Pansies and their cousins violas are still going to be the most popular annuals in Texas landscapes month in and month out. But that doesn’t mean that they’re your only options for mid-winter color. I’m going to put a few other possibilities in the spotlight over the next several weeks here, and I’ll start with a couple of unusual ones this time.

Cardoon leaves are showy in their own right, not to mention the plants’ tall, upright habit.

This plant looks like a big gray-green thistle growing to 3 to 4 feet tall. It’s botanically Cynara cardunculus, and it’s from the Mediterranean area where the cool summers and mild winters are perfect for its perennial lifestyle.

Because our Texas summers are so hot we grow it as a winter annual for the drama of its foliage and its unusual habit of growth. Use it as a backdrop to other annuals, or plant it as the “thriller” in the center of very large patio pots or patio beds. Its flowers are violet-purple, thistle-like blooms and they’re really quite showy.

Every garden deserves a few cardoons.

Ornamental kales have become very popular, but most form showy heads. Redbor is different. It is an upright, leafy selection that is being used more and more often.

Redbor kale…

Redbor kale is another tall plant for the back of the annual bed or the center of a patio pot. It differs from our common heading ornamental kales in that grows upright with loose leaves, maturing at 18 to 30 inches before it bolts into flower by late spring.

And, if you’re willing to part with a few leaves all along, this one is absolutely loaded with nutrients. It’s great mixed into salads. Don’t use the newest leaves, and certainly don’t harvest the bottom ones, either.

Once the plants have bolted into bloom by mid- to late spring it’s time to take them out.
