Oncocyclus and Regelia Hybrids 
These vei'y beautiful Iris Species are among the most remarkable of all Irises on 
account of their delicacy of color, smooth texture, intricate veining and unique forms. No 
two of them bear any resemblance to each other. One of them, “Arenaria”, is a tiny min¬ 
iature for the rock garden; the others are all of average size and height. 
They are perfectly hardy in our coldest weather, but require the protection of a cold 
frame, not for protection from frost, but for protection from excessive moisture during the 
summer months, so that they can be covered and allowed to die down during the sum¬ 
mer after they have finished flowering, at which time they require a period of rest. This 
is accomplished by withholding all moisture during the summer by protection of a cold 
frame. Given this treatment they flower profusely in my gardens. 
Where only a few are grown the same results may be obtained by potting them, bury¬ 
ing the pots in the ground in the fall where they are left until flowering season. After 
they have finished flowering the pots may be lifted and put away to dry, keeping them 
dry all summer and burying the pots again the coming fall, or taking them out and re¬ 
planting them at that time. 
The best soil is a combination of sand and ordinary garden soil, with a liberal per¬ 
centage of peat mixed in, and some bone meal for fertilizer. 
ARENARIA —A tiny miniature Hungarian 
Species, that produces a shower of yellow 
and gold flowers, only 3 to 4 inches tall, 
the individual flowers lasting no longer 
than a day. although the plant continues 
to flower for several days. It is of course 
of special value for a pocket in the rock 
garden. Requires rich sandy soil. Hardy.
