Moro and other oranges will be the slowest growing and smallest trees. Lemon will be somewhat taller and upright if you grow Lisbon or Eurica. Grapefruit will be much larger and grow faster, mostlikely almost twice the size. I have seen a 12 year old grapefruit big enough for me to climb up 6 feet in it (I'm 6'3" and almost 300 pounds) while the oldest washington navel, the origional which growes to this day in Riverside CA, is well over 100 year old and is still not that big.
My I also sugest a Dasiy and a Kinnow tangerine. They have very rich flavor, and are very juicy. Daisy can be ripe as early as Thanksgiving, depending on your area, and Kinnow will be much later, giving you a 5 to 6 month harvest season. They are very simular in shape and size to Eurica lemon so the 3 together can make an effective hedge with trees that are simuar size. All 3 are thorny. Moro is not very thorny at all.
My Moros are in their 4th year now, so I'm looking forward to some good pickin's soon!

My Moros are so vigorous that I control it by grafting other types of pigmented oranges on it. It is as vigorous as my navel and valencia. Also big canopy. Satsumas are the slowest grower in my yard. Even my Calamondins are faster growers than my satsumas. My satsuma is only about 7 ft tall, my calamondins are 16 ft tall, both are 5 years old. My moro is about 8 ft tall, and only 4 yrs old, if I hadn't grafted over it, it would have been 10 ft by now.
