Plant of the Month: July 2011

Siam Tulip
aka Summer Tulip, Thai Curcuma, Land Lotus
Curcuma alismatifolia





Family: Zingiberaceae
CH Zones: 9-11 (winter dormancy)
Size: About 2 feet tall and wide
Cultivation:  Takes all light conditions, but performs best in part shade; late afternoon sun can burn the leaves.  Needs moist, well-drained, humus-rich soil.  Warm rainy season and dry cool season.  Plant will be dormant from late fall to late spring.  This is one of the last plants to emerge from dormancy in the subtropical garden.  Like all gingers, Siam Tulips are propagated by division of rhizomes.  
Flowers:   The inflorescence is comprised of large, showy bracts with tiny flowers emerging from the axil of each bract. The one-inch blooms are purple and white with red/gold markings.  The actual blooms are not as noticeable as the much showier bracts.  The inflorescence appears in varied hues of white, pink, or deep fuchsia, depending on cultivar, and will be  showy for months, throughout the entire growing season.
Uses: One of the most stunning members of the ginger family and a great choice for the subtropical shade garden.  Especially nice planted under oaks, pine trees, or palms.  Effective as a specimen in a mixed border or mass planting.  With long, stiff stems, Siam Tulips make an excellent, long-lasting cut flower.
Origin:  Native to Siam (Thailand), as its common name suggests, as well as other countries of Southeast Asia.  In Thailand, festivals are held every summer in honor of the wild-blooming "Dok Krachiao" that blanket the landscape with the return of the rains.




Siam tulips are show-stoppers in the summer garden.  It is not one of the more commonly grown perennials in Florida.  It is a mystery to me as to why they are not more popular.  They are pretty easy to grow and thrive in our heat and humidity.



Perhaps they are not more common because of their short growing season.  Florida gardeners can be a little spoiled when it comes to that year-round growing season.  But then again, caladiums have a similar dormancy period, and they are fairly popular.  Perhaps it is just that these are not highly available and are quite pricy when we do find them.



Regardless, every summer, I find myself wishing I had more of these.  I currently have five clumps that are large enough to divide.  I just need more room to place them!



I have two varieties: a deep-fuchsia and a pink-tinged white.  Wish I knew the name of these cultivars, but they don't sell them with names in my neck of the woods.  I find myself tempted on a daily basis to cut the scapes and create flower arrangements with them.  But I must leave my bouquets in the garden...for a little while longer, anyway.



I really could photograph these blooms all day long.  Here is the aerial view of a bloom.  Don't you think the bracts look like petals of a flower?  Just stunning!  



But it is the elevation view that shows clearly why this ginger has been dubbed the "Siam Tulip."  Isn't it great to be able to grow "tulips" in Florida?!!

  1. Your siam tulips are really beautiful, especially they are in big clumps. This is my second year to have siam tulips, and the clump is still not big. I have both colors you have, and another light pink one. I wish I can have more partial shade area to grow more of these. I bet the look superior in a flower arrangement, no wonder you tempted to do so :)

  2. @ Ami: Thanks, Ami. I too wish I had more space with the ideal growing conditions. I would plant a whole lot more of these. Oh, well, maybe when I expand the shady gardens in the future. And yes, they do make lovely bouquets...I used them that way last year. Just another reason why it would be nice to have more plants. I could cut just one or two stems from each clump and get a wondrous bouquet.

  3. Gorgeous. Mine have the burgundy mid-rib and are the bright pink. (The one time they bloomed) They aren't blooming this year. I have had them for two+ years now and divided them last year. Last year was their first time to bloom. The clump got huge and so I divided them thinking how lovely they would be in different spots this year. Maybe they need a season to settle in after dividing? I miss their blooms.

  4. I agree with you...I don't know why more people don't plant them. They are wonderful!

  6. @ NanaK: Hmm...that is exactly why I'm always afraid to divide plants I have less experience with. My oldest Siam Tulip clump is three years old and has bloomed every summer. But then again, it has never been divided. I think I'll divide just one plant per year, just in case they don't bloom for a while.

  7. @ Susan: They certainly should be in more Florida gardens.

  8. @ Chris: Don't know why they didn't bloom after division, but NanaK said the same thing about hers. Makes me afraid to divide mine. My other Curcumas are super-tough when it comes to division.
