Someone sent me seeds a few yrs ago & they have been coming up variegated. The flowers are cool (like balloon flowers) and suppossedly, white flies hate them & stay away. They drop seeds in same place every yr & just grow in spring (even thru my winters). Here's a pic of one that just came up in a potted cherimoya & is still growing fast. Sorry, you can't see the flowers very good, but I really like them. They can take draught & love sun & grow bushy - maybe 2 1/2'X2 1/2' or little more.
Still have some from fall '05 that will grow well now or next yr - plus fresh from this yr. (which may not grow till next yr) Email me for my addy to send SASE if you're interested.
