| Gomphrena 'Cosmic Flare' from Plants Nouveau |
I am loving making bouquets this week with orange Dahlias, assorted Zinnias, and the Globe Amaranth (Gomphrena) 'Cosmic Flare'. The latter is taking over the cut-flower bed in the plot and has pretty much buried the Lisianthus, but I'm not mad -- it is such a doer and the lime foliage and pink pom-pom flowers are show-stoppers.
What a difference a week of rainy, cool weather makes! Compare the row of 'Mesclun Sweet Salad Mix' (the 3rd green stick/line in the photo above) to last week's: https://washingtongardener.blogspot.com/2026/09/fenton-friday-lettuce-seeds-up.html The Lettuce is edible at this stage, though we'll wait another couple of weeks to harvest and eat it. Meanwhile, the Cilantro and other seeds in this bed are being slow to germinate. If they are not up by next Tuesday, we'll likely replace them.
I picked more Okra, Cucamelons, Beans, and Tomatoes. I'll give them a few more weeks, before removing them.
I pulled the Squash plant and put Snow Peas in their spot along a back trellis. I'm debating on filling in underneath the Peas with a cover crop or perhaps some Radishes.
I haven't pulled the Basil plants yet, but will do so soon.
The Blackberry is throwing out big branches and is still setting fruits. I need to tame that and tie it back. It is thornless, so isn't scratching anyone -- but is still so rangy that it gets in the way.
I need to cut back the remaining Garlic Chives as they are going to seed and I definitely do NOT want any more in the plot or pathways! The Asparagus foliage will need cutting back soon too.
In the Pollinator Strip, the flowers on the Jerusalem Artichoke look about to open and some self-sewn Calendula are blooming under them now too.
What are you growing and harvesting in your garden this week?
About Fenton Friday: Every Friday during the growing season, I'll be giving you an update on my community garden plot at the Fenton Street Community Garden just across the street from my house in zone 7 Mid-Atlantic MD/DC border. I'm plot #16. It is a 10 ft x 20 ft space and this is our 15th year in the garden. (It opened in May 2011.) See past posts about our edible garden by putting "Fenton" into the Search box above (at the top, left on this blog).
Egyptian Starflower (Pentas lanceolata) is a flowering plant that
is actually a woody subshrub in its native habitat of East Africa and the
Arabian Peninsula. It is hardy to USDA Zones 10 to 11. In our Mid-Atlantic region, it is used as an
annual in containers and garden beds.
The star-shaped flowers
come in shades of purple, red, pink, and white. The foliage is lush and deep
green.
This annual does best in
full to part sun. It is not picky about soil type or acidity levels.
Pentas has season-long
color -- blooming all summer until it is hit by a frost in fall.
It can be grown from seed
in late winter and even over-wintered as a houseplant.
Deadhead and fertilize it
occasionally to encourage flowering.
It is a valuable source
of nectar for hummingbirds, butterflies, and other pollinators.

“Plants guided me toward a healthier relationship with myself, others, and the environment.”

This week, I was away in Delaware speaking and touring gardens, there was a little rain this week and the humidity is back. The greens and cool-season herbs that the interns planted last week appear to all be sprouting. For sure. the 'Mesclun Sweet Salad Mix' (the 3rd green stick/line in the photo above) is coming in strong. The rest (Cilantro, Parsley, 'Bloomsdale' Spinach, and two kinds of cutting Lettuce - 'Salad Bowl Blend') appear to be starting. I can see faint little green starts in the other rows, but we'll know better next week. Along the middle path (bottom of the photo), you can see the Yarrow. This herb just never quits and the interns will need to keep on top of it so it doesn't overwhelm their little seedlings.
I picked more Okra, Cucamelons, and lots of Tomatoes -- and made a few more bouquets with the Dahlias, Zinnias, and Gomphrena.
I still need to pull the Squash plant and the last three fruits forming on it. In its place, I will plant fall Peas and some Radish and Carrots below them.
I am also looking at the Basil plants and thinking I may yank them all this week to make a big batch of pesto for freezing this winter.
This weekend is our monthly HarvestShare collection and for the first time this summer I will be home for it and can donate the abundant Garlic Chives -- along with lots of Okra and Cherry Tomatoes.

Mandevilla (Mandevilla spp.) is an ornamental vine with trumpet-shaped flowers and glossy green foliage. The blooms come in colors ranging from white to pink to red as well as apricot and yellow versions.
Mandevilla is native to Central and South America and is grown as an annual vine in our region. It is hardy to USDA zones 10 and 11. It blooms all summer long until a hard frost kills it off.
It prefers full sun and well-draining soils. Plant them at the base of a trellis and they will grab on and twine around it quickly. Apply a general-purpose fertilizer to encourage flowering.
Mandevilla vines can grow up to 20 feet high.
Hummingbirds love to visit its flowers as do bees and butterflies. It is also fairly deer-resistant due to milky sap it exudes when cut.
It is a good addition to a tropical theme garden and as a thriller climbing up a support in container plantings.
You may also see the name Dipladenia, which is a close relative of Mandevilla that is a shrubbier, more compact plant that grows well in planters or hanging baskets. There are also hybrids of Dipladenia and Mandevilla available.

Can Grow That!

| Fenton plot pic showing newly planted rows of greens and herbs by Jennifer Baxter. |
This week, the weather was typical of early September in DC, some rain, but mainly blue skies and lower humidity. That allowed the interns and I an afternoon to pull out the spent Dill and other summer herbs. In their spot, the interns planted greens and cool-season herbs: Cilantro, Parsley, 'Bloomsdale' Spinach, and two kinds of cutting Lettuce - 'Salad Bowl Blend' and 'Mesclun Sweet Salad Mix'.
We picked more Okra, Cucamelons, and lots of Tomatoes -- 'Citrine', 'Sun Gold', 'Purple Tomato', and 'Fourth of July'. I also made a few more bouquets with the Dahlias, Zinnias, Gomphrena, and abundant Garlic Chives. The bees are loving those chive flowers! We will need to cut them all back soon though before they go to seed.
The Squash plant is petering out, but still has three fruits forming on it. Once I harvest them, I plan to pull them out and plant fall Peas and some Radish and Carrots below them.
Some good news, a hawk has started to patrol our garden and I have not seen bunnies in weeks -- nor other rodents. My Blackberry vines are starting to set fruit again and maybe we will even get to eat a few!

Angel’s
Trumpet (Brugmansia spp.) is a perennial plant from South
America with large, trumpet-shaped flowers that hang facing down. They bloom in
mid- to late-summer and are pleasantly fragrant, especially in the early
evening. The plant is moth-pollinated. It is also attractive to hummingbirds.
It is hardy to USDA Zones 8-10. In our region where it is not winter-hardy, Brugmansia is typically grown in a large container and then taken in when the weather turns cold. The container can be sunken into the ground during the growing season, if desired.
Brugmansia
grows best in full sun. Pot it up in well-draining soils and water it
regularly. Apply an all-purpose fertilizer regularly to encourage continual
blooming.
It can reach heights up to 20 feet tall. If it gets too big for your space, prune it back in early spring before the new season’s growth emerges. The plant is a vigorous grower and doesn’t mind a hard cut-back.
To propagate Brugmansia, take a 6-inch cutting in early spring and put it in water. Once roots form, pot it up in a 1-gallon container.
Brugmansia is in the nightshade family so it is deer-resistant, but should also be kept away from small children and pets.
