Start Hardy Annuals now for Spring Flowers

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.
