Iris Garden
The Iris Garden holds a large number of iris cultivars 514 from 6 species.  The iris bloom primarily in May and June with the most common being the tall bearded iris (Iris germanica) and Siberian iris (Iris siberica).  The bearded iris come in all colors except a true red or orange and they range from dwarfs only a few inches high to those with stalks up to 3 feet.  The non-bearded iris (Siberian and Japanese) have color ranges from white and light yellows to blues, purples and some reddish tones.  The Siberian iris give a nice show in the garden throughout the season as the foliage stands up throughout the summer.  The Japanese iris (Iris japonica) have large flat flowers in a range of colors but mostly white, blue and purple.  They can be quite spectacular in bloom.  We have 516 specimens in the collection.
