Tell Alyssa to go to these locations for the trees and shrubs,
(Pinea Wholesale) or (Crestwood Growers)
For fruit trees it will be The Home Depot
For basic garden Perennials the best price seems to be Lowe's, Walmart, and Pinea.
The best and largest supply of variety of each sub species will be J&L Garden retail.
(J & L only has a guarantee on trees and shrubs. Lowe's, Home Depot, and Walmart guarantee/warrantee all their plant stock.)
For exclusive Hosta... Lowe's and Hosta House.
Home Depot is in the middle of 50% off sales.
Don't buy shrubs from Home Depot at retail. If you go to Home Depot they will have a 2 foot tall pine tree for $25. But Walmart will have one the same size and variety for $12.
