Alpine plants perfect for rock gardens

1)Campanula(Bellflower)

Bellflowers are among the most popular of perennials. This comes from the mountains of Northern Spain.There are many types of them from short to tall with blue to purple flowers.Easily divided in spring or fall.The Dwarf Hybrid Bellflower  has a compact habit, making it ideal for rock gardens, edging, or growing in containers. Removing faded flowers will encourage repeat blooming.They need full or partial sun exposure. You can see some of them below.Most of them have hardiness zones between 5 and 8.The hardiness zones of Serbian bellflower and Peach-leaved bellflower are between 3 and 8. 

Campanula latiloba

Campanula bellidifolia

Campanula aucheri

Campanula betulifolia:is the only white campanula I,ve ever seen.They are so pretty and saxatile species from Armenia, Turkey and Iran where it grows in volcanic and limestone rock crevices.

Rock Gardening plants

Combination of rocks and stones being used as decorative elements can be traced back to early Chinese and Japanese gardens.Traditionally, alpine plants were used when planting rock gardens. These plants are native to mountainous regions and grow above the tree line. They've adapted to harsh conditions such as wind, cold, low moisture and a short growing season. Today, many plants are considered rock garden plants because of their slow growth habit, small stature and low-growing habit.I personally love rock gardens because there is not any specific rule for designing that and anybody can do that in a creative way.I love sedum plants as they don't need any particular maintenance and easy growing and absolutely stunning.There are many varieties of them in attractive colors.Do that in coming spring and add  a touch of the alpine to your landscape.

I will introduce the alpine and succulent plants,perfect for such gardens, soon.

Plant Hardiness Zones in Canada

The Plant Hardiness Zones map is divided into nine major zones,the coldest is 0 and the warmest is 8.There are some sub-zones as well.The coldest is 0 and the warmest is 8.It is based on the average climatic conditions of each area.The original one was created by Agriculture Canada Scientist in 1967 and was based on Canadian plant survival data and climate variables,like minimum winter temperatures,length of frost free periods,summer rainfall and etc.This is one of the most important factors when want to purchase any plant or seeds.It should be considered that whether any plant will survive under some particular factors of climate.The Plant Hardiness Zones in Canada was revised in 2000 and the effect of elevation was added to the equation.As a general rule, in Zone 6, you should plant plants hardy in Zone 6 and up to three zones colder. Plants hardy to Zone 8 would never survive the winter in your yard. So, although the zone map is a useful starting point for all of us, consider your own yard’s conditions and your area’s weather fluctuations when choosing yearly plantings.
