ALL-SEASON— Species and Botanical Varieties —Page 23 
No general notes apply to this group, as each variety 
or species is a definite individual. Vary in height from 
3 to 20 inches. Periods of bloom range from last week 
of March thru last week of May. Exceptionally well 
suited to rock garden culture. Include many rare items 
of unusual interest and charm. 
Note: Blooming periods are based on the Northeastern part of U.S., but the same 
sequence will follow in any part of the country.
