Fragrant hostas are important both because they
are fragrant (obviously), and, not so obviously, because they are often
recommended as the best hostas for warmer areas or for sunny locations.

'Fragrant Bouquet'
Depending on what you read and who
you believe, there are probably
twenty-something hosta species found in the wild, but only one, H. plantaginea, has fragrant flowers.
Every fragrant hosta is either a sport or a hybrid of
plantaginea. Not only is
it the only fragrant species, its pure white flowers are by far the largest
of any hosta, 5" or more in length and over 2" wide. No other species comes
anywhere close. Many of the fragrant hybrids have larger than normal flowers
also, but as far as I know, none are as large as the species.
If you live in the South, areas where the
winters aren't too cold and the summers are too hot, growing hostas can be
difficult. The further south you live, the more trouble you are going
to have. For those who grow hostas in warm winter areas, some varieties are
better than others. Because plantaginea is native to Southern China,
which is the warmest area of the genus' natural habitat,
it is more adapted to warmer climates than most hostas.
H. plantaginea is also known as the
August Lily, because it blooms so late in the season. It is a unique and beautiful
hosta, and you would think it would be one of our most popular plants.
And it probably would be, except that we don't grow it. For us, it is
nothing but trouble. Something in it's genes makes it among the first
of the hostas to break dormancy in the spring. That's probably fine in
southern China, but here in Virginia it often
gets hit by a late freeze after the leaves come up, turning them to mush.
A late freeze can lead to crown rot, which will sometimes kills the
plant, but more often the damage is limited to the leaves and the plant will eventually grow new foliage and fully
recover by the summer. While that may be acceptable in the garden, and with a bit of
effort even preventable, unreliable plants are not good for spring shipping
around here.
The other problem is that unless
the plant has a long summer growing season, it may not produce flowers.
Gardeners in the northern half of the country may find that it is not a
dependable bloomer, and without flowers, it's hardly worth the effort.
That doesn't mean that it can't be successfully grown in the North, just
that we've been disappointed enough times to decide that it's not worth the
trouble for us to grow.
For those who
can grow H. plantaginea successfully, we do try to offer it
after the danger of a hard freeze is over in our area, if we
can find it available from other growers. There are
many places in the country where it can be grown, in fact,
in warm winter areas it may be the best variety to to grow.
Actually, we can
grow plantaginea in our gardens here, because we can accept
that it will occasionally suffer severe leaf damage in the
spring. While that's something we can handle in our
own garden, it certainly wouldn't be acceptable for a plant
that we were sending to a customer.
We recommend that you try
the plant at least once. Even in the cold winter areas,
people have grown the plant for many years. Sometimes the
weather cooperates and sometimes it doesn't. It is
totally unique among hostas and if you can grow it you will
love it.
All is not
lost however. Many of the plantaginea hybrids,
especially 'Fragrant Bouquet' and its many sports have wonderfully fragrant
flowers. Admittedly they are not as large as the species, nor quite as
fragrant, but they come pretty close. And the hybrids generally break
dormancy later than the species and do not need as long a growing
season to produce flowers. While they still may need some
protection from a late frost, we have found them much easier to grow
in the North than the species.
And in the South, while the hybrids may
not be quite as heat tolerant as plantaginea, given adequate
water in the summer, they are probably better suited to hot, humid
conditions than most hostas. Because blue hostas in general do not
hold up well in the South, 'Fragrant Blue' may be an exception. |
