Iris tuberosa “Blue Jade”

Ooh! Ooh! If you find seeds, I want some too. One of my favorite “topics” of plants to grow are those with flowers in the cyan or teal part of the spectrum. They’re rarer than true blue flowers. A long time ago when the PBS list had some topic discussions, we went through all of the colors on the color wheel, and there was a small discussion of the few flowers that are teal. Luckily two of them are bulbs from the western Cape Province area of South Africa. So if you can grow bulbs from that area, you can try growing Lachenalia viridiflora and Ixia viridiflora. ‘Viridiflora’ in this case isn’t green. It’s a turquoise/teal/aquamarine color. And they’re stunning. (I had a pot completely full of Lachenalia viridiflora in full bloom one winter and it was so amazing to stare at. You just don’t see that color in nature very often at all.)

Anyway, Jane McGary mentioned that she knew of some Iris tuberosa that were teal in color, but I never found any pictures on the internet, and I’ve ordered various seeds that were supposed to have some bluish flowers, but none of them have been teal. She also mentioned that there was a teal gentian as well. But those aren’t bulbs.

BTW, even if I can’t grow them, I still want to see them in person. There is an absolutely stunning one, that is off-topic because it’s not a bulb, but if you’re offered the opportunity to see the Jade Vine (Strongylodon macrobotrys) in flower, take it. The flowers don’t look like they are real. Sadly, it is tropical and requires a lot of space to grow. Luckily, the Huntington Gardens has an amazing vine growing in their large conservatory greenhouse, and it blooms regularly.

(And in case anyone wants to know the others that I know about, there’s another small tropical called Ecbolium viride, as well as two Puyas, P. alpestris
and P. berteroniana. The two Puya will grow here, but they get very big and have very spiny leaf edges. Luckily the Huntington grows both of them outside in its famous cactus and succulent garden. Their flowers also look unreal. I would love to grow and see that Iris tuberosa ‘Blue Jade’, and see the gentian that Jane knows about because I don’t think it will grow here in Southern California.)
