Queen of the Night (Epiphyllum oxypetalum)

Catching a glimpse of this cactus’ blooms, also known as Kadupul flowers, takes a fair bit of patience. Not only do the plants rarely bloom, but the flowers emerge at night and wither by dawn. While the plants are native to Mexico and South America, you can grow them indoors. Additionally, cultivated plants have escaped and can now be found throughout countries like Sri Lanka.

Catherine-Wheel Pincushion (Leucospermum catherinae)

A type of protea, this flower is perhaps the most attractive member of the group of fireworks pincushion flowers. While you may think the elongated portions are petals, they are actually individual flowers. This protea species is considered endangered in its native South Africa.

Ghost Orchid (Dendrophylax lindenii)

While the ghost orchid’s white flowers are unique, what really sets it apart is its lack of leaves. Unlike most plants, this orchid photosynthesizes via its roots rather than its leaves! Like a ghost, it can be a bit elusive to find since the species is endangered in its native habitat of Florida and Cuba.

Darwin’s Slippers (Calceolaria uniflora)

A member of the slipperwort family, this plant is native to the southern tip of South America. While the name suggests the flowers look like a pair of slippers, some people think they resemble flocks of orange penguins or aliens with their mouths wide open. These plants are quite rare, and it’s not uncommon to find counterfeit seeds.

Jade Vine (Strongylodon Macrobotrys)

Native to the Philippines, the jade vine produces hanging clusters that can contain up to 75 of the stunning turquoise flowers. Since the flowers resemble claws, the plant also goes by the name tiger claws. The hanging flowers are pollinated by bats, but deforestation in the Philippines is threatening both the flowers and the bats.

Lady’s Slipper Orchids (Cypripedium spp.)

Although these flowers are orchids, they look quite different from the ones you may have growing in your home. They emerge from forest floors across the United States and other temperate areas, but finding one can take some patience as well as knowledge of your local area. There are numerous species of lady’s slippers, including the showy lady’s slipper pictured above.

Purple Passionflower (Passiflora incarnata)

While this flowering vine is native to the Southeastern United States, it certainly provides an exotic look! Since each flower blooms for only a day, it’s a treat to come across the wild blooms. If left to mature, the flowers will transform into sweet and juicy passionfruit. The purple passionflower is also the state flower of Tennessee – check this out if you’re interested in learning all 50 state flowers.

Himalayan Poppy (Meconopsis betonicifolia)

While flowers come in all kinds of colors, true blue blooms can be a bit difficult to find. Himalayan poppy flowers bloom for only a few days, but they make a stunning display while they last. Like most poppies, you can grow the delicate flowers from seed. However, before you plant these flowers in your garden, you should be aware they can be a bit difficult to grow.

Chocolate Cosmos (Cosmos atrosanguineus)

You may already have some pink or white cosmos flowers in your garden. But how about chocolate cosmos? These tuberous perennials are native to Mexico, where they thrive in sunny and dry environments. With the right care, these plants will produce handfuls of dark red blooms that smell like chocolate! While they may smell enticing, these flowers don’t taste like the candy bars we love.

Bleeding Heart (Lamprocapnos spectabilis)

Native to forests in China, the bleeding heart plant will thrive in many temperate gardens. These large, herbaceous plants produce hundreds of pink flowers that resemble the namesake bleeding hearts. Since these plants thrive in shade, they make a great addition to forest understories or shade gardens.
