Say hello to my blue annual salvia, sometimes called flowering sage. Supposedly a plant that cannot tolerate our colder winter, I was told it would grow one season. It is on it's third season. Some plants are like that, they fool ya. This plant, to you more southern dwellers is actually a perennial in Texas and Mexico, and apparently in some Northern Oklahoma gardens too.
Which brings me to a few definitions. Let's see if you get these right. I'll post the correct answers tomorrow.
An annual is:
a. a plant that comes back every year
b. a plant that is hardy
c. a plant that grows and blooms in one year then dies
d. that pesky dr's appointment you go to every year
A perennial is:
a. a plant that re-seeds itself every year
b. a plant who's roots stay alive all year even if the foliage dies back in winter
c. a weed and should be removed before it takes over the garden
d. a word you should not use in public
When referring to plants as hardy, this means:
a. the coldest temperature to which a plant can survive
b. the hottest temperature to which it survives
c. Plants that do not need much water or care
d. Plants that have really woody stems and are hard to cut
Be sure and read tomorrow to see if you got the answers right! You win absolutely nuttin' but the pat you give yourself on the back for tryin'!

And here is a welcome steady bloomer in my garden... Coreopsis. This perennial plant can be a real show stopper. It can also be prone to white powdery mildew, which seldom kills the plant but looks awful, and retards blooming and growth. With all the rain we've had, I'm surprised these are not covered in it, but Jeff, the gardening angel has been spraying it. Which brings me to another quiz. Okay you guys, you are not actually being graded. Relax.
See if you can match the definition to the right word.
Definitions:
a. a substance that kills insects on contact, even the good ones
b. a substance that gets into the plant and kills insects when they eat it
c. a subtance that kills plant diseases that come from spores
d. a substance that kills weeds and sometimes other plants
Now match the right definition to the right word below:
1. a fungicide
2. a pesticide
3. an herbicide
4. a systemic pesticide

And while you are thinking on that, let me confuse you further. These coreopsis, while perennials, self sow. That means they reproduce and spread by dropping seeds. If you want to control the spread, you can dead-head the blooms, or you can use a seed retardant like Preen®, or you can thin the seedlings out while they are young. Now some of you are die-hard organic gardeners and I get that. I myself would rather pick a weed than spray it. My master gardener friends tell me, as does the label, that Preen® is actually an organic substance, so I think you are okay to use it. But I'd read the label to be sure before using it around edible plants. And be aware that if you like to sow packets of flower seeds in the garden, do not use Preen® in the areas where you intend to sow. Those seeds will not germinate either.

And that concludes this teaching moment from Dana's Garden. Don't forget to compare your answers tomorrow! Now go plant something and watch it grow!
