Haven't grown it yet. Seeds were easy to find:
http://www.kitazawaseed.com/seed_077-168.html
www.cherrygal.com has carried it but appears to be out of stock.
There is an interesting article/recipe at http://abissadacooks.blogspot.com/2010/01/dinner-molokhia.html

Here is a link that might be useful: Molokhia Seed

Would you like to trade some seed?
I have small packs of 100 seeds - broken down from a large package from Kitazawa seed co. They germinated well. I grew this before while living near the Mediterranean sea - it should do well for you in Florida. I am hoping it will do well here in So Cal - we have less summer humiditythan the city I used to live in and the Molokhia thrived there.
I'm interested in most things that your cannot find in the supermarket - asian cabbages, fall bloomers, winter veggies... tempt me :)

Grown it here (Edgewter) for the last couple of years. It grows great. Email me.

Growing it in So Cal - Los Angeles. Delicious!

This looks interesting. I've heard of it, but never tasted it. Can anyone tell me how it tastes compared to real spinach?

I find it a mild green with a faint minty flavor. It grows gangbusters from cuttings. Often at the plant sales esp the Rare Fruits.

Good in salads and on sandwiches. I made that recipe and found it ok. Perhaps I will try it again.

It grows fairly easily once established. Sometimes I have germination issues and cutworms. I found seeds at the farmer's market near me. The taste is mild spinach (especially after rainy weather) and good in salads.
