THEY’RE HERE! 
RUST RESISTANT SNAPDRAGONS 
At last these beautiful flowers can be enjoyed in your 
garden. Modern scientific breeding methods eliminates the 
pernicious rust disease from these beautiful flowers. 
One problem which has confronted the seedsman, nurseryman, 
home-gardener, and flower-lover for many years, is that of producing 
Snapdragons which will not become infested with the dreaded Snap¬ 
dragons dust. How often has one had the experience of planting Snap¬ 
dragons of a choice strain with much diligence and painstaking care, 
only to see all of them become severely infected with rust. The final 
outcome is only too well known. The rust spores float in the air 
and settle upon the leaves, send their fungal threads down into the 
interior of the leaf, absorb the food and mineral nutrients of the 
plant, and cause a consequent dying of the leaves, reduction in growth 
and vigor of the plant, and its ultimate death. 
The plants which we are offering for sale this year have all 
been produced from hybrid seed, and are 90 to 95% rust resistant. 
We are able to offer these plants at the following popular prices: 
CHOICE MIXED COLORS—50c per doz.; 60c Postpaid; $2.50 
per flat (approximately six dozen in a flat). F. O. B. Sacramento. 
We have plants in separate shades of the following beautiful 
colors: White, Pink, Crimson, Dark Red, Red with White throat, 
Orange. 10c each; 2 for 15c; 4 for 25c; 75c per dozen. F. O. B. Sac¬ 
ramento. Plants of separate shades are in 3 inch pots. 
Contrast between ordinary commercial susceptible plants and our new 
Rust Proof Plants. 
Right: Ordinary Commercial Plant. Left: Our new Rust Resistant Plant. 
Both plants were grown under identical cultural conditions. They were arti¬ 
ficially innoculated with Rust Spores under optimum conditions for the spread 
of the disease. The ordinary Commercial Plant on the right has broken out 
with a severe infestation of Rust. One of our new Rust Resistant plants on the 
left remains completely immune to the disease. 
F. Lagomarsino and Sons through their plant breeding department and trial grounds have been 
carrying on a very extensive program of plant breeding work and investigation with these Snapdragons, 
in order to offer to the general flower trade choice flowering strains completely immune to rust. To 
accomplish this it has been necessary for us to perform much hybridization in the making of numerous 
carefully controlled crosses between various pedigreed lines of plants. This has required artificial in- 
noculation of hundreds of plants, rogueing out of less desirable ones, selecting but a few of the finest 
for the progenitors of future lines or strains, and growing large population of plants under specially con¬ 
trolled conditions. This tremendous task has resulted in our finally obtaining rust resistant plants which 
we arc offering as our new introduction for the year 1934. 
By rust resistant plants we do not mean plants which will 
become infected only slightly with the disease, or grow for a 
considerable period of time before becoming infected, but plants 
which are wholly immune to the disease—rust immune plants. 
These plants may be planted adjacent to diseased plants, or even 
have theii branches intertwined with susceptible plants entirely 
covered with the disease, and remain completely immune. 
Many experiments have been performed to discern some remedy 
which would be efficacious in combating this disease so universally 
present on Snapdragons. Bordo, sulphur, lime, and many more com¬ 
plex chemical dusts and solutions have all been tried with no 
appreciable success. The possibility was then conceived of attempting 
to produce a Snapdragon through scientific plant breeding methods 
which would be completely resistant or immune to rust. After several 
years of careful scientific plant breeding this feat has finally been 
accomplished. The University of -California Agricultural Experiment 
Station first began work on this problem and were successful in 
obtaining rust resistant Snapdragons. Small quantities of this seed 
were distributed to commercial companies who had plant breeding- 
facilities and equipment to carry on these strains, and produce rust 
resistant strains of better flowering quality, of more general adapt¬ 
ability to varied conditions, and of greater uniformity and higher per¬ 
fection in general.
