How Many Types of Blue Flowers Are There?
There are thousands of blue flower varieties on earth. It would be impossible to know the exact number but according to some studies, it is estimated that there are about 280,000 flowering plants and about 10% of them bear blue flowers.
The blue color, however, varies from one plant variety to another and from different conditions where the plant is kept.
What Are the Little Blue Flowers Called?
The little blue flowers are called hyacinths. These flowers symbolize peace, beauty, hope, and commitment and are seen in clusters of small blue flowers. Examples are the Grape hyacinth and the dwarf morning glory among others.
Naturally Blue Flowers
Natural blue flowers exist in good numbers. Their blue colors vary depending on the plant variety and conditions. Some of the naturally blue flowers include the cornflowers, the blue mist shrub, Love in Mist, Lungwart, Siberian Squill, Lobelia, Columbine, sweet pea, morning glory, delphiniums, and hydrangea among others like:
Clematis – Scientifically known as Clematis occidentalis and need well-drained soil, full sun to partial shade, and thrive in fertile soil.
Wild sage – scientifically known as Salvia verbenaca and grows well in moist and well-drained soil or humid conditions, and in full sun exposure.
Natural blue flowers are highly regarded due to their value across cultures and even in professions. They mean good tidings and, in most cases, blue flowers come with serenity, hope, inspiration, health, wisdom, stability, and other good meanings. In rare cases and cultures would a blue flower mean bad news.
Are There Any Blue Lilies?
Blue lilies do exist. These can include Agapanthus praecox, Nymphaea caerulea or the Egyptian Blue Water Lily, and Nymphaea violacea. Blue lilies are regarded for their high ornamental value and what they mean. These flowers symbolize inspiration, tranquility, and hope. These lilies need different conditions for them to bloom.
Agapanthus praecox – This blue lily plant needs loamy soil that is rich in organic matter and with a lot of water. They are sub-tropical and also need full sun or partial shade. To grow in pots, you may need to provide these conditions for the plant to thrive and bloom.
Nymphaea caerulea – this is an aquatic plant and needs a lot of water to grow. Their flowers are not blue per se but are almost a purplish tone. They thrive in slightly acidic to neutral soil, undisturbed water, and in full sun.
Nymphaea violacea – this is a floating perennial herb that bears blue flowers. It is considered a blue lily and grows well in loamy wet soil. They thrive well in wetland habitats with full sun exposure. Also, they need a pH that is acidic to neutral. When the right conditions are met, the plant blooms during summer, winter, and autumn.
What Is a Blue Hydrangea?
Blue hydrangea is a member of the Hydrangeaceae family, scientifically known as Hydrangea macrophylla. It is a kind of deciduous shrub that grows up to 7 feet tall and bears blue, purple, white, and pink flowers during summer and fall.
The Blue hydrangea needs moist and well-drained soil, acidic and alkaline pH, and thrives well in full or partial shade. The plant, however, does not need too much sun exposure, too much shade, or too much dry soil. For the hydrangea plant to bloom, these conditions should be kept.
What Is the Rarest Blue Flower?
Blue flowers are rare but when it comes to the rarest of the blue flowers, I would say Grape Hyacinth, scientifically known as Muscari armeniacum is a rare blue flower. One of the reasons why the Grape Hyacinth flower is rare is because the plant doesn’t like extreme conditions that are too wet or too dry.
Grape Hyacinth is a bulb plant that grows well in well-drained and moist soil. It also does well in full sun or partial shade. The clumps of this plant spread quickly but only blooms in April and May. That is another reason why these flowers are rare.
