Feverfew (Tanacetum parthenium) is an old herb once thought to treat fevers but actually is helpful in preventing migraine headaches. I first saw the plant blooming at a demonstration garden a few years ago and liked the small, daisy-like flowers, similar to chamomile. I sowed seed late last summer and transplanted the seedlings in the ground before frost. They weathered the mild winter in my zone 7 Virginia garden but remained small. When the temperature increased in early spring, the plants grew up very fast and started blooming as early as . The plants are several feet tall now in full sun, oblivious to our current dry spell. I do not use feverfew medicinally but as a summer flowering perennial. Because they are small white flowers, they are great by themselves in a vase or as a filler with other flowers.
I read that the plant has a strong and bitter smell but I don’t notice it. I have also read that feverfew has mosquito repelling qualities but there are still the same number of mosquitoes in my garden. However, I have noticed that nothing goes near it, no deer and no rabbits.
My variety is Heirloom Double White Wonder from Renees Garden but there are other cultivars on the market such as Aureum, White Bonnet, Golden Ball, Crown White, and Ultra Double White. You may not find this in your local nursery as a plant; you may have to purchase seed but the seed germinates easily. Feverfew is known to be a short-lived perennial but it will be a summer-long success in my garden this year.
The 15th of the month is Garden Bloggers Bloom Day where garden bloggers post photos of plants that are blooming in their area across the country.
I forgot to grow zinnias. Every year I grow zinnias so I can put a vase of flowers on my desk at work but for some odd reason, I didn’t this year. Now in the heat of summer I don’t have many options to choose from but next year I will grow zinnias for summer blooms and on top of that, will start even earlier with spring flowers.
To learn more about increasing the diversity of flowers in my Northern Virginia garden, I have been following Lisa Mason Ziegler’s virtual book study for the past month. Each Friday for 10 Fridays, she posts a 10-minute video that corresponds to a chapter in her book, Cool Flowers: How to Grow and Enjoy Long-Blooming Hardy Annual Flowers Using Cool Weather Techniques. The videos can be viewed on her website any time and she is more than happy to answer questions. Lisa manages a commercial cut flower business in Newport News, Virginia. She is well known in the horticulture field, has written books and given lectures, and has an online garden shop called The Gardener’s Workshop. Lisa is an expert on hardy annuals, which prefer to bloom during spring’s cool temperatures. Hardy annuals differ from the summer annuals in that the seeds are sown in August/September or February/March, depending on the plant. In contrast, summer annuals, like zinnias, prefer the heat so they are sown after the danger of frost has passed in late April/early May.
Of the 30 plants mentioned in her book, I have seeds of six plants on hand. I can start snapdragon, dianthus, and feverfew indoors now and transplant at the end of August. I can direct sow love-in-a-mist, larkspur, and calendula seeds at the end of August to the beginning of September. All of these will bloom in the spring and peter out when summer arrives which will increase my number of cut flowers from spring to early summer. From then on the summer annuals can take over and I will look for a few more in addition to zinnias. In her videos and in her book, Lisa discusses her preference for direct sown versus transplants and starting in the fall versus early spring. If the plant is hardy to a zone colder than one’s own zone, plant in the fall. If the plant is not has hardy as one’s own zone, plant in early spring. However, early spring can mean cold, wet soil so she suggests preparing the bed in the fall and covering with mulch or landscape fabric to prevent weeds and to enable the ground to be worked easily in February and March.
So far I have viewed 5 of the 10 videos and I have read the book. If hardy annuals are something you would like to try, you can catch up by visiting her web site and listening to her videos or buy her book on her site or at a bookstore but it is not necessary to have the book in order to follow along with her videos.
