Forced Hyacinths have finished up in my greenhouse.
Today I planted out all that were left; some were planted out a week or more ago. Those in pots of soil were just eased from the pot. I teased the roots that had started to circle the bottom of the pot. Holding them upright in a hole, I poured dirt around and over the roots. Most of them will bloom again next year. Some take a year off. Some will split to have two bloom stalks.
Common Hyacinths Hyacinthus orientalis have contractile roots that pull the bulb deeper into the soil. Therefore I planted them near the top of the soil with the foliage outside. Potted tulips were growing with bulbs above soil level. They'll be safer covered with soil outside and can pull themselves deeper into sandy soil if needed.
When I compared the results of bulbs in water and stones with those in soil, I've decided to plant in soil in the future, after years of planting in stones. The foliage is bigger and in most cases the bloom was larger and fuller.
A bulb in soil does not have to use all its energy producing a blossom, drawing from the soil. Of course this year's bloom was formed by last year's foliage but nutrients are available at all times for forming foliage when planted in soil.
Bulbs that I planted in ground in the fall when I put bulbs for forcing in to chill are just coming out of the ground with buds visible. Bulbs planted in previous years are blooming, have already bloomed or are showing buds, depending on cultivar.
Hyacinths have a long season of bloom because there are early and late species. Hyacinths bloomed in sequence in the greenhouse for a month. Earliest hyacinths outside started blooming at the end of January.
Not only Dutch hyacinths, which are the full, round bloom stalks but Roman-type hyacinths are available. I like them for flower beds.
There really are no hard and fast rules for hyacinths except that they need some chill to properly bloom. The bulbs need support, whether in water and stones or in soil. You really can't have too many. Eight is a good number for a little clump in the garden.
I haven't shown white, nor pale yellow nor pale apricot Gypsy Queen because they haven't bloomed outside yet. I only forced pink, fuchsia and blue/purple indoors this year. The hardest part is choosing.
