Grafting Eggplant onto Devil Plant

Giant devil fig - Solanum chrysotrichum for eggplant grafting

Would you like to grow an eggplant tree, yes you heard right, a tree, that can produce dozens of eggplants, and not die down in winter?

Well, you can if you graft eggplants (or tomatoes) onto a perennial Devil Plant rootstock. In this article (which is probably one of the most comprehensive articles on the internet on the subject of grafting devil plants) we’ll explain how this is done.

Devil plants are used as a rootstock to graft onto because the plants are very vigorous, with a stronger root system, allowing the plant to support more fruit and tolerate diseases that affect the root system of eggplants and tomatoes. In a warm climate or in a greenhouse (or appropriate cover) in colder climates, the plants will produce eggplants year after year.

I’ve just completed a major update on one of Deep Green Permaculture’s most popular older articles, read the full revised article here on eggplant grafting



  1. Hi guys I just read your article on grafting eggplant or tomato’s onto devils root stock, I have seen bunnings stock them but always missed out on buying them, I wonder if they sell the Devils plant so I can graft my eggplants now ?


    1. Hi Peter, most of the grafted eggplants sold in nurseries are just grafted onto a second identical eggplant rootstock using an approach graft – that’s where you grow two plants side-by-side, scrape part of the side off the stem, tie them together, then when they’ve fused into one, the top of one plant is removed, leaving one plant with two identical roots. Unless it looks something like a graft on a taller thick spiky stem, or it says it’s grafted on a devil plant, then it’s just eggplant rootstock. I did see proper eggplants grafted on devil plants at CERES in Brunswick many years ago.


      1. One year on…. does anyone know if you can buy eggplant grafted onto devil plants. I am keen to get hold of one.


    1. That would depend on how warm your climate is, or if it’s in a greenhouse in cooler climates. If the grafts aren’t killed off by winter cold, the grafted tomatoes will produce year after year, and they will produce when the weather is warm enough, and when day length is also long enough.

      To grow tomatoes in winter, you would need to have the right location and perhaps a greenhouse. Winter days are longer if you live closer to the equator, and a greenhouse will boost the temperature.

      In Australia, in tropical Queensland, commercial growers do grow winter tomatoes in greenhouses to supply the national market over the colder months when tomatoes would normally be out of season.


      1. Thanks, Angelo. I do have a nice big greenhouse, but first of all I’m going to try it on a kangaroo apple in the ground. After that I’ll experiment with a seedling in a pot in the greenhouse.
