The Echium wildpretii, aka the Tower of Jewels, is one of the coolest plants we’ve grown in the garden. Can’t say for certain, but believe we planted it back in Jan 2010. You can see an old skool picture of it from a post a year and a half ago (1st pic, left hand side).
Echium wildpretii is a biennial monocarpic plant native to the Canary Islands. We started ours from a four inch pot. During the first year it forms a short 2-3 foot stalk of leaves in a rosette pattern. Below is our baby with about a years worth of development.
During its second season of spring growth, it starts to pop out one massive flower which can reach 3-9 feet tall. Our flower spike lurked out last March. The next couple of pics show its progress.
April 2: the excitement builds and it bloomed in time for April’s Bloom Day.
Three weeks later, a flush of flowers began filling in…and two more small flower spikes shot out from the bottom of the stem.
Just a week later, the budding was nearly complete. I would have to call May 7 the day it peaked (see 1st pic).
…3 more weeks and this puppy was about spent. Well, it’s monocarpic thus it’s not coming back so…it was time to dead head it.
We are surprised how well it did in a container. We thought for certain that the roots would be bolting out the bottom of the wooden box it was planted it in. Turned out that everything was well contained inside the planter.
Oh, here’s a tip if you want to balance an Echium wildpretii on your head. The freshly cut stem was super slimy. So instead of resting it on your chin where it easily slips off…try balancing it on your lower set of teeth.
Today, he’s resting against the fence, pining for the fjords. There’s a ton of pin head sized seeds attached to the flower stalk. We’re gonna try collecting some seeds to see if we can get any of them to germinate. Any suggestions how long we need to let those seeds sit before trying to sow them?

When in doubt, sow some now, and sow some later. The only Echium that I have experience with is Echium vulgare. With that one, the “now” seeds produce babies in the fall, that bloom next year. I’ve given away seeds that didn’t get planted for over a year, and they still germinated. E. wildpretii – ????

Ahhh I love this tribe and grow many of them.,..I must say though you were a little hasty in cutting off the stem! The seeds may well be imature..AND the dead flower stem is great when it is completely dead!

I’m not sure which impressed me more, the plant in bloom or the balancing act.
Sorry can’t help with the seeds authoritatively. One of my books talks about its propagation through seeds but did not expound on the actual seed collection.

A garden buddy tells me it’s easy–too easy as a matter of fact. Just leave it where it is and your garden will be wall-to-wall Echium by next spring.

You won’t believe what I did. Well I ordered one if these beauties from Annie’s Annuals. I received it last week and took it out of the box and put it in a pot but with no extra dirt. I did water it. Then I forgot! Eeeekkkkk! Today I find it shriveling. So I quick throw water on it and put it in a bigger pot with dirt! Lots of water. I went out tonight and looked with my flashlight and I think the center is still ok and will come back but I lost the outer leaves. What a dufus!

I bet if you keep it hydrated it will work past its near death experience.

Mine flowered magnificently last spring. I harvested the seeds and planted some in pots and they came up almost right away. They are doing great and I am ready to put them in the ground. My hope is to start more next year so that I can get an every-year thing going with their 2 year cycle. I won’t have flowers this year, but maybe starting next year I can keep them going.
Enjoyed your post.

I think we planted one more last year that should flower again, and two more this past summer. Crossing my fingers.

Hi there – writing to you from the great white north. After seeing your site, I am inspired to order seeds for this beauty and attempting (along with my dad) to grow up here. Fingers crossed and please keep posting about the neat plants that you grow.
