Persian Shield – That Pretty Purple Plant

Its name is Strobilanthes dyeriana “Persian Shieldand it is such a stunning color in your garden or containers. Be ready with that name because you will be asked time and time again.

This  beautiful plant that I have on my front porch in matching urns has grown so well this year. It is partly shaded through most of the day and that helps it keep its rich purple color. Too much sun can fade it.

I have mine planted with a sweet potato vine which is a great color match for its undertone. Yes, I planted a real sweet potato in the urn (not the ornamental type) and it has really grown. I guess I could dig sweet potatoes if I wanted. But that green perfectly matches the stripes in the purple Persian shield.

I wish that I had planted the ornamental sweet potato vine, though. I think that neon green would have been even prettier, don’t you think?

Persian Shield - Outdoors for stunning color or indoors for color all winter

The Persian shield can also be a beautiful houseplant if you want to bring it inside. I plan to cut several slips and root them so that I can bring it in and save it for next year. Outside it can be in a container or in the ground. 

Persian shield can get very large as it continuously spreads across the ground. Just pinch the branches to keep it tidy in a container or just let it sprawl and crawl across the beds.

I usually find my plant in the spring in a nursery. It is a little expensive since I paid $10 for a small plant, ( I bought two) but I think it is worth it. After all, it quickly grows to about three feet all and wide in a pot, but seems to be less tall when planted in the ground.

Persian Shield Blooms

I have never had the pleasure of seeing my Persian Shield bloom, but it can bloom with pretty blue flowers. I guess the season here in Ohio is not long enough and conditions may not be right inside for mine to reach bloom stage, but someday I may get lucky.

The flowers are small and the foliage is so pretty, I don’t mind if mine never flowers. ( Though I would like to see it just once.) 

This year in the new house, we have large basement windows where I can put houseplants, so I may get lucky and see these flowers for the first time.

Take cuttings of your Persian Shield for an indoor houseplant over winter

Be sure to wash off the cuttings under running water and inspect for any infestation.

The last thing you want to do is bring insects or eggs into the house for the winter. Fighting them off all winter would be a nightmare.

I speak from experience and have learned from my mistakes. See this post for bringing in your potted plants.

Large window for houseplants

I am supposed to be exercising on that elliptical machine, but I just can’t seem to find the time. (snicker) It is my daughter’s and she is able to whip through a session, but seriously, I can only last about 15 seconds and I am whipped.

I must not use “those muscles” when I garden. Well, someday I may master it. But it won’t be today. With my plants in there, if they ask me if I have been in the Exercise room, I can honestly say “Yes, I have.” (snicker)

  1. Would a self watering pot be good for personal shield?

    1. I think that would be great since they wilt so easily when they get dry.

    I just bought a Persian shield , it’s small , I paid 4.99 , here California can’t wait to see it show me it’s beauty

    1. Oh my, congrats. I can’t wait to get one this year. Such a pretty plant!

    I think Persian Shield is gorgeous. Once I moved mine to semi-shade the color improved. I think you made the right choice using a regular sweet potato. I tried the Marguarite (light green) and the roots are WAY too invasive. Perhaps next year I will try a white Calibrachoa. They do well here in NW Ohio. 🙂 Now, I’m off to get some cuttings!

  4. Sounds wonderful. I have a hard time growing through the winter and usually have to find a new one in spring. Hope you have a huge one this year!
