Balcony Garden Update, May 2025

The Mission:

This is the third year I've chosen a native rush to fill the planter boxes that line my west-facing 13th floor balcony.  Grass seems to be a good plant for the balcony (or a rush in this case, it is not technically a grass) because it visually softens the concrete and metal edges of the balcony. Few other traditional annual plant species tolerate deep shade for most of the morning, followed by intense afternoon sun, and constant wind. Plants that have medium to large leaves (e.g. tomatoes) get shredded by the wind. Grasses and rush grasses will tolerate wind, heat, and some degree of drought.

The Plant:

Juncus inflexus, commonly known as blue arrow rush. It grows to a height of about 24 inches in the 5-gallon planter bags (but would likely grow higher, to 36 inches, if planted in the ground). Native to northern Europe and Asia, Juncus is also considered native to eastern North America.

Although its seed heads are small and indistinct, the blades have a muted blue-green color during the growing season, turn reddish in the autumn, and light tan through the winter months. During the winter, they are especially attractive when covered with snow.

Juncus typically grows near boggy soil, but it also seems relatively drought-tolerant on my hot and windy balcony. During the growing season, I tend to use 6 gallons of water each time I water them (24 grow-bags each with three plants). In the past, I've found they need water two or three times per week. However, if they get rain, I'm able to water them less frequently.

The Technique:

For specific details on how I fill the planter boxes, see my prior posts on this topic. This year, I chose to reuse the planter bags from the previous year. The plants had dried over the winter, allowing the bags to be easily removed from the boxes, and the shriveled roots separated from the planter bag fabric without too much effort.

The Price:

Let's be honest, this mission is not inexpensive. The planters can easily accommodate 72 plants, each priced at about $13. Add on the price of the potting soil, 4-5 bags, and the total price starts to rise over $1000. It wouldn't be so bad if they would survive the winter, but their roots freeze solid up on this balcony. If I want the greenery, I have to accept that they are annual plants.

Last year, the supplier gave me the discounted price they give to most contractors, at $8 per pot. But this year, the salesperson refused to give me the contractor's discount. Grrrr... especially since I bought 72 plants!

Further adding to the price is the cost of driving 20 miles to the garden center, a 40-mile round trip. I had to make the trip twice to fit all 72 plants in my little hatchback car.

And finally, the amount of waste is embarrassing. I'm sad there's no way I've found to recycle the spent nursery pots.

Is It Worth It?

I understand that for many people the price wouldn't be worth the effort or the result. But for me, yes, it is worth it. I love seeing the color and movement out on my patio all year long. The planters can be viewed from most rooms of my apartment, bringing a bit of the outside indoors. I no longer have a backyard garden to play with, so this collection of planters is mine to spoil.

The set up: I've found kneeling on a pad easier than standing at a bench.

I celebrate learning this about cycad plants

I didn't know that the cardboard palm - Zamia furfuracea - is a cycad. It isn't a palm tree (don't judge me, I'm not a botanist). But it also doesn't look like the other more familiar types of cycads with their fluted upright palm-like fronds. I didn't know it is said to be the second most commonly cultivated cycad, after Cycas revoluta . I didn't know this plant is unrelated to the common ZZ plant - Zamioculcas zamifolia - although they have a similar appearance. Before today I didn't know any of these things, but now I am happy to have learned them. From the parking lot I walked to the U of M Conservatory greenhouse in near-zero F weather. Stepping into the tropical spaces was a joy of its own. But being able to learn new information and experience new procedures was a compounding factor. Joy squared. During my 3-hour volunteer shift, my initial task was to clean the parasite critters (mealybugs and scale) from the stems and leaves of the cycad, Zami...

Another routine spectacular day in the greenhouse

It has been a sincere pleasure for me to volunteer a few hours a week at the University of Minnesota Botanical Conservatory. After many visits over the last few years, exactly none of those days have felt ordinary or repetitive. If there is a routine , it is that the botanic diversity of the collection - with over 3000 species - is displayed in a spectacular way each day. The Conservatory is located on the St. Paul campus, and is free of charge and open to the public during typical weekday hours. For instance, today most of my allotted time was spent in just one of eight rooms, the room that houses the tropical collection. The chores included pruning, re-potting, spraying, sweeping, etc. As I moved through the room, in every direction, there seemed to be a stunning plant pleading to be admired.  After the chores were complete, I had the opportunity to go back and photograph some of the beauties that surrounded me while working.  Dendrobium tangerinum , Papua New Guinea Dendr...

Botanical Garden of Prickly Plants in Palm Springs

This adobe wall and gate are part of the original hotel in Palm Springs, California. In 1938 the old adobe hotel was purchased by Chester Moorten, who had previously been a stunt man in early Hollywood working on films including the Keystone Cops movies. He and his botanist wife Patricia, lived and operated a desert garden center out of the old hotel. Locally he was known as "Cactus Slim" for his ability to maintain desert plants. Chester's son, Clark, carried on the business and became a noted expert in desert plants. Clark Moorten still owns and operates the Moorten Botanical Garden which is open to the public (except on Wednesdays, which I discovered the hard way). Original adobe wall of the old hotel, now Moorten family home Layout of the botanical garden Compared to other botanical gardens, this one is limited to one acre. However, what it lacks in size it compensates with variety and quality. There are specimens in this garden that would be difficult to find in the ...
