Re: Naranjilla (Solanum quitoense)
I have grown this plant a few times, in the S.F. Bay area; I find it a frustrating species. The plant is super thirsty and prone to pests ( esp. spidermites). When it is happy it can grow quickly and have stunningly gorgeous leaves. When it isn't happy, it can look like death is certain, only to rebound and then decline, seemingly at random. Maybe they are prone to viruses...
When you do get fruit it can be fantastically good, or kind of weird and not worth eating.
Some strains have wicked thorns, others are soft, fuzzy, and charming.
I would be very interested to hear from people who have success with this.
