Tought to tell at that size. Might be a Cavendish variety. Could even be one names "Valery", which is a pretty good performer, for a short banana. See http://webebananas.com/bvar-T-Z.html

Heather is the common name for Calluna vulgaris, nearly all of which are late summer into fall (sometimes later) bloomers. Heath is the common name for Erica species, many of which have late winter into spring blooms with Erica cinerea blooming summer to early fall. Not sure how they are presented where you are, but nurseries in this area offer them when they are in their bloom season, the exception being those that offer seasonal foliage color - a nonblooming heath or heather is unlikely to inspire any impulse buying, most being a rather undistinguished green lump. Most of what should be on offer right now are the Ericas, so you can select by bloom color. Also look for Callunas with seasonal color, like 'Spring Torch', 'Moonglow', 'Ruby Slinger', 'Flamingo' or 'Arina', with new growth tips in shades of cream, yellow, pink and red - this can be almost as attractive and colorful as the flowers. In our zone 8 climate, you can plant them whenever you buy them.

Now that I've had a chance to take a closer look at the image and blow it up, what I initially thought might have been collapsed tissue is probably nothing more than water drops. Are you sure it's all the same plant in the last 3 pictures, #3 looks to be different from the first 2. Look on the Hosta Library for same examples of the different manifestations of HVX. You would like to think that a good specialty nursery in your area might be able to confirm whether a given specimen is HVX infected, but I wouldn't count on it. You're best off to look at as much information on the subject as you can find. Pieter

As PK pointed out, late spring through summer is not the best time to plant perennials, since the heat index maximizes transplantation shock. Big box garden centers rely on impulse buy to sell their plants, so their perennials will be available when they're in bloom, which is rarely the right time to plant them. Perennials planted in the fall after the temperature drops below blast furnace levels have a much easier time becoming established. Since Lowe's and HD don't carry visually drab rosettes, you'll want to visit a reputable mom & pop's nursery. The exceptions to fall planting are marginally hardy perennials that are best planted in early spring after the risk of frost has passed. As a rule of thumb, group plants by exposure, soil and irrigation. KO roses, hibiscus and exotic daisies perform best with full sun, improved soil and supplemental watering. Butterfly weed (not butterfly bush) and most salvias do well with full sun, native soil and local rainfall. Turk's cap and shrimp plant are ideal for full shade, native soil and local rainfall. Pigeonberry and rock rose prefer morning sun and afternoon shade; they'll look better with improved soil and even moisture, though neither is necessary. Once you've separated the perennials that need supplemental water from those that don't, you can route your drip line(s) accordingly; i.e., there's no need to waste irrigation water on tough customers like Salvia greggii, while hibiscus won't survive without it. Caveat: I've never lived in DFW, so take the above species with a grain of salt until someone from your area approves/disapproves them.
