Types of Castor Flowers: Summary of Castor Flowers


Castor flowers are beautiful, but they don’t really look good. They can be male or female and the only difference between them is that the males produce the seeds while the females need bees for pollination. Male flowers are white in color with yellow pollen, while females are red in color and give off a foul odor.

Both types of castor plant attract important pollinators like bees due to their distinctive coloring and structure. Castor leaves are poisonous to all animals except cattle, so it’s best to keep them out of the reach of young children if you have livestock on your property.

Pollinated castor

Pollinated castor seeds develop inside a flower. Each flower has two types of petals: the outer shell-shaped sepals and the inner petals which are the same color as the seed coat of castor seeds. The latter are smaller than the sepals, but they attract bees and other pollinators. Pollination is about 50 percent among flowers of different types.

Knowing the type of castor bean flower is crucial as it will help you determine how many pollinated flowers to expect from each plant and how long it will take for the castor seeds to be ready for harvest. It should be remembered that the average time from planting seedlings to the first harvest of live, polished castor beans is about five years.

Bright Red Carmencita

The bright red Carmencita castor flower is a variety of castor bean that has been found in Mexico City, Puebla, and Orizaba. The plant was named after Carmencita Rocha who first discovered it in 1988. Carmencita is also known as the red star due to its star-shaped flowers.

The Carmencita has a compact, round shape that is about four feet wide and averages six to eight years old before producing flowers. It has distinctive large red flowers with white edges that have fringed petals, longer than the normal castor flower. Carmencita seeds do not germinate when planted.

Carmencita is a slow growing plant and is known to thrive in different types of soils that contain clay or sand, but the best type of soil they can live with is rich sandy loam. Carmencita can be grown as long as it receives water during the summers. The flowers bloom from June to August and can be seen throughout these months.



This plant can reach a height of 4 to 5 feet and has pink colored pods with leaves in dark red tones. USDA zones are 5 through 11 for this cultivar and the flowering season is from late summer to early fall. For this thorny plant, full sun is ideal for healthy growth.

Well-drained soil with a pH of 5.8 to 7.0 is best for this plant. The seeds of this cultivar should be planted 0.25 inches deep and should be spaced 36 to 46 inches apart so that they have enough room to grow. The seeds of this variety are very poisonous and should be kept out of the reach of children to avoid dangers of any kind.

The average germination period is a week or two weeks at a temperature of 65 to 70 degrees Fahrenheit. This plant can really add an exotic touch to the landscape. Fertilization is necessary every month for the healthy growth of this variety.


Roulette Impala

The Impala Beaver is a widespread invasive species and can be found on the continents of Africa and Asia.

The flowers are large, 6 to 8 inches, fluffy white solitary flowers that emerge from a small brown colored bud. The flowers themselves have five petals, with the upper two being very large and fringed while the lower three are smaller, but not much less substantial.

The Impala Beaver also has a shiny green stem that can grow to 10 feet tall and is streaked by its many aerial roots. It will produce thousands of castor beans, each covered with a thick mucilaginous substance. The seeds of the plant are relatively large and thin, measuring about 3 cm long by 2 cm wide.


Sanguinesus is the genus that all castor seeds belong to, but it is recommended that you get your seeds from a place that sells species-specific (not sanguineus-specific) seeds. The reason is that although they are obviously different plants, some of them are very good ornamentals and others have toxic properties. Unlike many plants, they are initially edible and remain so for most of their lives. Sanguineus castor plant from a supplier specific to sanguineus

There are 70 to 100 species in the genus Sanguineus, all of which have at least partially red flowers. Most of them also have pinkish flowers most of the time. They are not very big factories either; most of them are four feet tall or less.


This cultivar has large, single, deep red flowers. The floral bracts are carried and later fall to the ground. This cultivar is a full sun plant with pale green leaves. It will grow alone five feet tall without any support. Zanzibarensis is a tropical plant that must be protected from freezing temperatures.

