Roselle, Rosellea, Florida Cranberry, Red Sorrel, or Jamaica Sorrel:
This tropical perennial is grown annually in temperate climates as a medicinal, nutritional, & ornamental plant. Serve fresh red calyxes in cocktails or jellies flavored like cranberries. Dried calyxes are infused for tea high in vitamin-C. Stir-fry young, edible leaves. Seeds are roasted & ground into flour. Forms an erect, busy herbaceous shrub up to 7 feet tall. Prune back to maximize flowering & harvest tender calyxes before they dry out
Roselle forms an erect, bushy herbaceous shrub up to 7 feet tall. Roselle is best planted early in the spring for maximum calyx harvest so you have a mature plant when it is triggered to flower as the daylight shortens in the fall season*. Prune back growth to create a bushy form, maximize flowering, and harvest tender calyxes before they dry out.

GROWING INSTRUCTIONS AND IMPORTANT INFORMATION:
Thank you for supporting our seed shop! To ensure germination success and get the best start with your seeds follow the recommended germination process and use the suggested methods. Our high germination rates can only be achieved using the methods shared below. Seed The Stars can not take responsibility for germination issues using other methods and materials.*
Store seeds in a cool dark place and use them within one year of purchase to maintain viability and high germination rates.
IMPORTANT PRE GERMINATION NOTES:
*Some seeds require soaking or scarification prior to germination. Soaking overnight or up to 24 hours helps to jump start the germination process for seeds with a hard seed coat while scarification involves gently scratching the seed coat to allow water to penetrate and hydrate the embryo.
* Some seeds like lettuce and certain flowers require light for germination. Please check the item listing for this information.
*Certain beans and peas have the ability to form a symbiotic relationship with Rhizobium bacteria to form root nodules that “fix” atmospheric nitrogen making it a great addition for your soil ecosystem. Seeds can be treated with a soil inoculant that contains the Rhizobium bacteria prior to planting to ensure that the beneficial bacteria is present. These inoculants can be purchased online or at some garden stores.
WHEN TO GROW:
- To figure out the best time to start your seeds first locate the days to maturity located in the item description or photo with Seed specifications in our Shop.
- Research your average first frost date(in the fall) and subtract the amount of days the seeds take to grow to maturity that you found listed on the packet.
If you still have adequate time before that first frost date and provide the ideal growing conditions you will likely have a chance at a successful harvest this season.
- To get a head start on your garden you can start seeds indoors 6- 8 weeks before your last frost date if providing the correct temperature, light, and properly sized containers.
STEPS TO GERMINATION:
1. Check the seed packet and click “Read More” under the ETSY item listing for specific instructions and seed specifications.
2. Choose a proper sized container for your seeds. Most seeds should be started in containers such as seeding flats and pots up to 4- 6 inches to better control early growing conditions.
3. Fill containers with consistently moist (not soaked), well draining, and sterile soilless seed starting media. Heavy and poor draining soils can inhibit germination and reusing old soil can transfer organisms or plant diseases that can harm a seedling. We DO NOT recommend peat pods/discs or pots since they tend to wick moisture away from the media.
4. Create a small depression in your media and sow a few seeds at the depth recommended on the seed packet. A good guideline is that most seeds should be sown as deep as the seed is wide.
5. Lightly cover the seeds with media and water them in, make a note for the day of seeding.
*Keep the media consistently moist with a gentle spray or bottom-water containers to keep seeds at the same depth that it was sown. Place the pot/flat in an area that can maintain a temperature range close to the optimal germination temperature on the seed packet. Be careful not to overwater which can cause fungal growth, media compaction, and lead to rot.
*Germination time will vary depending on the environmental temperature. Starting seeds on a germination mat, or an environment indoors where temperature can be better maintained will speed up the germination process.
*Once germination occurs, place your container in a protected area with adequate filtered sunlight and thin each pot/cell to have only one seedling per hole. If you need to continue to grow your seedlings indoors due to outside temperatures being too cold and variable, we highly recommend using grow lights directly above seedlings to prevent leggy plants.
TRANSPLANTING/POTTING UP:
When seedlings have a second set of “true leaves” and have developed a root ball that stays intact when gently removing it from the container they are ready to be gently potted up or transplanted.
“Harden off” the young plants by gradually extending their time in sunlight and the natural elements that they will experience when planted out, therefore they are less likely to go into shock. Once they have acclimated, transplant them out to the garden or a new container and water deeply for the first three days.
If potting up to a larger container, use a mix of potting soil, compost, and something like perlite to create space and good drainage. Plant the seedling at soil level in the new container and water well.
When transplanting into the garden you can add a little compost in the planting hole when transplanting, mixing in with the soil in your garden bed. Plant at soil level in the garden, unless planting tomatoes which can be buried deeply. Top mulch around your plants, keeping compost away from the stem in pots or in the garden with a 1 to 2 inch layer of compost and reapply throughout the growing season. Water deeply for the first 3 days and then when the plant is established, allow the soil to dry out in between watering - watering the soil rather than the leaves in the mornings.
FERTILIZER & AMMENDMENTS:
We fertilize and maintain our plants using organic methods: fish fertilizer, worm castings, compost, Kelp, and OMRI list organic granular fertilizer made of poultry manure.
HARVEST:
Harvest Calyxes when large, tender, and plump and before they turn brittle and brown. Remove seed pod from Calyxes before storing and using in recipes. Calyxes will stay fresh for about a week after picking, can be frozen, or dehydrated. Roselle contains a high level of pectin so calyxes and seeds can be used to make your own jam!
Roselle leaves are edible at any time. Simple harvest by pinching or sniping with scissors and use for flavoring beverages, adding to salads, or whatever other recipe you would like to have a tangy addition.
SEED SAVING:
Some plants cross easily while others self pollinate before there is a chance of crossing so if you are interested in saving seeds, we recommend you do a quick search on each species. If saving seed for the next growing season and you would like your next season plants to grow true to type make sure that you are only growing one variety of the same species or isolate your plants through distance/timing/netting to control cross pollination.
Seeds are ready to harvest when Roselle seeds are mature, brown, brittle, and light weight -you can shake your Roselle and hear the seeds rattling inside. Each seed pod has multiple compartments that contain seeds when broken open.
PEST & DISEASE:
Root Knot nematodes are a common pest. Use proper crop rotation and build a healthy soil ecosystem to aid in prevention. Mealybugs and aphids can be controlled by blasting off plants with heavy streams of water and making a DIY vegetable oil & CASTILE soap sprays. Only spray in the later afternoon early evening so the sun won't scald the leaves Roselle is sensitive to temperatures below 40 degrees.
