The Cambridge Scarlet Monarda puts on a splendid display in the middle border in early summer. Its bright red blooms are particularly attractive to hummingbirds. Two objections are frequently raised with respect to this cultivar. First, it is a bit thuggish. I have successfully controlled it into an area with a plastic barrier. Any runners that do escape are easily dealt with by my soil knife. Second, it is susceptible to powdery mildew. Until recently I had no solution for this. Then I discovered Neem Oil Spray. Early and frequently application has eliminated powdery mildew for me. With its beauty and ability to attract hummers, Cambridge Scarlet is a welcome addition to my border.

I planted 4 of these in a 6' diameter bed and they practically took over. apparently S. Indiana really agrees with them. I love the bees and hummingbirds that are drawn to them and the rest of the garden.

I planted mine as 5 little plants I bought off of someone on Craigslist back in 2008 and they spread like wild fire and are growing great as of 2011. My plants do get up to 4 feet tall and sometimes a little taller. I do dead head cutting about 8 inches down from the flower heads after the first set of blooms which are big and bright start fading and I get a second bloom. I have read some cut them down to the ground but I figured in my area it is not a long growing season and may never see the second blooms appear. The flowers on the second bloom are smaller then the first set but still look good. This spring I took a shovel back in April and sliced under the plants like you would kinda do for sod when they were about 2inches tall and moved some to different areas. When I planted them in t... read more

In Missouri, I grew this at our previous house in full afternoon sun and it spread like crazy. Easy to grow--I started mine (5) from bare-root mail-order plants that looked like dried twigs, but they all grew. I didn't realize that all you need is one to get started because they will spread quickly (as in possibly too quickly). The blooms were incredibly gorgeous, but the plants bloomed for a short time only and then the stems looked awful. A heavy rain would also topple the stems, even when blooming. So the plants looked great for a couple weeks in summer and terrible the rest of the year. If I grow them again, it will be at the back of the yard where they have room to spread and will provide a nice spot of color when seen from the house. I didn't deadhead, they might have bloomed ... read more

I love the bee balm family. They produce some very striking and unusual flowers. It seems to thrive in Virginia's clay soil, but they do tend to be agressive growers. Mine are planted in a mass of Shasta Dasies, Black Eyed Susans and a False Sunflower. This is a rough neighborhood in which to grow, but their holding their own. They do seem to appreciate being out of full sun.

The flowers are striking, but the foliage is prone to mildew and it spreads about 12" out in each direction each year. At least the roots are shallow and it's easy to pull. Definitely needs to be planted behind 3' tall plants that will hide the mildew and legginess. Thrives in clay soil and dappled shade.
