceful flowers and ability to grow in many different conditions. Most Alliums are characterized by their tall flower stalks (up to 3 feet) that stand like sentries with big, round flower heads (up to 5 inches). Their prominent flower heads make Alliums very useful for providing a nice and attractive background to low-growing bloomers in flower beds.

Growing Alliums should not be a big challenge even for beginners. They are drought-tolerant, resistant to pests, and low on maintenance. They also come in a wide range of variety in terms of heights, blooming period, and form and color of flowers. Alliums are grown from bulbs planted in the fall. Bulbs should be planted at a depth of four times the diameters of bulb. Alliums generally prefer a rich and well-drained soil under sunny conditions. If you are growing them in poor soil, feed them with a general fertilizer in early spring or top up the soil with a layer of compost [Also read: How to prepare your own compost].

Most varieties start blooming from late summer to early summer. Flowers, especially of late blooming verities, last longer. Both fresh and dry flowers make excellent addition to flower arrangements. As end of season approaches, leaves start straggling and should be cut back, if required. Once flowering is over, bulbs can be lifted and stored for the next harvest.

Popular varieties of Allium include:

Allium ‘Purple Sensation’ produces large (3 inches or more) purple flowers on tall (up to 3 feet) stalks.
