In full sun to light shade, the plant thrives in a pot indoors or out. Provide an uniform amount of moisture and a high level of humidity. Placing a thin layer of rocks on a saucer and balancing the pot on top is the greatest technique to add more humidity to a Persian shield indoors. Fill the saucer with water. This keeps the roots out of the water while increasing the humidity in the air through evaporation.
In warm climates, Persian shield can be grown outside and planted in the ground as part of a border display. Treat the plant as an annual in cool zones or bring it inside at the end of the summer.
Is Persian shield easy to grow?
Persian shield is a low-maintenance plant. To encourage bushiness, pinch the stems back.
In the winter, keep the soil a little drier by watering the plant when the top couple of inches (5 cm) of soil are dry.
One of the most crucial Persian shield care guidelines, especially for potted plants, is fertilization. Feed with a half-dilution of liquid plant food every two weeks. Feeding should be stopped in the fall and winter.
Keep an eye out for mites and dirt gnats. Horticultural soap and soil changes can be used to tackle these issues.
Do Persian shields come back every year?
It is hardy in USDA hardiness zones 9 to 11, but in milder locations, it is most typically cultivated indoors or as a summer annual. Persian shield may die back to the ground after frost in zone 9, and during mild winters in zones 7 and 8, but it will survive and sprout the next season.
How often should I water Persian shield?
Persian shield plants need to be kept moist at all times. Twice a week, water them thoroughly and evenly. The top six inches of soil should be kept damp all of the time. Increase the amount of water you give the soil if it becomes dry between waterings. Mulch can assist keep the plants moist if they’re being grown outside.
Because moisture is so important for keeping the leaves from wilting, spritzing them with water on a daily basis is highly suggested.
How much sun do Persian shields need?
Persian shield thrives in both the sun and the shade. It requires constant watering when planted in full sun, especially in warmer areas, to keep it from wilting. Spread a 3- to 4-inch-deep layer of mulch over the soil around the Persian shield plant to make it easier to grow. This helps to keep the soil cool and moist for a longer period of time. If you grow Persian shield in pots, you can do the same thing!
Use a general-purpose fertilizer to fertilize Persian shield in the spring. For information on how much and how often to fertilize, refer to the package instructions.
Persian shield can be pruned at any time. Pinching it back every now and again promotes the plant to grow fuller and bushier, especially in the shade.
In Zone 10, Persian shield can be used as a landscape shrub. Grow it as an annual in other places.
Why is my Persian shield leggy?
There isn’t much trimming to be done aside from removing any leaves that have died back.
To encourage your plant to grow bushier, pinch back stems. This can be done whenever it is necessary.
Your plant may become leggy as it ages, throughout the winter, or if it requires repotting. Consider repotting if pinching back does not stop the leggy habit. Pinch off flower stems and trim back extra stem growth during the winter months.
While cutting the plant back to a foot tall (leaving adequate leaves for photosynthesis) at the end of the winter is optional, some people report that it spurs their plants to burst out with new vigorous growth in the spring.
Can you grow Persian shield in water?
Purple plants, in particular, have always appealed to me, even before it became Pantone’s color of the year. Purple fountain grass and Persian shield are two of my favorites. It’s easy to see why when you see those iridescent purple leaves!
Persian shields (Strobilanthes dyerianus) are really a show-stopper in my garden, bringing color and interest throughout the year. I propagate cuttings from the one plant I bought a few years ago in early spring instead of buying new plants every year (because they’re annuals in my zone).
Stella is her name. This plant spends the entire year indoors, and I utilize its cuttings to propagate new plants for outdoor containers and to give away to friends and family. There’s no bigger win for this crazy plant lady than saving money and obtaining new plants! Here’s how to do it:
Step 1:Cut a 2-3 piece from the tip of a branch above a leaf node.
I came across multiple websites recommending to cut slightly below a leaf node when researching how to spread Persian shield. However, based on my own experience, I’ve discovered that the optimal reaction – for both the plant and the cutting is directly above a node.
The cutting will begin to root at the point where it was cut, with each node submerged in water. Meanwhile, the plant will fill out with two new leaves at the trimmed place, making the plant fuller.
The cutting rooted fine when I followed the Internet’s directions and cut just below a node, however the plant’s stem was stunted and failed to continue developing. The good news is that most plants are tolerant of mistakes. If you cut the wrong area and end up with a stub, you can typically rectify it by cutting the stem lower down in the correct one.
Step 2:Remove all leaves from the bottom of stems and place in water.
Instead of directly planting cuttings in soil, peat, or sand, I submerge them in water until roots grow. Instead of using rooting hormone, I simply lay the cuttings near a bright, warm window. Make sure to change the water every two to three days, and roots should appear in approximately a week.
Step 3:Transfer to soil.
I (perform a joyful dance and) place these vulnerable newborns in little pots of soil to strengthen and thrive when the roots are about 1/21 long.