This cultivar features indigo blue flowers with gold leaves. The flowers are usually carried upwards, although they may also drop when the bracts open. It will grow four feet tall without any support and plants in full sun should be protected from freezing temperatures.

Red Arrow

This cultivar can reach heights of 7 to 10 feet. It has red stems and red pods with leaves that almost look like bronze. The flowers are red in color and the flowering time of this plant is summer, early fall, or late fall. It prefers mesic water and the flowers and fruits are showy. It attracts bees and butterflies and is resistant to deer and rabbits. Leaves, roots, fruits, seeds and all other plants are poisonous and should be kept out of the reach of young children. Full sun or partial shade is ideal for the growth of this cultivar. When growing, these should be spaced 36 to 48 inches apart for healthy growth.

New Zealand Violet

New Zealand Violet

This one branches less than the other varieties and has smaller, reddish-purple leaves. This fast-growing cultivar has hardiness zones 9 to 11 and is annual in the other zones. Other than that, full sun is great for growing this plant, as well as dry, sandy soil. The color of the foliage is very striking. This cultivar can reach heights of 10 feet in a single growing season. Care should be taken around children and pets, as the seeds are very poisonous. The seeds take 12 to 14 weeks to flower. This plant has a glossy texture and is resistant to deer.

Rose Carmencita

This cultivar has pinkish red panicles and pods. Well-drained soil with around 30% clay is ideal for the growth of this variety. It grows well at a temperature of 12 to 15 degrees centigrade and temperatures below 10 degrees centigrade can only be tolerated for a very short time. Lots of balanced fertilizers should be used for healthy growth of this plant.

Strong sun exposure ensures better growth and the cultivation time is around 9-10 weeks. Poisonous seeds should be kept out of the reach of children. It is a semi-hardy plant that can reach a height of 90 centimeters. It can be used best as a solitary plant for borders or containers, as a medicinal plant, oilseed plant or ornamental leafy plant.

Carmencita Rose

Carmencita Rose

Carmencita Rose is just one of the castor bean flowers. Castor seeds originated in East Africa, but have spread around the world and ended up in our backyards.

Although they are native to East Africa, they can now be found all over North America as well as other countries. Castor beans need warm temperatures to grow. They are found in regions as diverse as the United States, Central Africa and India.

This is characterized by bluish green foliage and pods of various peach shades. This plant is relatively miniature and the flowers bloom throughout the season. USDA zones range from 6b to 9b. This plant is very vigorous and is just as poisonous as the others and should therefore be kept out of the reach of small children. He was first bred in 1954 in Spain by Cebria Camprubi Nadal.


How long does a castor bean flower last?

Each type of castor flower lasts only one day. This is one of the reasons why bee flowers have become so important to growers; on the day of their flowering, you can collect thousands of seeds from a single large plant.

Why do castor flowers attract bees?

Female and male plants both have very different flower structures, which is important in attracting pollinators – bees in this case. The white flowers of the male castor plant are one of the most attractive to bees, hence the reason they are planted with female plants so that bees can easily pollinate them.

How to get rid of castor plants?

If there are only a few castor bean plants close to each other, you can remove the entire plant from its roots, including the underground stems. However, if there is a bunch of castor bean plants in an area then you will need to use herbicides to get rid of them as manually uprooting them would take too much time and effort.

How to recognize castor plants?

The easiest way to identify castor bean plants is to look for clusters of large, yellow flowers.

Where do castor seeds grow?

Castor seeds can be easily purchased online and in local stores as well. They are simple to grow if you know what climate they need the most and how much water and sun they need to grow so you can easily grow your own castor beans.


There are many types of castor bean flowers, but they all attract important pollinators, especially bees, due to their distinctive color and structure. On the other hand, male and female flowers serve different purposes for the castor plant, as females need bees for pollination while males need them for producing seeds.

In addition, the leaves are poisonous to all animals except livestock. Therefore, if you have livestock, it is best to keep the plant isolated in a supervised place.
