The reddish may be related to how the stored forms of pre-active chlorophyll gradually become active and green in addition to the presence of reddish-purple pigments that are usually an indication of flower color and increased health.

The cotyledons are more than likely going to turn green as they are exposed to increased light.

The hypocotyl pigmentation will likely remain pigmented and (as you thought) may indicate that the plant may produce darker colored flowers.

Please do a followup on that particularly reddish seedling so that we can all enjoy learning what changes it may go through and what the matured plant produces.

P.S. - What climate zone are you in (if you don't mind me asking)...(?)

Thank you for the response!
- Of the seedlings I have so far, all of the ones from "pale" seeds are bright green.
- The four heavenly blue (darker blue flower) seeds are green with some faint purple veining in the leaves.
- 2 of my purpureas are green, while I now have 2 purpureas like the one pictured above.

I will definitely post a followup when the plants grow and produce flowers. I'm very curious to see if darker seed leaves mean darker flowers later on.

PS: I'm in zone 8.

Hi MandyRose9,

I'm so happy to see other persons posting their morning glory images.

Your seedlings look very happy and healthy. The red cotyledons on the I. purpurea should become green as they unfold and extend to take in the available light.

What variety is it?

MandyRose - You asked :

"I'm very curious to see if darker seed leaves mean darker flowers later on. "

There are white flowered I.purpurea that have black seeds and there are light seeded strains of I.nil that produce dark blue in the flowers ...

The answer is usually but not always.

best,

Ron
