Aster alpinus ‘Goliath’ (Syn. Symphyotrichum)
Vivid colour from a tough little gem
The name ‘Goliath’ comes because the lilac-blue flowers are so very large.
They are giants for the size of the plant, and in comparison to the flowers of other Alpine Asters.
Aster alpinus ‘Goliath’ has wonderfully vivid lilac-blue petals, set off by large yellow daisy centres. So for a dwarf plant it really packs a big punch.
It blooms prolifically in late spring and early summer. Then there are some repeats again in autumn.
A gentle groundcover & pretty edger
The plants are very neat, compact and low growing.
So they form a neat groundcover, but only spreading gently.
They therefore make perfect groundcover for small gardens.
Multiple plants can be used together if a greater or faster spread is needed.
Alpine Asters are delightful used as a front edge in a garden bed, between rocks, or in decorative pots.
Where to use in the garden
Plant in Full Sun to Part Shade.
Alpine Asters love to be well drained, and thrive in rocky soil, shallow and poor soils or gravel gardens, because of the conditions in their native habitats. They also enjoy wind, and being well aired. Sadly they do not enjoy humid climates.
Tough & easy little groundcover
As a plant of rocky slopes, Alpine Asters are very frost hardy to well below -10C, as well as being able to withstand periods of dry and harsh light.
Alpine Asters are not particularly thirsty plants, though of course they will do better with regular water if it is available. They are rated as resistant to periods of drought once established.
Maintenance is very low, with really nothing to do aside from an occasional water.
Grow under roses
Alpine Asters respond best when kept on the lean side, so heavy or frequent feeding is never required. They are able to tolerate soil pH on both the acid or the alkaline lime side of neutral. If you can grow roses, you can grow Alpine Asters. And they do make lovely underplanting for roses.
