IRWIN’S QUALITY PLANTS and CUTTINGS 
CULTURAL DIRECTIONS BY WM. SIM & SON, THE INTRODUCERS OF 
MARY STUART, SILVERLYN AND LOCHINVAR: — 
Mary Stuart, Silverlyn and Lochinvar are fancy novelties which require more care than regular 
varieties. There is a market for these lovely novelties by the best flower buyers and retailers. 
| recommend the above varieties because they are free flowering and will pay any grower 
who grows them if handled according to directions. 
The above varieties should be pinched as late as Sept. 15th to 25th. By doing so, they will 
come truer to color showing the silver and orchid edging from late November and December and 
through the winter they will show their true markings. 
Calling on Mr. C. B. Johnson, Woburn, Mass. on November 23rd, !942 he showed me a bench 
of Silverlyn that he was proud of. He gave them the last pinch September | 5th. 
We are learning how to grow these fancy varieties. Last year we did not know that Silverlyn, 
Mary Stuart and Lochinvar should be pinched late to get flowers more true to color with better 
stems, etc. If you pinch these varieties as late as September |5th to 25th you will have good produc- 
tion from early December until Spring. 
Wm. Sim & Son, North Berwick, Maine, the introducers of Silverlyn, Mary Stuart and Lochinvar, 
grow these varieties and sell them in the Boston Flower Market and they average 2¢ more through the 
season than any other commercial varieties because they have something different. You can do the 
same! 
Mr. Sim also advised me that he found these novelty varieties do best in soil where the P.H. 
is around 6.5. For best results he recommends the use of superphosphate on all fancy varieties with 
silver or orchid edgings and by giving these varieties the extra care, they get a better price in the 
market.
