To say that blue passionflower is a vigorous vine is a huge understatement, and the flower production is also very impressive. The blue passionflower is known botanically as Passiflora caerulea and is cold hardy over the entire state.

Ogon, the leading variety of Japanese sweet flag, is just beginning to attain all the wonderful landscape possibilities that it is capable of achieving. This year has given me a new appreciation for this member of the lily family.

Dwarf sweet flag, mostly called Japanese sweet flag, is known botanically as Acorus gramineus. Although still fairly new in our local markets, this grass is drawing increased attention.

No matter where you go in the South right now, the plant that seems to be in a constant state of standout performance is the alternanthera, or Joseph's Coat.

Of course, most of the Joseph's Coats we see are the lime green selections usually partnered with coleus or cannas. They are doing quite well at my house even though there is a baby cottontail trimming them for me nightly.

Mississippi is a long way from Hawaii, but we still can enjoy a special Hawaiian flower in our landscapes.

Most people are familiar with the tradition of giving floral necklaces called leis to visitors to Hawaii. The flower used most commonly is a plumeria, also called frangipani. The plumeria has a tantalizing fragrance and commands attention whether grown in a container or the landscape. Once you start growing it, you will become hooked.

No matter where you go this summer the tropical look is hot, and one of the key ingredients to this Caribbean-style garden is the elephant ear.

With leaves that defy logic in size and proportion to other plants, it's not hard to see why this plant is so loved by Southern gardeners. It is not uncommon to see 6-foot-tall plants with 3-foot leaves on petioles reaching 4 feet.

This time of the year, we start heading for the shady part of the garden where it is lush and cool. We think of impatiens, begonias, hostas and caladiums for seasonal color in this area, but there is another plant that needs to be in many more gardens, and that is the crossandra.

Pay attention as you're scurrying about this early summer and you will notice one of our finest shrubs blooming and attracting butterflies by the scores. The buddleia's fragrant blossoms attract butterflies and look great as cut flowers. It is referred to as butterfly bush in the United States, and summer lilac in its native China.

As the weather heats up and sends us indoors to a cooler environment, salvias really start to show their beauty in the landscape. One that every gardener needs is the pineapple sage.

Not too many plants can look equally at home in a tropical garden and an old-fashioned cottage garden, but such is the virtue of the Texas Star hibiscus. This hibiscus, known botanically as Hibiscus coccineus, also is known by less enticing names like swamp mallow or scarlet mallow.

My neighbor down the street already has everyone gawking with a spectacular Mandevilla on her mailbox. It's been that way for a few weeks, yielding dozens of blooms every day.

Many gardeners shop for plants that will bloom all summer and right up until fall. That's a pretty tall order to fill considering our extreme summer climate, but at the top of that list has to be the hybrid Mandevilla Alice du Pont.

Garden centers have had a good supply of one of my favorite plants, the gomphrena. Known botanically as Gomphrena globosa, this Joseph's Coat relative is native to Panama and Guatemala.

At the Jackson Garden and Patio Show, a new group of hibiscus made its debut and wowed everyone. Called Cajun hibiscus, this series comes in colors you only dreamed about. I got two at the show -- one called Black Dragon that is a deep burgundy with swirls, and then a yellow and red blend called Fais Do Do. Both are extremely large, measuring 9 inches at least.

The future looks bright for pentas, one of our best groups of annuals. I've just returned from the California Pack Trials, and almost every company is introducing new series. This should be a delight to butterflies, hummingbirds and gardeners alike.

Ask gardeners why they start growing roses, and you'll get a range of answers that usually fall into a couple of categories. Many will say that they began a rose garden because the queen of flowers provides such beauty, while others love the fragrance.

If you feel like spring is racing by and you haven't planted anything, don't fret. Today's annuals can give flowerbeds the pick-me-up you need. No other group of plants provides as much color as quickly and economically as annuals.

Prepare beds by adding 3 to 4 inches or organic matter such as compost, humus, pine bark or peat moss, and 1 or 2 inches of sharp sand if the soil is really heavy.

One plant that seems to have caught on in a big way with gardeners is the calibrachoa. This petunia-like flower arrived only a few years ago, and now there are more varieties than I can keep up with. Million Bells was first, then came Colorburst and Liracashowers, then Calle and Starlettes, and now there are Superbells, MiniFamous and Cabaret, plus others.

The word "plectranthus" sounds like it could be some dinosaur that's been discovered in a South Mississippi gravel pit, but believe it or not, a variety named Mona lavender is a 2005 Mississippi Medallion Award winner.

Mona lavender, which is one of the hottest plants in the world, has passed muster in Mississippi State University trials and was chosen by the Mississippi Plant Selections Committee for this prestigious award.

"Beautiful," "striking" and "tough-as-nails" are just a few of the adjectives horticulturists use to describe Purple Knight alternanthera, which just received the 2005 Mississippi Medallion Award. Purple Knight is guaranteed to take gardening to new levels of enjoyment.

An old favorite just got better -- and larger -- with the new Titan series, prompting some to reconsider periwinkles for the garden. Last year they made their local debut at the Mid-South Greenhouse Growers conference held in Raymond, and growers from several states were mesmerized.
