BERKELEY HORTICULTURAL PERENNIALS 
ROCK PLANTS AND ALPINES 
PERENNIALS—“IT’S NOT A HOME UNTIL IT’S PLANTED”—with flow¬ 
ers, trees and shrubs. Our we’l grown perennials add that touch of color to the 
garden that is so essential to its fin ; shed appearance. If careful to cut back the 
old flowering stems, a succession of bloom may be had on many plants. Peren¬ 
nials are best planted before the first of May. 
ROCK AND ALPINE PLANTS — Our rock and alpine plants are grown in 
pots and may be planted at any time of the year with good success. We add 
many new varieties to our list each year and with the increasing interest in this 
class of plants, there is a wide range for their use, either in the rock garden, 
built for their particular use, or in the flower borders with other flowering 
plants, where they may show off to good advantage. 
OUR DISPLAY ROCK GARDEN—A large rock garden has just been com¬ 
pleted at our nursery where all these rock plants may be seen growing and 
flowering. You will find it to your interest to visit this garden during the year 
and note the wealth of bloom that exists all during the summer from early 
spring.
