Hoya brevialata is a great Hoya that almost made my 10 Best Hoyas to Keep in the North List.  The only reason that it missed the list is that it can be a bit temperamental for the first year or so.  Once established it is a relatively easy to grow plant that will regularly reward you with many blooms.  It is also an easy plant to find in the big box stores in the summer through out much of the U.S.  Care is simple: Let it dry out between waterings and give it as much light as you can – Southern exposure is great.  There are no special humidity requirements for this one.
