What season are you growing these Calibrachoa hybrids in? Are your hanging baskets covered by a roof or any other structure? Etc, it is possible but unfortunately they just aren't weather proof for most garden situations, even containers. No matter where you live. They dont like to be crowded by other plants as air circulation is of life threatening importance because of the plethora of moulds and fungus and root pathogens they are susceptible to. So cannot even be used in mixed plantings, surely they will die as the other plants cannot survive without regular water. Those marketing these plants have been changing the goal posts for consumers ever since these things first appeared. The perfect, easy, self cleaning, heat loving garden plant tough as boots, is suddenly now only for containers with complete protection, perfect PH, in temperate climates with no rain and clear blue skies indefinitely and vitally timed applications of chemical ..........of course consumers have been buying them by the "millions" because of the hype and are having disastrous results. It's fraud plain and simple. We wouldn't buy fruit that you couldn't eat and it's in fact illegal to sell fruit in many countries that wont ripen once picked or is an unsatisfactory cultivar. Consumers don't seem to get the same protection with plants and producers can say anything. What is interesting is to read the sites on the net for producers, mostly PDF files, they explain how to grow on the plugs to sell to retailers. It's not easy! Not at all. Some even say as much. They are susceptible to almost every pathogen known to infect plants in production. Growers have to rely heavily on chemical solutions many which are not (even if they were environmentally friendly) available to home growers. They aren't however environmentally friendly and it's irresponsible to create a demand for their usage. Even if we all were sloshing nasty chemicals all over the place the plants are again critically sensitive to dosage, type and timing of application. Without a doubt it is true that the production of bedding plants generally are a nightmare of chemical pollution already. Treated as throw away plants after and the environmental footprint left behind is completely unacceptable. Without diminishing your success you might just have benefited from recent heavy or specific grower applications of chemicals, hormones etc long enough to get some results in a very protected site. I've even resorted to umbrellas to keep them dry, they just cannot take average normal wet conditions, whether from passing rain or watering. Establishing them in the ground is impossible. I've had only very limited success using almost pure acidic sand. Whatever you do even in containers, with the right PH If you plant three two will die almost immediately. One might or might not persist but never ever the "all Spring and Summer long" rubbish they tell consumers. Here's the thing, these are sold and bred as bedding and container plants, the things you stick in anywhere in full sun for instant colour that flower themselves to death with minimal care. However they are in fact a highly specialised plant to grow, best suited for green house conditions, however the effort for such a short lived woody plant makes that not terribly rewarding either. They hate disturbance as well so transplanting is almost impossible even from pot to container. These are hybrids of many species of Calibrachoa (lovely name) and as such one would expect some kind of almost manic hybrid vigour. Unfortunately it seems the aggregate of the species is even more difficult than the individual species to grow as a result of all this breeder effort.

An unaided East window in the Mid-Atlantic will keep a Dend alive till about December. By then its decline will be noticeable and it will be dead by Valentine's Day. Dends do not forgive less than stellar light supplies, light and how to get it should be your main concern not how wet or not the medium looks. Sorry to be terse, limited time. It looks happy because it takes time, sometimes a long time for the problems to show but it is not happy. Since it is not in bloom the best thing you can do for your dend is to get it outdoors while you work on a light rig. Don't just put it on a south balcony in full sun either. Give it several days of an hour or so each day, gradually increasing the time. Better still is to have a translucent awning or lath or some other 50% shade structure over the dend so that at no time is it ever in full sun. If you go that route the duration must be decent. An hour or two won't cut it. 4, 6 more, thats getting there. That's about how they grow in nature, way up high, light shade, several hours (7+) each day (consistency) in areas with 300+ sunny days/yr. H

Can you give us more info on the "full sun to full shade" issue? Full sun would be 6 or more hours of direct sunlight, Partial sun/shade is 3-6 hours of direct sunlight, and full shade is 3 or less hours of direct sunlight per day. Here is a link that might be useful: What Does Full Sun Mean?

It's a Costus. Looks like some form of C. scaber, but the names keep changing, so I'm not 100% sure. Most Costus can be grown from stem cuttings. They're fairly adaptable as to light conditions, but probably would not be happy in dry, sandy soil. If you could mix in some compost or other organic matter as you plant, and keep it well-watered, it would help. Here is a link that might be useful: Costus scaber
