Knowing the Basics of Planting Silver Dollar Plant

Would you be surprised if we told you that growing a silver dollar plant is as easy as throwing it on the ground and watching it grow? Sounds too good to be true, right? That’s how it is actually, especially if you enjoy seeing bright purple blooms popping around your garden.

But, we all want to grow our plants in an organized manner, don’t we? If you are one of those people, this part of the article should give you a comprehensive outlook.

Basics of Planting Silver Dollar Plant

We will discuss three factors that go into growing the silver dollar plant – when, where, and how.

Let us discuss them in detail:

When should you plant it?

Lunaria is a perennial flowering plant. Does this mean that you can grow them any time of the year? Well, that’s where you are wrong. The start of the spring or peak summer months is considered ideal for growing these plants. But, since they are biennial plants, their growth pattern is comparably slower than most of the other options available. If you want to witness the flowers, you’d have to be patient for a year or so.

Where should you plant it?

The next factor worth considering is the place of the plantation. Should you select a random patch of soil and then plant the silver dollar plant? Technically, no. You need to find a space in your garden that is lightly shaded but not shedding direct sunlight on it. It is an amazing self-sowing plant, which means that you can grow it at an exponentially high rate without any complications along the way.

How should you plant it?

The last factor that you need to consider is the process of growth. What kind of care guide or growing tips should you keep into consideration? They need good air circulation between each grown plant to ensure that they grow exponentially and without unnecessary lags in the process. You can also sprinkle a good handful of organic matter around the soil for more even growth of the plants.

Now that you have a basic idea about its growth requirements, the next factor worth considering is the growing guide. In this section, we focus on finding out some of the most crucial factors involving the transplanting process, the kind of soil and light parameters the plant needs, etc. 

You will often find the plants growing around the woodland borders, especially because they line the perimeter of the garden well and looks pretty enticing. With the right conditions, the plants will thrive like no other, making them an optimal growing option for beginners.

The seed pods that grow out of the flowers are what set them apart from the rest of the similar plants. You will often find them growing at an exponentially faster rate, especially around the second year once the blooming starts.

The seed pods are known as silicles, which typically start with the staple green color and then gradually shift and change their color to a lighter, almost silver shade and hence the name. It has a subtle off-white sheen to the pod, which is where it gets its name from.

Given the stunning appearance of the pods, you will often find them dried in the majority of the floral arrangements in the events that you attend. 

Moving on, let us discuss the growing guide for this plant. Remember that being on par with these individual growth patterns can effectively help you understand the right parameters that you need to follow to ensure the plant grows optimally.

  • Light parameters

We are talking about sunlight and sun exposure. Since silver dollar plant is highly versatile, it isn’t surprising that they can thrive in direct sunlight and even in partially shady areas. Just ensure that they get enough sunlight to grow optimally and grow brighter and more vivid blooms around.

Experts suggest ensuring that the plant is getting around 8-9 hours of direct sunlight every day. This supports the flowering process and keeps the roots strengthened.

  • Soil requirements

Soil is no doubt one of the most crucial parts of growing a plant. If the soil isn’t of prime quality, it will eventually tear down the quality of the plant. Since they have a very strong rooting system, it isn’t surprising that the soil needs to be compact and deeply rooted to support the growth of the plant.

When it comes to the texture of the soil, you have to pay close attention to include a mixture of soil types, including well-drained and humusy texture. Your aim with the soil for the silver dollar plant is to have a soil type that is not waterlogged and at the same time moist and well-hydrated.

If the soil is dry and lacks enough moisture, it will dry out the roots, leading to complications relating to the growth of the plant. 

  • Water parameters

Next on the list of considerations is the water. How much and how often should you water the soil? Should it be every few hours, once a day, or more infrequently? The silver dollar tree needs moist soil to thrive. So, your soil should have around 1-inch of water in the soil to support optimal growth.

However, this one inch of water should be enough to get you through the week. So, you aim to stay vigilant throughout the week. If you want the water drying out quickly, you can re-water the soil to restore the moisture level. But, if the water is sufficient in the soil, avoid overwatering because that can lead to complications of root rot.

  • Temperature and climate

Growing a plant is heavily influenced by the kind of climate it is surrounded with. For the silver dollar plant, it requires a somewhat warm temperature between 60-70 degrees Fahrenheit.

However, the one good thing about Lumaria is its hardiness. Once the germination occurs successfully, you won’t have to worry about maintaining the temperature settings separately, which is a big benefit to the process. 

  • Added support

This includes the need for compost or fertilizer. Does the silver dollar plant require external fertilizer? It isn’t mandatory but sprinkling a bed of slow-releasing fertilizer once a year in the soil bed of this plant is considered enough.

It supplements the plant with the much-needed nutrition, ensuring that the blooms come out bright and stunning the next year.

  • Neighboring plants

Can you grow additional plants around the silver dollar plant? The answer is yes. The silver dollar plant isn’t intrusive to the growth of other plants, which means that you shouldn’t have any issue growing other flowering or non-flowering plants around it. 

Some plants like Hakone grass and Forget Me Nots are considered ideal for growing around the silver dollar plant. Adding an herb patch is considered ideal if you want to attract necessary insects and critters into your garden.

How to Prune the Silver Dollar Plant?

Lunaria grows at an exponentially faster rate and proliferates at a rate that you normally wouldn’t expect. Their growth might seem invasive but they are far from it. With the right growing conditions, a single stem of the plant can proliferate into multiple plants.

Prune the Silver Dollar Plant

The easiest way to grow the plant in the right way is to support its growth by pruning the leaves and the overgrowing stem. Pruning should start after the seed pods are completely developed. Don’t do anything before that because that will affect the quality of growth of the plant.

How to Harvest and Store the Silver Dollar Plant?

Most gardeners and professionals grow Lunaria for the seed pod which is a crucial part of most of the dried flower arrangements in the events. So, you will often find them sold as a decorative element.

If you want to add that element of elegance to your home décor, you can harvest and dry the seed pods once they bloom in the plant. You need to wait until the seed pods are completely brown before you can go ahead and dry them.

Harvest and Store the Silver Dollar Plant

The easiest way to dry out the seed pods is by snipping the stems out of the plant and then hanging them in a cool and dry place for them to dry out. Once dried and brown, you can take out the seed pod and then rub them between your fingers. 

For optimal storage, keep them in an airtight container. Avoid keeping it in a warm place in the house because that can end up damaging all the hard work that you have put into growing the plant.

If you feel the soil is still wet, it is ideal that you avoid any kind of rewatering until it has dried up entirely.

Silver dollar plants aren’t invasive like most perennials are. But, they do grow on their own if you spread around the seeds and the right growing conditions. One plant easily multiplies into more in no time at all. So, in that way, growing these plants might seem a little too out of control at times.
