Hosta
flowers bloom at different points in the summer season depending
on the habits of the original species. For new cultivar
registration purposes, The American Hosta Society has designated
6 bloom timeframes including:
Before June 1 |
July 15 to August 15 |
June 1 to 15 |
August 15 to October 1 |
June 15 to July 15 |
After October 1 |
As you might guess, the exact
dates that a particular cultivar will bloom in your garden will
be influenced by your location. For instance, generally, a plant
may flower a bit earlier in the season in South Carolina as
opposed to the same plant in Minnesota. Late season bloomers may
not have time to blossom and set seed in Northern gardens. This
is a challenge for hybridizers.
The registration form asks
applicants to also list the dates when the bloom started, hit
its peak and finished in the originator's garden. Some people
use the timeframes listed above while others just say "July" or
"August" or "late June".
So, we have entered those
descriptions into our database as they are found in various
references. We have listings based on the months of the summer
from June to October. This means that a plant that is listed as
"July 15 to August 15" will show up on the July, August
and July into August
lists.
