Perhaps the Christmas plant I enjoy most is Solanum pseudocapsicum, with its fanciful mosaic of green, orange and red marble-sized fruit. Just now this Jerusalem/Christmas/Winter-Cherry (its three common names) is the shining star of my holiday window garden, in association with red poinsettias, white narcissus, and pink kalanchoe.
I can tell you that pseudocapsicum, if carefully treated, is good for a long, merry life. Grown in a cool but sunny place it will not drop its fruit until the end of February or early March. Leaves will fall then, too, indicating the cycle of rest has started.
At this point a strict haircut is necessary. Prune each branch back to two eyes or buds (you can feel these little bumps along the stems), and bring the plant to an even colder place, which, for me, means the east window in an unheated spare bedroom. Temperatures around 40-45 degrees, and full light is the goal. Water only sparingly — certainly not more than twice a month.
When new growth appears in late spring, increase water, and begin feeding with a high-phosphorous formula. Then bring the plant outdoors to semi-shade. All through the outdoor months provide plenty of water and food, for the plant is preparing its bright crop of fruit for your next winter’s pleasure.
Incidentally, pseudocapsicum’s cherries are not for human consumption. They are considered poisonous to all but the birds, who scatter the seeds in more temperate zones than mine.

Kevin, I buy a Christmas Cherry every December, but discard it in January. I don't have a really cold place to keep it for the long haul.
Samantha says
I remember buying this gorgeous plant once, but all the “cherries” fell off before Christmas! I think my house is just too hot and dry.
Kevin Lee Jacobs says
Gardenlady – Sounds like a good plan!
Samantha – Yes, coolness is the key to success with the pseudocapsicum. Stick to kalanchoe — neither heat nor low humidity troubles it.
Gregory says
Like Gardenlady, I buy the Jerusalem cherry plant every December, and then toss it when the fruit falls. But I've never had a problem with the fruit falling before late January, probably because I keep the plant on a humidifying tray of pebbles and water. It's a great plant, even for temporary enjoyment.
James says
Beautiful plant. I'll have to get one, even if its for the short-run.
Kevin Lee Jacobs says
James – do get a Christmas Cherry. It is far more interesting, and less common, than a poinsettia. But I like poinsettias too!
Victoria says
I liked the look of this plant so I researched it to see if it would grow where I live. I was somewhat horrified to discover that the fruit is poisonous to both humans and pets (per the North Carolina State University College of Agriculture & Life Sciences https://plants.ces.ncsu.edu/plants/solanum-pseudocapsicum/ ). PLEASE add this information to your article. I have a cat that nibbles on any plant within reach. Other viewers may have small children or pets and this information would be essential for them. On the other hand, I’m loving your blog and will be lost in the one about your home renovation for quite some time. It is BEAUTIFUL!!
