This time of the year is again the right time to plan a colorful display of flowers for next spring. If your garden failed to impress last spring, you can lay the groundwork for a more satisfying experience in the spring of 2019.
The early fall is the time to plant spring-blooming bulbs. A good selection of such bulbs will become available around mid-August to early September in local garden centers and from mail-order nurseries. Two categories of bulbs will be in the greatest demand and likely to be snapped up while some gardeners are just beginning to plan. These two categories are (a) the most popular and (b) the more unusual.
For a list of the most popular spring-blooming bulbs, visit the National Gardening Association’s website, garden.org and search for “The Top 50 Most Popular Spring-Blooming Bulbs.“ You will not be surprised to find several varieties of tulips and daffodils at the top of this list.
To learn about the more unusual spring bloomers, visit the website for Brent & Becky’s Bulbs, click on “Media” and open the file “Spring Flowering Bulbs Cultural Instructions.” This downloadable free publication includes both a long list of spring bloomers and detailed instructions for growing these plants, with particular information for the cultivation of tulips and daffodils.
Another good source of information for both popular and unusual spring bulbs, visit McClure & Zimmerman.
My garden includes a good number of daffodils (all the same cultivar) that I enjoy each year, but the more unusual bulbs are most appealing. This year, I am learning about fritillaria, a genus in the lily family, with about 140 species. The most popular is F. imperialis, called “The Crown imperial,” which is native to countries of the eastern Mediterranean region, e.g., Turkey, Iran, and Iraq. The plant grows over three feet tall and is available in several varieties that have blossoms of different colors. It grows best in full sun, in zones 4–7. The Monterey Bay area is in zone 9, so F. imperialis might be a risky choice for growing here.
A better choice for this area would be F. meleagris, called the Checkered Lily, “Snake’s Head Fritillary,” or “Guinea-Hen Flower.” This plant, which is native to Europe, will grow in sun or partial shade, in zones 3–8, so our local zone 9 environments might be “good enough” for this plant. It will reach to only fifteen inches tall, so it’s not as striking as F. imperialis.
Another important group of spring bloomers that the bulb catalogs do not offer is the irises. That must be because irises grow from rhizomes rather than bulbs, and are offered by specialty growers rather than bulb growers.
I call attention to irises because I have a long association with the Monterey Bay Iris Society, which is preparing its annual rhizome sales. The first sale will occur on Saturday, August 4th at the Deer Park Shopping Center in Rio del Mar. The second sale will be on Saturday, August 11th at the Aptos Farmer’s Market, at Cabrillo College, Aptos. These sales are excellent opportunities to acquire iris rhizomes at good prices and to receive good advice from local enthusiastic gardeners.
If you already have irises in your garden, they should be dug and divided every three or four years for maximum blooms. I call attention to this task because my own irises are overdue for dividing!
Whether you prefer popular or uncommon spring bloomers, preparing for a delightful spring garden happens during the next few weeks. To begin, identify space in your garden where you could plant spring-blooming bulbs, then acquire the bulbs (or rhizomes) of your preference at local garden centers, mail order nurseries, or the local sale of iris rhizomes.
