The Hosta Mill Collection

The collection

2002 - 2005 - The early years

According to my recollection and (mainly) my collection database, I seriously started collecting hostas in a structured way, with the purpose of building a collection, in 2002.

"In a structured way" might be slightly exaggerated: everything I liked and wasn't to heavy or to expensive, was dragged home to the Hosta Mill.  Dwarf and small hostas were off limits from day 1, because I believed the little stuff wouldn't fit into a large garden.

What was my "M.O." ? During winter months, I downloaded the available catalogues from the Low Lands on the web. Every catalogue was transformed into an Excel file.
Then the first rough selection was made: everything to expensive (over 15 $) and to small (dwarf, small, small-medium) was removed.
Next step: all remaining plants were looked up in the Hosta Library and given a score (out of 10), based on how nice the plant looked to me.  Once every plant was "judged", I could order them every way I wanted.  Mostly this boiled down to a ranking based on score and price: the cheapest plants with the highest score were on top,  plants with a lower score fell out of grace, as did more expensive plants with an average rating.

The final result in 2005 : a patchwork of about 200, mainly large, variegated hostas.
As long as they were kept in containers, the overall view was acceptable to a certain degree, but when I started to try and give every plant a place in the garden, soon I did realize this would never work for us.  I wanted a peaceful shade garden, and no matter how hard I tried, I couldn't fit in the 2005 collection: it was just to painful to the eyes.
During my many nursery visits, I learned to appreciate the more "quiet", simple hostas better.  Traits like leaf shape, plant shape, white backs, petiole color eventually became more important than all those flashy colors in the variegated stuff.

2006 - 2007 - New objectives

2006 was the first year the solid colored plants that arrived at the Hosta Mill outnumbered the variegated ones.  I still made up a wish list (I still do), but the final judgment was made at the nurseries, seeing the plants for real.  My taste in hostas had made a drastic change,  so drastic I decided to stop buying variegated plants all together, with only the odd exception allowed.

Because I was very pleased with the results my 2006-2007 seed experiments, and as I was gathering more and more knowledge on hostas at high speed, I started buying and collecting plants with higher potential for my hybridizing schemes to be.  The focus shifted even more to shapes of plants and leaves, texture, substance, red petioles, white backs and fronts, wavy and piecrusted edging, etc.  Every now and again a streaker was added, to have pod parents for my own variegated seedlings.

2008 - It's getting better all the time

Not much has changed in the hosta buying policy for this year.  The emphasis will be more on one of my  latest goals: the building of a collection of species, named clones of the species and sports from the wild or from horticulture + other plants (hybrids? - species?) from the wild.

Another (mainly financial) blessing is that buying is no longer the only way to extend the collection.  Many plants have reached adult size, and are ready for dividing and swapping. I've even played with the idea to sell of a number of the older variegated plants all together, but I have to admit, that's very hard to actually do.  We'll see about that later.

The trading thing can have some disadvantages as well: before you know it the collection grows so fast you're in danger of loosing your grip on it.  Collecting hosta, at least to me,  is a hobby, not nearly as important as our family life or my job; It should never give me more work than what I can handle in a reasonable space of time.

A review of plants I ordered so far

The plants I have received are marked green.

Plants for the species collection

You'll notice there are some variegated ones here.

Name Origin Description
H. capitata species species
H. 'Chishima Iwa' (Wild NR) Japan, Chishima Island.  Maybe a H. rectifolia morph ? Possibly a species. Mini, shiny dark green leaves have good substance and are quite wavy. Leaves held in a radial fashion and the clump is open. Lavender flowers.  This one fits in my "species and forms from the wild" collection.    My guess of it being some H. rectifolia morph is based on the general appearance (judging from a picture) and the location where it was found, which is in a general area where only H. rectifolia forms occur.
H. clausa var. clausa species species

H. clausa var. normalis (F. Maekawa 1937/AHS 1993)

species

Fuji, where it was found by Gotemba Nursery.

A vigorous, small hosta with an upright growing habit, a great way to show off the deep scarlet petioles, the color of ripe pie cherries.   Vibrant yellow leaves. It also sets plenty of viable seed. I'll have to find an elevated position where it can catch the sun and it really shows of those red legs.

H. 'Hacksaw' (Ken Livingston NR) H. 'Atom Smasher' x H. 'Stiletto' Small, rapidly growing plant with long narrow and tapered leaves which are intensely rippled and serrated.

H. 'Lakeside Lollipop' (M. Chastain 1993 ) unknown This small, low-growing plant, was so named because each leaf and its petiole is shaped like an old-time all-day sucker. The very dark green leaves are nearly round with a rounded base. They are flat and have a unique edge turning upward, thus providing further interest to the clump. Pure white flowers on well-proportioned scapes contrast with the leaves.

'Salute' Medium to large (24” X 47”) upright clump, wedge-shaped rich blue-green leaves, wonderfully rippled and cascading downward, to form a large flowing mound of foliage, a very attractive shape to me. Light lavender flowers open during August on arching stems. Impressive, even as a small plant
H. 'Paradise Island' (Marco Fransen 2005) H. 'Fire Island' sport Heart-shaped bright yellow leaves with a dark green margin. Yes, I know, it's not solid colored and it's not streaked.  When I saw it at Marco Fransen's nursery, I immediately fell in love with it and decided I needed it ... very badly.  
H. 'Pearl Lake' (Piedmont Gardens 1982)   15" tall. Light Shade.

H. 'Radio Waves' (G. Johnson 2004) H. 'Shining Tot' seedling Medium green; centre band of chartreuse in spring; very wavy; good substance. Extremely fast grower!.
A flash of variegation in spring, but the real value of this plant is in its attractive waviness and fast growth rate, making it an ideal edging plant or low ground cover.

Lavendar flowers in July.
H. 'Semperaurea' (Japan/K. Foerster/P. & J. Ruh 2003)   =sieboldiana 'Semperaurea'.
This is a very important plant historically, as it was the first known lutescent gold hosta, and possibly the first gold hosta of any kind.
