Let's
hear it for hostas
|
Although hostas have
enjoyed the number one perennial spot in the USA for many
years, there is still some reluctance with UK gardeners to
give them a go.
This is a great shame because they are so versatile.
|
Hostas are essentially woodland
plants and flourish best in shady, well-drained (but not dry) soil.
Hostas enjoy a long season, usually emerging
in April, and will continue to give pleasure long after other plants
have died back. Indeed, many of the fragrant varieties come to their
peak towards late summer.
- Spring growth is a welcome sight, as the
new shoots poke their heads above the chilly soil. Even at this
stage, the different varieties are striving to show off their
individuality.
- Summer is
abundant as the hostas mature and the full value of them as architectural
and accent plants, comes to the fore.
- Autumn colour
is glorious with most varieties giving a last flourish before
entering their dormant phase, which last year wasn't until mid-November.
Creating shade
The problem of shade is easily overcome by under-planting
existing shrubs and trees with hostas. If your garden is devoid
of shady areas then perhaps pots are a good way to house your hostas
until other planting has matured enough for you to pop your hostas
in the ground. Pots can be left alongside walls and fences out of
direct sun - indeed why not locate some pots under pergolas and
grow some vigorous climbers, such as ivy or clematis to provide
shade. We have done this to great effect, even using patio umbrellas
in the heat of the day!
|
Pots are a good way for you to experiment with the location
of your hostas without the need to keep digging them up to move
them. |
Hostas look equally
stunning in pots but you
must ensure they do not dry out - they are less demanding on water
than hanging baskets but should be watered at least a couple of
times a week. Water more often when the weather is as dry and hot
as we experienced last year.
Hosta care
Hostas are extremely tolerant plants but you
cannot expect them to sit in water for prolonged periods or bake
in full sun. Having said that, some varieties are proving able to
withstand full sun, as we found during last year's show season.
Experience suggests to us that if a hosta has
cool roots and adequate moisture, it will take a reasonable amount
of early morning and late afternoon sun. However, if you prefer
the blue cultivars then the more shade you can give them the better
as this is what allows the bloom to develop on the leaves.
If your hosta is showing signs
of stress, i.e:
- the leaves have developed brown edges
- there is a proliferation of small leaves in the
centre of the plant mound
- flowering is occurring before the leaves have emerged
(if this happens, remove the flower head above the first pair
of leaves)
Don't be afraid to split
the plant as splitting is easy and the plants re-establish quickly,
so before long you will have several plants from that single purchase.
Infinite variety
Many hostas change colour and/or variegation
throughout the season - there are special terms for this:
- Viridescent: varieties
that begin the season with a distinct variegation and gradually
lose it as the season progresses.
- Lutescent: varieties
that begin the season with plain leaves, which then develop variegation
as the season progresses. Many lutescent varieties have the added
bonus of fragrant flowers.
- Albescent: varieties
which become paler as the season progresses.
It is often difficult to choose with so many
varieties now commercially available. If you are at a loss then
do consult us as we would be happy to try to steer to you towards
varieties that suit your growing conditions and demands. The best
way to do this is to visit us at the nursery where we can spend
some time with you. This year we are opening the nursery most Thursdays,
Fridays and Saturdays unless we are all at shows and we welcome
visitors outside of these times by appointment - see side column
for dates.
We look forward to seeing you this
year.
