The term ‘weed’ is commonly used in gardening to describe plants that have sprouted in unintended locations. However, what truly defines a weed? What makes a plant that appears suddenly undesirable? For those who cultivate pollinator gardens, the definition of a weed may differ entirely. Pollinator gardens are primarily created to support the needs of pollinating insects and other fauna. Therefore, gardeners tend to appreciate plants that appear suddenly as they often provide necessary food sources for these creatures.
In pollinator gardens, there is one plant that is considered indispensable. Without it, the most recognizable pollinators may not survive. This plant is milkweed. Milkweed is not only the sole larval food for the monarch butterfly but also an essential nectar source for all types of pollinating insects and hummingbirds.

Unfortunately, the population of monarch butterflies has significantly decreased in recent years, with a 22% decline in population over the last year alone. The destruction of their migration grounds due to deforestation and urbanization in Mexico and California, along with the impact of pesticides and herbicides, has marred habitats around the United States. As gardeners, we cannot control most of these factors, but we can help maintain the monarch’s host plants and offer them sanctuary in our gardens. To sustain the monarch population and feed other native pollinators, gardeners should cultivate one or more of the 21 types of milkweed native to different regions of the United States.

Velvetleaf milkweed is a crucial plant for monarch butterflies flying through Florida as it is the only milkweed species that can withstand saltwater.

The scientific name for a particular plant is Asclepias tomentosa.

Type of plant that persists for multiple years is known as a perennial.

The plant needs to be placed in an area where it can receive full sunlight.

Height: 3 feet.

The hardiness zones 8-10 have a critical milkweed species for the monarch butterflies in Florida, known as the velvetleaf milkweed. During October and November, thousands of monarch butterflies stop in the coastal panhandle of Florida before migrating to Central Mexico where they overwinter. It’s an impressive sight for butterfly enthusiasts. This milkweed species is essential because it’s the only one that can survive in saltwater environments. The plant has sturdy stems with stiff leaves that have a flocked texture. The flower clusters grow on top of these stems and are typically pale green with purple accents.

Type of plant: Perennial.

The level of sunlight that a plant needs is one of the most important factors to consider when choosing the right location for it. Some plants require full exposure to the sun, while others prefer partial shade. When it comes to the latter, it means that the plant should be placed in an area where it can receive some sunlight but not too much. This condition is essential for the plant’s health and proper growth. So, if you have a plant that has partial shade requirements, make sure to find a spot where it can get the right amount of sunlight it needs.

The vertical measurement of an object is typically between one to three feet.

The white milkweed, also known as the redring milkweed, can be found in the Eastern US coast and ranges inland to Texas and Illinois.

Zizotes milkweed is an excellent choice for luring butterflies to your garden, particularly if you reside in an arid region.

The scientific name for a specific type of plant is known as Asclepias oenotheroides.

Type of Plant: Perennial.

One of the key factors for a plant’s healthy growth is sunlight. It is important to note that some plants require full sun exposure to thrive.

How tall is it?
It stands at a height of 1 to 1 and a half feet.

This particular plant, which thrives in hardiness zones 7-9, is not commonly spotted in the wild or otherwise. Despite that, it is noteworthy due to its fun name and unique characteristics. As a small plant, it stays close to the ground and boasts a foliage denser than most milkweeds, with a silvery appearance. Its flowers are also distinct, forming close to the stem and between leaves rather than in an independent cluster. The blooms have a pale green color and a hood that extends beyond the stigma and flares at the ends. This plant does well in dry climates, but it will produce more leaves and flowers after rainfall.

This particular kind poses a threat to the monarch butterflies because it is not originally from their habitat, and it could possibly transmit parasites as well as disrupt their reproductive cycle.

The scientific name for a specific plant is Asclepias curassavica.

Type of plant that lasts for more than two years is known as a perennial.

The plant needs to be exposed to direct sunlight to thrive. It requires full sun exposure.

Height measurement ranges from 3 to 5 feet.

The hardiness zones 8-11 are commonly infiltrated by the tropical milkweed, a plant that can be found in many nurseries across the country, except in California where it is banned. Although this plant is recognizable as the most familiar type of milkweed, it is not native to the United States and does not provide sufficient benefits to monarchs during their migration. Additionally, tropical milkweed is particularly harmful in evergreen climates, as it hosts a parasite called Ophryocystis Elektroscirrha. This parasite reproduces and harms the monarch population, making it a less than ideal choice for North American gardens. Furthermore, in fall seasons, it can interfere with the reproductive cycles of monarchs. The United States has 73 native species of milkweed plants that can suit every garden. These plants offer great nectar production, which helps sustain the populations of pollinating insects. Their importance as larval food for monarchs is critical, and preserving this plant is vital to the survival of this iconic butterfly species.
