Oh My Roselle: Growing and Using This Beautiful Plant

Roselle is a beautiful, fast-growing type of hibiscus plant that earns its keep in the garden. We grow it for the deep red calyces,

which can be used fresh or dried for teas, syrups, and other kitchen projects. It’s one of those plants that’s both useful and lovely, and once you grow it, you’ll wonder why you didn’t sooner.

Roselle has a long history of traditional use, especially for supporting digestion, hydration, and overall wellness, and it’s commonly enjoyed as a nourishing herbal tea. It’s often associated with antioxidant properties and is traditionally used to support heart health, including helping to maintain healthy blood pressure levels.

We have made ROSELLE JAM the last several years for Thanksgiving and Christmas cookies and everyone simply loves it. It is an easy recipe:

4 cups of fresh roselle calyces
1/2 cup – 1 cup of pure cane sugar (based on taste)
1 cup of water
2 tablespoons of citrus juice (we use limequat but you could use lime, lemon, orange…)

Instructions

1. Pull the red leafy parts off the calyces. You are trying to remove the inner seed pod. Wash them thoroughly.
2. In a saucepan, combine water & roselle. Stir and bring to a boil over medium heat. Once boiling start, decrease temp and simmer for 15-20 minutes until calyces soften and release their color. You will know it when you see it.
3. After simmering, use a potato masher or immersion blender to puree the mixture for a smoother texture. Stir in sugar and juice and bring to a boil again until sugar is completely dissolved.
4. Add a tablespoon of pectin here if you want your jam thicker. I have never used pectin in this recipe.
5. Check for thickness and continue cooking until it is how you like it. Once you have your desired consistency, pour into sterilized jars. At this point, you can water-bath can them for 10 minutes for half-pint or pint jars (adjust for altitude above 1000 feet) or you can simply freeze the jam! I have done both things and, honestly, it tastes the same either way!

But now, we are trying something different. A ROSELLE JUICE if you will.

Sam has historically had high blood pressure and now that I am at that age of a woman’s life where everything decides to shut down and go haywire, my blood pressure has been a little elevated as well. We decided to put the blood pressure claims to the test.

1. I took 4 pounds of frozen roselle calyces and juiced them in my steam juicer.
2. When the juice was finished, I had a half gallon of liquid. I tossed the spent roselle into the compost bin and put the juice on the stove in a dutch oven and brought it to a boil, then reduced temp to a simmer.
3. When the juice had reduced by about 25%, I added 1 cup of organic pure cane sugar and 1 tablespoon of cinnamon.
4. Stirred to combine completely and then transferred it into a clean half gallon mason jar and refrigerated.

Here is where it gets interesting! This is what WE are doing. I am not saying YOU should do this.

For the first two days, we each drank 1/4 cup at noon. we checked our blood pressures before we started and then each night at the same time to monitor. After the first two days, we increased to 1/2 cup each day at noon. Finally, after we finish our first week, we will go to 1 cup everyday at noon. We are currently 3 days in. So, check back and I will let you know if we have any blood pressure changes.

Here are the key things for US:

1. Sam is not stopping his BP meds.
2. We will report any significant changes to our doctors.
3. We chose noon because I didn’t want Sam driving to work right after taking the first dose in case he had a reaction. Noon felt like a safe time and it just stuck.
4. We are expecting to see some movement within the first week and better changes after two weeks.
5. We will be completely transparent with you. If it works, we will say so. If it doesn’t, we will say so.
6. Just because it works for some does not mean it will work for everyone.

FIVE FAST FACTS:

About Growing Roselle

• Roselle is a heat-loving plant that thrives in warm weather and needs a long growing season.

• It grows quickly and can reach 5–7 feet tall, so give it plenty of space.

• Full sun produces the best growth and the deepest red calyces.

• Roselle is fairly drought-tolerant once established but grows best with regular watering.

• Calyces are harvested in late summer to early fall, after the flowers drop and the seed pods swell.

About Using Roselle

• Brew it into a bright, tart herbal tea, either fresh or dried.

• Simmer the calyces into syrup for drinks, desserts, or drizzling.

• Make jelly or jam with its naturally pectin-rich calyces.

• Use it to flavor vinegar, shrubs, or simple syrups for the pantry.

• Dry it for later use so you can enjoy roselle long after the garden season ends.
