Q. Who is Mr. Smarty Plants?

A: There are those who suspect Wildflower Center volunteers are the culpable and capable culprits. Yet, others think staff members play some, albeit small, role. You can torture us with your plant questions, but we will never reveal the Green Guru's secret identity.

Title: When to plant wildflower spring mix seeds in Ashburn VA
Answered by: Barbara Medford

QUESTION:

I just bought wildflower springmix and want to know when to plant them, is there a specific temperature?

ANSWER:

We are always a little leery of wildflower "mixes." They are heavily marketed as being the way to have lovely blooming meadows with just a sprinkling of seeds. The Lady Bird Johnson Wildflower Center is dedicated to the growth, propagation and protection of plants native not only to North America but to the area in which they are being grown. Without knowing what seeds you have, we can only guess that the right time to plant them is now, in early Spring. Were there any planting instructions or plant names on the package that you purchased? In Central Texas, we plant our seeds mostly in the late Fall, because our ground doesn't freeze and most of our native wildflowers will start putting out rosettes of leaves in December to January, and are blooming right now, in mid-March. Your weather is probably enough colder that the seeds wouldn't stand a very good chance being planted in the Fall, but you surely want them in the ground to benefit from Spring rains and to protect the new little plants from heat.

Another warning about seed mixes - they may include not only seeds not native to your area or to any of North America but also invasive weeds. We are going to send you to a couple of our How-To Articles to give you some idea of the importance of using natives. The first is Using Native Plants and the second is Meadow Gardening. You will learn that wildflowers don't fit into a category that can be easily put in a mix. And, finally, when you get a nice stand of native wildflowers, you might want to consider Seed Collecting and Storage.
