October is spring bulb planting time. While the tulips, daffodils, and crocus head the list of popular bulbs to plant later this month, don't forget some of the more unusual bulbs such as the alliums.

Allium or flowering onion plants range in sizes from 5 inches to 4 feet tall. The tall varieties make a statement in the garden rising about the foliage of perennials such as daylilies. The smaller growing bulbs are great in front of the border or as rock garden plants. Alliums are trouble free. They come back consistently each year and deer, rabbit and mice don't seem to bother the bulbs or flowers. Many bloom in late spring and early summer after the daffodils and tulips finish.

For a big flower show nothing beats the tall, large, purple flowered types such as 'Gladiator'. A large white flowered version is 'Mount Everest'. 'Purple Sensation' is a little shorter and smaller flowered, but it multiplies readily over time. Some shorter alliums add more color. The drumstick alliums have red and green colored blooms. Allium caeruleum has blue colored flowers and Allium moly is a short, yellow flowered type.

Whatever varieties you choose, plant later this month in a full sun location on well-drained soil. Plant in groups or pop some of the tall, large flowered types in among the perennials for a surprise effect. After they're finished blooming consider leaving the seed heads. They're interesting to look at and add a different texture to your plantings. You can cut them for use as indoor flower arrangements.
