Oncocyclus Irises 
T HESE remarkable species are perfectly hardy to our coldest winter weather, but require the protection of a 
cold frame, so that they can be covered and allowed to die down after they have finished flowering, at which 
time they require a period of rest. This is accomplished by withholding all moisture throughout the entire 
summer by means of the 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 accomplished by potting them, burying the pots in the 
fall, where they are left until after flowering season; then the pots may be lifted and put away to dry. Or they 
may be dug up in July and stored in dry peat or dry sand for the summer and replanted in October. The best 
soil is a combination of sand and ordinary gaiden soil with a liberal percentage of peat mixed in and some bone 
meal for fertilizer.

Korolkowi 
Susiana 
Regelia Irises 
T HESE very beautiful species are among the most remark¬ 
able of all Irises, some for their delicacy of coloring 
and smooth texture, others for their intricate veining and 
unique form. They are not at all difficult to grow in a cold 
frame, given the same treatment as Oncocyclus Iris. They 
will well repay any special attention given them. They flower 
in Bayside in early May, before any of the Tall Bearded Iris. 
Korolkowi and Stolonifera are entirely unlike any other Iris. 
Arenaria —3 to 4 in. A tiny miniature Regelia Iris that is hardy 
outdoors, in a rough, stony, or very sandy, dry location. 
Attractive deep yellow flower that remains open for only 
a few hours.50 
Hoogiana —30 in. A native of Turkestan, notable for a won¬ 
derful smoothness of texture. Color very soft uniform sky- 
blue, without any markings.50 
Korolkowi —22 in. Another very interesting Species from Tur¬ 
kestan, in every respect the opposite of Hoogiana. Elongated 
flowers of creamy-white with intense blackish-maroon veins, 
giving a brown-and-white-striped effect. 1.00 
Stolonifera —30 in. An exceedingly handsome Iris of elongated 
form, with an indescribable blending of fawn and brown, with 
clear electric blue. 1-00