Fill the container with potting mix to approximately an inch below the rim, making sure it has drainage holes. With your finger, poke a hole in the earth and insert a cutting into it, firming the soil around the stem. Once all of the cuttings have been planted, give the pot a good drink, drain it, and return it to the sunny window. Continue to water the soil as needed to keep it moist.
Step 4:Plant outdoors.
When the Persian shield cuttings have outgrown their little pots and the danger of frost has passed, they can be planted outside in containers or straight in the ground. When they’re first released outside, they’ll be a little shocked, but with time, they’ll adjust and thrive.
Purple fountain grass, pink pentas, and lime green sweet potato vine adorn this one. (Learn more about outdoor container gardening here.)
Despite the fact that Persian shield can withstand the sun, it is best to provide some shade to keep its beautiful foliage.
What can I plant with a Persian shield?
Strobilanthes dyerianus is a delicate perennial with iridescent purple leaves that adds drama to any garden. This evergreen subshrub in the acanthus family (Acanthaceae) with the common name Persian Shield has been planted for its attractive foliage indoors and out since Victorian times. It is mainly used as a seasonal annual or as a houseplant in colder locations, as it is only hardy to zone 10 (maybe root hardy to zone 8).
When the weather is mild, Persian shield languishes, but when the weather is hot and humid, it swiftly grows into a huge, bushy, mounded plant. This soft-stemmed herbaceous shrub can reach a height of 5 feet and a width of 3 feet when planted in containers or in cooler climes, but it usually stays considerably smaller.
The lance-shaped leaves on the opposite side have lightly serrated edges and pronounced veins, giving them a quilted appearance. The foliage is a deep purple, lilac, and green with silvery highlights on older leaves, giving the upper surface a distinctive metallic or iridescent luster. The lower leaf surface is purple-maroon in color. Individual leaves grow to be 6-8 inches long and have the best color in warmer weather. Plants acquire woody stems as they mature, and the hue of the foliage tends to fade, so it’s best to start with new plants or take cuttings every year to get the most attractive foliage.
Older plants produce short conical spikes of tiny blooms raised above the foliage in moderate areas in the fall and winter. The five-lobed flowers are pale blue to violet in color and have two, three, or four stamens. The flowers arise from sticky brachts and open progressively along the spike, allowing the plant to bloom for an extended period of time. After a while, the wasted blossoms turn brown, making them unattractive for a long time. Floral buds emerge from every node once the plant produces spikes, and the stems can no longer be used for propagation. Plants are difficult to return to the vegetative stage. Bud initiation is unpredictable, and the elements that cause reproduction are unknown.
For foliar contrast, Persian shield is a nice addition to bigger gardens. It contrasts beautifully with variegated, lime-green or chartreuse-colored foliage. For a monochromatic design, pair the purple leaves with pink, lavender, or purple flowers, such as purple flowered lantana or Verbena bonariensis, or with yellow or orange flowers, such as Tithonia or marigolds, for a high contrast look. For a more refined aesthetic, the silvery highlights on the leaves mirror white flowers or white to silvery foliage, such as lamb’s ears, dusty miller, or silver Plectranthus.
Plant it alongside coleus (such as one with lime green leaves with purple veins and margins), or mix it with caladiums, elephant ears, and/or cannas for a dramatic, tropical appearance. It can be used as a temporary specimen planting in the landscape or around ponds, or it can be used to big mixed container plantings if its growth is regulated.
In northern places, plant Persian shield in full sun; in southern states, it prefers moderate shade. If it becomes overly leggy, it can be pinched back, but this is usually not a concern when grown as a seasonal annual. Provide a soil that is rich in organic matter, has good drainage, and receives plenty of water. Plants should be spaced 18-24 inches apart. Fertilize once a month. Persian shield has few pests and is said to be unappealing to deer and rabbits. Spider mites, aphids, and mealybugs can all infest indoor plants. In frigid locations, this plant may typically be kept over the winter by digging it up in the fall (long before the first frost) and storing it indoors in moderate light. Plants may lose all of their leaves, but they should reappear in the spring from the roots.
Cuttings are commonly used to propagate this plant, but it can also be cultivated from seed. Early spring or summer basal or softwood cuttings root quickly in water or damp medium. Cuttings can also be collected late in the summer or early in the fall and brought indoors to overwinter.
There are about 250 other Strobilanthes species, including S. maculates from the Himalayas, which has silver-splotched leaves, and S. lactates from Brazil, which has white blotched leaves, but none of these are widely available as ornamentals.
Why is my Persian shield crispy?
Dry air causes brown, crunchy leaves. This inhabitant of the tropics prefers damp air to look its best. Take a look at these simple methods for increasing the humidity in the area. When the roots have filled the pot, repot in the spring probably every couple of years.
Why is my Persian shield turning green?
Too little water and much sun exposure cause curled leaves and brown leaf edges. Persian Shields thrive in bright, indirect environments, and those who haven’t acclimatized to the intense rays will display signs of sunburn and shock. Winter sunlight is fine as long as the soil moisture is monitored on a regular basis, but once summer arrives, it must be avoided completely.
