New Yellow Colossal 
<— Calendula 
In addition to being the biggest 
calendula in the world, Yellow 
Colossal is the most profuse bloom¬ 
ing of all large flowered varieties. 
The beautiful, clear, bright yellow 
flowers grow 4^2 in. across. 
The well-formed, bushy plants 
grow 18 in. high and are loaded 
with flowers so that it is most suit¬ 
able for use as a bedding variety. 
Showy in the garden and especially 
desirable for cutting. 
Yellow Colossal is bigger and 
better than Sunshine — the flowers 
are larger, more fully double, more 
compact and of better form; the 
outer petals are long, loose and 
gracefully curved. 
Pkt. (100 seeds) 250; 
225 seeds 500; 500 seeds $1.00. 
The first flower produced by the 
use of chemicals. Tetra is what is 
known as a Tetraploid Marigold. 
Colchicine, the powerful chemi¬ 
cal made from the fall crocus, 
was applied to Guinea Gold 
Marigold. It caused the dou¬ 
bling up of the cell contents and 
this new marigold consequently 
is extremely big and strong 
growing. It is a “Tetraploid.” 
Flowers are large, 4 in. across, 
deep golden orange, and freely 
borne on plants that are much 
more robust than other mari¬ 
golds. The main stems are ex¬ 
ceptionally thick and heavy; 
plants grow 2^ ft. tall and have 
the usual marigold odor. 
Its robust growth and heavy, 
dark green foliage make Tetra 
Marigold especially suited for 
borders and bedding. Tetra is 
a flower of most artistic form; 
nice for cutting. 
Pkt. (75 seeds) 250; 
175 seeds 500; 400 seeds $1.00.
