Brian7 said "Hi. I have a cheap vacation home. There is a small (not so small and not so big) flower bed (outside back yard) in the vacation home. I go to the vacation home only on weekends (Friday evening to Sunday). I want to plant some flowers or plants in the flower bed. Please recommend some flowers or plants that can survive by watering them only on weekends (preferably perennials). Also, please tell me where I can buy them (Walmart/Superstore/Home Depot/etc). "
It depends on how much sun the area gets. Any plants you plant will likely need regular watering until they are established. Often after the first year, you can cut back on water needed.
I’d recommend a local greenhouse like Alternative or the Greenspot over a big box store. They have staff that know what they’re doing and plants are taken care of better and in better condition. There is also a lady near Kemnay who sells hostas, peonies, lillies. Lindenberg’s is also a great place to check out.
You could go to any local greenhouse (is there one in the town you spend weekends in?) and receive great advice.
There are also plant sales this time of year. Brandon and Neepawa’s is this weekend.
Take longer to establish but if you can, you should choose native plants. They may take a bit more care up front but they are made to survive in our area and once they are established they are good to go. The Greenspot sells Prairie Originals which is a Manitoban native plant company.
If it is a shadier area, bleeding hearts are great. They fill in an area nicely, have pretty pink flowers and foliage looks pretty when they are done blooming. Ferns are great in shadier areas.
Hostas are great. They are very hardy. Many different varieties.
Day lilies are a bushier plant that flower. Pretty hardy.
Irises are very hardy.
Peonies are pretty. Love blanketflower. Yarrow is pretty and spread nicely. Milkweed is important for butterflies. Joe Pye, bergamot, coneflower, false sunflower, black eyed Susan are all good choices.
Some flowers reseed themselves easily. Like cosmos, pansies, dianthus, poppies. Zinnias are popular and grow quickly.
If cost is an issue, you can buy packets of perennial seeds and fill in your bed with them. Of course, it’s a bit slower to see results than if you’d bought plants.
You want to stay away from plants that are invasive like creeping bellflower, bishop goutweed, lily of the valley. Can find others by looking at the invasive species list.
