A Buyers Guide to Popular Tropicals part 3




Plants go dormant from November to May. Rhizomes can be dug up and stored in November. For years we have supplied Americas' premier botanical garden, Longwood Gardens, with Siam Tulip rhizomes, which every summer elicits more inquiries and comments than any other plant at the Gardens. It looks just like a pink tulip growing in the dead of summer, which just can't be? Now the Siam Tulip comes in a variety of colors from pure white to ruby red.

Caladium sp. (Thai Beauty) is a caladium from Thailand that looks too good to be real. About 10 years ago, I was told by a Thai tropical plant nursery about a wonderful new caladium they had found. I ordered some bulbs and was pleasantly surprised and extremely pleased at the resulting plants.

There are hundreds of caladium varieties; however I haven't seen any that I like better than the 'Thai Beauty', which I named. It has always reminded me of a thin, delicate sheet of living, stained glass that was put together by the great artist of nature. The pieces of "living glass" are mostly translucent pink with some white, while the solder frames are jade green and white. The leaf is wavy and heart shaped with a point. Like finger prints, no two leaves are alike-everyone is unique. The 'Thai Beauty' is perfect for containers, planters, or beds. It works indoors or outdoors and grows best in bright indirect sunlight. Bulbs may be left in the ground (in well-drained soil) throughout the year in Zones 10 and 11. In Zone 9, digging is recommended, as bulbs may be damaged by cold and wet winters. In other areas of the country, bulbs must be dug up each year before frost. The 'Thai Beauty' can be used as a bedding plant for foliage, in planter boxes, edging, or pot plants. To be sure, the 'Thai Beauty' is a joy to behold.

Equisetum hyemale (Horsetail Fern or 'Scouring Rush') is a living fossil. It was abundant at the time of the dinosaurs. And it could have very well been dined on by the dinosaurs, particularly the herbivores that grazed along water margins. Horsetails belong to a class of their own and have no direct affinity with any other group of plants with their nearest ally being the ferns. Horsetails are exotic looking, easy to grow, attention getting, work great in containers, planters, beds, and compliment any water feature. They have a very distinctive jointed, almost "bamboo look." They prefer afternoon sun but can grow in full sun.
