Nativesun,

I have 2 Grumichama been in ground 2 years but no fruit yet.  

How is the taste of cherry of rio grande and grumichama? I love bing cherries and luckily they are easily available.

Of coarse everyone's taste preference are different but I found out that if you let the CotRG get really ripe, almost black in color, they are really good. People who do not let them get ripe will say they are inferior to grumichama but I prefer CotRG and plan on purchasing more. They are very inferior to Bing Cherries, nothing beats the real cherry and you will find nothing tropical that will.

I do miss cherries......well not miss exactly as I had them for lunch but the bings they bring in from Washington really pale to those from the northeast and picked at the peak.   Can't have everything I guess.  Cherries and concord grapes fresh I do miss.  The concords I get around with Nesbitt muscadines which taste identical, they are ripening now.  The cherries though are much tougher to fine a stand in. 

Like Wayne said, they are "cherry-like"  and do not compare to a "real" cherry , but IMO have a bit of a berry undertone and I find them delicious. Plus they grow pretty well here -- I do keep them potted up so I can bring them inside when we have a hard freeze.  It took between 3-5 years for any of these to fruit for me.  

Im trying to push my limits here in N. Florida with some of the tropicals .... have added Avocado, Carambola, Sugar Apple, Guava, Papaya and Lychee and the've all survived and fruited. The guava actually took the cold this year (I have 'em in-ground) the rest I have in large containers.

One thing about all of these is that they are just really, really beautiful small trees
