A Landscape Combo for Native Fall Color: Muhly Grass & Darrow’s Blueberry
In the Panhandle, fall is the prettiest season for wildflowers. Our roadsides and woodlands are covered with pinks, whites, yellows, blues, purples, and even a little red here and there. Pretty as it may be, the beautiful wildflower look isn’t super appropriate for most yards. It would look unkempt, a little “wild” if you will, would be hard to manage and is probably best enjoyed in natural areas. However, we can bring some of the native colors of fall into our landscapes in a much lower maintenance, refined manner with two Panhandle species that pair excellently together, Muhly Grass (Muhlenbergia capillaris) and Darrow’s Blueberry (Vaccineum darrowii).

Muhly Grass, the native grass with the pinkish/purple panicles blooming right now, has gained much popularity in recent years, earning a reputation as a near pest/disease free, drought tolerant, attractive landscape plant. Operating in lieu of more traditional low growing shrubs in landscapes, Muhly is an airy, greenish gray bunch grass growing about 3-4’ tall and wide, lending informal, coastal texture to landscapes most of the year and really shining in fall during its flowering season. Once established, it never needs extra water, prefers little fertilizer, and only needs a rejuvenation prune (or burn – the Leonard preferred method. It’s fun and mimics the role of fire in Muhly’s native ecosystems!) every couple of years to keep it looking tidy.
Unlike Muhly Grass, Darrow’s Blueberry has not caught on broadly in the landscape industry but is no less deserving. This native blueberry species only grows a couple of feet tall, produces edible fruit that wildlife enjoy, and adds an unusual blue green color to landscapes via its tiny-leaved, evergreen foliage. It prefers the same sites as Muhly and is part of the reason they pair so well together. Our mostly sandy, well drained soils work just fine, but both plants can handle soils that are occasionally wet. A bonus, Darrow’s also has tiny, bell shaped flowers in spring that attract all manner of beneficial bee species. This makes it a must in any native pollinator garden!
As good as these species are alone, I think they are better together. In my family’s yard, we created a loose screen of widely spaced (8’ apart) Muhly Grass specimens around a pool, in the spirit of giving the area a “coastal” airy feel, and interspersed Darrow’s Blueberry in between.

The look has been outstanding, particularly in the late summer/early fall. The pinky purple flowers of Muhly Grass complement the green-blue foliage of the blueberries nicely and provide easy, lasting color without having to worry about planting finicky annuals or perennials each season.
Landscaping with natives does not have to look wild and unkempt, nor does it have to be drab and unattractive. Combining native yet showy plants like Darrow’s Blueberry and Muhly Grass makes for an unusual, refined, nearly no-maintenance feature in your landscape. Look for these and other neat native plants at native nurseries and independent garden centers around the Panhandle. If you’d like more information on native grasses, blueberries or any other horticultural topic, please contact your local UF/IFAS County Extension Office! Happy Gardening!
Try Chinese Pistache for a Small Tree Selection
Many people often request a recommendation for a small tree that will be suitable for their landscape and one to consider is the Chinese Pistache, Pistachia chinensis. Although not a native tree, Chinese Pistache does not have invasive potential so it can make a suitable option for both commercial and residential landscapes.

The best features of Chinese Pistache are the fall color it offers with orange leaves, followed by clusters of salmon berries. It will lose its leaves as days shorten but you can enjoy the textured bark during the winter season. Compound leaves offer interest as well during the spring and summer. Adding some medium to fine textured foliage plants under and around trees will provide a nice landscape display.

A positive feature of Chinese Pistache is that once it is established, it is tolerant of drought. Expect trees to be about 25 to 30 feet in height with a 20 to 25 foot spread. Each tree will have it own unique branch structure and some pruning will be required when trees are young to develop strong connections. You may plant as a full sun tree to provide a little dappled shade for your garden or use as an understory tree in partial shade.
Are We Creating Super Bugs?
Normally, you will have one of four answers: “yes”, “no”, “I don’t know” or “what are super bugs?” The answer to the last one is an insect or other pest that has become resistant to chemical treatments through either natural selection (genetics) or an adaptive behavioral trait.
The next question is do you treat insect or pest problems at home with a purchased EPA registered chemical (one purchased from the nursery or other retailer)? If you answered yes, then the next question is how many times in a row do you apply the same chemical? If you only use one chemical until the product is used up, then you might be creating super bugs. Do you ever alternate chemicals and if you answer yes, do you understand chemical Modes of Action (how the pesticide kills the pest)? If you do not, then chances are the rotating chemicals might act in the same way. Thus, you are creating super bugs because in essence you are applying the same chemical with different labels.

One of the first ways to reduce creating super bugs is to practice Integrated Pest Management (IPM). The very last step of an IPM philosophy is chemical control. You should choose the least toxic (chemical strength is categorized by signal words on the label: caution, warning, and danger) and most selective product. A chemical label advertising it kills many pests is an example of a non-selective chemical. You want to choose a chemical that kills your pest or only a few others. In Extension education, you will always hear the phrase “The label is the law.” To correctly purchase a chemical, you must first correctly identify the pest and secondly the plant you want to treat. If you need help from Extension for either of these, please contact us. Before purchasing the chemical, always read the whole label. You can find the label information online in larger print versus reading the small print on the container.

You now have the correct chemical to treat your pest. Wear the recommended personal protective equipment (PPE) and apply according to directions. If your situation is normal, the problem is not completely solved after one treatment. You might apply a second or third time and yet you still have a pest problem. The diagram explains why you still have pests or more accurately super bugs.
Now the last question is how do we really solve the problem given that chemicals are still the only treatment option? A bit more work will greatly help the situation. You need to download the Insecticide Resistance Action Committee (IRAC) guide and find the active ingredient on your chemical label (http://edis.ifas.ufl.edu/pi121 or https://irac-online.org/modes-of-action/ and select the pdf). If you are like me, you can just download the IRAC MoA smartphone app and type in the active ingredient; otherwise, Appendix 5 in the pdf has a quick reference guide. Either way, you will know the Group and/or Subgroup. A lot of commonly purchased residential chemicals fall within 1A, 1B or 3. The successful treatment option is to select chemicals from different group numbers and use them in rotation. If you start practicing this simple strategy, your treatment should be more successful. Then when someone asks if you are creating super bugs, your answer will be no.
If you have any questions about rotating your chemical Modes of Action, please contact me or your local county Extension agent.
