I grew Madras radishes a few years ago, which are podded radishes much like Rat Tail, but smaller. Podded radishes are certainly a novelty. The flavor was very mild, and thereby a little disappointing. Milder than regular red radish bulbs. Could almost just as well have been snacking on green beans. The Madras pods came gradually, so every week you might get ten or so off of one plant. I wasn't impressed enough to grow them again. They are supposed to thrive in hot weather, and while I have very hot weather, they didn't appear to really enjoy it that much.

It's a radish plant grown only for the seed pods, not to pull for the root. I think it is fun to grow. I like the pods but only as a snack, I pick off a few pods and eat them immediately. Mild radish taste with a little spice that kicks in when you chew them up. Pods are best younger when the seeds start to form, once they grow full length they are tough.

The plants can be tremendously productive if you keep picking them, and if the plant stays alive. They gradually grow pods over time. I've had over 100 pods from a plant, way more than I can eat. You don't need to grow more than 3 plants IMO, very productive. Sometimes the plant continues to grow new branches all summer,.

I plant them more than a foot apart, the tops get floppy eventually and do not grow in a tidy fashion. I try to support them some. Start out as a nice looking plant with flowers that attract pollinators, but gets rather messy after a couple months. You can start them in cooler weather, but the plants flower and pods grow in warm weather.

I've not tried the newest Baker Creek rattail, this is different than the one they had a few years ago. I've had good success with the Burpee 'Dragon's Tail'

Since I am going to have seeds I will go ahead and grow them. @robert567 thank you for such a detailed answer. I just looked up Burpees Dragon Tail and that does sound interesting too. Looking forward to it.

Hi @robert567! I placed an order with Burpee so I got a pack of 'Dragon Tail'. I will grow one each of Red Rat Tail and Dragon Tail. There will be so many seeds left over. Do you know if these have reasonable viability? They will be usable next year?

Radish seeds stay viable quite well, so you could use them for 5 years or so, more or less.

Not really sure how different those rat tail seeds for Baker Creek and Burpee will be, they may be almost the same... or not.
