(lat. Canna indica, also known as: Saka siri, Indian shot, Kana)
Canna lily is one of my favorite plants. It's a native Caribbean and tropical American plant but with proper care can grow everywhere.
This perennial is very frost tender so if you live in hardiness zone 7 like I do the best way is getting bulbs out of the pots in the fall and planting them back in spring or collecting seeds and planting seeds after last frost.
It can grow from 90cm(36in) to 2.5m (8ft) with flowers that can bloom from late spring till mid fall(first frost) in many colors
I have canna that blooms in orange-red, but it can also come as red(the most common),gold, yellow or magenta.
As it is a tropical plant it needs a lot of water. The soil must be consistently moist, and it enjoys a lot of sun. Mine are always in front of the house where temperature in summer is around 40-50°C (104-122F) and with watering them every morning and evening they grow like mad.
Like I said before they can be grown from seeds. Seeds are placed in green balls that are on the flower. You can't miss them they look a lot like green chestnut cupules. All you have to do is let that cupules dry(they should be dark brown) and remove seeds.
Seeds are small,heavy and black. They can also be used as jewelry beads or in rattles, people even used them in old guns as ammunition.
I divide my Canna lilies from bulbs. In the fall I get them out of the pot, and just tear bulbs a part. As long as there is a bulb or part of it next year you will have new Canna.
This year to plant Cannas I had to remove my hyacinth from the pot.
So I got them out and placed them in smaller container. This way the bulbs will mature and they will bloom with a lots of small flowers next year.
You can see that we have now a full box of Canna bulbs. We got just one bulb few years ago and now we have no idea where to plant them all.
So this year we will plant 4 pots with them. I love them cause they grow very big and by the middle of the summer they cover the whole window. They are perfect for making shade in the room.
I have read in many places that each bulb needs around 60cm (23in) to grow, but I don't follow that. I place them as tight as I can. Over the years I've noticed that the less room they have the bigger they get. And I need them tall. If you want them to look like a bush with giant leaves then plant them with many room between. This way they will stay shorter but have many big leaves.
While I was planting Cannas I decided I should also plant gladiolus bulbs. So I planted them too, and noticed that there are a lots of small bulbs. So I collected them and planted them in a pot. If what I heard is true from little ones should grow big ones. Guess we'll see soon.
My tulips are blooming. Well at least one pot of them is...the other is still sleeping. Maybe soon they will bloom too.
Of course I couldn't take a picture without a big black but getting in the way. Nero decided he could catch some sun while I was working. I wish I could be like him sometimes, eat, bark a few times, play and sleep 18 hours a day.
