I live in Plant City,FL. I just happened to notice these growing in my yard. Every year they bloom all over the yard. Theyre such beautiful flowers. Ppl will randomly stop by to ask what they are. I'm glad I was able to find out what to tell them now. Shocked that they are poisonous. I'll have to make sure my kids stay away from them.

Beautiful flower, very dangerous. Would not have around young children. Nearly lost out pet dog due to allergic reaction to her fur touching the flowers. Be very aware.

Where I live 30 km north of Durban, South Africa Scadoxus multiflorus subsp. katherinae is found growing naturally in shallow nutrient poor water in coastal swamp forest. I have had very good results growing plants both indoors as well as outdoors from seed which I collected in the wild. The seeds were planted in pots filled with pure fine sand which were placed in large deep drip trays that I keep filled with water. As the plants have outgrown their pots I have moved them into larger pots with larger drip trays. I feed the plants on a regular basis with a variety of liquid fertilisers both organic as well as inorganic. Every so often I empty out the water from the drip tray and flush out the pots with fresh water. A word of warning do not try growing your plants in water if they are potte... read more

Amazing flower! Looks like exploding wireworks! Foliage is also nice after flowers fade. I have mine in pots so they can be moved to a shadier spot to prolong the blooms in the summer and to a dry spot for the winter. I have successfully started babies from seed. (I LOVE, LOVE, LOVE, free plants!!) I waited until the seed "berries" turned black, picked them off the plant, removed the outer skin, let them dry a day or so, planted them in potting soil, and waited a couple of weeks. (4 out of 10 seeds sprouted) They are about 3-4 inches tall so far - with a long way to go. Scadoxus is surprisingly hardy in Orlando's hot/dry conditions and take a fair amount of abuse (cramped pots, infrequent watering).
