You won't have to fly to Mars to get this delicious and seedless blue grape.  The Mars Grape 'Vitis Mars' is an average sized grape that grows in full clusters.  It is a vigorous grower and can even grow its first fruits early.  It has a good resistance to diseases like powdery mildew and black rot.  The Mars grapes have a tough skin that will easily separate from the flesh.  The flesh is very pulpy so would do well in desserts and eaten fresh.  They have a flavor similar to a Concord grape.

The height of the Mars grape vines can grow from 6 to 8 feet tall and 3 to 4 feet wide.  Grapes require moist, well-drained soil and lots of full sun.  They do need good support to grow on which can be trellises, arbors, fences to name a few.  They are best planted on the south side of a building or near a windbreak to block any strong winds.  They are hardy from zone 5 to zone 8.  Grape vines are considered ornamental due to their twisting, winding vines and the flower colors and occasional fall color.  Growing your own grapes can save you money at the grocery store and homegrown tend to be fresher and more tasty.
