SINGLE FLOWERS
1. Orchidaceae : Phalaenopsis sp.
The individual flower of a Phalaenopsis orchid is perhaps the most beautiful flower in the world. Everything in the flower is outstanding. The soft contour lines, the pastel colors and shades, even the amazing details around their reproductive structures is spectacular.
2. Nymphaeaceae: Nymphea coerulea
Several plants produce similar flowers. Even plants from different families (ex. Cactacea & Epiphyllum.)
These flowers when open are round, symmetrical and have many colorful petals and sepals.
3. Iridaceae : Neomarica caerulea, Dietes vegata
4. Strelitziaceae : Strelitzia reginae , Bird of Paradise
Perhaps Heliconiaceae can also be included in this group due to similar beautiful flowers. Heliconia Rostrata
5. Malvaceae formerly Bombaceae : Pseudobombax ellipticum

FLOWERING TREES
Fabaceaea
1. (Caesalpiniaceae):
Denolix regia:
Also known as Royal Poinciana or Flamboyant. For many is considered to be the most beautiful flowering tree in the World. During the early summer some trees are just about totally cover with orange/red flowers. It is almost like the entire tree is "on fire".
Colvillea racemosa, is a close relative that should be considered.
2. (Papilionaceae):
Butea monosperma
Erythrinas should be included in this group.
3. Bignoniaceae : Tabebuia chrysotricha
Many flowering trees in this family deserve a place in this spot, including Jacarandas, Spathodea, Tecoma and other Tabebuias.
4. Malvaceae (formerly Bombaceae) : Psedobombax ellipticum
This tree besides producing one of the most beautiful single flowers in the world is also a magnificent flowering tree when in full bloom.
Also in the same group, Ceiba speciosa, should be mentioned.
5. Melastomaceae : Tibouchina granulosa

VINES
1. Nyctaginaceae : Bougainvillea
Despite its thorns and rusticity, the beauty of a large Bougainvillea in full bloom is unmatchable.
2. Fabaceae (Papilionacea) : Mucuna bennetti
3. Bignoniaceae : Pyrostegia venusta
4. Lamiaceae (formerly Verbenaceae) : Clerodendrum
5. Acanthaceae : Thunbergia grandiflora

STRANGE PLANTS
1. Amorphophallus titanum:
This is probably the craziest wackiest plant in the World. When mature the plant sprouts a huge inflorescence and emits such a foul smell that is hard for people to get close. On top of it, the inflorescence generates heat which combined with the odor attract flies in hopes of pollination.
2. Catasetum sp.
3. Dischidia pectinoides
4. Strongylodon macrobotrys
5. Tacca chantrieri

SHRUBS
1. Rubiaceae : Ixora sp
Ixoras are perhaps the most used shrub in tropical landscapes around the
World and for a good reason. They are easy to grow, flower a lot and spectacular when in full bloom. Despite been overused it can be considered the best looking shrub in the world.
Also in the same group we should mention Gardenias and Mussendas.
2. Apocynaceas : Frangipanis; Plumeria sp.
Large family with many beautiful plants including Adeniums, Allamandas, Pachypodiums, & Tabermontanas.
3. Fabaceae - Mimosaceae : Powder-Puffs; Calliandra haematocephalla
4. Acanthaceas: Pachystachys lutea
Also in the same group Aphelandras, Justicias, Ruellias & Thunbergia.
5. Solanaceas: Brunfelsia pauciflora
Also in this group Brugmansias, Solandras, & Solanums.

POTTED PLANTS
1. Orchidaceae : Orchids
Orchids are with no doubt the most beautiful and one of the most desirable potted plants in the World. Most of the plants without the flowers are actually not very attractive, on the other hand when in bloom they are hard to resist.
2. Bromeliaceae : Bromeliads
3. Begoniaceae: Begonia coccinea
4. Apocynaceae : Adenium obesum
5. Gesneriads : (Aeschynanthus radicans)
Including Columnea, Episcia, Nematanthus, & Sinningias, Streptocarpus.
