In order to take proper care of your Bottlebrush Buckeye you’ll need to keep in mind the following guidelines:

  • Light: Keep your Aesculus Parviflora in an environment where it can receive partial to full sun on a daily basis. 
  • Soil: Make sure to keep the Bottlebrush Buckeye in soil with moist but well-draining properties, so ideally, one that is made of clay, loam, chalk, and sand.

And as with many other plants, these are the only three care factors you need to remember to make sure your Bottlebrush Buckeye is, for the most part, healthy and well to survive.

Scientific / Botanical Aspects

In botanical terms, the Bottlebrush Buckeye belongs to the Sapindaceae family, the genus Aesculus and the species Parviflora, hence its scientific (or botanical) name Aesculus Parviflora (es-KU-lus par-VEE-flor-uh).

As with other Aesculus’s, the Bottlebrush Buckeye is a deciduous plant, which means it will shed its leaves annually once autumn comes.

Growing Region

The Bottlebrush Buckeye is a plant native to the Southeastern US. This is why the Aesculus Parviflora is used to growing in specific regions such as the states in Northeast, and the Southeast of the United States.

You might be wondering why your Bottlebrush Buckeye’s native region is essential. Well, if you know where your plant originally came from, you’ll know which environmental conditions it prefers, and with it, knowledge on how to replicate it at home.

With this in mind, the Aesculus Parviflora will be most used to the heat zones in the 4 – 9 region, as the plant hardiness level falls between 4a, 4b, 5b, 5a, 6a, 6b, 7a, 7b, 8b, 8a.

Growth and Size

Growth

In terms of size and growth, the Bottlebrush Buckeye is a relatively moderate grower, which makes things somewhat easy for any plant enthusiast.

Size

But, what size of Bottlebrush Buckeye are we talking about? What can you expect in terms of height, spread and spacing? Let’s dig in…

The Aesculus Parviflora can grow up to 8′ – 12′ (240cm – 3.6m) in 8′ – 12′ (240cm – 3.6m) and 8′ – 15′ (240cm – 4.5m) in 8′ – 15′ (240cm – 4.5m). 

These dimensions make the Bottlebrush Buckeye a relatively large shrub compared to others, so it’s best to keep this fact in mind since it will affect where you want to keep yours at home.

Also, expect it to grow in a wonderful rounded shape, which is something worthwhile to remember when making your garden landscape plans.

This is why experts recommend keeping an area of approximately 96″ – 120″ (240cm – 300cm) free so the Bottlebrush Buckeye can spread to its best extent.

Watering

In terms of watering, the Bottlebrush Buckeye is a fairly complicated plant to take care of. This is mostly because it has a not so straightforward watering schedule and somewhat irregular watering needs.

Specifically, most experts agree that the Aesculus Parviflora needs evenly spread moist soil – try to avoid letting the soil dry out.

Which is why it is considered a plant with relatively average needs in terms of water. 

As a rule of thumb, you should remember to keep your Bottlebrush Buckeye in soil with moist but well-draining characteristics, as these will guarantee the right conditions for your plant to grow and thrive. 

When you consider this, this is why you should aim to choose soil that has good drainage properties to keep the right moisture levels at all times. 

In our experience, the famous ‘thumb’ or ‘finger’ test is what works best for the Bottlebrush Buckeye since with it, you will be able to give it the right amount of water, every time – regardless of the environment or placement where you do decide to keep it.

Soil Mix

As mentioned earlier, the Bottlebrush Buckeye prefers to have soil with good drainage properties at all times, reason why you need to make the soil mix out of clay, loam, chalk, and sand.

This is why most experts agree that the Bottlebrush Buckeye requires soil with high organic matter, which will give you the right conditions it needs.

In addition to this, expert gardeners recommend having preferably alkaline, acid or neutral soil.

Light and Placement

In terms of light & exposure, the Bottlebrush Buckeye requires partial to full sun in order for it to thrive under the right conditions. 

Most experts agree that this shrub will do well as long as you keep it in shade, or partial sun to full sun, and it will be able to grow properly.

Specifically, we recommend that you place your Aesculus Parviflora in little to partial shade (only 2-6 hours of direct sunlight a day), to full and direct sun (more 6 hours of direct sunlight per day).
