This was a very easy vine to germinate and grow. I grew mine in a fairly big clay pot with some marigolds, in an area that does not get the strong afternoon sun. I started these seed in early March - it is now mid-June, and some seed pods are already dry. The vines grew about 4', which is really better than I had expected, since these were the first I grew in pots. I will grow some in ground, and measure those as well.

It was a very nice surprise in a packet of seeds purchased thru a small co-op here on Daves Garden. Actually, I was shocked to get the reversed tube on this particular plant. Don't know if any seeds will be formed, but will try to hand pollinate to ensure some seeds at least for next year.

The plants that I have grown have had colors that very closely resemble the pictures posted here,i.e., a sort of 'Chocolate Rose' yojiro(i.e.,with white rays or spokes) type of color,and a common name that more accurately reflects the actual color may be more realistic than the misleading 'Orange' color depicted on the Japanese packets.

Chachamaru means "Little Brown" in Japanese....it is not orange and it should not be called orange.

The name, translated by the person in Japan that I got them from, means:

"Cha means brown color, maru means...it is a kind of endearment for a man who is charming. We use maru, Davemaru, Stephenmaru, like this :) We call a man in affectionately, using for a man not for a woman."

So, what would that be? "Charming Brown" or perhaps "Lovely Brown" or "Sweet Brown" ?

I got these seeds in a trade with a person in Japan - they are from the Sakata company. I had 100% germination on them! Bugs and critters seem to really like these vines, though - much more than the 'standard' morning glories, so keeping them dusted, especially near the bottom, even after they are large, seems a must. I had several cut, even after they were vining up the fence. Never... read more

One of the most intresting colors of the Fuji (Spoked) series. Color rage is from a peachy coral to a deep orange, or brownish with white spokes. Fast to sprout and fast to set first blooms. A real eye catcher in the garden and the hummingbirds and butterflies don't miss it either.
