It seems that there are more and more colors and varieties available at stores.
I have been thinking its reason and now I think I have an answer.
My answer is it's because of "Marriage (Hybrid by Pollination)!"
So I just tried...hoping "Orange" + "White" can be something.
If my answer is correct.....there will be seeds of new color.
Pollination may be not so easy, but I'll see what will happen.
By the way, we have received donations of so many kinds of plants and pots from N. Family through our friend Lisa-chan. Arigato Gozaimashita! I will take good care of plants and will increase more for helping the temple's funding.
