There could be several reasons. One is the plants are likely tissue cultured and may have yet to outgrow all the chemicals used in the "stew" they were created in. Although the inflorescences look good they may still be malformed due to the process of tissue culture. Eventually they should out grow this. A possible solution is to buy tubers from another grower that has grown naturally in the ground. Caladiums are like Philodendron in they are unisexual and have imperfect flowers containing only one sex. The female flowers develop first but they are hidden inside the "globe" at the base of the inflorescence. On the first day the inflorescence opens the female flowers develop hidden inside this female floral chamber. These are fertile for only a single day. The next day the male flowers develop on the upper portion of the spadix and should produce pollen, which appears like a fluffy "fungus". In between the two, and still inside the female floral chamber can be found the sterile male flowers that produce the pheromones used to attract natural insect pollinators. The female flowers are receptive for a short period of time and the male flowers produce pollen for a limited period of time before the inflorescence collapses. If the female flowers are pollinated the female floral chamber will remain on the peduncle that supports the inflorescence and the berries and seeds will develop inside. In order to pollinate this species you must first collect the pollen once it appears and unless you have many inflorescences still developing and can use it right away put it into a sealed vial that also has desiccant in it to prevent the pollen from being destroyed by moisture. When you realize a new inflorescence is beginning to open mix the pollen with sterile water to create a thick mixture known as a slurry. Use an eyedropper to drip it into the female floral chamber. Before doing so place a piece of tape over the overlapping edges of the chamber to prevent it from dripping out too quickly. After about 15 minutes remove the tape and if you are lucky the female flowers may have been pollinated. My friend Julius Boos wrote a great article a few years ago explaining how both bisexual and unisexual inflorescences develop. You may want to read his article, which is illustrated before attempting to pollinate again. If there is simply no pollen being developed there is likely a reason that is causing this natural part of aroid reproduction to not occur. Without seeing the plants that may be difficult to determine but aroid pollination expert LariAnn Garner who often frequents this site may have a better answer. The link below is where you can read Julius article. Steve Here is a link that might be useful: Aroid pollination

Being that this is my first year growing tomatoes, my experience is rather minimal. For my first attempt, I went with seeds of Roma VF and Martha Stewart Sweetie (probably the only thing I have ever gotten with her name on it. Ever.), both were purchased from my local HD. I find both to be quite enjoyable, but the Sweeties are definitely sweeter. They're also smaller. Neither variety is big by any stretch, I would not be able to use them on sandwiches, but they have been great for plucking and eating while working in the yard. I keep telling myself I'm going to try making my own spaghetti sauce out of the romas, but have yet to light a fire under my butt in that little endeavor. Next year I will be growing one Sweetie, one Roma and one... bigger variety as I would really like to have some good sandwich/burger tomatoes. I was thinking of trying Better Boys, but after Tradition's comment, I might try something else.

Hi I got one of those when we bought the house in 79 but i had to go out and look to see if i had red ribs I do Since it's at least 35 yo and still growing must not be too important?? There are several varieties and hybrids of these with slightly different habits . Mine for example is around 8 feet tall while the neighbors has remained under 4 Theirs flowers twice as much as mine though it's patially shaded .?? They seem very easy to grow EXCEPT for being underwater they hate that lol Yours looks like the "standard " type .judging from the flowers. There are hybrids within reginae that are pure yellow as well as white and not to overlook "juncea) which has identical flowers BUT leaves are tube shaped . There are also closely related types thast have MUCH different habits Relax and enjoy them . Seem to be immune from bugs tolerate some cold ,even drought but don't try them as a water plantlol gary

"Although I am in Southern California, being close to the ocean, the weather here doesn't really start warming up with sunny warm days and nights above the low/mid 50's until mid May" You must have a micro climate and not actually 10b? I'm in SC, 7b and normally we are above 50's in mid April. Funky weather and a lot of rain has kept it cooler this year though. The toms that I put in my homemade "earth buckets" early March are already blooming and growing like crazy. My in ground toms are kinda sitting there. Due to the rain and cool nights. Great looking toms! I have a quarter that I'm willing to bet that the potted ones produce first! I had ripe ones in May last year but I babied them and planted earlier. I would bring them inside at night when the temps were going to be near or below 50.
